If Vidalista 5 mg is tadalafil, the usual dosing rule is once daily. You should generally leave at least 24 hours between doses unless your doctor has specifically prescribed a different schedule. Do not take extra doses if the first dose seems ineffective. Tadalafil can remain in the body for Vidalista 5 mg than 2 days, so taking additional doses too soon can increase side effects. Avoid combining it with other tadalafil-containing products or other PDE-5 inhibitors unless a clinician tells you to. If you're taking tadalafil daily, take it at approximately the same time each day. If you've already taken 5 mg and are considering another dose today, tell me what time you took the first dose and why you want to take another, and I can help you assess the situation.
