Additional Details
What is Penegra 100mg used for?
Penegra 100mg is prescribed for erectile dysfunction (ED) in adult men. ED is the inability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It is one of the most common medical conditions in Pakistan and affects men of all ages, though prevalence increases with age, diabetes, cardiovascular disease, and psychological factors.
Sildenafil (the active ingredient in Penegra) is clinically effective in:
- Vascular ED (reduced arterial blood flow to the penis)
- Diabetic ED (nerve and vessel damage from diabetes)
- Post-prostatectomy ED (following prostate surgery)
- Psychogenic ED (anxiety, stress, or performance pressure)
- Mixed-cause ED (both physical and psychological factors)
Dosage and how to take Penegra 100mg
- Take one tablet 30 to 60 minutes before sexual activity
- Swallow whole with a glass of water — do not crush or split
- Can be taken with or without food; high-fat meals may slow onset
- Maximum one tablet in any 24-hour period
- Works only with sexual stimulation — does not cause spontaneous erections
- Consult your doctor before use, especially if you have heart conditions
Side effects
Common (similar to all sildenafil medicines): headache, flushing, nasal congestion, indigestion, and dizziness. Serious but rare: sudden vision or hearing changes, chest pain, or erections lasting longer than 4 hours (priapism — seek immediate medical help).

WARNING: Do not take Penegra if you use nitrate medicines for chest pain or heart disease. The combination causes a life-threatening drop in blood pressure.

Penegra 100mg vs Viagra 100mg — understanding the difference
Penegra and Viagra share the identical active ingredient: sildenafil citrate 100mg. Both are PDE5 inhibitors that work by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. The clinical mechanism, effectiveness, onset time (30–60 minutes), and duration (4–6 hours) are the same.
The difference lies in the manufacturer and price. Viagra is produced by Pfizer (USA), the original patent holder. Penegra is produced by Zydus Healthcare (India), a manufacturer with WHO-GMP certification and a strong track record in producing high-quality generic medicines. For many men with erectile dysfunction in Pakistan, Penegra provides an equally effective, more affordable treatment option.
