Frequently asked questions about sildenafil
How long does sildenafil take to work?
Like branded Viagra, sildenafil (generic of Viagra) can start working in 30–60 minutes, when used as directed. Sexual arousal is still required for the medication to work.
How long does sildenafil last?
Sildenafil can help support erections for up to 4–6 hours, though timing can vary from person to person.
How do you get sildenafil on Ro?
Complete a convenient online visit about your health and ED symptoms. A Ro-affiliated licensed healthcare provider will assess your information and, if appropriate, prescribe sildenafil (generic of Viagra) or another ED treatment. If prescribed, your medication ships in discreet packaging at no extra cost.
What are the available sildenafil dosages on Ro?
Sildenafil is available in 25 mg, 50 mg, and 100 mg doses. Your provider will recommend the dose that’s right for you based on your health history, symptoms, and treatment goals.
How do you take sildenafil?
Take sildenafil 30–60 minutes before sex as directed by your provider. Sildenafil works best when taken on an empty stomach, since high-fat meals can delay its effects.

What safety information should I know before taking Viagra?
