Vilitra 20 contains vardenafil 20 mg, and Vilitra is marketed in other strengths as well. Current listings from the manufacturer show 10 mg, 20 mg, and higher-strength variants, although the higher strengths are above the standard recommended vardenafil dose. C Centurion Laboratories +1 For medically established vardenafil dosing, the standard strengths are 5 mg, 10 mg, and 20 mg, with 20 mg being the maximum recommended dose once per day. E European Medicines Agency (EMA) +1 So, in practical terms: 5 mg — lower dose 10 mg — usual starting dose for many adults 20 mg — maximum recommended dose 40/60/80 mg — some Vilitra-branded products are marketed at these strengths, but they are not standard/recommended vardenafil doses and shouldn't be used without medical supervision. If you're choosing between Vilitra 10 and 20, 20 mg isn't necessarily better; it also increases the chance of side effects.
