Vardenafil, sold under the brand name Levitra and available as a generic medication, is a phosphodiesterase-5 (PDE-5) inhibitor used to treat erectile dysfunction (ED) in men. The medication works by relaxing smooth muscle tissue in the penis and increasing blood flow, helping men achieve and maintain an erection during sexual stimulation. It does not increase sexual desire and is not effective without sexual arousal.

Sudden vision loss — A rare but serious condition called non-arteritic anterior ischemic optic neuropathy (NAION); seek immediate medical care if vision changes occur. Sudden hearing loss — Uncommon but possible; manifests as ringing in the ears, muffled hearing, or sudden deafness in one or both ears. Chest pain or pressure — May indicate a serious heart condition; stop use and call 911 or seek emergency care immediately. Severe drop in blood pressure — Particularly when combined with certain other medications, leading to dizziness, fainting, or heart problems. Priapism — A prolonged, painful erection lasting more than 4 hours; requires immediate emergency care to prevent permanent damage. Contact your healthcare provider immediately if you experience chest pain, difficulty breathing, sudden vision or hearing changes, or an erection lasting more than 4 hours. These symptoms, while rare, require urgent evaluation.

Additionally, notify your doctor if common side effects persist beyond a few hours, worsen over time, or significantly interfere with your daily life.

Seek prompt medical attention if you experience these effects.

Vardenafil compared to other PDE5 inhibitors

Levitra and Cialis belong to the same class of drugs called PDE5 inhibitors, but they are not the same drugs. These drugs contain different active ingredients and can be used in different ways. Cialis is available as a once-daily pill, while Levitra is only taken as needed. Choosing which is better can depend on personal preferences and how often you plan to be intimate. Cialis may work faster and have effects that last longer than vardenafil. Important: Do not take vardenafil more than once daily. If you miss a dose, take it when you remember before sexual activity—do not double up.
