Mext 7.5 F contains Methotrexate and Folic Acid, used to control joint inflammation and prevent joint damage in conditions like rheumatoid arthritis. Folvite contains Folic Acid (Vitamin B9). Methotrexate can deplete your body's folate, leading to side effects like mouth sores, nausea, and liver strain; Folvite is prescribed to safely counteract these side effects. This combination is highly effective and safe for long-term use under strict medical supervision. Because Methotrexate can affect your liver and blood counts, your doctor will schedule regular blood tests to monitor your health. Always take these medications exactly as prescribed.
