Why don't rheumatologists routinely test for MTHFR before prescribing folic acid with methotrexate?
This is a thoughtful question about personalized treatment approaches. While the search results don't specifically address MTHFR testing protocols, here's what's known about folic acid supplementation with methotrexate:
Folic acid supplementation is standard practice when taking methotrexate because the medication blocks natural folate production, which can cause side effects like mouth sores and gastrointestinal issues. Studies show folic acid supplements can reduce these side effects by 79 percent without affecting methotrexate's effectiveness in treating RA.
The dosage and frequency of folic acid varies by individual - some people take one 5-mg dose weekly, while others take smaller daily doses. Your rheumatologist determines the best regimen based on your specific needs and how you respond to treatment.
If you're concerned about MTHFR variations or think methylfolate might be more appropriate for you, this is definitely worth discussing with your rheumatologist. They can consider your individual situation and whether alternative forms of folate supplementation might be beneficial.
