Introduction
Semaglutide is a medication that has gained a lot of attention in recent years. It is mainly used to treat type 2 diabetes and help with weight loss. But how does it affect your kidneys? This question is important because the kidneys play a vital role in keeping our bodies healthy. Understanding the effects of semaglutide on the kidneys can help people who are considering or currently using this medication make informed decisions about their health.
Semaglutide works by mimicking a hormone called GLP-1, which is naturally produced in the body. GLP-1 helps to regulate blood sugar levels by increasing insulin release after eating and slowing down the rate at which food leaves the stomach. This helps to keep blood sugar levels more stable. For people with type 2 diabetes, this can mean better control over their blood sugar levels. Additionally, semaglutide can help people lose weight, which is another important factor in managing diabetes.
The kidneys are two bean-shaped organs located near the middle of your back, just below the rib cage. They are responsible for filtering waste and extra fluids from your blood, which are then removed from your body as urine. The kidneys also help to regulate blood pressure, produce red blood cells, and keep your bones healthy. Because the kidneys do so much, it is important to ensure that any medication you take does not harm them.
There is a growing body of research looking at how semaglutide affects the kidneys. Some studies suggest that semaglutide may have protective effects on the kidneys. For example, it may help reduce the risk of kidney damage in people with diabetes. This is important because diabetes is a leading cause of kidney disease. By helping to control blood sugar levels and reduce weight, semaglutide might also help to reduce the strain on the kidneys.
However, like any medication, semaglutide may also have potential risks. Some people worry that it could cause kidney damage or make existing kidney problems worse. It is essential to understand these risks so that you can weigh them against the benefits of using semaglutide.

What is Semaglutide and How Does It Work?
Semaglutide is a medication primarily used to treat type 2 diabetes. It is also gaining popularity as a treatment for obesity. Understanding how semaglutide works and how it interacts with the kidneys is important for anyone considering this medication.
Description of Semaglutide
Semaglutide is a type of drug known as a GLP-1 receptor agonist. GLP-1 stands for glucagon-like peptide-1, which is a hormone that helps regulate blood sugar levels in the body. Semaglutide mimics the action of this hormone, helping to control blood sugar and reduce appetite. It is available under brand names such as Ozempic® and Wegovy®.
Mechanism of Action in the Body
To understand how semaglutide works, we need to look at what GLP-1 does in the body. GLP-1 is released in the intestines after eating. It stimulates the pancreas to release insulin, which helps lower blood sugar levels. Insulin allows cells to take in glucose (sugar) from the bloodstream to use for energy.
Semaglutide binds to the same receptors that GLP-1 does, which means it can perform similar actions. When you take semaglutide, it activates these receptors, leading to increased insulin production when blood sugar levels are high. It also reduces the amount of glucose produced by the liver. This helps keep blood sugar levels stable.
Another important effect of semaglutide is that it slows down the emptying of the stomach. This means food stays in the stomach longer, which helps you feel full for a longer period. This effect is particularly useful for people trying to lose weight, as it can reduce overall food intake.
Common Uses in Treating Diabetes and Obesity
Semaglutide is primarily used to manage type 2 diabetes. In type 2 diabetes, the body either does not produce enough insulin or cannot use insulin effectively. By increasing insulin production and reducing glucose production in the liver, semaglutide helps keep blood sugar levels under control. This can reduce the risk of complications associated with diabetes, such as heart disease, nerve damage, and kidney problems.
In addition to treating diabetes, semaglutide is also approved for weight management in people who are overweight or obese. By reducing appetite and increasing feelings of fullness, it helps people eat less and lose weight. Weight loss can have many health benefits, including improved blood sugar control, lower blood pressure, and reduced risk of heart disease.
Overview of How Semaglutide Interacts with the Kidneys
The kidneys play a crucial role in filtering waste products from the blood and maintaining overall fluid balance in the body. When discussing medications like semaglutide, it’s important to understand how they might affect kidney function.
Semaglutide is processed by the body and eventually excreted through the kidneys. This means that any changes in kidney function could potentially affect how the drug is processed and removed from the body. Conversely, the medication itself can have effects on kidney function.
One of the ways semaglutide may benefit the kidneys is by improving blood sugar control. High blood sugar levels can damage the small blood vessels in the kidneys, leading to a condition known as diabetic nephropathy. By helping to keep blood sugar levels in check, semaglutide can reduce the risk of this type of kidney damage.
