Filagra is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil citrate, the same active ingredient found in Viagra, and works by increasing blood flow to the penis during sexual arousal. By inhibiting the enzyme phosphodiesterase type 5 (PDE5), Filagra helps relax the blood vessels in the penis, facilitating the ability to achieve and maintain a firm erection.

Filagra is typically available in dosages of 50mg or 100mg and should be taken approximately 30-60 minutes before sexual activity. The effects of Filagra can last for up to 4-6 hours, providing a window for sexual activity. However, it is important not to exceed one dose per day.

Common side effects may include headaches, flushing, dizziness, nasal congestion, and indigestion. Although rare, serious side effects such as priapism (a prolonged, painful erection), sudden vision loss, or hearing loss may occur, requiring immediate medical attention.
