Tadalista 10 mg requires a prescription, the answer depends on the country and the specific product. Tadalafil is a prescription medicine in the U.S.; official labeling identifies it as a “HUMAN PRESCRIPTION DRUG.” 10 mg is the standard starting dose for tadalafil taken as needed for ED; it can be adjusted to 5 or 20 mg based on effectiveness and tolerability, generally no more than once daily. In India, the exact legal dispensing requirements can depend on the formulation, manufacturer, and applicable state/drug-control rules, so a registered medical practitioner’s prescription is the safest approach. Because you've been asking about tadalafil following prostate surgery, it's particularly sensible to have a doctor review your other medicines and cardiovascular status before using it.
