Zenegra is a generic medication used to treat erectile dysfunction (ED). It is a brand name for sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. It is used to relax the blood vessels in the penis and increase blood flow, which helps men achieve and maintain an erection.
Zenegra contains the active ingredient sildenafil citrate, as well as inactive ingredients such as microcrystalline cellulose, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose monohydrate, triacetin, and FD&C Blue #2 aluminum lake.
Sildenafil citrate is also known by its brand name Viagra, and is also available in other generic versions such as Suhagra, Silagra, and Kamagra.
The recommended starting dose of Zenegra is 50 mg, taken one hour before sexual activity. The maximum recommended dose is 100 mg. The dose may be increased or decreased depending on response and tolerability.
Common side effects of Zenegra include headache, flushing, upset stomach, runny nose, blurred vision, and dizziness. If any of these side effects persist or worsen, contact your doctor.
Serious side effects may include a sudden decrease or loss of vision, hearing, or ringing in the ears. If any of these serious side effects occur, seek medical attention immediately.
Before taking Zenegra, tell your doctor if you have any allergies, heart disease, high or low blood pressure, kidney or liver disease, a blood cell disorder, a stomach ulcer, or retinitis pigmentosa.
It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not take Zenegra with any other medications, including nitrates.
