Vitamin A Toxicity

Vitamin A toxicity is an uncommon but clinically important condition caused by excessive exposure to preformed vitamin A or systemic retinoids. Toxicity may be acute, chronic, or teratogenic and can affect hepatic, skeletal, neurologic, dermatologic, metabolic, and fetal development outcomes. Clinical recognition may be challenging because symptoms such as fatigue, headache, dry skin, bone pain, nausea, laboratory abnormalities, and increased intracranial pressure can overlap with other disorders. The existing practice gap involves inconsistent identification of high-risk exposures, limited recognition of subclinical or chronic toxicity, and variable monitoring of patients receiving retinoid therapy or multiple vitamin A sources. This activity addresses the gap by reviewing risk factors, diagnostic evaluation, evidence-based treatment, complication prevention, patient education, and interprofessional coordination. Participants will gain actionable strategies to improve exposure assessment, diagnostic accuracy, laboratory interpretation, medication safety, and patient-centered outcomes.
