Mounjaro (tirzepatide) is a prescription drug that’s used to treat type 2 diabetes. This drug can interact with other medications, such as Adderall, oral birth control, and certain supplements.

Mounjaro is prescribed along with exercise and a balanced diet to help manage blood sugar levels in adults with type 2 diabetes.

An interaction can occur because one substance causes another substance to have a different effect than expected. Interactions can also occur if you have certain health conditions.

Keep reading to learn about Mounjaro’s possible interactions. And for more information about Mounjaro, including details about its uses, see this article.

There are no known interactions between Mounjaro and alcohol. But alcohol and Mounjaro may cause similar side effects. These can include:

  • nausea
  • vomiting
  • diarrhea

Drinking alcohol during your Mounjaro treatment may raise your risk for these side effects or make them worse if you experience them.

Also, alcohol can raise your risk of low blood sugar if you have type 2 diabetes (which Mounjaro is used to treat). Mounjaro can also cause low blood sugar. So drinking alcohol during your Mounjaro treatment may further raise your risk of low blood sugar.

If you drink alcohol, talk with your doctor about how much (if any) is safe to consume during your Mounjaro treatment.

Certain health conditions or other factors could raise your risk of harm if you take Mounjaro. In such cases, your doctor may not prescribe Mounjaro for you. These are known as contraindications. The list below includes contraindications of Mounjaro.

If you or a family member has had medullary thyroid cancer (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2). Mounjaro may increase the risk of thyroid cancer. The drug has a boxed warning for this side effect.

If you or a family member has had MTC or MEN 2, your risk of thyroid cancer with Mounjaro may be higher. Due to this risk, doctors will not prescribe Mounjaro if you or a family member has had MTC.

If you’ve had an allergic reaction. If you’ve had an allergic reaction to Mounjaro or any of its ingredients, your doctor will not prescribe Mounjaro. This is because taking the drug could cause another allergic reaction. You can ask your doctor about other treatments that may be better options for you.

Before you start Mounjaro treatment, talk with your doctor if any of the factors above apply to you. Your doctor can determine whether Mounjaro is safe for you to take.

Before you start taking Mounjaro, tell your doctor and pharmacist about any prescription, over-the-counter, or other drugs you take. Sharing this information with them may help prevent possible interactions. (To learn whether Mounjaro interacts with supplements, herbs, and vitamins, see the “Are there other interactions with Mounjaro?” section below.)

If you have questions about drug interactions that may affect you, talk with your doctor or pharmacist.

Learn more about certain drug interactions that can occur with Mounjaro.

Interaction with birth control pills

Mounjaro can interact with birth control pills.

Examples of birth control pills include:

  • ethinyl estradiol/norethindrone (Junel)
  • ethinyl estradiol/norgestimate (Tri-Sprintec)
  • ethinyl estradiol/drospirenone (Yasmin)
  • ethinyl estradiol/norgestimate (Estarylla)
  • ethinyl estradiol/norgestimate (TriNessa)

What could happen

Mounjaro makes your stomach empty its contents more slowly. This may affect how your body absorbs drugs that you swallow, including birth control pills. This could make birth control pills less effective.

What you can do

If you take birth control pills, tell your doctor before starting Mounjaro treatment. They’ll likely recommend that you switch to a different method of birth control.

Examples of these other birth control methods include:

  • medroxyprogesterone (Depo-Provera) injection
  • copper intrauterine device (IUD) (Paragard)
  • etonogestrel and ethinyl estradiol (NuvaRing) vaginal ring
  • norelgestromin and ethinyl estradiol (Xulane) patch

If switching birth control methods isn’t an option (or you prefer not to), your doctor may recommend that you use a barrier method of contraception, such as a condom, along with your birth control pills. You may need to do this for 4 weeks after starting Mounjaro and for 4 weeks after any dosage increases during your treatment.

Interaction with amphetamine/dextroamphetamine (Adderall, Adderall XR)

Mounjaro can interact with amphetamine/dextroamphetamine (Adderall, Adderall XR) and other medications that you swallow.

What could happen

Mounjaro makes your stomach empty its contents more slowly. This may affect how your body absorbs drugs that you swallow, including Adderall. So it may take longer than usual for Adderall to start working if you take it with Mounjaro.

Also, stimulants, such as Adderall, can raise your blood sugar level. Mounjaro works to lower your blood sugar level. So taking Adderall with Mounjaro may make it harder to manage your blood sugar.

What you can do

If you take Adderall, talk with your doctor before starting Mounjaro treatment. They can adjust your Adderall dosage schedule if needed so that the drug is safe to take with Mounjaro.

Your doctor may also recommend that you check your blood sugar more often while taking these medications together.

Interaction with insulin

Mounjaro may interact with insulin.

In some cases, doctors may prescribe Mounjaro with insulin to help manage blood sugar levels in people with type 2 diabetes.

Examples of insulin medications include:

What could happen

One way Mounjaro helps lower your blood sugar is by helping your body release insulin. Insulin helps move sugar from your blood into your cells so your body can use it for energy.

Taking Mounjaro with insulin may cause you to have too much insulin in your body. This can lead to low blood sugar.

What you can do

If your doctor prescribes Mounjaro along with insulin, they’ll likely lower your insulin dosage. They’ll also recommend you monitor your blood sugar levels more closely while taking these medications together.

It’s important to know the signs of low blood sugar while you’re using Mounjaro. These can include:

  • dizziness
  • shakiness
  • fast heart rate
  • headache
  • sweating
  • trouble concentrating
  • hunger

Keep in mind that hypoglycemia can become serious and may be life threatening if not treated right away. If you experience symptoms of low blood sugar, eat or drink something that contains carbohydrates. This can help raise your blood sugar level quickly.

Find answers to some frequently asked questions about Mounjaro and possible interactions.

Does Mounjaro interact with nicotine patches?

No, Mounjaro should not interact with nicotine patches, such as NicoDerm CQ or Habitrol. (Nicotine patches are used to help quit smoking.)

Mounjaro makes your stomach empty its contents more slowly. This may affect how your body absorbs drugs that you swallow. But the medication in nicotine patches is absorbed through your skin and does not go through your stomach. Because of this, Mounjaro does not affect how nicotine patches work.

But keep in mind that Mounjaro can interact with medications taken by mouth that help you quit smoking, such as bupropion. It may take longer for your body to absorb these drugs and for them to start working.

If you have questions about how Mounjaro may affect your other medications, talk with your doctor or pharmacist.

Is there an interaction between Mounjaro and albuterol inhaler?

No, there are no known interactions between Mounjaro and albuterol inhalers (Ventolin HFA, Proventil HFA). But it’s important to note that Mounjaro may interact with other forms of albuterol, including the tablets and syrup.
