Does Midazolam Interact with Quinine Sulfate?
CDI records a unknown classification for Midazolam and Quinine Sulfate. The stored summary is: Midazolam (CYP3A4 Substrate) In 23 healthy subjects who received multiple doses of quinine sulfate capsules, 324 mg three times daily x 7 days with a single oral 2 mg dose of midazolam, the mean AUC and C max of midazolam and 1-hydroxymidazolam were not significantly affected. This finding indicates that 7-day dosing with quinine sulfate capsules,324 mg every 8 hours did not induce the metabolism of midazolam. 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 Midazolam and your doctor is considering prescribing Quinine Sulfate (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
