Always inform your doctor about all medications you’re taking, including over-the-counter drugs, herbal supplements, and vitamins. This includes nitrates used to treat chest pain; combining them with Levitra can cause a dangerous drop in blood pressure.
Nitrates and Other Cardiovascular Medications
- Avoid Levitra if you use nitrates in any form (e. g., nitroglycerin, isosorbide). Discuss alternative treatments for erectile dysfunction with your doctor if you have heart problems or take blood pressure medications. Alpha-blockers, often prescribed for high blood pressure or prostate problems, may increase the risk of low blood pressure when combined with Levitra. Your doctor can adjust dosages or suggest alternatives.
Other Potential Interactions
Certain antifungal medications, such as ketoconazole and itraconazole, can increase Levitra’s concentration in your blood, potentially leading to side effects. Similarly, some HIV protease inhibitors can have similar effects. Discuss these interactions with your physician.
Specific Recommendations
Maintain an updated list of all your medications and supplements. Share this list with your doctor and pharmacist before starting any new medication, including Levitra. Report any unusual side effects to your doctor immediately. Never adjust your medication dosage without consulting your doctor.
Grapefruit Juice
Grapefruit juice can interfere with Levitra’s metabolism, leading to increased blood levels of the drug. Avoid grapefruit juice while taking Levitra.
