Levitra (Vardenafil): Uses, Dosage, Side Effects & How It Compares
Levitra, the brand name for Vardenafil, is a prescription medication used to treat erectile dysfunction (ED) in men. Similar to Viagra and Cialis, Levitra belongs to a class of drugs known as PDE5 inhibitors and helps improve blood flow to the penis during sexual stimulation.
With a slightly faster onset than some other ED medications and a reputation for fewer visual side effects, Levitra is often recommended for men who don’t respond well to other treatments.
What is Levitra (Vardenafil)?
Levitra is designed to treat erectile dysfunction—a condition where a man is unable to achieve or maintain an erection sufficient for sexual activity. Vardenafil enhances the effects of nitric oxide, a natural chemical that relaxes muscles in the penis and increases blood flow during arousal.
How Levitra Works
Vardenafil inhibits the phosphodiesterase type 5 (PDE5) enzyme, which can restrict blood flow. By blocking this enzyme, Levitra increases cGMP levels, promoting better blood circulation in the penis when sexually aroused. It does not work without sexual stimulation.
Approved Uses
- Erectile Dysfunction (ED)
Unlike Tadalafil (Cialis), Levitra is not approved for treating benign prostatic hyperplasia (BPH) or pulmonary hypertension.
Dosage and Administration
Levitra is available in 2.5 mg, 5 mg, 10 mg, and 20 mg tablet strengths.
- Typical starting dose: 10 mg, taken orally 30 to 60 minutes before sex
- Max dose: 20 mg in 24 hours
- Take with or without food (but avoid high-fat meals for better effectiveness)
How Long Does Levitra Last?
- Onset: 25 to 60 minutes
- Duration: 4 to 5 hours
It works best when taken an hour before planned activity, though it can remain effective within a 5-hour window.
