Verquvo (vericiguat) is a brand-name oral tablet that’s prescribed for reducing certain risks in people with chronic heart failure. Verquvo has interactions with some other drugs. Examples include sildenafil (Viagra) and tadalafil (Cialis).

Verquvo is prescribed for reducing the risk of hospitalization and death in certain adults with chronic heart failure with reduced ejection fraction.

An interaction occurs when one substance causes another substance to have a different effect than expected.

To learn more about Verquvo’s interactions, keep reading. For additional information about Verquvo, including details about its uses, see this article.

Before you start treatment with Verquvo, 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 Verquvo interacts with supplements, herbs, or vitamins, see the “Verquvo and other interactions” section below.)

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

Here’s a table of drugs that can interact with Verquvo. Keep in mind that this table doesn’t include all drugs that may interact with Verquvo. Some of these interactions are described in detail just below in “Drug interactions in depth.”

Drug class or drug nameDrug examplesInteraction result with Verquvo
other guanylate cyclase stimulators• riociguat (Adempas)can cause low blood pressure
phosphodiesterase-5 inhibitors• avanafil (Stendra)
• sildenafil (Viagra, Revatio)
• tadalafil (Cialis, Adcirca)
• vardenafil
can cause low blood pressure

In some cases, factors or conditions could prevent your doctor from prescribing Verquvo due to the risk of harm. These are known as contraindications. The contraindications of Verquvo include:

Taking another guanylate cyclase stimulator

Verquvo belongs to a class of drugs called guanylate cyclase stimulators. Doctors typically will not prescribe Verquvo in combination with other drugs from this class. Examples include riociguat (Adempas), which is used to treat pulmonary hypertension (high blood pressure in the artery that carries blood from your heart to your lungs).

Taking Verquvo with another guanylate cyclase stimulator can cause low blood pressure.

If you take a medication of this type, talk with your doctor about your treatment options.

Are pregnant or may become pregnant

Doctors typically won’t prescribe Verquvo during pregnancy. They’re also unlikely to prescribe the drug for this use if you’re able to become pregnant and not using effective birth control.

This is because Verquvo may not be safe to take during pregnancy. In fact, the drug has a boxed warning about the risk of fetal harm. A boxed warning is the most serious warning from the FDA. For details, see “Boxed warning” at the beginning of this article.

For treatment of heart failure during pregnancy, your doctor can recommend a different treatment that’s safe for use in pregnancy. If you’re able to become pregnant, your doctor can advise you on birth control options to use while taking Verquvo for heart failure.

Note: Before you start treatment with Verquvo, it’s important to tell your doctor if these contraindications apply to you. They can determine whether to prescribe Verquvo.

There aren’t any known interactions between Verquvo and alcohol. However, your doctor may advise you to avoid or limit alcohol consumption during Verquvo treatment.

This is because Verquvo can cause low blood pressure, which could make you feel dizzy. Drinking alcohol while taking the drug may raise your risk of this side effect.

If you have questions about drinking alcohol while taking Verquvo, talk with your doctor.

Here’s a closer look at certain drug interactions of Verquvo.

Phosphodiesterase-5 inhibitors

Verquvo can interact with phosphodiesterase-5 (PDE5) inhibitors. Drugs from this class are prescribed to treat erectile dysfunction and pulmonary hypertension (high blood pressure in the artery that carries blood from your heart to your lungs).

Interaction result: Taking Verquvo with a PDE5 inhibitor can cause low blood pressure.

Interaction explained: Verquvo and PDE5 inhibitors can both cause low blood pressure. So taking them together can raise your risk of this side effect.

Examples of PDE5 inhibitor drugs: Here are some PDE5 inhibitors that may interact with Verquvo:

  • avanafil (Stendra)
  • sildenafil (Viagra, Revatio)
  • tadalafil (Cialis, Adcirca)
  • vardenafil

Steps you or your doctor may take: Your doctor will likely avoid prescribing Verquvo with a PDE5 inhibitor. You can talk with them about other treatment options for your condition.

  • Create a medication list, which your doctor and pharmacist can help you fill out.
