How should this medicine be used? 

Methylprednisolone comes as a tablet to take by mouth. Your doctor will prescribe a dosing schedule that is best for you. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take methylprednisolone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.


Do not stop taking methylprednisolone without talking to your doctor. Stopping the drug abruptly can cause loss of appetite, upset stomach, vomiting, drowsiness, confusion, headache, fever, joint and muscle pain, peeling skin, and weight loss. If you take large doses for a long time, your doctor probably will decrease your dose gradually to allow your body to adjust before stopping the drug completely. Watch for these side effects if you are gradually decreasing your dose and after you stop taking the tablets. If these problems occur, call your doctor immediately. You may need to increase your dose of tablets temporarily or start taking them again.
