Acthar can cause side effects similar to those with steroid treatments. While taking Acthar, tell your doctor right away if you have any of the symptoms listed here:
- Increased risk of infections. You may be more likely to get new infections. Also, old infections may become active. Before and during treatment, tell your doctor if you see any signs of an infection. Contact your doctor at the first sign of an infection or fever. Signs of infection are fever, cough, vomiting, or diarrhea. Other signs may be flu or any open cuts or sores
Adrenal gland changes. When taking Acthar long term, your adrenal gland may produce too much of a hormone called cortisol, which may cause symptoms of Cushing’s syndrome, such as upper body fat, rounded “moon” face, bruising easily, or muscle weakness
Sometimes when you stop taking Acthar long term, your body may not produce enough cortisol on its own. This is called “adrenal insufficiency.” Your doctor may prescribe a steroid medicine to protect you until the adrenal gland recovers
- Increased blood pressure, body salt, and fluid levels. Your doctor may check your blood pressure while you are being treated with Acthar. He or she may recommend some changes to your diet, such as eating less salt and taking certain supplements
