Edit list (add/remove drugs)

Interactions between your drugs

Moderate

yohimbine sildenafil

Applies to: yohimbine and Viagra (sildenafil)

Using yohimbine and sildenafil together may lead to increased side effects, such as low blood pressure, dizziness, fainting, and/or priapism (prolonged and painful erection unrelated to sexual activity). Your doctor may already be aware of the risks but has determined that this is the best course of treatment for you, has taken appropriate precautions, and is monitoring you closely for any potential complications. Seek immediate medical attention if you experience an erection that lasts for more than 4 hours. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food/lifestyle interactions

Moderate

sildenafil food/lifestyle

Applies to: Viagra (sildenafil)

If you are receiving therapy with sildenafil you should avoid the regular consumption of large amounts of grapefruits and grapefruit juice. Grapefruit can raise the levels of sildenafil in your body and delay the time it takes for the medication to work. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
