What is Cortrophin Gel (corticotropin) used for?

How Cortrophin Gel (corticotropin) works

Cortrophin Gel (corticotropin) is a mix of adrenocorticotropic hormone (ACTH) analogs and similar proteins. This mixture works like the natural ACTH that your body makes.

Cortrophin Gel (corticotropin) helps the adrenal gland release steroid hormones like cortisol into the body. These steroid hormones help reduce inflammation. They also lower the activity of the immune system. This can help treat some autoimmune and inflammatory conditions.

Pharmacist tips for Cortrophin Gel (corticotropin)

pharmacist
  • Cortrophin Gel (corticotropin) can raise your risk of a serious infection. Call your primary care provider if you have signs of an infection, like fever, weakness, sweating, chills, cough, difficulty breathing, or diarrhea, while you're taking this medication. You might have to stop taking Cortrophin Gel (corticotropin) so your body can fight the infection as best as it can.

    • Before getting any vaccines, tell the healthcare professional that you're taking Cortrophin Gel (corticotropin). Ask your care team if you're not sure whether you can get the vaccine you want. You might need to avoid certain vaccines, like the smallpox vaccine or other live vaccines. It's not known how Cortrophin Gel (corticotropin) affects your body's response to vaccines.

      • Don't lower your dose or stop taking Cortrophin Gel (corticotropin) suddenly without talking to your prescriber first. Otherwise, you might have withdrawal symptoms like weakness, body aches, and stomach pain. Work with your care team to see how to safely lower your dose or stop the medication.

        • Make sure your care team knows about all your medical conditions. Some health conditions, like thyroid problems and liver cirrhosis) can cause Cortrophin Gel (corticotropin) to have a stronger effect. Other conditions, like diabetes, myasthenia gravis, and kidney problems, can get worse during treatment.

          • Keep the vials of Cortrophin Gel (corticotropin) in the refrigerator. For the 1 mL vials, they're good for 6 months after you first use the vial. For the 5 mL vials, they're good for 28 days after you first use the vial. If the expiration date on the vial is sooner than these time frames, throw away the vials on the expiration date.

            • Your healthcare team will give you training on how to draw up your dose into a syringe and inject Cortrophin Gel (corticotropin). Your prescriber will tell you what needle sizes to use to draw up the dose and inject the medication. Ask your care team if you have any questions on how to prepare and inject the medication.

              • Before you draw up your dose, roll the Cortrophin Gel (corticotropin) vial between your hands for a few minutes to warm the medication up. The medication turns into a solid gel in the refrigerator. But it should become liquid after it's warmed up. Don't microwave or use the stove to warm up the medication.

                • For injections under the skin: Inject Cortrophin Gel (corticotropin) into the fatty part under the skin either on top of your thigh or your stomach (at least 1 inch from the belly button). You can also ask someone to inject the medication into the fatty part under the skin on the side or at the back of your upper arm. Pinch the skin, insert the needle at a 45º angle, and push down on the plunger to inject the medication.

                  • For injections into a muscle: Inject Cortrophin Gel (corticotropin) into the muscle of your upper-outer thigh. Someone can also help inject the medication into the muscle of your upper arm. Hold the skin where you're going to inject. Then, insert the needle at a 90º angle and push down on the plunger to inject the medication. Never inject into a vein.

                    • Choose a different spot each time you inject Cortrophin Gel (corticotropin) to prevent skin irritation. Make sure there's at least an inch between the areas where you inject the medication. Use the injection calendar to write down where you injected the medication each time.

                      • Once you're done with your injection, put the Cortrophin Gel (corticotropin) vial back into the refrigerator. Throw away the used needle and syringe in a sharps container or heavy-duty plastic container, like an empty laundry detergent bottle. This helps lower the risk of needle-stick injuries. Don't throw them away in your trash can. Visit the FDA's website for information about throwing away your sharps container safely.

                        Frequently asked questions about Cortrophin Gel (corticotropin)

                        Is Cortrophin Gel (corticotropin) a steroid?
                        No, Cortrophin Gel (corticotropin) isn't a steroid. But it's thought that the medication helps the body release cortisol, which is a type of steroid hormone.
                        What is Cortrophin Gel (corticotropin) used for?
                        Cortrophin Gel (corticotropin) is used to treat different health problems that are caused by inflammation in the body. It can help with flare-ups of conditions like rheumatoid arthritis, psoriasis, multiple sclerosis, and Stevens-Johnson syndrome. It can also help keep inflammation low over a long period of time. Ask your prescriber if this medication is a good option for you if you have an inflammatory condition.
                        What's the difference between Cortrophin Gel and Acthar Gel?
                        Cortrophin Gel and Acthar Gel both contain a natural form of the adrenocorticotropic hormone (ACTH) from pigs called corticotropin. They're both injectable medications that treat similar conditions. But Acthar Gel is also approved for treating seizures in babies (infantile spasms) whereas Cortrophin Gel isn't. In addition, both medications come in vials, which means you have to draw the dose up into a syringe. But Acthar Gel also comes in a prefilled injector, which makes it easier to use. Talk to your prescriber to compare between Cortrophin Gel and Acthar Gel.
                        Can Cortrophin Gel (corticotropin) cause withdrawal symptoms?
                        Yes, you can have withdrawal symptoms with Cortrophin Gel (corticotropin). It's similar to withdrawal from corticosteroids. Withdrawal is more likely to happen if you lower your dose or stop taking Cortrophin Gel (corticotropin) suddenly after using it for a long time. Cortrophin Gel (corticotropin) makes your body release more cortisol, a steroid hormone. When you stop or lower the dose too quickly, your body needs time to start making cortisol on its own again. During this time, you can have symptoms like weakness, tiredness, body aches, and low appetite. To prevent withdrawal symptoms, your prescriber will slowly lower your dose over time.