Additionally, some studies have suggested that GLP-1 receptor agonists like semaglutide might have direct protective effects on the kidneys. These effects are still being researched, but they could potentially add to the benefits of using this medication.
Semaglutide is a medication that helps control blood sugar and reduce appetite by mimicking the action of the GLP-1 hormone. It is used to treat type 2 diabetes and obesity, offering significant health benefits. Understanding how semaglutide works and its interaction with the kidneys is crucial for anyone considering this medication.
Understanding Kidney Function
The kidneys are vital organs that play a crucial role in keeping our bodies healthy. Located on either side of the spine, just below the rib cage, these bean-shaped organs are about the size of a fist. Each kidney contains around a million tiny filtering units called nephrons. These nephrons help filter blood, remove waste, and balance fluids and electrolytes.
The Role of the Kidneys
The primary job of the kidneys is to filter blood. Every day, the kidneys filter about 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. Here are some key functions of the kidneys:
- Removing Waste Products: The kidneys remove waste products and excess substances from the blood, which are then excreted as urine. Waste products include urea (a byproduct of protein metabolism) and creatinine (a byproduct of muscle activity).
- Balancing Body Fluids: The kidneys regulate the balance of fluids in the body. They ensure that we have the right amount of water in our blood by either conserving water if we are dehydrated or making more urine to get rid of excess water if we are overhydrated.
- Regulating Electrolytes: Electrolytes such as sodium, potassium, and calcium are crucial for the function of our cells and organs. The kidneys help maintain the proper balance of these electrolytes.
- Controlling Blood Pressure: The kidneys produce an enzyme called renin that helps control blood pressure. They also adjust the amount of sodium and water in the blood, which can affect blood pressure levels.
- Producing Hormones: The kidneys produce hormones that are important for bone health and red blood cell production. For example, they produce erythropoietin, which stimulates the production of red blood cells in the bone marrow.
How Medications Impact Kidney Function
Medications can affect the kidneys in various ways. Some drugs can change the way the kidneys filter blood, while others can affect how the kidneys balance fluids and electrolytes. Here are a few ways medications might impact kidney function:
- Direct Damage to Kidney Cells: Some medications can be toxic to the cells in the kidneys. This can lead to a condition called acute kidney injury, where the kidneys suddenly stop working properly. Examples of such medications include certain antibiotics and pain relievers like nonsteroidal anti-inflammatory drugs (NSAIDs).
- Changes in Blood Flow to the Kidneys: Some drugs can alter blood flow to the kidneys, which can affect their ability to filter blood. For example, certain blood pressure medications can reduce blood flow to the kidneys.
- Electrolyte Imbalance: Medications can also affect the balance of electrolytes in the body. For instance, diuretics (water pills) can cause the kidneys to remove too much potassium, leading to a dangerous imbalance.
- Increased Waste Products: Some medications can increase the production of waste products in the body. If the kidneys are not able to filter these waste products effectively, they can accumulate in the blood and cause harm.
Protecting Kidney Health
Given the crucial role the kidneys play, it is important to protect their health, especially when taking medications like semaglutide. Here are some tips for maintaining healthy kidneys:
- Stay Hydrated: Drinking plenty of water helps the kidneys remove waste from the blood. Aim to drink about 8 cups of water a day, more if you are physically active or live in a hot climate.
- Monitor Kidney Function: Regular check-ups with your healthcare provider can help monitor kidney function. Blood tests and urine tests can detect early signs of kidney problems.
- Be Cautious with Medications: Always follow your healthcare provider’s instructions when taking medications. Do not take more than the prescribed dose, and avoid over-the-counter medications that can harm the kidneys unless advised by your doctor.
- Maintain a Healthy Diet: Eating a balanced diet with plenty of fruits and vegetables supports overall health, including kidney function. Limit salt intake to help control blood pressure and reduce the workload on the kidneys.
- Exercise Regularly: Physical activity can help maintain a healthy weight and lower blood pressure, both of which are important for kidney health.
By understanding how the kidneys work and how medications like semaglutide can affect them, you can take steps to protect your kidney health and ensure that your treatment is both safe and effective.
How Does Semaglutide Affect the Kidneys?
