Fildena Professional is designed for fast absorption, allowing it to start working more quickly than standard sildenafil tablets, often within 20–30 minutes. This makes it particularly useful for men who prefer rapid onset of action. The effects typically last for about 4–6 hours, giving sufficient time for sexual activity. Common side effects include headache, flushing, dizziness, nasal congestion, and mild stomach upset. Rare but serious side effects—such as prolonged erections (priapism), chest pain, fainting, or sudden changes in vision or hearing—require immediate medical attention.
