This Medication Guide provides information only about the use of H.P. Acthar Gel for the treatment of Infantile Spasms. If your doctor prescribes H.P. Acthar Gel for you or your child for any other reason, talk to your doctor for information about how this medicine is used to treat your medical condition.
Read this Medication Guide before your child receives H.P. Acthar Gel and each time you refill your child's prescription. There may be new information. This Medication Guide does not take the place of talking with your doctor about your child's medical condition or treatment.
What is the most important information I should know about H.P. ACTHAR GEL?
H.P. Acthar Gel can cause serious side effects including:
1. Increased risk of infections. H.P. Acthar Gel is a medicine that can affect your child's immune system. When your child is taking H.P. Acthar Gel, it can lower the ability of your child's immune system to fight infections. H.P. Acthar Gel may:
- make your child more likely to get new infections
- worsen an infection that your child already has
- cause an inactive infection to become active, such as tuberculosis (TB)
Before starting H.P. Acthar Gel, tell your doctor if your child has:
- an infection or signs of an infection, such as:
- other signs of illness or flu
- a family member with an infection or signs of an infection
While taking H.P. Acthar Gel, your child should:
- stay away from people who are sick or who have infections
- tell your doctor right away if your child has any sign of
infection such as:
- fever (but your child may not have a fever with an infection)
- diarrhea or
- other signs of illness or flu and
- any open cuts or sores on his or her body
2. Effects on the adrenal gland after stopping H.P. Acthar Gel.
When your child stops taking H.P. Acthar Gel, his or her body may not produce enough of a hormone called cortisol on its own (adrenal insufficiency). Your child may need to take steroid medicine to protect the body until the adrenal gland recovers and is working well again, especially to protect the body if they have surgery or trauma. Do not stop giving your child injections of H.P. Acthar Gel without talking to your doctor first. Your doctor will tell you when and how to slowly stop giving the injections to avoid serious side effects.
While slowly stopping your child's injections of H.P. Acthar Gel or after you stop giving the injections, call your doctor right away if your child has any of the following:
- appears weak
- loses weight or has a decrease in appetite
- appears tired or lacking energy
- appears pale
- has stomach pain
- appears sick or is with a fever
3. Effects on the adrenal gland while taking H.P. Acthar Gel
When your child is taking H.P. Acthar Gel, his or her adrenal gland may produce too much cortisol. This can cause symptoms of Cushing's syndrome. Cushing's syndrome is more common in children who take H.P. Acthar Gel for a long time.
Symptoms of Cushing's syndrome include:
- increased upper body fat around the neck, but not the arms and legs
- weight gain
- rounded or “moon” face
- thin skin, easy bruising, and stretch marks on thighs, belly and trunk
- slowed growth rates in children
- weak bones (osteoporosis)
While receiving treatment with H.P. Acthar Gel other side effects can happen that are like side effects that happen due to treatment with steroid medicines.
The risk of getting side effects may increase the longer your child is treated with H.P. Acthar Gel. Side effects may include:
- increased blood pressure. Your doctor may check your child's blood pressure during treatment. If your child's blood pressure increases, your doctor may talk with you about possible treatment choices.
- too much water in the body (water retention), increased amount of body salts, and low potassium in the blood. H.P. Acthar Gel may cause your child to have an increased amount of body salts and water that stays in the body, and may lower the amount of potassium in your child's blood. Follow your doctor's instructions about if you need to decrease your child's salt intake or if you need to feed your child foods high in potassium.
4. Your child should not receive certain vaccines during treatment with H.P. Acthar Gel. Your child may receive killed or inactivated vaccines while receiving H.P. Acthar Gel. Before your child receives any vaccines, talk to your doctor about which vaccines are safe for your child. Certain vaccines could cause your child to have serious side effects, or the vaccine may not be effective.
5. Hiding (masking) symptoms of other conditions or diseases. It may be more difficult for your doctor to diagnose other conditions or diseases in your child during treatment with H.P. Acthar Gel. During treatment and after treatment ends, tell your doctor if your child has:
- any signs or symptoms of infection. See number 1 of this section in the Medication Guide.
- changes in body weight
- bloody or black tarry stool
- stomach pain
- excessive tiredness
- increased thirst
- fast heart rate
- difficulty breathing
6. Stomach and intestinal problems. H.P. Acthar Gel may cause bleeding of the stomach or intestine. Your child has an increased risk for bleeding from the stomach or having a stomach ulcer. Tell your doctor if your child has any pain in the stomach area (abdominal pain), vomits blood, or has bloody or black stools.
7. Changes in mood and behavior. During treatment with H.P. Acthar Gel your child may be irritable, have rapid changes in his or her mood, be depressed, have other changes in his or her behavior, or have trouble sleeping.
Tell your doctor if your child has any of the side effects or symptoms listed above.
