Filitra 20 mg is a medication marketed for erectile dysfunction (ED) in men. It typically contains vardenafil 20 mg, a PDE5 inhibitor that improves blood flow to the penis during sexual stimulation. Filitra is generally taken about 30–60 minutes before sexual activity, following medical advice. For vardenafil, 20 mg is the usual maximum recommended single dose for many adults. Do not take more than one dose in 24 hours unless specifically instructed by your healthcare professional.
