• episodes of symptoms in people who have multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control);
• episodes of symptoms in people who have rheumatoid arthritis (a condition in which the body attacks its own joints, causing pain, swelling, and loss of function);

Corticotropin repository injection is in a class of medications called hormones. It treats many conditions by decreasing the activity of the immune system so that it will not cause damage to the organs. There is not enough information to tell how corticotropin repository injection works to treat infantile spasms.

HOW should this medicine be used?

Corticotropin repository injection comes as a long acting gel to inject subcutaneously (under the skin) or intramuscularly (into a muscle). When corticotropin repository injection is used to treat infantile spasms, it is usually injected into a muscle twice a day for two weeks and then injected on a gradually decreasing schedule for another two weeks. When corticotropin repository injection is used to treat multiple sclerosis, it is usually injected once a day for 2 to 3 weeks, and then the dose is gradually decreased. When corticotropin repository injection is used to treat other conditions, it is injected once every 24 to 72 hours, depending on the condition being treated and how well the medication works to treat the condition. Inject corticotropin repository injection at around the same time(s) of day on every day that you are told to inject it. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use corticotropin repository injection exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Continue to use corticotropin repository injection as long as it has been prescribed by your doctor. Do not stop using corticotropin repository injection without talking to your doctor. If you suddenly stop using corticotropin repository injection, you may experience symptoms such as weakness, tiredness, pale skin, changes in skin color, weight loss, stomach pain, and loss of appetite. Your doctor will probably decrease your dose gradually.

You can inject corticotropin repository injection yourself or have a relative or friend inject the medication. You or the person who will be performing the injections should read the manufacturer's directions for injecting the medication before you inject it for the first time at home. Your doctor will show you or the person who will be injecting the medication how to perform the injections, or your doctor can arrange for a nurse to come to your home to show you how to inject the medication.

Corticotropin repository injection comes as a vial where you will use a syringe to withdraw the prescribed dose before injecting or as an autoinjector (prefilled syringe). Ask your doctor which type of needle and syringe you should use to inject corticotropin repository injection from the vial. Do not share needles or syringes or use them more than once. Dispose of used needles and syringes in a puncture-proof container. Ask your doctor or pharmacist how to dispose of the puncture-proof container.

If you are injecting corticotropin repository injection under your skin, you can inject it anywhere in your upper thigh, upper arm, or stomach area except for your navel (belly button) and the 1 inch area around it. If you are injecting corticotropin repository injection into a muscle, you can inject it anywhere on your upper arm or upper outer thigh. If you are giving the injection to a baby you should inject it into the upper outer thigh. Choose a new spot at least 1 inch away from a spot where you have already injected the medication each time you inject it. Do not inject the medication into any area that is red, swollen, painful, hard, or sensitive, or that has tattoos, warts, scars, or birthmarks. Do not inject the medication into your knee or groin areas.

If using the vial to inject your corticotropin repository injection, follow these directions to give the dose:

• Look at the vial of corticotropin repository injection before you prepare your dose. Be sure that the vial is labeled with the correct name of the medication and an expiration date that has not passed.
• The medication in the vial should be clear and colorless and should not be cloudy or contain flecks or particles. If you do not have the right medication, if your medication is expired, or if it does not look as it should, call your pharmacist and do not use that vial.
• Allow your medication to warm to room temperature before you inject it. You can warm the medication by rolling the vial between your hands or holding it under your arm for a few minutes.

If using the autoinjector to administer corticotropin repository injection, remove the autoinjector from the refrigerator and allow to warm to room temperature for 45 minutes before injecting. Corticotropin repository autoinjector is only for subcutaneous injection. Rotate area or site for each injection and do not use the same site more than one time per week.

Read the directions that come with the autoinjector and make sure you understand how to inject it.

If you are giving corticotropin repository injection to your child, you can hold your child on your lap or have your child lie flat while you are giving the injection. You may find it helpful to have someone else hold the child in position or distract the child with a noisy toy while you are injecting the medication. You can help decrease your child's pain by placing an ice cube on the spot where you will inject the medication before or after the injection.

If you are giving corticotropin repository injection to your child to treat infantile spasms, your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when your child begins treatment with corticotropin repository injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
