Vidalista tablets contain tadalafil, a medication used to treat erectile dysfunction. Tadalafil is a member of the phosphodiesterase type 5 inhibitor drug class. By inhibiting PDE5, it supports higher cGMP levels, which in turn encourage smooth muscle relaxation and improved blood flow to the penis. Follow the dosage precisely as prescribed; do not take it more or less frequently than once a day. Common side effects include headache, flushing, nasal congestion, dizziness, and indigestion. Most of the time, these adverse effects are mild and transient. You must not drive if this drug makes you dizzy. Avoid drinking while using this medication as it raises the chance of negative effects.
