Tadalista 10 mg contains Tadalafil, which is a prescription-only medicine in India. In India, tadalafil-based medicines are classified under Schedule H drugs, meaning they must be sold only with a valid doctor’s prescription from a registered medical practitioner. You should not legally get it over the counter without one. Why a prescription is required Doctors usually prescribe it because: It affects blood pressure and blood flow It may interact dangerously with medicines like nitrates (used for chest pain) It is not safe for everyone, especially people with heart disease, liver/kidney problems, or uncontrolled BP The correct dose depends on your health condition and response Important note Even though some pharmacies may sometimes sell it without asking (which happens in practice), it is still not considered safe or proper medical use without medical guidance. If you want, I can also explain the difference between 5 mg, 10 mg, and 20 mg doses and when each is usually prescribed.
