How does this medication work? What will it do for me?
Methylprednisolone belongs to a group of medications called corticosteroids. Corticosteroids are hormones that are produced naturally in our body, and necessary for many important bodily functions.
Methylprednisolone is a synthetic (man-made) corticosteroid medication that has been developed to imitate the actions of naturally occurring corticosteroid hormones in the body. A particularly important action of methlyprednisolone is to relieve inflammation that causes symptoms such as swelling, itching, and redness.
Symptoms of inflammation are often seen with allergic reactions such as severe allergic skin reactions, reactions to insect bites, and anaphylaxis (a severe, life-threatening allergic reaction). Other conditions and symptoms associated with inflammation can also be treated with corticosteroids. These include painful swollen joints caused by arthritis, and relief of asthma symptoms caused by inflamed breathing passages.
Methylprednisolone may also be used by people who are not able to produce enough of their own corticosteroid naturally (e.g., Addison's disease). Additional conditions that may be treated with methylprednisolone include severe skin conditions (e.g., psoriasis), certain eye conditions, ulcerative colitis, certain blood disorders, leukemia, lupus, and multiple sclerosis.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Blood clots: This medication may increase the chance of blood clot formation, causing a reduction of blood flow to the organs or extremities.
If you have a history of clotting you may be at increased risk of experiencing blood clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg. If you experience symptoms such as sharp pain and swelling in the leg, difficulty breathing, chest pain, blurred vision, or difficulty speaking, contact your doctor immediately.
Depression: Corticosteroids have been known to cause mood swings and symptoms of depression. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.
Diabetes: Methylprednisolone may cause a loss of control of diabetes by increasing blood glucose (sugar). If you have diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. You may need to check your blood glucose levels more often.
Eye problems: Prolonged use of methylprednisolone may cause glaucoma with possible damage to the optic nerves or it may produce cataracts. It may also increase the risk of eye infections due to fungi or viruses. Report any change in vision, eye pain, eye irritation, redness, or discharge to your doctor as soon as possible.
Fluid and electrolyte balance: This medication may cause electrolyte imbalances (changes in the levels of certain salts in the blood). If you notice dry mouth, thirst, weakness, fatigue, muscle pain and cramps, fast heartbeat, or decreased urination, see your doctor.
Heart disease: Methylprednisolone may cause an elevation of blood pressure, salt and water retention, and increased excretion of potassium. People with heart disease should be monitored by their doctor while taking this medication. People with heart disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infections: Corticosteroids can reduce your body's ability to fight infections and may hide signs of infection that is developing. If you have had tuberculosis in the past, methylprednisolone may cause the infection to return. If you experience signs of infection such as sore throat, fever, sneezing, or coughing, contact your doctor as soon as possible.
Kidney disease: Methylprednisolone may not clear from the body at the expected rate in cases where the kidney is not working properly. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Methylprednisolone may not clear from the body at the expected rate in cases where the liver is not working properly. If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Methylprednisolone may also cause harm to the liver. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Myasthenia gravis: Myasthenia gravis is a condition that causes specific muscle weakness. Methylprednisolone can cause muscle wasting or decreasing muscle. If you have myasthenia gravis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Ocular herpes simplex: People who have the herpes simplex virus affecting their eye should be monitored by their doctor while taking methylprednisolone, as the medication may cause damage to the cornea.
Osteoporosis (bone disease): Methylprednisolone causes the body to lose calcium and may cause osteoporosis to develop or worsen. If you have osteoporosis or are at risk of developing osteoporosis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pancreatitis: Corticosteroids can cause the pancreas to become inflamed. Report signs of pancreatitis such as abdominal pain on the upper left side, back pain, nausea, fever, chills, rapid heartbeat, or swollen abdomen to your doctor immediately.
Skin test injection: Methylprednisolone, like other corticosteroids, can cause false negative test results (i.e., tuberculosis or allergy) by reducing the body's reaction to the test serum.
Stomach ulcer: Methylprednisolone may cause stomach ulcers to worsen or develop. If you have stomach problems or a history of stomach problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Stress: A dosage adjustment of methylprednisolone may be required for anyone subjected to unusual stress.
Underactive thyroid (hypothyroidism): Methylprednisolone may not clear from the body at the expected rate when a person is hypothyroid. As a result, the effects of the medication may be increased. If you have hypothyroidism, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vaccines: People receiving immunosuppressive doses of corticosteroids should not receive live or live-attenuated (modified) vaccines, as there is a risk of infection and poor immune response to the vaccine.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are breast-feeding and are taking methylprednisolone, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding
Children: The active ingredient in this medication, methylprednisolone, belongs to the family of medications known as corticosteroids. Children may be more likely to experience the side effects encountered by using this class of medication for long periods of time (e.g., slowing down of growth, delayed weight gain). The use of this medication by children should be limited to the smallest dose that will be effective. Discuss with your doctor the risks and benefits of the use of this medication for children.
