Filitra is available in several strengths, including 10 mg and 20 mg, with the 20 mg dose being the most commonly prescribed for ED treatment. The recommended dose for Filitra is typically 10 mg, taken about 30–60 minutes before sexual activity. The effects can last up to 4–5 hours, providing flexibility for spontaneous sexual encounters. Common side effects include headache, dizziness, flushing, nasal congestion, and mild digestive discomfort. In rare cases, more serious side effects like prolonged erections (priapism), sudden vision or hearing changes, or heart-related issues may occur, requiring immediate medical attention. https://www.genericday.com/filitra-20-mg.html
