Drug Interactions With Sildenafil Medication

Sildenafil, also known as Viagra, is a medication commonly used to treat erectile dysfunction. It works by increasing blood flow to the penis, making it easier to get and maintain an erection. While sildenafil is generally safe and effective, it can interact with other medications, leading to potential side effects or decreased effectiveness.  

Common Drug Interactions with Sildenafil

• Nitrates: Nitrates are medications used to treat angina (chest pain). They work by relaxing blood vessels, which can lower blood pressure. Sildenafil can also lower blood pressure, so taking the two medications together can cause a dangerous drop in blood pressure.
• Alpha-blockers: Alpha-blockers are medications used to treat high blood pressure and enlarged prostate. They can also lower blood pressure, so taking them with sildenafil can increase the risk of low blood pressure.
• Azole antifungals: Azole antifungals are medications used to treat fungal infections. They can increase the levels of sildenafil in the blood, which can increase the risk of side effects.
• Protease inhibitors: Protease inhibitors are medications used to treat HIV. They can increase the levels of sildenafil in the blood, which can increase the risk of side effects.
• Macrolide antibiotics: Macrolide antibiotics are medications used to treat bacterial infections. They can increase the levels of sildenafil in the blood, which can increase the risk of side effects.

Other Medications to Avoid with Sildenafil

In addition to the medications listed above, there are other medications that can interact with sildenafil. These include:

• Cimetidine: Cimetidine is a medication used to treat heartburn and ulcers. It can increase the levels of sildenafil in the blood, which can increase the risk of side effects.
• Erythromycin: Erythromycin is an antibiotic. It can increase the levels of sildenafil in the blood, which can increase the risk of side effects.
• Grapefruit juice: Grapefruit juice can increase the levels of sildenafil in the blood, which can increase the risk of side effects.

What to Do if You Are Taking Sildenafil

It is also important to tell your doctor if you experience any side effects while taking sildenafil. Side effects can include headache, flushing, and upset stomach.
