Levitra

Special information if you are pregnant or breastfeeding

Levitra should not be used by women. Its effects during pregnancy and breastfeeding have not been studied.

Recommended dosage

ADULT MALES

Doses range from 5 milligrams to 20 milligrams, depending on the drug's effect. The recommended starting dose is 10 milligrams for most people. However, if you're 65 or older, the doctor may start you at 5 milligrams.

Take Levitra only before sexual activity. The manufacturer recommends a maximum of one dose per day. However, your doctor may need to lower the dose if you're taking certain drugs that affect the liver, including erythromycin, indinavir (Crixivan), itraconazole (Sporanox), ketoconazole (Nizoral), and ritonavir (Norvir).

If you have moderate liver impairment, the recommended starting dose is 5 milligrams, not to exceed a daily dose of 10 milligrams. If your liver problems are mild, no dosage adjustment is required.

Overdosage

A small study found that a single 120-milligram dose of Levitra caused reversible side effects such as vision changes and back and muscle pain. However, any medication taken in excess can have serious consequences. If you suspect an overdose, seek medical attention immediately.
