What Is Methotrexate?
Simply put, methotrexate is a specialized medicine used to treat several different medical conditions. It helps calm your immune system and slow down the rapid growth of specific cells in your body.

Your doctor might also recommend this medicine for other specific health needs based on your personal medical history. Always talk with your doctor if you have any questions about why you need this treatment.

This is the most important part of your treatment routine. You must follow your doctor instructions exactly to stay safe.

Taking this medicine more often than prescribed can cause severe, life-threatening side effects. Always double-check your schedule with your pharmacist or doctor.