Semaglutide, known for its brand names Ozempic® and Wegovy®, is a medication primarily used to treat type 2 diabetes and obesity. While it offers significant benefits for controlling blood sugar levels and promoting weight loss, it is essential to understand its effects on the kidneys.
Current Research on Semaglutide’s Effects on the Kidneys
Studies on semaglutide have shown that it can have both positive and negative effects on kidney function. Clinical trials indicate that semaglutide may help protect the kidneys by improving blood sugar control, reducing inflammation, and decreasing the amount of protein in the urine (a marker of kidney damage). However, some patients have reported adverse effects, such as an increased risk of acute kidney injury, especially when starting the medication or adjusting the dose.
In a large clinical trial known as the SUSTAIN-6 study, researchers examined the cardiovascular and kidney outcomes of semaglutide in patients with type 2 diabetes. The results suggested that semaglutide could reduce the risk of new or worsening kidney disease. This is encouraging news, as it indicates that semaglutide may offer protective benefits for the kidneys, particularly in patients with diabetes who are at higher risk of kidney problems.
Mechanisms by Which Semaglutide May Influence Kidney Function
Semaglutide belongs to a class of medications called GLP-1 receptor agonists. GLP-1 (glucagon-like peptide-1) is a hormone that helps regulate blood sugar levels by stimulating insulin release, reducing glucose production in the liver, and slowing down the digestion of food. By mimicking the effects of GLP-1, semaglutide helps lower blood sugar levels and promote weight loss.
The kidneys play a crucial role in filtering waste products from the blood and maintaining fluid and electrolyte balance. High blood sugar levels can damage the small blood vessels in the kidneys, leading to a condition called diabetic nephropathy, which is a leading cause of kidney failure. By improving blood sugar control, semaglutide can help reduce the risk of developing diabetic nephropathy and slow the progression of kidney disease in patients with diabetes.
Semaglutide may also have anti-inflammatory properties, which can help protect the kidneys from damage. Inflammation is a key factor in the development and progression of chronic kidney disease, and reducing inflammation can help preserve kidney function.
Another way semaglutide may benefit the kidneys is by decreasing the amount of protein in the urine, known as proteinuria. Proteinuria is a sign of kidney damage and is associated with a higher risk of kidney disease progression. By reducing proteinuria, semaglutide may help protect the kidneys and improve overall kidney health.
Comparison with Other Medications in Its Class
Semaglutide is one of several GLP-1 receptor agonists available for the treatment of type 2 diabetes and obesity. Other medications in this class include liraglutide (Victoza®), dulaglutide (Trulicity®), and exenatide (Byetta®). Like semaglutide, these medications have been shown to improve blood sugar control and promote weight loss, but they may have different effects on the kidneys.
For example, liraglutide has also been shown to reduce the risk of new or worsening kidney disease in patients with type 2 diabetes, but the degree of benefit may vary between individuals. Dulaglutide has demonstrated similar kidney-protective effects in clinical trials, while exenatide has been associated with a lower risk of kidney-related side effects.
It’s important to note that while GLP-1 receptor agonists can offer kidney-protective benefits, they are not without risks. Some patients may experience side effects such as nausea, vomiting, and diarrhea, which can lead to dehydration and potentially worsen kidney function. Additionally, there have been reports of acute kidney injury in patients taking these medications, particularly when starting or adjusting the dose.
Semaglutide appears to have both beneficial and potentially harmful effects on the kidneys. By improving blood sugar control, reducing inflammation, and decreasing proteinuria, semaglutide can help protect the kidneys and reduce the risk of diabetic nephropathy. However, it is essential to monitor kidney function regularly and be aware of the potential risks, especially when starting or adjusting the medication. As with any medication, it is important to discuss the potential benefits and risks with your healthcare provider to determine the best treatment plan for your individual needs.
Can Semaglutide Cause Kidney Damage?
Semaglutide, a medication often used to manage diabetes and assist with weight loss, has become popular due to its effectiveness. However, one crucial concern that patients and healthcare providers share is whether semaglutide can cause kidney damage. In this section, we’ll explore the potential risks, review clinical studies, and discuss factors that may increase the risk of kidney damage.
Potential Risks of Kidney Damage with Semaglutide Use
While semaglutide is generally considered safe, like any medication, it can have side effects. The kidneys are vital organs that filter waste from the blood, regulate fluid balance, and perform other essential functions. Because semaglutide affects blood sugar levels and metabolism, it can also impact the kidneys.
