Does Mometasone Interact with Clarithromycin?
CDI records a moderate classification for Mometasone and Clarithromycin. The stored summary is: Caution should be exercised when considering the co-administration of mometasone furoate nasal spray with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, cobicistat-containing products, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Clinical Pharmacology (12.3) ] . Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug.

What To Tell Your Doctor or Pharmacist
If you are taking Mometasone and your doctor is considering prescribing Clarithromycin (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 whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
