Important Safety Information
What is the most important information I should know about H.P. Acthar Gel?
Acthar can cause serious side effects, including:
- Increased risk of infections. Acthar may affect your immune system. Therefore, patients may be more likely to get new infections, or inactive infections may become active. Tell your doctor right away if you have any signs of infection, such as fever, cough, vomiting, diarrhea; or sign of illness or flu; or any open cuts or sores.
- Adrenal gland changes. Acthar has effects on the adrenal gland. When a patient is taking Acthar, their adrenal gland may produce too much of a hormone called cortisol. This can cause symptoms of Cushing’s syndrome (upper body fat, rounded face, thin skin), which is more common in patients who take this medicine for a long time. When a patient stops taking Acthar after a long time, the body may not produce enough cortisol on its own (adrenal insufficiency). The doctor may prescribe a steroid medicine to protect the body until the adrenal gland recovers. Tell your doctor right away if you experience weight loss, feel weak or tired, have stomach pain or develop a fever. Do not stop administering Acthar without talking to your doctor first.
- Blood pressure changes. Acthar may cause an increase in blood pressure. Blood pressure should be checked during treatment.
- Increased amount of water in the body, increased body salts, and low potassium in the blood. Acthar may cause your body to have increased amount of body salts and water that stays in the body, and may lower the amount of potassium in the blood. Your doctor may instruct you to make some dietary changes.
- Vaccine eligibility. Patients should not receive certain vaccines during Acthar treatment. Talk to your doctor about which vaccines are safe for you.
- Undetectable conditions. Acthar may hide (or mask) symptoms of other conditions or diseases, making it more difficult for your doctor to diagnose other conditions or diseases in you during treatment.
- Stomach bleeding or ulcers. You may have an increased risk for bleeding from the stomach or having a stomach ulcer. Report any pain in the stomach area, vomiting or bloody vomit, bloody or black stools, excessive tiredness, increased thirst, difficulty breathing or increased heart rate.
- Changes in mood or behavior. Irritability, depression, or trouble sleeping may occur.
