Sildenafil

Sildenafil is the active ingredient in the brand-name medication Viagra^®. Sildenafil works the same way as Viagra and has the same benefits and risks, according to the FDA. 

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, an oral medication used to treat erectile dysfunction (ED) by increasing blood flow to the penis. It is taken only as needed, usually about an hour before sexual activity, though it can be effective if taken between 30 minutes to four hours prior. 

It is very important not to take Viagra more than once a day, as exceeding this frequency increases the risk of serious side effects, including vision loss and significant drops in blood pressure.

Viagra (sildenafil citrate) is indicated to treat:

• Erectile dysfunction (ED)

Phosphodiesterase-5 (PDE5) inhibitor

Most common adverse reactions (≥2%) include:

• Headache

• Flushing

• Indigestion

• Abnormal vision

• Nasal congestion

• Back pain

• Muscle pain

• Rash

The cost of sildenafil may vary depending on factors such as your insurance plan, the dosage, the quantity, and where you buy it.

Without insurance, the average retail price of sildenafil is about $23 per tablet, but coupons and discount cards may bring the cost to less than $1 per tablet. Insurance may cover all or some of the cost of the drug.

Hims offers access to sildenafil starting at $4 per use after a thorough medical consultation.  Based on your symptoms and medical history, a healthcare provider will determine if the product is a good fit for your needs.
