Tadalista 40 is a medication used for the treatment of erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil helps increase blood flow to the penis, facilitating the ability to achieve and maintain an erection during sexual stimulation. Limit or avoid alcohol consumption while using Tadalista 40, as excessive alcohol can increase the risk of side effects. Grapefruit or grapefruit juice should also be avoided, as it may interact with the medication.
