What is rivastigmine?

Rivastigmine improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical called acetylcholine (ah see til KO leen). People with dementia usually have lower levels of this chemical, which is important for the processes of memory, thinking, and reasoning.

Rivastigmine is used to treat mild to moderate dementia caused by Alzheimer’s or Parkinson’s disease.

Rivastigmine may also be used for other purposes not listed in this medication guide.

  • a heart rhythm disorder such as "sick sinus syndrome" (slow heartbeats);
  • an enlarged prostate or urination problems;
  • epilepsy or other seizure disorder; or
  • asthma or obstructive pulmonary disease.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take rivastigmine.
