Vidalista 20 mg should not be used by individuals who are allergic to Tadalafil or have certain health conditions that contraindicate its use, such as severe heart problems, severe liver or kidney disease, or those taking nitrates. Tadalafil, the active ingredient, inhibits the enzyme phosphodiesterase type 5 (PDE5). This inhibition leads to the relaxation of blood vessels in the pill allowing increased blood flow and facilitating an erection in response to physical stimulation.
