MinorMineral supplements. Calcium×Psycholeptics. Lithium
Updated · Methodology
Mechanism
Calcium carbonate as an antacid mildly reduces lithium intestinal absorption, but no clinically significant drop in blood concentration has been documented.
Symptoms
The combination usually causes no specific symptoms. Each drug's individual side effects remain.
Management
No dose adjustment needed. Check lithium levels on the usual schedule (every 3 months on stable dose). With significant clinical changes (return of manic or depressive symptoms), check off-schedule.
Check the full regimen, not just this pair
Opens the checker with these two drugs prefilled. Add the rest of the regimen and recompute additive risks.
