Vardenafil’s effects can be altered by other medications. Nitrates, like nitroglycerin, are contraindicated due to the risk of severe hypotension. Avoid concomitant use.
Alpha-blockers, commonly used for hypertension or benign prostatic hyperplasia, may enhance Vardenafil’s hypotensive effects. Monitor blood pressure closely if you are taking both.
CYP3A4 inhibitors, such as ketoconazole and ritonavir, can increase Vardenafil blood levels, potentially intensifying side effects. Your doctor may adjust your Vardenafil dosage.
Conversely, CYP3A4 inducers, like rifampin, can reduce Vardenafil’s effectiveness. Discuss alternative treatment options with your physician.
Strong inhibitors of CYP2C9, including fluconazole, can elevate Vardenafil plasma concentrations. Careful monitoring is necessary. Dosage adjustment might be required.
Grapefruit juice inhibits CYP3A4; avoid concurrent consumption with Vardenafil, as this may lead to elevated blood levels and amplified side effects.
Always inform your doctor about all medications, supplements, and herbal remedies you are taking to minimize potential drug interactions.
