What is corticotropin?

Corticotropin is a hormone that treats various inflammatory and immune conditions, including psoriasis, Stevens-Johnson syndrome, psoriatic or rheumatoid arthritis, ankylosing spondylitis, lupus, polymyositis, severe allergic reactions, symptomatic sarcoidosis, and inflammatory conditions of the eyes.

Corticotropin is also used for acute episodes of multiple sclerosis in adults.

Some corticotropin products are for treating infantile spasms in children under 2 years old. The prefilled injector is not for treating infantile spasms.

Corticotropin can help reduce symptoms of an illness, but it does not cure these conditions.

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

How should I use corticotropin?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Your doctor will perform tests to make sure corticotropin is the right treatment for you.

Corticotropin may be injected into a muscle or under the skin, depending on the product prescribed for you. Some prefilled products are for injection under the skin only. A healthcare provider may give you this injection or may teach you how to properly use this medicine by yourself.

The prefilled injector is for adults 18 years and older and is injected under the skin only.

Prepare an injection only when you are ready to give it. Call your pharmacist if the medicine looks cloudy, has changed colors or has particles in it.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.

Your dose needs may change during times of stress, serious illness, surgery or medical emergency. Do not change your dose, dosing schedule, or stop using corticotropin suddenly without your doctor's advice. Follow your doctor's instructions about tapering your dose.

Dosing for certain indications is based on body surface area (height and weight) in children under 2 years old. Your child's dose may change if the child gains or loses weight or if they are still growing.

Call your doctor if your symptoms do not improve, or if they get worse.

You may need frequent medical tests, and your doctor will need to check your progress on a regular basis.

Store this medicine in the refrigerator. Protect from light, heat and do not freeze. You may store a prefilled injector at room temperature for up to 24 hours. Do not warm the medicine with hot water, sunlight, or a microwave.

Take the prefilled injector out of the refrigerator and let it reach room temperature for 45 minutes before using. Do not leave the medicine out for longer than 24 hours.

Throw away a prefilled injector after one use, even if there is still medicine left inside. Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.
