Significance
-
Occurring in approximately 15 percent of patients, headaches are the most common side effect of Levitra, according to the U.S. National Library of Medicine.
Features
-
Headaches from Levitra occur most frequently at higher doses. This means that men taking the 20mg dose of the medication are more likely to experience headaches than those taking the 5mg or 10mg doses, according to the U.S. National Library of Medicine.
-
Drug Interactions
-
Prescription drugs like the antibiotic erythromycin, the antifungal drug ketoconazole or HIV protease-inhibitors like indinavir have the potential to increase concentrations of Levitra in your bloodstream, according to the U.S. National Library of Medicine. Because of this, using a combination of Levitra and any of these drugs may increase your risk for developing headaches.
Warning
-
Although in many cases, headaches caused by Levitra are not serious in nature, the Mayo Clinic advises men who experience them to notify their doctors in order to rule out any possible complications from the drug, such as low blood pressure.
Considerations
-
Men older than 65 are more likely than other men to develop side effects from Levitra, including headaches, according to the Mayo Clinic. Because of this, doctors often begin older men at a lower dosage.
