Psychiatric Medications and Hypertriglyceridemia

Atypical Antipsychotics and Hypertriglyceridemia

Atypical antipsychotics are the primary psychiatric medications that can cause hypertriglyceridemia, with clozapine and olanzapine having the highest risk, followed by quetiapine and risperidone, while aripiprazole and ziprasidone have lower risk 1, 2
Aripiprazole is associated with fewer metabolic effects and lower risk of hyperlipidemia, according to the American Diabetes Association 3
Ziprasidone is considered to have minimal effects on lipid metabolism compared to other atypical antipsychotics, as reported by the American Diabetes Association 3

Severe hypertriglyceridemia (>500 mg/dL) increases risk of acute pancreatitis, as stated by the American Heart Association and the American Academy of Family Physicians 1, 4
Very severe hypertriglyceridemia (>2,000 mg/dL) significantly increases pancreatitis risk, according to the American Academy of Family Physicians 4

Valproic acid can cause weight gain and may contribute to elevated triglycerides, as reported by the American Gastroenterological Association 5
Carbamazepine has been associated with weight gain that may affect lipid profiles, according to the American Gastroenterological Association 5
Lithium can cause weight gain that may indirectly affect triglyceride levels, as stated by the American Gastroenterological Association 6
Most SSRIs are generally weight-neutral or may cause weight loss initially, according to the American Gastroenterological Association 6
Mirtazapine is associated with weight gain that could indirectly affect triglycerides, as reported by the American Gastroenterological Association 6

When possible, select antipsychotics with lower metabolic risk in patients with pre-existing dyslipidemia or metabolic syndrome, as recommended by the American Diabetes Association 3

Severe hypertriglyceridemia (≥500 mg/dL) increases the risk of acute pancreatitis, as reported by the American Diabetes Association 7

Nonpharmacological management of high triglycerides includes weight loss, reduction in alcohol consumption, smoking cessation, and increased physical activity, as recommended by the American College of Cardiology 8
Pharmacological options for managing antipsychotic-induced hypertriglyceridemia include fibrates, niacin, and omega-3 fatty acids when lifestyle modifications are insufficient, according to the Metabolism: Clinical and Experimental journal 9
Statin plus fibrate combination therapy is generally not recommended as it has not been shown to improve cardiovascular outcomes, as stated by the American Diabetes Association 7
Similarly, statin plus niacin combination therapy is not recommended due to lack of cardiovascular benefit and potential increased risk of stroke, as reported by the American Diabetes Association 7
