The manufacturer of Arexvy didn’t look at interactions with other medications in the vaccine’s clinical trials. However, it’s possible that new interactions may be recognized in the future. For example, people who’ve received Arexvy since it became available could report a suspected interaction.

Before you receive Arexvy, tell your doctor and pharmacist which prescription, over-the-counter, and other medications you take. By sharing this information with them, you may help prevent possible interactions. (To learn whether Arexvy interacts with supplements, herbs, or vitamins, see the “Arexvy and other interactions” section below.)

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

In some cases, factors or conditions could prevent your doctor from prescribing Arexvy due to the risk of harm. These are known as contraindications. One contraindication of Arexvy is:

Having had an allergic reaction to Arexvy or any of its ingredients

Arexvy is a vaccine given to help prevent lower respiratory infections from RSV. If you’ve ever had an allergic reaction to Arexvy or any of its ingredients, your doctor will likely not prescribe Arexvy. Receiving Arexvy could cause another allergic reaction. You can ask them about other vaccines that may be better choices for you.

Note: Before you receive Arexvy, it’s important to tell your doctor if this contraindication applies to you. They can determine whether to prescribe Arexvy.

There are no known interactions between Arexvy and alcohol.

If you have questions about drinking alcohol before or after receiving Arexvy, talk with your doctor or pharmacist.

AREXVY AND CANNABIS OR CBD

Cannabis (often called marijuana) and cannabis products, such as cannabidiol (CBD), have not been specifically reported to interact with Arexvy. However, as with any vaccine, talk with your doctor before using cannabis in combination with Arexvy.

Certain medical conditions and other factors may increase the risk of interactions with Arexvy. Before you receive this vaccine, be sure to talk with your doctor about your health history. Arexvy may not be the right vaccine option if you have certain medical conditions or other factors affecting your health.

Health conditions or factors that might interact with Arexvy include:

  • Weakened immune system: If you have a weakened immune system, Arexvy may not work as well at helping to prevent lower respiratory infections from RSV. Before receiving Arexvy, tell your doctor if you have a weakened immune system. They’ll determine whether Arexvy is right for you.
  • Allergic reaction: If you’ve ever had an allergic reaction to Arexvy or any of its ingredients, your doctor will likely not prescribe Arexvy. Receiving the vaccine could cause another allergic reaction. You can ask them about other vaccines that may be better choices for you.
  • Breastfeeding: It’s not known whether receiving Arexvy while breastfeeding is safe. There isn’t enough information to determine whether the vaccine passes into breast milk or what effects Arexvy may have on a child who is breastfed. (It’s also important to note this vaccine isn’t approved for people younger than age 60 years.) If you’re breastfeeding or planning to, talk with your doctor before receiving Arexvy.
  • Pregnancy: There haven’t been enough clinical trials to determine whether Arexvy is safe to receive during pregnancy. This vaccine isn’t approved for people younger than age 60 years. If you’re pregnant or planning to become pregnant, tell your doctor before receiving Arexvy.

You can take certain steps to help prevent interactions with Arexvy. Your doctor and pharmacist are key resources, so reach out to them before you get the vaccine. For example, you should plan to do the following:

  • Let them know if you drink alcohol or use cannabis.
  • Tell them about any other medications you take, as well as any supplements, herbs, and vitamins.
  • Create a medication list, which your doctor and pharmacist can help you fill out.

It’s also important to read the Arexvy label and other paperwork that may come with the vaccine. The label may have colored stickers that mention an interaction. And the paperwork, sometimes called the medication guide or patient package insert, may contain details about interactions.

If Arexvy doesn’t come with paperwork, you can ask your pharmacist to print a copy. If you need help reading or understanding this information, ask your doctor or pharmacist.
