What you don’t know about Viagra can hurt you. Learn which drugs interact with Viagra to protect your health.
That’s because Viagra belongs to a powerful class of drugs used to treat male impotence. Like all medications, the interactions between different types of drugs can cause unpleasant or dangerous side effects. This article will give you a brief overview of the drugs to watch out for if you’re talking Viagra for male impotence.
Drug Interactions and Viagra
Livestrong points out that Viagra is metabolized in the bloodstream and broken down in the liver, which increases the risk of drug interactions. Viagra has known negative drug interactions with:
- The nitrate classes of drugs typically prescribed for chest pain and heart disease. These drugs dilate the blood vessels, working in a similar way to male impotence drugs. Together with Viagra, these medications can cause a dangerous drop in blood pressure. Symptoms include dizziness, fainting, heart attack, or stroke.
- Macrolide antibiotics treat all kinds of infections. But these medications prevent Viagra from breaking down in the blood. While you can still take Viagra for male impotence, you must take no more than 25mg daily – or avoid it altogether until the antibiotic is done.
- The protease inhibitors used to treat HIV. Protease inhibitors combined with Viagra can cause an erection last four hours or longer, chest pain, or unconsciousness.
While these classes of drugs cause the most dangerous interactions, WebMD also lists a “severe interactions” cautionary list including nitrates, other PDE inhibitors, and mifepristone.
Using Viagra to treat male impotence is generally safe, but always consult your physician to prevent any dangerous drug interactions.
