Vidalista 5 mg should not be taken without a prescription. It is a prescription medication containing Tadalafil, which affects blood vessels, blood pressure, and heart function. Using it without medical guidance can be risky. Why a Prescription Is Needed Medical assessment: A doctor evaluates if you have conditions (heart disease, low/high blood pressure, liver or kidney problems) that make Tadalafil unsafe. Drug interactions: Vidalista 5 mg can interact dangerously with nitrates, certain blood pressure medications, or other drugs. Proper dosing: Even 5 mg can cause side effects if taken inappropriately. Doctors may adjust the dose based on age, health, and ED severity. Side effect management: Common side effects include headache, flushing, dizziness, indigestion, or back pain. Rare but serious effects like prolonged erections (priapism), sudden vision or hearing loss, or chest pain require medical supervision. Safe Use Always take Vidalista only under a doctor’s prescription. Follow the prescribed dose and schedule — usually once daily for the 5 mg version. Report any unusual symptoms to a healthcare professional immediately. Taking it without guidance increases the risk of serious complications, even at low doses.
