Choline magnesium trisalicylate + Vitamin c

MediHelp rates the interaction as minor. Choline magnesium trisalicylate and Vitamin c have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised. Ascorbic acid may acidify urine and modestly reduce renal excretion of salicylate, while salicylates can increase urinary loss of ascorbic acid. The net effect is usually small, but salicylate levels could rise slightly with high vitamin C doses.

MediHelp rates it minor, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: No routine adjustment is needed; watch for salicylate toxicity signs such as tinnitus if large vitamin C doses are started or stopped in patients on high-dose salicylate.

MediHelp also lists interactions of Vitamin c with, for example, Deferoxamine, Aluminum hydroxide, Dextroamphetamine transdermal. The full list is on the Vitamin c page.
