Viagra ( Sildenafil )
Levitra vs. Viagra: Differences, similarities, and which is better for you
If you are one of the 15 to 30 million men in the United States who suffers from erectile dysfunction, you may have talked with your doctor about trying a prescription medication. Levitra and Viagra are two popular medications used for the treatment of erectile dysfunction (ED). They are classified in a group of medications called PDE-5 (phosphodiesterase-5) inhibitors. Other drugs in this category include Cialis (tadalafil) and Stendra (avanafil).
PDE5 inhibitors work in conjunction with sexual stimulation—increasing the levels and activity of nitric oxide—leading to better blood flow to the penis and causing an erection. They also prolong erections and increase sexual satisfaction. Although Levitra and Viagra are both PDE-5 inhibitors and are very similar, they have some notable differences.
What are the main differences between Levitra and Viagra?
Levitra (vardenafil), also known by its generic name vardenafil, and Viagra, also known by its generic name, sildenafil, are both PDE-5 inhibitors. Both drugs are available in tablet form as brand and generic.
Regardless of dose, these medications should not be taken more than once in a day in the treatment of ED. Levitra or Viagra needs to be accompanied by sexual stimulation in order to work.

Conditions treated by Levitra and Viagra
Levitra and Viagra are indicated for the treatment of erectile dysfunction. Both drugs have been used off-label for Raynaud’s phenomenon or for female sexual arousal disorder. The form of sildenafil known as Revatio (NOT Viagra) is indicated for the treatment of pulmonary arterial hypertension, only at the dose of 20 mg three times daily, and not at the doses Viagra is available in (25 mg, 50 mg, or 100 mg).

Is Levitra or Viagra more effective?
From clinical studies, we know that both Levitra and Viagra have been proven effective, but which is better? In a study comparing drugs for ED, Levitra was described as more potent than Viagra; however, both drugs were shown to be similarly effective in the treatment of ED. The only advantage Levitra had was that it did not alter color perception, which may occur with Viagra on rare occasions. Another study found both drugs to be well-tolerated, with Levitra being nominally better than Viagra.
The most effective drug for you can only be determined by your healthcare provider, who will take into account your medical history and condition(s), as well as other medications you are taking that could interact with Levitra or Viagra.

Drug interactions of Levitra vs. Viagra
Levitra and Viagra should never be used with nitrates, such as nitroglycerin. The combination is contraindicated (should not be used) because it could result in dangerously low blood pressure. Alpha blockers, such as alfuzosin, terazosin, or tamsulosin, can cause the same effect of low blood pressure when taken with Levitra or Viagra. Any antihypertensives (medications to lower blood pressure) in combination with Levitra or Viagra can also interact, causing low blood pressure.
Levitra or Viagra can also interact with azole antifungals, protease inhibitors, and macrolide antibiotics. Other drug interactions may occur; consult your healthcare professional for a full list of drug interactions.
|Macrolide antibiotic||Yes||Yes (but not azithromycin)|
Warnings of Levitra and Viagra
- Levitra or Viagra should not be given with any nitrate medication (such as nitroglycerin), because the combination can lead to a dangerous decrease in blood pressure.
- Cardiovascular health should be evaluated. If a patient has certain heart/blood pressure problems, the medication may be unsafe. Consult your healthcare provider.
- Use with caution in patients with anatomical deformations of the penis.
- Rarely, prolonged erection (over 4 hours) or priapism (painful erection over 6 hours) may occur. If an erection lasts longer than 4 hours, seek immediate medical care. Failing to treat this immediately could result in permanent damage.
- Stop taking Levitra or Viagra and seek immediate medical care if you have a sudden loss of vision in one or both eye(s).

- Dosage adjustment is required for patients with moderate liver issues. Levitra or Viagra should not be used in patients with severe liver problems.
