Anneke: you're not being pedantic I believe you are correct.That is why some people still prefer the terms pseudotumor cerebri, and pseudotumor cerebri syndrome and to specify secondary causes. This keeps the same name, but makes it a little easier to deal with the idiopathic versus the known causes.

Can you call it IIH if it's caused by vit A? Sorry to be pedantic!

In this remarkable paper called 'Liver Lover's Headache' by Selhorst, Jennings, and Corbett, IIH was seen in individuals who consumed a
shocking amount of liver in their diet (with estimated vitamin A intake of 60,000 to 340,000 IU!).

That was my mistake. I wrote 100,000 U and meant 10,000, although one dose of vitamin A above 10K units would not necessarily cause disk swelling and headaches.

from OpenEvidence:
An oral dose of vitamin A is considered toxic when it exceeds 10,000 IU (3,000 μg retinol activity equivalents) per day for adults as a chronic intake, and acute toxicity can occur at single doses of 25,000 IU/kg or more. Chronic toxicity is associated with daily intakes above this threshold, leading to manifestations such as hepatotoxicity, reduced bone density, and increased intracranial pressure. The American Academy of Ophthalmology specifically notes that daily doses above 10,000 IU exceed the FDA-recommended tolerable upper intake level for adults, and chronic intakes above this level are associated with toxicity risks. The U.S. Food and Drug Administration also identifies acute toxicity at single oral doses of 25,000 IU/kg and chronic toxicity at daily intakes of 4,000 IU/kg for several months, with clinical symptoms including liver abnormalities and central nervous system effects.[1-2] Long-term supplementation studies in adults have shown that daily intakes below 25,000 IU are generally safe, but doses at or above this level are considered potentially toxic over the long term.[3] The risk of toxicity is higher in certain populations, such as children, the elderly, and those with liver disease or high alcohol intake.[1-2] In summary, chronic oral intake of vitamin A above 10,000 IU per day in adults is considered toxic, and acute toxicity can occur at much higher single doses.[1-3] 2.AQUASOL A.

Just for my education- what Vitamin A dose would we consider to be significant enough to avoid?

Hello all,
I have a patient with IIH who is lactose intolerant and takes oat milk but is worried that it contains Vitamin A, I looked at dosages and it is anywhere between 90-180mcg Vitamin A added. Is this something that our IIH patients should avoid?
Thanks,
Shruthi Harish
