Summary
Rivastigmine is used to treat mild to moderate Alzheimer's disease and Parkinson's disease dementia, which are conditions that affect memory and thinking abilities.
Rivastigmine works by inhibiting an enzyme called acetylcholinesterase, which breaks down acetylcholine, a brain chemical. This increases acetylcholine levels, helping improve memory and thinking.
Rivastigmine is usually taken as a capsule or patch. The starting dose is 1.5 mg twice daily, with a maximum of 6 mg twice daily, taken with food to reduce stomach upset.
Common side effects of rivastigmine include nausea, vomiting, and loss of appetite, which are unwanted reactions that occur in more than 10% of users.
Rivastigmine can cause gastrointestinal side effects like nausea and vomiting, which may lead to weight loss. It should not be used by those allergic to it or with severe liver problems.
