It is a uw q. UW says that toxicity of vit A can be divided into acute, chronic and teratogenic syndromes.

Acute follows a large dose of vit A and consists of nausea, vomiting, vertigo and blurred vision.

Chronic follows longterm use of high doses of vit A and include alopecia, dry skin, hyperlipidemia, hepatotoxicity, hepatosplenomegaly, and visual difficulties.

Papilledema when present is suggestive of cerebral edema in the setting of benign intracranial hypertension.

Teratogenic effects include microcephaly, cardiac anomalies, and fetal death (especially in the first trimester.)
