Summary
Atypical antipsychotics, including cariprazine, can cause hyperglycemia and weight gain, which may reduce the effectiveness of glucose-lowering therapy. Patients taking metformin may need closer glycemic monitoring when cariprazine is started or adjusted. Metformin may in fact help counter antipsychotic-related weight gain.
What this interaction means in plain words
Cariprazine and Metformin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Cariprazine belongs to Central Nervous System; Metformin belongs to Endocrine.
Why it happens
Antipsychotic-induced insulin resistance and metabolic changes oppose the glucose-lowering effect of metformin.
What to do
Monitor fasting glucose or HbA1c and weight after starting cariprazine. Adjust the antidiabetic regimen if control worsens.
