Osyvega: A Brand of Sildenafil for Erectile Dysfunction

What it is

Osyvega is a brand of sildenafil citrate. Sildenafil belongs to a class of medicines called phosphodiesterase-5 (PDE5) inhibitors, which help increase blood flow to the penis to treat erectile dysfunction.

What it's used for

Osyvega (sildenafil) is used for the treatment of erectile dysfunction in men. It helps achieve and maintain an erection when sexually stimulated.

How it's taken

Osyvega is taken as a tablet by mouth. The dose is typically taken about one hour before sexual activity, though it can be taken 30 minutes to 4 hours before. The usual dose is 50 mg, but your doctor may adjust it between 25 mg and 100 mg based on how well it works and how you tolerate it. Do not take more than one dose in a day. Always follow your doctor's or pharmacist's instructions.

Common side effects

Common side effects may include headache, flushing, indigestion, nasal congestion, dizziness, and visual disturbances such as a blue tinge to vision. More serious side effects include prolonged erection lasting over 4 hours (priapism), sudden vision loss in one or both eyes, hearing loss, and low blood pressure when taken with certain medicines.

Important cautions

Do not take Osyvega if you are using nitrates (often prescribed for chest pain) or guanylate cyclase stimulators (such as riociguat). If you have a heart condition that makes sexual activity risky, consult your doctor first. Seek emergency medical help if an erection lasts more than 4 hours, or if you experience sudden vision or hearing loss. Use caution if you take alpha-blockers or blood pressure medicines.
