As trimethoprim is a folic acid antagonist, there are concerns that periconceptual/perinatal use may limit the availability of folic acid and impact the

A type of drug that stops cells from using folic acid to make DNA and may kill cancer cells. Certain folic acid antagonists are used to treat some types of cancer and inflammatory conditions, such as rheumatoid arthritis. Also called antifolate and folate antagonist.
1) Neutralising the immediate toxic effects of folic acid antagonists, e.g, Methotrexate. 2) Calcium Folinate Rescue - a treatment technique using calcium folinate in conjunction with folic acid antagonists, e.g, methotrexate, to minimise systemic toxicity.
Drugs in the category include methotrexate and 5-fluorouracil (folic acid antagonists); azathioprine, mercaptopurine, and 6-thioguanine (purine antagonists);
Methotrexate is a folate antagonist. Methotrexate inhibits dihydrofolate reductase (DHFR), the enzyme that reduces folic acid to tetrahydrofolic acid.
