Zenegra 100 mg contains sildenafil citrate, a well-known PDE-5 inhibitor used to treat erectile dysfunction (ED) in men. By enhancing blood circulation to the penis during sexual arousal, it helps achieve and sustain an erection. According to the Mayo Clinic, sildenafil has been clinically tested and proven effective for ED treatment, while Drugs.com provides complete drug monographs for safe use.

Key Benefits & Uses

• Effective in treating erectile dysfunction, even in men with underlying conditions.

• Onset within 30–60 minutes, lasting up to 4 hours (WebMD).

• May also be used off-label for pulmonary hypertension, supported by research available on PubMed.

• Recognized by the World Health Organization as an essential medicine, ensuring its global medical importance.

How to Use

Take one tablet 30–60 minutes before sexual activity with water. It works best on an empty stomach, as heavy meals delay absorption (Healthline). Do not take more than one dose per day, as recommended by the FDA. Sexual stimulation is necessary for the medicine to work.

Important Safety Information

Zenegra 100 mg should not be combined with nitrates or medications like riociguat, as this may lead to dangerous drops in blood pressure (Mayo Clinic). Patients with heart problems, recent stroke, or severe kidney/liver conditions must consult a doctor first. The FDA warns against unsupervised use, and resources such as Drugs.com list important interactions.

Common Side Effects

Some users may experience headache, flushing, upset stomach, nasal congestion, or dizziness (WebMD). Less common effects include blurred or tinted vision, ringing in the ears, or muscle aches. Rare but serious side effects include priapism (prolonged erection), sudden hearing loss, or vision problems—cases documented in PubMed. If any severe reaction occurs, immediate medical care is required.
