Does Vardenafil Interact with Nifedipine?
CDI records a unknown classification for Vardenafil and Nifedipine. The stored summary is: In vivo studies Nifedipine: Vardenafil 20 mg (film-coated tablets), when co-administered with slow-release nifedipine 30 mg or 60 mg once daily, did not affect the relative AUC or C max of nifedipine, a drug that is metabolized via CYP3A4. Nifedipine did not alter the plasma levels of vardenafil when taken in combination. Vardenafil orally disintegrating tablet, when co-administered with slow-release nifedipine 30 mg or 60 mg once daily in patients whose hypertension was controlled with nifedipine, produced mean additional supine systolic/diastolic blood pressure reductions of 3/4 mmHg (age group 65 to 69 years) and 5/5 mmHg (age group 70 to 80 years) compared to placebo. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

What To Tell Your Doctor or Pharmacist
If you are taking Vardenafil and your doctor is considering prescribing Nifedipine (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Never stop or change either medication without first consulting your healthcare provider
