Tadalista 10 mg is not available over the counter in India or most countries. It is a prescription-only medicine, meaning you are supposed to get it only after a doctor’s evaluation. Why it is not OTC Tadalafil affects blood vessels and blood pressure, so doctors need to check: Heart conditions (risk of low blood pressure) Blood pressure medicines or nitrates (dangerous interaction) Liver/kidney health Other ED treatments already being used What this means in practice You generally need a prescription from a registered doctor Pharmacies may still sometimes dispense it without strict checking, but that is not legal OTC status Online pharmacies also usually mark it as “prescription required” Important note Even though Tadalista 10 is a lower dose of tadalafil, it is still a systemic cardiovascular drug, not a casual supplement. If you want, I can explain: whether 10 mg is a low/medium/high dose or how it compares with 5 mg daily vs 20 mg as-needed use
