There is no evidence to recommend vitamin B12 supplementation to help ease nausea or other side effects of methotrexate. Pediatric rheumatologists usually prescribe folic acid or folinic acid (leucovorin) supplementation, which helps reduce some of the methotrexate side effects, such as stomach upset, nausea and liver toxicity. There are many ways of prescribing folic [...]

However, WBCs are overactive in autoimmune diseases [...]
The dose of methotrexate is generally prescribed by a child’s weight, with the dose calculated based on a calculated body surface area.
