The risk of toxicity from folic acid is low because folate is a water-soluble vitamin and is regularly removed from the body through urine. One potential issue associated with high doses of folic acid is that it has a masking effect on the diagnosis of pernicious anaemia due to vitamin B 12 deficiency, and may even precipitate or exacerbate ...
Folinic acid, also known as leucovorin, is a medication used to decrease the toxic effects of methotrexate and pyrimethamine.

Both high-folate diets and supplemental folic acid may help reduce the toxic side-effects of low-dose methotrexate without decreasing its effectiveness. [8] [9] Anyone taking low-dose methotrexate for the health problems listed above should consult with a physician about the need for a folic acid supplement.
The large-scale study, which looked at the data of 867,000 American adults over two years, showed a beneficial association between taking prescription folic acid — a B vitamin that helps the ...
The elderly are at increased risk because they tend to produce less stomach acid as they age, a condition known as achlorhydria, thereby increasing their probability of B 12 deficiency due to reduced absorption. [2] Nitrous oxide overdose or overuse converts the active monovalent form of vitamin B12 to the inactive bivalent form. [38]
