What is Aduhelm?
Aduhelm injection is used to reduce amyloid beta plaque, a protein found in the brain of people with Alzheimer's disease (a brain disease that slowly destroys the memory and ability to think, learn, communicate and handle daily activities).
Aduhelm is used to treat people with Alzheimer’s disease who have mild cognitive impairment (MCI) or mild dementia.
Aduhelm injection belongs to a class of medications called monoclonal antibodies. It works by blocking the formation of amyloid beta in the brain.
Aduhelm can cause temporary swelling or bleeding in the brain that usually clears up with time. This may cause no symptoms but can be serious. Call your doctor if you have headaches, dizziness, nausea, confusion, or vision changes.
To make sure Aduhelm is safe for you, tell your doctor if you:
- have ever had an allergic reaction to aducanumab, any other medications, or any of the ingredients in Aduhelm injection.
- take any other prescription or nonprescription medications, vitamins, nutritional supplements, and herbal products. Your doctor may need to change the doses of your medications or monitor you carefully for side effects; or
- have or have ever had any medical conditions.

Aduhelm can cause a condition called Amyloid Related Imaging Abnormalities or "ARIA."
ARIA is a temporary swelling or small spots of bleeding in the brain that usually clears up with time. Your doctor may perform an MRI of your brain before and during your treatment with Aduhelm. Ask your doctor about your risk.
