About Reminyl

What Reminyl is used for

REMINYL/REMINYL ER is used to treat the symptoms of mild to moderate Alzheimer’s disease (a type of dementia), a disease that alters brain function. The symptoms include progressive memory loss, increasing confusion and behavioural changes, as a result of which it becomes more and more difficult to carry out the activities of daily living.

What Reminyl does

This medication is one of a group of drugs called “cholinesterase inhibitors” which are used to treat the symptoms of mild to moderate Alzheimer’s disease. Dementia due to Alzheimer’s disease is believed to be related to lack of a substance in the brain called acetylcholine, a substance which is thought to be necessary for good brain function. REMINYL/REMINYL ER increases the amount of this substance in the brain, improving memory.
