Vidalista (tadalafil) can be dangerous and may lead to serious side effects. Here’s what can happen and what you should do: 1. Common Side Effects of Overdose Headache Flushing (redness of face/neck) Dizziness or light-headedness Nasal congestion Indigestion These symptoms are more intense than usual if you take more than the prescribed dose. 2. Serious Risks Low blood pressure: Tadalafil can cause a dangerous drop in blood pressure, especially if combined with nitrates or certain heart medications. Prolonged erection (priapism): An erection lasting more than 4 hours can cause permanent tissue damage. Heart problems: Chest pain, irregular heartbeat, or heart attack in susceptible individuals. Vision or hearing changes: Sudden loss of vision or hearing is rare but possible. 3. What to Do Do not take any more tablets. Seek immediate medical attention if you experience severe dizziness, chest pain, erection lasting >4 hours, or vision/hearing problems. Contact poison control if unsure about the dose taken. 4. Prevention Stick to the prescribed dose (usually 5–20 mg once daily for ED). Avoid combining with other PDE5 inhibitors. Discuss with a doctor if you feel the medication isn’t effective instead of increasing the dose on your own.
