Methylprednisolone is a corticosteroid medicine that prevents the release of substances in the body that cause inflammation.

Methylprednisolone is used to treat many different inflammatory conditions such as arthritis, lupus, psoriasis, ulcerative colitis, allergic disorders, gland (endocrine) disorders, and conditions that affect the skin, eyes, lungs, stomach, nervous system, or blood cells.

Methylprednisolone may also be used for purposes not listed in this medication guide.

You should not use this medicine if you have a fungal infection anywhere in your body.

Before taking methylprednisolone, tell your doctor about all of your medical conditions, and about all other medicines you are using. There are many other diseases that can be affected by steroid use, and many other medicines that can interact with steroids.

Steroid medication can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. Do not receive a "live" vaccine while using this medicine. The vaccine may not work as well during this time, and may not fully protect you from disease.

Do not stop using methylprednisolone suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication. Any doctor, dentist, or emergency medical professional who treats you should know that you take steroid medication.

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.

Take methylprednisolone exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Your dose needs may change if you have unusual stress such as a serious illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any such situation that affects you.

An overdose of methylprednisolone is not expected to produce life threatening symptoms.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Your doctor may instruct you to follow a low-sodium, low-salt, potassium-rich, or high-protein diet. Follow these directions.

Methylprednisolone may cause an upset stomach. Take methylprednisolone with food or milk.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medication.

Do not receive a "live" vaccine while using methylprednisolone. The vaccine may not work as well during this time, and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, oral typhoid, yellow fever, varicella (chickenpox), and nasal flu (influenza) vaccine.

Get emergency medical help if you have signs of an allergic reaction to methylprednisolone: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to methylprednisolone. Checkups are especially important for children because methylprednisolone can slow bone growth.

If your condition worsens, call your doctor. Your dose may need to be adjusted.

Carry an identification card that indicates that you may need to take supplementary doses (write down the full dose you took before gradually decreasing it) of methylprednisolone during periods of stress (injuries, infections, and severe asthma attacks). Ask your pharmacist or doctor how to obtain this card. List your name, medical problems, drugs and dosages, and doctor's name and telephone number on the card.

This drug makes you more susceptible to illnesses. If you are exposed to chicken pox, measles, or tuberculosis (TB) while taking methylprednisolone, call your doctor. Do not have a vaccination, other immunization, or any skin test while you are taking methylprednisolone unless your doctor tells you that you may.

Report any injuries or signs of infection (fever, sore throat, pain during urination, and muscle aches) that occur during treatment.

Your doctor may instruct you to weigh yourself every day. Report any unusual weight gain.

If your sputum (the matter you cough up during an asthma attack) thickens or changes color from clear white to yellow, green, or gray, call your doctor; these changes may be signs of an infection.

If you have diabetes, methylprednisolone may increase your blood sugar level. If you monitor your blood sugar (glucose) at home, test your blood or urine more frequently than usual. Call your doctor if your blood sugar is high or if sugar is present in your urine; your dose of diabetes medication and your diet may need to be changed.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
