Folinic acid, also known as leucovorin, is a medication used to decrease the toxic effects of methotrexate and pyrimethamine. [2] [3] It is also used in combination with 5-fluorouracil to treat colorectal cancer and pancreatic cancer, may be used to treat folate deficiency that results in anemia, and methanol poisoning.
For many biologics (e.g., monoclonal antibodies), injection site reactions are the most common adverse effect of the drug, and have been reported to have an incidence rate of 0.5–40%. [2] In trials of subcutaneous administration of oligonucleotides, between 22 and 100% of subjects developed reactions depending on the oligonucleotide. [6]
They are given by injection. [2] Common side effects may include joint pain, rash, vomiting, and headache. [4] Serious side effects may include heart attacks, stroke, increased cancer growth, or pure red cell aplasia. [2] It is unclear if use is safe during pregnancy. [5] [6] They work similar to naturally occurring erythropoietin. [1]
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 2013–2014 survey reported that for adults ages 20 years and older, men consumed an average of 249 μg/day folate from food plus 207 μg/day of folic acid from consumption of fortified foods, for a combined total of 601 μg/day of dietary folate equivalents (DFEs because each microgram of folic acid counts as 1.7 μg of food folate).
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
One study in 184 premature infants, reported that individuals given monthly vitamin B 12 injections (100 μg) or taking supplements of vitamin B 12 and folic acid (100 μg/day), had higher haemoglobin concentrations after 10–12 weeks, compared to those only taking folic acid or those taking no vitamin B 12 injections. [87]
Common side effects include nausea, vomiting, loss of appetite, and skin rashes. It is a sulfonamide and bacteriostatic. It resembles a component of folic acid. It prevents folic acid synthesis in the bacteria that must synthesize their own folic acid.
