Does Captopril Interact with Aliskiren?

CDI records a contraindicated classification for Captopril and Aliskiren. The stored summary is: Do not coadminister with captopril in patients with diabetes. Avoid use in patients with renal impairment (GFR < 60 ml/min) due to increased risk of hypotension, hyperkalemia, and acute renal failure. The mechanism involves dual ras blockade. 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.

If you are taking Captopril and your doctor is considering prescribing Aliskiren (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
Ask about alternative medications that do not interact with your current regimen
Ask how frequently you should be monitored while these are co-prescribed
Never stop or change either medication without first consulting your healthcare provider

How this information is prepared: CDI uses automated extraction, including AI, to summarize drug labeling from openFDA and includes separately identified curated-reference records. RxNorm helps identify medications; it does not verify interaction claims. Extracted summaries and CDI severity classifications can contain errors and are not verbatim FDA statements or independent clinical review. Maintained by CheckDrugInteractions.com. See our methodology or report a correction at support@checkdruginteractions.com.

Data sourced from U.S. FDA drug labeling via openFDA and the NIH National Library of Medicine, supplemented with a small number of well-established interactions from curated clinical references. For informational purposes only. Always consult your pharmacist or physician.
