Levitra (vardenafil) is an oral prescription treatment for erectile dysfunction, a condition where a man has difficulty getting or keeping an erection firm enough for sex. Vardenafil blocks PDE5, increasing blood flow to the penis when a man is sexually stimulated. It does not raise sexual desire and will not produce an erection without stimulation.
Levitra contains vardenafil hydrochloride, a PDE5 inhibitor. Vardenafil acts on the nitric oxide–cGMP pathway involved in penile erection, relaxing blood vessels and increasing blood flow during sexual stimulation.
Levitra (vardenafil) is prescribed for: Erectile dysfunction (ED) Difficulty getting an erection Difficulty keeping an erection during sexual activity Vardenafil does not treat the underlying cause of ED, raise libido, prevent pregnancy, or protect against sexually transmitted infections.
Sexual stimulation triggers the release of nitric oxide, which drives cGMP production and relaxes smooth muscle in the penis. Vardenafil blocks PDE5, the enzyme that breaks down cGMP, helping maintain increased blood flow during stimulation.
Levitra is taken as needed, not daily. The historical FDA prescribing information lists 10 mg as the standard starting dose, taken about 60 minutes before sexual activity, with adjustment to 5 mg or 20 mg based on how well it works and how well it is tolerated. The recommended maximum is one dose per day. It can be taken with or without food. Follow the dose and strength instructions from the prescribing healthcare professional.
Do not take Levitra with nitrates or nitric oxide donors. This combination can cause a dangerous drop in blood pressure. Tell your healthcare professional if you have cardiovascular disease or have been advised to avoid sexual activity for medical reasons. Vardenafil can interact with certain medicines, including some alpha-blockers and CYP3A4 inhibitors; dose adjustments may be needed. Seek immediate medical attention for an erection lasting more than four hours, sudden vision loss, sudden hearing loss, or severe cardiovascular symptoms. Common Side Effects Possible side effects include: Headache Flushing Indigestion Nasal congestion Dizziness Back pain Side effects vary. Contact a healthcare professional if symptoms are severe or persistent.