                        What are the risks and warnings for Cortrophin Gel (corticotropin)?

                        Cortrophin Gel (corticotropin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                        risk-warning

                        Infections

                        Cortrophin Gel (corticotropin) can make it harder for your body to fight infections. This raises your risk of serious bacterial, viral, or fungal infections. If you had tuberculosis (TB) in the past, it could come back while you're taking this medication. Your prescriber might recommend antibiotics or antivirals during treatment to help prevent infection.

                        Call your primary care provider or go to urgent care right away if you have signs of an infection, like fever, chills, and tiredness. Keep in mind that Cortrophin Gel (corticotropin) might hide some signs of infection. If you get sick, you might need to stop taking Cortrophin Gel (corticotropin) until you get better so your body can fight the infection.

                        risk-warning

                        Changes in adrenal gland function

                        • Risk factors: Taking Cortrophin Gel (corticotropin) for a long period of time | Stress (such as trauma, injury, or infection)

                          Cortrophin Gel (corticotropin) acts like the adrenocorticotropic hormone (ACTH) that your body naturally makes. When you take Cortrophin Gel (corticotropin) long term, your body releases more of a stress hormone called cortisol. This raises your risk of having symptoms of Cushing's syndrome (when you have too much cortisol in your body). Symptoms include swelling, weight gain, face roundness, and muscle weakness. Tell your care team if you notice these symptoms while you're taking Cortrophin Gel (corticotropin).

                          Cortrophin Gel (corticotropin) can also affect how much natural ACTH that your body releases. When you lower your dose or stop taking the medication suddenly after long-term use, your body can't make its own ACTH fast enough. This is especially true in physically stressful situations (e.g., injury, infection). It can lead to withdrawal symptoms, like low energy, tiredness, body aches, and stomach upset. Tell your care team if you want to take a lower dose or stop the medication. Your prescriber will slowly lower your dose over time.

                          risk-warning

                          Risk of stomach ulcers or stomach bleeding

                          • Risk factors: Stomach ulcers or bleeding | Taking other medications that can cause stomach damage at the same time | Drinking alcohol

                            Cortrophin Gel (corticotropin) can raise the risk of stomach damage, stomach ulcers and possibly stomach bleeding. Talk to your prescriber about your risk for stomach problems and what you can do to lessen this risk. Tell your care team if you have burning stomach pain that doesn't go away, a burning feeling in the chest, or acid reflux. These can be signs of a stomach ulcer. And get medical care right away if you have signs of stomach bleeding, like bloody or dark stools.

                            risk-warning

                            High blood pressure, swelling, and electrolyte problems

                            • Risk factors: Heart failure | High blood pressure | Kidney problems

                              Cortrophin Gel (corticotropin) can cause your body to hold onto more salt and water. This can lead to higher blood pressure and swelling. The medication can also cause your electrolyte levels to change, such as lower potassium levels and lower calcium levels. Talk to your prescriber if you have heart failure, high blood pressure, or kidney problems. These side effects can lead to complications for you.

                              risk-warning

                              Weakened bones

                              • Risk factors: Taking Cortrophin Gel (corticotropin) for a long period of time

                                Taking Cortrophin Gel (corticotropin) over a long period of time can lead to weakened bones and osteoporosis. This can raise the risk of breaking a bone (fracture), especially in older adults. Get medical help or go to urgent care if you think you broke a bone.

                                risk-warning

                                Slowed growth in children

                                • Risk factors: Taking Cortrophin Gel (corticotropin) for a longer period of time | Infants and young children

                                  Cortrophin Gel (corticotropin) can slow growth in children, especially if they need to take the medication for a long time. The care team will check your child's growth during treatment. Talk to the prescriber if you have any concerns about your child's growth and development.

                                  risk-warning

                                  Eye problems

                                  • Risk factors: Cataracts or glaucoma | Using Cortrophin Gel (corticotropin) for a long period of time

                                    Long-term use of Cortrophin Gel (corticotropin) can lead to a higher risk of cataracts, glaucoma, and certain eye infections. Don't take Cortrophin Gel (corticotropin) if you have a viral infection in the eye called herpes simplex because the medication might make it worse. Let your prescriber or optometrist know if you notice eye pain, blurry vision, or any other vision changes.

                                    risk-warning

                                    Changes in mood or behavior

                                    • Risk factors: History of mental health problems

                                      Cortrophin Gel (corticotropin) can cause changes in mood or behavior. They can include feeling extremely happy or depressed. You also might have trouble sleeping, mood swings, or personality changes. It can also make mental health problems worse if you already have them. Tell your prescriber right away if there are any unusual changes in your mood or behavior while you're taking Cortrophin Gel (corticotropin).

                                      risk-warning

                                      Serious allergic reaction

                                      • Risk factors: Allergy to pork-related products | Long-term use

                                        Although rare, people who took Cortrophin Gel (corticotropin) have had serious allergic reactions. Don't take Cortrophin Gel (corticotropin) if you have allergies to pork-related products because this medication contains proteins that come from pigs. Get medical help right away if you notice trouble breathing, swelling of the face or mouth, rash, or hives after you inject this medication. These can be signs of an allergic reaction.

                                        In general, your dose depends on what condition you’re using Cortrophin Gel (corticotropin) for and how severe your symptoms are. Your prescriber can adjust the dose based on how well you respond to treatment.
