Questions about Ozempic and interactions

Here you’ll find answers to some common questions about Ozempic and possible interactions.

Can I take ibuprofen with Ozempic? Are there interactions between Ozempic and NSAIDs?

Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs) aren’t known to interact with Ozempic. These medications should be safe to take together if your doctor agrees it’s safe for you.

Still, ibuprofen and other NSAIDs have many interactions with other medications and health conditions. Although they don’t interact with Ozempic, they may interact with other health conditions you have or medications you take.

Because of this, you shouldn’t take ibuprofen or another NSAID without first talking with your doctor or pharmacist. They can help determine whether they’re safe for you to take.

Are there interactions between Ozempic and antidepressants?

No, it’s not believed so. There isn’t a known interaction between Ozempic and antidepressant drugs, such as sertraline (Zoloft). Antidepressants are used to treat certain mental health conditions, such as depression and anxiety. These medications should be safe to take together if your doctor agrees it’s safe for you.

But Ozempic may affect how your body absorbs oral medications, including antidepressants. It’s not known whether this has any effect on how well antidepressants work.

But it’s possible that Ozempic could cause an oral antidepressant to not work as well. This interaction can happen even if you’ve taken the antidepressant for a long time and it’s worked well for you.

Because of this, your doctor may closely monitor you if you take an antidepressant and Ozempic. This helps your doctor determine whether the antidepressant is still effective for your condition.

Your doctor or pharmacist can answer questions you may have about whether Ozempic can affect how well your antidepressant works.

Can I take Ozempic with antibiotics?

There isn’t a known interaction between Ozempic and antibiotic drugs, such as ciprofloxacin (Cipro). These medications should be safe to take together if your doctor agrees it’s safe for you. Antibiotics are used to treat bacterial infections.

That said, it’s possible for Ozempic to affect how your body absorbs any medication you swallow. This includes oral antibiotics.

For this reason, your doctor may closely monitor you if you’re taking an antibiotic while using Ozempic. This is to make sure the antibiotic is working as intended.

Talk with your doctor or pharmacist if you have questions about taking an antibiotic while using Ozempic.

Can I take Tylenol with Ozempic?

There isn’t a known interaction between Ozempic and Tylenol (acetaminophen). These medications should be safe to take together if your doctor agrees it’s safe for you. Tylenol is used to treat mild to moderate pain due to certain conditions.

But Ozempic may affect how your body absorbs any oral medications you take. It’s not known whether this has any effect on how well Tylenol works. But it’s possible that Tylenol may not work as well if you’re also taking Ozempic.

Also, there are other medications and health conditions that can interact with Tylenol. This can affect whether or not Tylenol is safe for you to take.

To learn more about taking Tylenol with Ozempic, talk with your doctor or pharmacist. They can answer any questions you have about whether Tylenol is safe for you.

Can I take Imodium with Ozempic?

There isn’t a known interaction between Ozempic and Imodium (loperamide). These medications should be safe to take together if your doctor agrees it’s safe for you. Imodium is used to treat sudden diarrhea.

But Ozempic can affect the absorption of any medication you swallow, including Imodium. This means it’s possible for Ozempic to affect how well Imodium works.

Diarrhea is a common side effect of taking Ozempic, especially when you first start taking it. If you experience diarrhea while taking Ozempic, let your doctor know.

They can help determine whether Imodium may help relieve your symptoms or whether another treatment for diarrhea may be better instead.

Is there an interaction between Ozempic and Adderall?

There isn’t a known interaction between Ozempic and Adderall (amphetamine/dextroamphetamine). These medications should be safe to take together if your doctor agrees it’s safe for you. Adderall is commonly used for attention deficit hyperactivity disorder (ADHD).

But Ozempic may affect how your body absorbs any oral medications you take, including Adderall. So it’s possible that Ozempic could cause Adderall to not work as usual.

If you’re taking Ozempic and Adderall, your doctor may closely monitor you for any signs that Adderall isn’t working as expected. They can also discuss treatment options if this interaction is affecting you.

When to avoid Ozempic

Certain health conditions or other factors could increase some risks with Ozempic. Because of this, doctors may not prescribe Ozempic in these cases. These health conditions or other factors are called contraindications.

Here’s a list of contraindications for Ozempic:

  • Personal or family history of medullary thyroid carcinoma (MTC): Taking Ozempic may worsen MTC (a type of thyroid cancer).*
  • Personal history of multiple endocrine neoplasia syndrome type 2 (MEN2): If you have MEN2, taking Ozempic may increase your risk of thyroid cancer further. MEN2 is a kind of genetic endocrine condition that can lead to thyroid cancer.*
  • Past allergic reaction to Ozempic: If you’ve ever had an allergic reaction to Ozempic or its ingredients, taking it again may cause another allergic reaction. This may include Wegovy and Rybelsus, which contain semaglutide, the active ingredient in Ozempic. An active ingredient is what makes medication work.

Before you start taking Ozempic, tell your doctor if anything listed above relates to you. They can recommend whether you should take Ozempic.

Boxed warning for Ozempic

Ozempic has a boxed warning for the risk of thyroid cancer. A boxed warning is the most serious warning from the FDA.

In animal studies, Ozempic and drugs similar to it raised the risk of certain thyroid cancers in animals. It’s not known if this risk applies to people taking Ozempic. Animal studies don’t always predict what effects a drug will have on humans.

Because of this risk, doctors won’t prescribe Ozempic if you or a close family member ever had a type of thyroid cancer called MTC. Doctors also won’t prescribe Ozempic or drugs like it if you have an endocrine condition called multiple endocrine neoplasia syndrome type 2.

During treatment, your doctor will monitor you closely for symptoms of thyroid cancer. Let your doctor know if you notice symptoms, such as hoarse voice or difficulty swallowing.

To learn more, talk with your doctor.
