Levitra: Everything You Need to Know About Vardenafil for Erectile Dysfunction
What is Levitra? Complete Overview of This ED Medication
Levitra, the brand name for vardenafil, is a highly effective oral medication prescribed for the treatment of erectile dysfunction (ED) in men. As a member of the PDE5 inhibitor family—alongside well-known drugs such as Viagra (sildenafil) and Cialis (tadalafil)—Levitra is recognized for its rapid onset, reliability, and tolerability.
Key Facts at a Glance:
- Active ingredient: Vardenafil hydrochloride
- Onset of action: Typically within 25-60 minutes
- Duration of effect: Up to 5-6 hours
- Prescription status: Prescription-only in most countries
- Used for: Treating erectile dysfunction (impotence)
| PDE5 Inhibitor | Onset | Duration | Food effect |
|---|---|---|---|
| Levitra (Vardenafil) | 25-60 min | 5-6 hours | Less food interaction |
| Viagra (Sildenafil) | 30-60 min | 4 hours | Reduced by fatty meals |
| Cialis (Tadalafil) | 30-45 min | 36 hours | Minimal |
How Does Levitra Work? Mechanism of Action Explained
When men experience erectile dysfunction, a key biological culprit is the enzyme PDE5 (phosphodiesterase type 5), which breaks down cGMP—a compound that relaxes penile blood vessels. Levitra (vardenafil) blocks PDE5, increasing cGMP levels. This action boosts blood flow to the penis during sexual stimulation, enabling a firm erection.
Important: Levitra will not trigger an automatic erection. Sexual arousal is still required for the medication to be effective.
What Sets Levitra Apart from Other ED Drugs?
- More selective inhibition of PDE5—may reduce the risk of certain side effects
- Reportedly less affected by food intake (compared to Viagra)
- Effective for men with underlying conditions (e.g., diabetes, hypertension)
Who Should Use Levitra? Indications & Who Should Avoid
Levitra is FDA/EMA approved for men over 18 years old who have difficulty achieving or maintaining an erection. It’s suitable for a wide spectrum of ED causes, including psychological, vascular, and neurologic factors.
Not recommended for:
- Women & children
- Men with known hypersensitivity to vardenafil
- Patients currently taking nitrates or nitric oxide donors (dangerous drop in blood pressure risk)
- Individuals with severe heart/liver impairment—consult a physician
Can Diabetics Use Levitra?
Yes—studies such as Goldstein et al., New England Journal of Medicine 2003, show good efficacy and tolerability in men with diabetes-related ED.
How to Use Levitra Safely: Dosage & Administration Guidelines
The typical starting dose of Levitra for most men is 10 mg, taken orally about 25-60 minutes before planned sexual activity. The dose can be increased to 20 mg or decreased to 5 mg depending on response and tolerability.
- Take with or without food: Heavy, fatty meals may delay absorption slightly, but not as much as with sildenafil.
- Do not take more than once daily.
- Alcohol: Consume in moderation, as excessive use may amplify side effects.
| User group | Recommended starting dose | Max dose/interval |
|---|---|---|
| Healthy adult men | 10 mg | 20 mg once/day |
| Over 65 years, mild renal/liver impairment | 5 mg | 20 mg once/day |
| With moderate hepatic impairment | 5 mg | 10 mg once/day |
