Does Rapamycin Interact with Ranolazine?
CDI records a major classification for Rapamycin and Ranolazine. The stored summary is: CYP3A substrate with narrow therapeutic range. Dose adjustment may be required as ranolazine increases plasma concentrations. The mechanism involves cyp3a substrate; ranolazine inhibits cyp3a. 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 Rapamycin and your doctor is considering prescribing Ranolazine (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 how frequently you should be monitored while these are co-prescribed
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
