If you or a loved one have been prescribed rivastigmine, you probably have a lot of questions. This short guide breaks down the basics in plain language so you can feel confident about taking it.
Rivastigmine belongs to a class called cholinesterase inhibitors. In simple terms, it stops an enzyme from breaking down acetylcholine – a brain chemical that helps with memory and thinking. By keeping more of this chemical around, the drug can slow the decline in mental function caused by Alzheimer’s disease or Parkinson’s‑related dementia.
The medication comes as oral capsules, liquid solution, and a skin patch. Capsules usually start at 1.5 mg twice daily; your doctor may raise the dose every two weeks up to 6 mg twice daily if you tolerate it well. The liquid works similarly but lets you fine‑tune the amount more easily for people who have trouble swallowing.
The patch is a once‑daily option that delivers a steady dose over 24 hours. It starts at 4.6 mg/24 h and can be increased to 9.5 mg/24 h. Many users prefer the patch because it avoids stomach upset that pills sometimes cause.
Like any medication, rivastigmine has side effects. The most frequent ones are nausea, vomiting, loss of appetite, and weight loss. Some people also notice dizziness or a mild headache. If you get severe stomach pain, uncontrolled diarrhea, or signs of an allergic reaction (rash, swelling, trouble breathing), call your doctor right away.
Because the drug can affect heart rhythm in rare cases, anyone with existing heart problems should discuss risks with their physician before starting treatment.
If you notice persistent vomiting, severe dizziness, fainting, or a rapid change in mood or behavior, reach out promptly. These could signal that the dose is too high or that an underlying issue needs attention.
Regular check‑ins with your doctor are key. They’ll likely run simple blood tests and assess cognitive function every few months to see if the drug is still helping.
Rivastigmine can be a useful tool for slowing dementia symptoms, but it works best when you understand how to use it correctly. Stick to the prescribed dose, monitor side effects, and keep open communication with your healthcare team. With those steps, you’ll get the most benefit while minimizing discomfort.
