Folic acid is often prescribed with methotrexate because methotrexate works by inhibiting the enzyme dihydrofolate reductase, which is involved in the synthesis of folic acid. This can lead to a deficiency of folic acid in the body, causing side effects such as mouth sores, nausea, and fatigue. Supplementing with folic acid helps to counteract these side effects and maintain the body's folate levels while still allowing methotrexate to effectively treat conditions such as rheumatoid arthritis, psoriasis, and certain types of cancer. **
