Exelon® (Rivastigmine Tartrate) — Patient Information
Exelon® is a medicine used to help manage symptoms of certain types of dementia. It contains rivastigmine tartrate, a cholinesterase inhibitor that works by increasing levels of a brain chemical involved in memory and thinking.
This page is written to be patient-friendly and practical. It outlines how Exelon works, typical uses, how to take it, common safety considerations, and what to expect in everyday life—particularly for people living in Australia.

How Exelon works (mechanism of action)
In the brain, a chemical messenger called acetylcholine supports functions such as memory, attention and learning. In Alzheimer’s disease and some related dementias, acetylcholine levels tend to be lower.
Rivastigmine works by inhibiting cholinesterase enzymes (including acetylcholinesterase and butyrylcholinesterase). This helps reduce the breakdown of acetylcholine, leading to higher acetylcholine activity in the brain.
Important: Exelon does not cure dementia. Instead, it may help maintain or slow the worsening of symptoms for some people, especially in the earlier stages.
What conditions is Exelon used for?
Indications (typical clinical uses)
- Alzheimer’s disease—to help manage symptoms in mild to moderate stages in many patients.
- Parkinson’s disease dementia—to help manage symptoms in some people with dementia associated with Parkinson’s disease.
- Other dementias related to cholinergic deficit—depending on local product indications and formulation availability.
Always check the information provided with your specific Exelon product pack, as indications and dosing can vary slightly by formulation and local regulatory updates.
Pharmacokinetics (how the body handles rivastigmine)
Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised and eliminated.
- Absorption: After taking rivastigmine by mouth, it is absorbed into the bloodstream. Absorption is generally influenced by food timing.
- Distribution: Rivastigmine distributes throughout the body, including the central nervous system.
- Metabolism: Rivastigmine is metabolised mainly by esterases (enzymes that process certain chemical groups), rather than primarily by liver pathways typical of many other drugs. This may reduce the likelihood of some drug–drug metabolism interactions, though interactions can still occur.
- Elimination: Metabolites are eliminated primarily via the kidneys and partly through other routes.
- Onset and peak effect: The medicine’s effect is related to sustained cholinesterase inhibition. Symptom benefit may take weeks to become noticeable.
When to take Exelon: timing and consistency
Consistency is important. Set a routine that you can stick to daily.
General timing tips
- Take it at the same times each day (unless your prescriber advises otherwise).
- Use a dose schedule you can follow—especially if the medicine is taken twice daily.
- If doses are missed: refer to the instructions on your product label and your healthcare professional’s advice. Do not “double up” unless specifically instructed.
Practical expectation: Early in treatment, side effects are more likely. Dose increases are usually gradual to improve tolerability.
Food interactions: can you take Exelon with meals?
Food can affect tolerance and absorption for some people, particularly with oral dosing.
- Oral formulations: Many people tolerate rivastigmine better when taken with food. If you experience nausea or stomach upset, taking it after meals may help.
- Consistency matters: If your instructions allow taking with food, aim for similar meal timing each day.
- Patch formulations (if applicable): Food timing is not typically a factor for patch delivery.
Tip: If nausea occurs, try taking the dose with a meal or immediately after (as advised on your pack) rather than on an empty stomach.
Alcohol interactions
Alcohol can worsen side effects that may already occur with rivastigmine, such as:
- Dizziness
- Indigestion or nausea
- Sleepiness or impaired coordination
While a direct biochemical interaction may not be the main concern, combining alcohol with Exelon can increase the risk of feeling unwell, dehydrated, or less steady on your feet—especially in older adults.
General advice: Limit alcohol and discuss your specific situation with a healthcare professional. If you notice increased nausea, vomiting, faintness or falls after drinking, avoid alcohol and seek advice.
Interactions with other medicines
Tell your doctor or pharmacist about all medicines and supplements you take, including:
- Prescribed medicines
- Pharmacy medicines
- Herbal products and vitamins
- Over-the-counter cold/flu remedies
Medicines that may be relevant
- Anticholinergic medicines (used for some bladder conditions, allergies or movement disorders): These can work against cholinesterase inhibitors. This may reduce Exelon’s effect.
- Other cholinergic agents: Combined use may increase gastrointestinal side effects or muscle cramps.
- Medicines that affect heart rate (e.g., some types of beta-blockers or other rate-slowing drugs): Exelon may contribute to bradycardia (slow heart rate) in susceptible individuals.
- Medicines that cause nausea or vomiting: Side effects may become more noticeable when used together.
Always check: Drug interactions can depend on your age, other conditions, and the exact Exelon formulation. Your pharmacist can help check interactions before you start or change doses.
Dosing: how much is taken and how it’s adjusted
Dosing is typically started at a low dose and increased gradually to improve tolerability. The exact strength, frequency and maximum dose depend on the form of Exelon and individual response.
General dosing principles
- Start low to reduce side effects such as nausea and dizziness.
- Increase stepwise if tolerated.
- Adjust for tolerability—if side effects occur, your healthcare professional may slow down the dose increase or reduce the dose.
- Do not change the dose without professional advice.
Typical oral approach (illustrative)
Many oral rivastigmine regimens are dosed twice daily with gradual escalation. Because strengths differ and pack instructions vary, use the schedule provided with your specific Exelon product.
Patch approach (if applicable): Patch strengths are usually changed periodically according to the product schedule. If using a patch product, follow the label for correct application and timing.
Missed dose guidance: If you miss a dose, follow your product’s directions or ask your pharmacist. Restarting after a longer gap may require dose retitration.
Safety profile: common and serious side effects
Like all medicines, Exelon can cause side effects. Many are mild to moderate, especially early on. People vary widely in their sensitivity.
Common side effects
- Nausea
- Vomiting
- Diarrhoea
- Loss of appetite or weight loss
- Dizziness
- Headache
- Fatigue
Less common but important effects
- Slow heart rate (bradycardia)
- Fainting or near-fainting
- Dehydration especially if vomiting or diarrhoea occurs

Monitoring tip: If you or the person taking Exelon is experiencing new dizziness, falls, or significant appetite/weight changes, contact a healthcare professional promptly.
Practical use tips for day-to-day success
1) Help reduce nausea and stomach upset
- Take oral doses with food if your product instructions allow and if nausea occurs.
- Stay hydrated, especially if diarrhoea occurs.
- Eat smaller meals more often if appetite is reduced.
2) Watch for dizziness and falls risk
- Stand up slowly and ensure good lighting at night.
- Be cautious with driving or operating machinery if you feel unsteady.
- Inform your clinician if dizziness increases after starting or increasing the dose.
3) Use reminders
- Set alarms on a phone or medication reminder device.
- Use a dosette (pill organiser) if you take tablets/capsules and your regimen supports it.
4) Keep track of benefits and tolerability
Symptom changes may be subtle. Consider monitoring:
- Day-to-day functioning (memory support, routine tasks)
- Behaviour or mood changes
- Side effects such as nausea or weight loss
Alternative options
Depending on the type and stage of dementia, other treatments may be considered. These options may include:
- Other cholinesterase inhibitors (e.g., donepezil, galantamine) for some forms of dementia.
- Memantine (a treatment that works differently and may be used in some moderate to severe cases, sometimes in combination—this depends on individual assessment).
- Non-medicine supports such as cognitive stimulation, caregiver support, routine-based strategies, and managing hearing/vision problems.
If Exelon causes intolerable side effects, a healthcare professional may discuss an alternative medicine or formulation (such as switching from oral to patch, if appropriate) to improve tolerability.
