How Long Does Ozempic Stay in Your System? What This Means for Side Effects and More

Key takeaways:

  • Ozempic (semaglutide) is an injectable medication that's approved to treat Type 2 diabetes in adults. Ozempic lasts a long time in the body, which is why you only need to inject it once a week.

  • For most people, Ozempic can stay in your system for around 5 weeks after your last dose. However, the time period may be different if you don't have diabetes.

  • You may be told to stop taking Ozempic at least 1 week before surgery to avoid potential complications. And if you want to become pregnant, you may need to stop taking Ozempic at least 2 months before trying to conceive so it's fully out of your system.

Ozempic (semaglutide) is an injectable medication used to treat Type 2 diabetes in adults. Compared to shorter-acting medications in its class, Ozempic offers the convenience of less frequent, once-weekly injections because it's made to last longer in the body.

You may not always think about how long a medication stays in your system. But in the case of Ozempic, it's an important consideration if you're scheduling a surgery or planning on becoming pregnant. And if you plan to stop taking Ozempic due to side effects, this information can give you an idea as to when they should resolve.

So, how long does Ozempic stay in your system, and why does it matter?

EXPERT PICKS: WHAT TO READ NEXT

How long does Ozempic stay in your system?

It's estimated that Ozempic stays in your system for around 5 weeks after your last dose. That's because it takes 7 days for your body to remove half of it, which is called its half-life. In general, it takes about five half-lives for most of a medication to leave the body.

Keep in mind that Ozempic is only approved for adults with Type 2 diabetes. If you don't have diabetes and have been prescribed Ozempic for a different reason, it's possible that your body might clear Ozempic at a slower rate.

Can you flush Ozempic out of your system?

No. You can't flush Ozempic out of your system.

After you inject Ozempic, most of it binds to proteins in your blood called albumin. This helps Ozempic last longer in your body so you don't have to inject it as often. But, this can also make it difficult to remove Ozempic from your body, such as in cases where you've accidentally injected too much. If this happens, contact Poison Control at 1-800-222-1222 for guidance.

If you stop taking Ozempic, you can't make the side effects go away sooner. You'll have to wait it out. More on this later.

Considerations for how long Ozempic stays in your system

How long Ozempic stays in your system matters in a few different situations. Surgery and pregnancy are two examples, but it can also affect how long side effects last after stopping Ozempic.

Stopping Ozempic before surgery

Ozempic slows down how quickly food moves out of your stomach (called gastric emptying). This can cause a problem if you're getting surgery. That's because even if you've avoided food and drink for a recommended period of time, your stomach still may not be empty. Anything that's left can come back up and get into your lungs while you're under general anesthesia.

If you're scheduled to undergo a surgical procedure, you may be instructed to stop taking Ozempic at least 1 week beforehand. Some Ozempic will still be in your system, but it may have less of an effect on your gut. If you still have slowed gastric emptying symptoms on your surgery day, such as nausea, vomiting, and bloating, you may be advised to reschedule the procedure.

Stopping Ozempic before pregnancy

The use of Ozempic hasn't been studied extensively during pregnancy in humans, so the potential risks aren't fully known. But animal studies have shown a higher risk of pregnancy loss and birth defects with Ozempic. Because of this, Ozempic isn't usually recommended during pregnancy.

If you're planning on becoming pregnant, your healthcare team will likely have you stop taking Ozempic at least 2 months before you start trying to conceive. This helps to ensure that Ozempic is completely out of your system in advance.

There may be certain situations where Ozempic's benefits outweigh its potential risks during pregnancy. Your healthcare team will discuss your options with you.

Stopping Ozempic due to side effects

Ozempic is known for causing side effects that can make it difficult for some people to tolerate. Examples of these include nausea, vomiting, and diarrhea. If this sounds like your situation, your prescriber may have you stop taking Ozempic.

Due to its long half-life, Ozempic's side effects may not resolve right away after you've stopped taking it. However, they should continue to improve as your body clears Ozempic. In the meantime, there are things you can do to manage nausea, diarrhea, and other side effects from the medication, such as eating bland foods for a period of time.

Can you stop taking Ozempic cold turkey?

Generally, yes.

Some medications can cause withdrawal symptoms or other serious side effects if you stop taking them abruptly. Ozempic isn't known to cause withdrawal symptoms in the traditional sense. But some people experience noticeable rebound effects, such as an increase in their appetite, which can result in weight gain. And if you have Type 2 diabetes, your blood glucose levels may be higher, especially after you eat.

When stopping Ozempic, you don't necessarily need to taper off of it. However, it's possible that your prescriber may recommend this approach for you. Talk to them first before trying to stop Ozempic on your own. Leaving your blood glucose unmanaged can increase the risk of diabetes complications.

Frequently asked questions

Do you have to take Ozempic forever to keep weight off?
expand_more

Ozempic isn't approved for weight loss. But if you lose weight while taking Ozempic, you generally need to keep taking it to maintain the weight you've lost. However, people decide to stop taking Ozempic for a variety of reasons. In this case, some research suggests that slowly tapering off the medication, along with lifestyle changes, may help with rebound weight gain.

What is the biggest side effect of Ozempic?
expand_more

Nausea is one of the biggest side effects of Ozempic, especially when you first start the medication and after dose increases. This is one of the reasons why you'll start with a low dose that's increased slowly over a few months. For many people, nausea improves over time and can be managed with dietary and lifestyle changes.

How do you break a plateau on Ozempic?
expand_more

Many people are able to lose weight with Ozempic, but this isn't the case for everyone. And some people start losing weight sooner than others. It's also common for weight loss to slow down or stop at a certain point. If you've hit a plateau with Ozempic, it helps to look at your specific dose, if you're taking the medication as directed, and what types of lifestyle and dietary changes you've incorporated into your routine.

If you aren't getting the results you want with Ozempic, your prescriber may consider increasing your dose, switching you to a different medication, or have you adjust your diet or movement routine.

The bottom line

Ozempic (semaglutide) is a Type 2 diabetes medication that you only need to inject once a week due to its long half-life. And after you've stopped taking Ozempic, it takes about 5 weeks for your system to clear most of it. Side effects should improve over this time.

If you're scheduling a surgery or trying to become pregnant, you'll likely be told to stop taking Ozempic for a recommended amount of time beforehand. This helps minimize potential risks that can occur in these situations.
