Exelon (Generic Rivastigmine): Complete Medication Guide
Key Takeaways
Rivastigmine is a cholinesterase inhibitor that helps improve memory and thinking in people with early to moderate Alzheimer's disease and Parkinson's disease dementia.
It comes as a capsule, liquid, or patch and is taken once or twice daily depending on the form.
Common side effects include nausea, vomiting, and diarrhea, especially when starting the medication.
This medication may slow cognitive decline but does not cure Alzheimer's disease or Parkinson's dementia.
Regular monitoring by your healthcare provider is essential to check how well the medication works and manage any side effects.
Exelon (Generic Rivastigmine) Overview
Rivastigmine, sold under the brand name Exelon, is a medication that belongs to a class of drugs called cholinesterase inhibitors. It works by increasing the levels of a chemical messenger in the brain called acetylcholine, which plays an important role in memory, attention, and thinking. This medication is primarily used to treat cognitive symptoms in people with early to moderate Alzheimer's disease and dementia related to Parkinson's disease.
When you take rivastigmine, it helps protect acetylcholine from breaking down too quickly in the brain. By maintaining higher levels of this chemical, the medication may help improve memory problems, confusion, and difficulty with thinking. However, it's important to understand that rivastigmine does not stop or reverse the underlying disease—it may help slow the progression of symptoms and improve quality of life for some people.
Your healthcare provider may recommend starting this medication if you've been diagnosed with mild to moderate cognitive impairment. The medication is available in several forms to make it easier to take as prescribed. This information is educational and does not replace advice from your healthcare provider.
Side Effects
Rivastigmine is generally well-tolerated by most people, though some may experience side effects, especially when first starting the medication or increasing the dose. Most side effects tend to improve over time as your body adjusts.
Common Side Effects
Nausea — One of the most frequent side effects, often worse on an empty stomach; eating food before taking the medication may help reduce this symptom.
Vomiting — May occur along with nausea, particularly during the first few weeks of treatment or dose increases.
Diarrhea — Changes in bowel movements are common and usually manageable with dietary adjustments and staying hydrated.
Loss of appetite — Some people notice they feel less hungry or eat smaller amounts while taking this medication.
Headache — Mild to moderate headaches may occur, usually temporary and manageable with over-the-counter pain relief options.
Dizziness — Feeling lightheaded or dizzy, especially when standing up quickly, may happen in some users.
Serious Side Effects
Severe nausea and vomiting — Persistent, uncontrollable vomiting that prevents you from keeping food or other medications down may require medical attention.
Fainting or severe dizziness — Loss of consciousness or severe lightheadedness could indicate a serious reaction requiring immediate care.
Slow heart rate — Rivastigmine may slow your heart rate; symptoms include extreme fatigue, shortness of breath, or chest discomfort.
Allergic reactions — Rash, swelling of the face or throat, or difficulty breathing are rare but require emergency care.
Gastrointestinal bleeding — Although uncommon, signs include vomiting blood or black, tarry stools and need urgent evaluation.
When to Seek Medical Attention
Contact your healthcare provider if you experience persistent nausea or vomiting that lasts more than a few days, severe dizziness that affects your daily activities, or any unusual changes in your heartbeat. If you develop signs of an allergic reaction such as rash, swelling, or difficulty breathing, seek emergency medical care immediately.

Important: Never stop taking rivastigmine without talking to your doctor first, as suddenly stopping the medication may cause your symptoms to return. If you miss a dose, take it as soon as you remember, unless it's almost time for your next dose—then skip the missed dose. Do not take double doses to make up for a missed one. Always take rivastigmine exactly as prescribed by your healthcare provider.
Drug Interactions
Rivastigmine may interact with other medications and substances. Some interactions can affect how well the medication works or increase the risk of side effects. It's important to tell your healthcare provider about all medications, supplements, and herbal products you're taking before starting rivastigmine.
Other Cholinesterase Inhibitors
Taking rivastigmine with other cholinergic medications (like donepezil or galantamine) can increase the risk of side effects such as nausea, vomiting, and slowed heart rate. Avoid combining these medications without your doctor's approval.
Anticholinergic Medications
Anticholinergic drugs (used to treat conditions like overactive bladder or Parkinson's) work opposite to rivastigmine and may reduce its effectiveness. Your doctor may need to adjust doses of one or both medications.
Certain Heart Medications
Beta-blockers and some other heart medications may interact with rivastigmine, potentially causing a slower heart rate or other cardiac effects. Regular monitoring may be necessary if you take both.
NSAIDs and Aspirin
Nonsteroidal anti-inflammatory drugs can increase the risk of gastrointestinal bleeding when combined with rivastigmine. Use these pain relievers cautiously and discuss alternatives with your healthcare provider.
Anesthetic Medications
If you need surgery, tell your anesthesiologist that you take rivastigmine, as it may interact with anesthesia and affect how your body responds during the procedure.
Succinylcholine
This muscle relaxant used during surgery can have prolonged effects when combined with rivastigmine. Inform all medical providers about your rivastigmine use before any procedure.

Frequently Asked Questions
Get answers to common questions about Exelon (generic rivastigmine).
Most people don't notice improvements immediately. It typically takes 4 to 6 weeks of consistent use at the therapeutic dose to see meaningful changes in memory or thinking. Your healthcare provider will monitor your progress during follow-up visits to determine if the medication is helping.
Yes, and it's actually recommended. Taking rivastigmine with food helps reduce nausea and stomach upset, which are common side effects. You can take it with a light snack or meal. Consistency helps—try taking it at the same time each day with food.
Tell your healthcare provider about persistent nausea right away. They may suggest taking the medication with food, adjusting your dose, or taking anti-nausea medication alongside rivastigmine. In some cases, switching from capsules to the patch form might help reduce gastrointestinal side effects.
The patch may cause fewer gastrointestinal side effects since it delivers medication through the skin rather than the stomach. However, some people develop skin irritation at the patch site. Your healthcare provider can help you decide which form is best for your situation based on your side effects and preferences.
Yes, NSAIDs like ibuprofen and naproxen can increase the risk of stomach bleeding when taken with rivastigmine. Acetaminophen (Tylenol) is generally a safer choice for pain relief. Always mention rivastigmine to your pharmacist before buying any over-the-counter medications to check for interactions.
