Vidalista 20 mg includes tadalafil, a PDE5 inhibitor used to treat erectile dysfunction. Tadalafil works by boosting blood flow to the penis during sexual stimulation, allowing men to attain and maintain erections. Tadalafil has been shown in clinical studies to be an effective ED treatment, with benefits lasting up to 36 hours.

Vidalista 20 may be safe when used as directed, but it is not appropriate for everyone. Common adverse effects may include headache, indigestion, back pain, flushing, and nasal congestion.