One of the potential risks associated with semaglutide use is dehydration. Semaglutide can cause nausea and vomiting, which might lead to reduced fluid intake. Dehydration can strain the kidneys, making it harder for them to function correctly. In severe cases, this can lead to acute kidney injury, a sudden loss of kidney function.
Another concern is the potential for semaglutide to affect kidney filtration. Some studies suggest that GLP-1 receptor agonists, the class of drugs to which semaglutide belongs, might alter how the kidneys filter blood. This change could potentially lead to protein leakage in the urine (proteinuria), which is a sign of kidney damage.
Review of Clinical Studies and Patient Data
To understand the risks better, let’s look at what the research says. Clinical studies on semaglutide have shown mixed results regarding its effects on the kidneys.
In some studies, patients using semaglutide showed no significant changes in kidney function compared to those using other diabetes medications. These studies suggest that semaglutide does not cause noticeable harm to the kidneys in the general population.
However, other studies have reported cases of acute kidney injury and proteinuria in patients using semaglutide. For example, a study published in the journal Diabetes Care found that while the overall risk of kidney problems was low, there were isolated incidents of kidney injury. The study emphasized that these incidents were rare and often linked to other risk factors like dehydration or pre-existing kidney conditions.
Factors That May Increase the Risk of Kidney Damage
Several factors can increase the risk of kidney damage when using semaglutide. Understanding these factors can help patients and healthcare providers take preventive measures.
- Pre-existing Kidney Conditions: Patients with chronic kidney disease (CKD) or reduced kidney function are at higher risk. Semaglutide can potentially exacerbate these conditions, leading to further kidney damage.
- Dehydration: As mentioned earlier, dehydration can strain the kidneys. Patients who experience significant nausea, vomiting, or diarrhea while taking semaglutide should ensure they stay hydrated to protect their kidneys.
- Age: Older adults are more susceptible to kidney problems. Age-related decline in kidney function means that elderly patients should be monitored closely when using semaglutide.
- Concurrent Medications: Some medications can interact with semaglutide and increase the risk of kidney damage. For example, nonsteroidal anti-inflammatory drugs (NSAIDs) and certain blood pressure medications can affect kidney function. Patients should inform their healthcare providers about all the medications they are taking to avoid harmful interactions.
- Diabetes-Related Complications: Patients with long-standing diabetes may have underlying kidney issues due to the disease itself. These individuals should be particularly vigilant about monitoring their kidney function while on semaglutide.
Monitoring and Prevention
To minimize the risk of kidney damage, regular monitoring is essential. Patients taking semaglutide should have their kidney function tested periodically. These tests typically include blood tests to measure creatinine levels and urine tests to check for proteinuria. Keeping these tests up to date helps detect any early signs of kidney problems.
Additionally, patients should maintain good hydration, follow a balanced diet, and manage their blood sugar levels effectively. These steps can help support overall kidney health and reduce the risk of complications.
While semaglutide has been associated with some cases of kidney damage, these incidents are relatively rare. By understanding the risks and taking preventive measures, patients can safely use semaglutide under the guidance of their healthcare providers.
What are the Symptoms of Kidney Problems?
Recognizing the symptoms of kidney problems is crucial, especially if you are using semaglutide. Kidneys are vital organs that filter waste from your blood, control your body’s fluid balance, and regulate electrolytes. When kidneys are not working well, your body can experience a range of symptoms. Here’s what to look out for:
Common Signs and Symptoms of Kidney Issues
- Fatigue and Weakness: One of the first signs of kidney problems is feeling very tired and weak. When your kidneys are not filtering properly, toxins build up in your blood. This can make you feel exhausted, even if you are getting enough sleep.
- Swelling (Edema): Kidneys help balance fluid in your body. If they are not working well, you may notice swelling in your feet, ankles, or hands. This happens because your body retains more fluid than it should.
- Changes in Urination: Pay attention to your urination patterns. Kidney issues can cause you to urinate more often, especially at night. You might also notice that your urine is foamy, dark, or contains blood. Another sign is urinating less often or in smaller amounts than usual.
- Shortness of Breath: When kidneys fail to remove enough fluid from your body, it can build up in your lungs, making it hard to breathe. This symptom might be mistaken for other conditions, like heart problems or respiratory issues.
