When being prescribed as a treatment for ED, sildenafil’s effects typically last around four hours.

If you’re looking for an ED medication with longer-lasting effects, you may want to explore alternative options like Cialis (tadalafil).

Sildenafil (generic Viagra) may not be safe for people with certain heart conditions, low blood pressure, or those taking nitrate medications. Adults over 65 or those with existing liver or kidney conditions are at higher risk of side effects from the medication. Your Sesame provider will review your medical history to ensure the medication is safe for you.

For concerns related to sex drive or libido, your provider may recommend other approaches.

Avoid taking sildenafil (generic Viagra) with nitrates, which are commonly prescribed for chest pain. You should also avoid certain blood pressure medications, such as doxazosin or [terazosin] (https://sesamecare.com/medication/terazosin), as these can cause a dangerous drop in blood pressure.

Limit or avoid excessive alcohol. Talk to your doctor before combining sildenafil with other medications or supplements.

Taking more sildenafil (generic Viagra) than prescribed can increase the risk of side effects such as headaches, dizziness, changes in blood pressure, or a prolonged and painful erection.

If you suspect that you’ve taken too much sildenafil or are experiencing any serious side effects, call your healthcare provider or seek emergency care immediately.

Sildenafil (including Viagra) is currently only available by prescription and cannot be purchased over the counter (OTC). A licensed healthcare provider must authorize its use to ensure it is safe and appropriate for you.

Providers on Sesame can write a new prescription or refill an existing one during a virtual or in-person visit, with options for same-day pharmacy pickup when available. All prescriptions are written at the provider’s discretion.
