Why is this medication prescribed?
Methylprednisolone injection is used to treat severe allergic reactions. Methylprednisolone injection is used in the management of multiple sclerosis (a disease in which the nerves do not function properly), lupus (a disease in which the body attacks many of its own organs), gastrointestinal disease, and certain types of arthritis. Methylprednisolone injection is also used to treat certain conditions that affect the blood, skin, eyes, nervous system, thyroid, kidneys, and lungs. It is sometimes used in combination with other medications to treat symptoms of low corticosteroid levels (lack of certain substances that are usually produced by the body and are needed for normal body functioning). Methylprednisolone injection is in a class of medications called corticosteroids. It works to treat people with low levels of corticosteroids by replacing steroids that are normally produced naturally by the body. It also works to treat other conditions by reducing swelling and redness and by changing the way the immune system works.
How should this medicine be used?
Methylprednisolone injection comes as powder to be mixed with liquid to be injected intramuscularly (into a muscle) or intravenously (into a vein). It also comes as a suspension for injection to be injected intramuscularly, intra-articularly (into a joint), or intralesionally (into a lesion). Your personal dosing schedule will depend on your condition and on how you respond to treatment.
You may receive methylprednisolone injection in a hospital or medical facility, or you may be given the medication to use at home. If you will be using methylprednisolone injection at home, your healthcare provider will show you how to inject the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions. Ask your healthcare provider what to do if you have any problems using methylprednisolone injection.
Your doctor may change your dose of methylprednisolone injection during your treatment to be sure that you are always using the lowest dose that works for you. Your doctor may also need to change your dose if you experience unusual stress on your body such as surgery, illness, or infection. Tell your doctor if your symptoms improve or get worse or if you get sick or have any changes in your health during your treatment.