- Persistent Itching: Excess waste in the blood can cause severe itching. If you find yourself scratching often and without relief, it could be a sign of kidney trouble.
- Nausea and Vomiting: Kidney dysfunction can lead to a buildup of waste products in your blood, causing nausea and vomiting. This is more common in advanced kidney disease.
- Loss of Appetite: Along with nausea, you might lose your appetite. This can lead to weight loss and nutritional deficiencies, which further weaken your body.
- Difficulty Concentrating: High levels of toxins in the blood can affect your brain, making it hard to concentrate or remember things. You might feel confused or have trouble focusing on simple tasks.
How to Recognize Early Signs of Kidney Problems
Recognizing kidney issues early can help prevent more serious complications. Here are some tips on what to do:
- Monitor Your Symptoms: Keep a diary of any symptoms you notice, even if they seem minor. Track how often they occur and their severity.
- Check Your Urine: Pay attention to changes in your urine’s color, frequency, and volume. If you notice any blood or if your urine looks unusually foamy, contact your doctor.
- Watch for Swelling: Check your legs, ankles, and hands for any signs of swelling. Press on the swollen area gently; if it leaves a dent, it’s called “pitting edema” and is a sign of fluid retention.
- Listen to Your Body: If you are unusually tired, have shortness of breath, or experience any of the symptoms mentioned above, don’t ignore them.
When to Seek Medical Advice
It’s important to seek medical advice if you experience any of the symptoms of kidney problems. Here’s when you should contact your healthcare provider:

How to Monitor Kidney Health While Using Semaglutide
Monitoring your kidney health while taking semaglutide is essential to ensure that your kidneys are functioning properly and to catch any potential issues early. This section will guide you through the importance of regular kidney function tests, the types of tests used, and how often you should have these tests done.
Importance of Regular Kidney Function Tests
Regular kidney function tests are crucial for anyone taking semaglutide. These tests help your doctor see how well your kidneys are working and can detect any early signs of damage. Since semaglutide can affect the kidneys, it is important to monitor their health closely. Catching any problems early can make treatment more effective and prevent more serious issues later on.
Types of Tests Used to Monitor Kidney Health
There are several tests your doctor might use to check your kidney function:
Blood tests are a common way to monitor kidney health. A serum creatinine test measures the level of creatinine in your blood. Creatinine is a waste product that your kidneys normally filter out. High levels of creatinine in your blood can be a sign that your kidneys are not working well. Another important blood test is the blood urea nitrogen (BUN) test, which measures the amount of nitrogen in your blood that comes from the waste product urea. Like creatinine, high levels of BUN can indicate that your kidneys are not functioning properly. The glomerular filtration rate (GFR) test estimates how well your kidneys are filtering blood. A low GFR can indicate kidney disease or decreased kidney function.
Urine tests are also essential for monitoring kidney health. A urinalysis checks for the presence of protein, blood, or other substances in your urine that can indicate kidney problems. Another urine test, the albumin-to-creatinine ratio (ACR), measures the amount of albumin (a type of protein) in your urine. Normally, your urine should have very little or no albumin. High levels of albumin can be a sign of kidney damage.
How Often Should Tests Be Performed
The frequency of these tests depends on your individual health condition and risk factors. Your doctor will provide specific recommendations based on your needs. Generally, if you have diabetes or another condition that affects your kidneys, you may need to have these tests more often.
For most people taking semaglutide, your doctor may recommend testing every three to six months. If you have pre-existing kidney problems or other risk factors, your doctor might suggest more frequent testing. It’s important to follow your doctor’s advice and keep all your scheduled appointments for these tests.
What to Expect During Tests
Blood tests are usually straightforward. A healthcare provider will draw a small amount of blood from a vein in your arm. This process is quick and typically causes only minor discomfort. The blood sample is then sent to a lab for analysis.
For urine tests, you will need to provide a urine sample. For a urinalysis, you simply need to urinate into a clean container. For the albumin-to-creatinine ratio test, you might need to collect your urine over a 24-hour period, but often a single sample is sufficient.
Understanding Test Results
Your doctor will review your test results with you. If your creatinine or BUN levels are high, or if your GFR is low, it may indicate that your kidneys are not functioning properly. High levels of protein in your urine can also be a sign of kidney damage. If any of these results are abnormal, your doctor will discuss the next steps, which may include additional testing or changes to your treatment plan.
