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.
