Fildena is available in various strengths, such as 25 mg, 50 mg, 100 mg, and even up to 150 mg and Super Active forms, allowing doctors to tailor the dosage to individual needs. It is typically taken 30 to 60 minutes before sexual activity, and its effects can last for up to 4 to 6 hours. However, it does not cause an erection without sexual arousal. Common side effects include headache, flushing, nasal congestion, dizziness, upset stomach, and visual disturbances.