Taking Action Based on Test Results
If your test results show signs of kidney problems, your doctor may adjust your semaglutide dosage or switch you to a different medication. They may also recommend lifestyle changes to support your kidney health, such as staying hydrated, eating a balanced diet, and avoiding medications that can harm the kidneys.
Regular monitoring of kidney function is essential for anyone taking semaglutide. By understanding the importance of these tests, the types of tests used, and how often they should be performed, you can take proactive steps to maintain your kidney health and address any potential issues early. Always follow your doctor’s recommendations and keep all your scheduled appointments for the best outcomes.

One of the primary concerns is whether semaglutide can cause kidney damage. While clinical studies indicate that serious kidney issues are rare, there are some potential risks, particularly for individuals with pre-existing kidney conditions or other risk factors. Symptoms of kidney problems can include swelling in the legs and ankles, fatigue, nausea, and changes in urine output. Recognizing these signs early and seeking medical advice is essential.
Certain groups are at higher risk of developing kidney problems while using semaglutide. These include people with pre-existing kidney disease, older adults, and those with other health conditions that may affect the kidneys. Monitoring kidney health through regular tests is crucial for these individuals. Tests such as blood creatinine levels and urine albumin tests help assess kidney function and detect any issues early.
Managing kidney health while on semaglutide involves several proactive steps. Staying well-hydrated is vital, as dehydration can put additional strain on the kidneys. A balanced diet low in sodium and rich in fruits and vegetables can also support kidney health. Regular physical activity and maintaining a healthy weight are beneficial, too.
If you experience any symptoms of kidney issues while taking semaglutide, it’s important to seek medical attention immediately. Your healthcare provider can evaluate your symptoms and may adjust your treatment plan if necessary. This might include changing your dosage or exploring alternative medications that are safer for your kidneys.
In conclusion, while semaglutide is an effective medication for managing type 2 diabetes and obesity, it is important to be mindful of its potential impact on the kidneys. Regular monitoring, a healthy lifestyle, and open communication with your healthcare provider are key to maintaining kidney health. By taking these steps, you can minimize risks and continue to benefit from the positive effects of semaglutide on your overall health. Always discuss any concerns or symptoms with your healthcare provider to ensure the best possible outcomes while using this medication.

Questions and Answers: Semaglutide and Kidneys
Semaglutide is a medication used to treat type 2 diabetes and obesity. It mimics the hormone GLP-1 (glucagon-like peptide-1) to help regulate blood sugar levels, promote weight loss, and improve glycemic control.
Semaglutide can have both positive and negative effects on the kidneys. It may improve kidney function by reducing blood sugar levels, which can decrease the risk of diabetic nephropathy. However, like any medication, it can also have potential side effects that may affect kidney function in some individuals.
There is limited evidence suggesting that semaglutide can cause kidney damage. Most studies indicate that it has a neutral or protective effect on the kidneys. However, individual responses can vary, and some people may experience adverse effects.
Semaglutide can be used in patients with mild to moderate CKD. However, it should be used with caution and under medical supervision. Patients with severe CKD or end-stage renal disease should consult their healthcare provider before starting semaglutide.
The dosing of semaglutide does not require adjustment based on kidney function. However, healthcare providers should monitor kidney function regularly in patients with existing kidney issues to ensure the medication is not adversely affecting their kidneys.
Signs of kidney problems can include decreased urine output, swelling in the legs or ankles, fatigue, nausea, and confusion. If any of these symptoms occur, patients should contact their healthcare provider immediately.
Studies have shown that semaglutide may reduce the risk of kidney disease in diabetics by improving blood sugar control and reducing the progression of diabetic nephropathy. It helps in managing risk factors that contribute to kidney damage.
Semaglutide has been shown to potentially improve kidney function by lowering blood glucose levels and blood pressure, both of which are critical factors in maintaining kidney health in diabetic patients.
Patients with kidney disease should be closely monitored for changes in kidney function, electrolyte levels, and hydration status. Regular follow-ups with a healthcare provider are essential to adjust the treatment plan as needed.
Semaglutide can interact with other medications that affect the kidneys, such as certain diuretics and medications used to treat high blood pressure. It’s important for patients to inform their healthcare provider of all medications they are taking to avoid potential interactions.
