Summary

Both cyclosporine and long-term proton pump inhibitors can lower serum magnesium, so combined use may increase the risk of hypomagnesemia. Omeprazole may also modestly alter cyclosporine levels in some patients.

What this interaction means in plain words

Cyclosporin and Omeprazole can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Cyclosporin belongs to Miscellaneous; Omeprazole belongs to Gastrointestinal Tract.

Evidence level: Low

Why it happens

Additive magnesium loss through renal wasting (cyclosporine) and reduced intestinal absorption (PPIs), with minor CYP-mediated effects.

What to do

Monitor serum magnesium periodically in long-term use and replace as needed. Check cyclosporine trough levels when omeprazole is started or stopped.

What to ask your pharmacist

  • Should I take them at different times of day?
