What it is
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. A licensed DrWell provider may prescribe it for erectile dysfunction (ED) as part of a sexual wellness program after reviewing your symptoms, medications and health history.
The brand-name version of sildenafil, Viagra, is FDA approved. The sildenafil offered here is compounded. It is prepared by a licensed pharmacy for an individual patient based on a prescription. Compounded medications are not FDA approved, which means the FDA has not evaluated their safety, effectiveness or quality.
How it works
Sildenafil blocks an enzyme called PDE5. Blocking it helps blood vessels relax and widen, which increases blood flow. It works in response to sexual stimulation and does not cause arousal on its own.
Your provider determines the dose and how it should be used, and may adjust it based on how you respond.
What to expect
Your provider will review your health history, blood pressure and every medication you take before prescribing. Your provider will tell you how much to use and when, and may change the plan over time.
Individual responses vary, and results are not guaranteed.
Who it is for
Whether sildenafil is appropriate for you is a decision made by a licensed provider based on your symptoms, examination and health history. It is not appropriate for everyone, including people who take nitrate medications and people with certain heart conditions.
Sexual health concerns can have many causes, including heart health, diabetes, hormone levels and medications. Your provider will evaluate the full picture.
