Which statement best describes the adverse effects of valproate that require monitoring?

• A. Hepatotoxicity only.
• B. Thrombocytopenia only.
• C. Pancreatitis only.
• D. Hepatotoxicity, thrombocytopenia, pancreatitis, and teratogenicity.

Answer: (D)

Valproate carries several serious adverse effects that require regular monitoring to prevent harm. Hepatotoxicity is a key concern, so liver function tests (like AST/ALT and bilirubin) are checkedBaseline and periodically, with any signs of liver dysfunction prompting reevaluation of therapy. Thrombocytopenia is another risk; a complete blood count helps detect low platelets that could increase bleeding risk, and patients are advised to report easy bruising or abnormal bleeding. Pancreatitis, though less common, can be life-threatening and presents with persistent abdominal pain and vomiting, so clinicians monitor for these symptoms and may check pancreatic enzymes if suspected. Teratogenicity is a major issue in women of childbearing potential; valproate exposure in pregnancy is linked to neural tube defects and other congenital abnormalities, so pregnancy status must be reviewed, counseling provided, and contraception or alternative therapies considered as appropriate. Because all of these areas require monitoring, the statement that encompasses hepatotoxicity, thrombocytopenia, pancreatitis, and teratogenicity best describes the adverse effects needing surveillance.
