Tadalista 40 (tadalafil 40 mg) is a prescription-only medicine in India and most countries. Why: It contains tadalafil, which is a PDE-5 inhibitor used for erectile dysfunction (ED). In India, tadalafil falls under Schedule H of the Drugs and Cosmetics Rules. Schedule H medicines can only be sold by a licensed pharmacy with a valid doctor’s prescription. What this means in practice: You are supposed to get it after a doctor’s consultation. Pharmacies should ask for a prescription before dispensing it. Selling it without prescription is technically illegal, even though it sometimes happens in informal or online markets. Important note: Tadalista 40 is a high dose (40 mg), which is stronger than the commonly used 10–20 mg doses. It can increase the risk of side effects like: headache low blood pressure dizziness heart-related strain (in some people) So it’s especially important that a doctor decides if this dose is appropriate. If you want, I can explain: whether 40 mg is safe compared to 20 mg how long it lasts or how to use tadalafil safely with fewer side effects
