Vidalista, the versions used for erectile dysfunction (ED) contain tadalafil. Vidalista 5 mg — lower-dose tadalafil; sometimes used daily. Vidalista 10 mg — common starting strength for as-needed use. Vidalista higher as-needed dose, generally used when 10 mg isn't effective/tolerated. Vidalista 40 mg — unusually high for ED and should not be taken without medical supervision. Tadalafil can work for up to 36 hours, but it doesn't cause an erection without sexual stimulation. If you tell me your age and whether you're currently taking any medicines (especially heart/blood-pressure medicines), I can explain which tadalafil dose is typically appropriate and what to avoid.
