Vidalista 2.5 is typically prescribed for individuals who require a mild potency of tadalafil or for those who are taking it daily for the treatment of ED. It is often used in a daily regimen, where a low dose of tadalafil is taken regularly regardless of sexual activity. Tadalafil, the active ingredient in Vidalista 2.5, works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection.
