Which is a contraindication for carbamazepine?

• A. Pregnancy
• B. Asthma
• C. Kidney disease
• D. Diabetes

Answer: (A)

The main concept here is that carbamazepine can cause birth defects, so it is avoided during pregnancy. It is considered contraindicated in pregnancy because it is teratogenic and increases the risk of major congenital malformations, including neural tube defects. In contrast, asthma, kidney disease, and diabetes do not by themselves make carbamazepine unsafe in all cases; they may require careful monitoring or dose adjustments but are not absolute contraindications like pregnancy. If pregnancy is a consideration, clinicians typically look for safer alternatives for seizure or mood stabilization and weigh risks and benefits carefully.
