Exelon (Rivastigmine Tartrate) — Patient Information (Australia)
Exelon contains rivastigmine tartrate, a medicine used to help manage symptoms of certain dementias. It works by supporting chemical messaging in the brain associated with memory and thinking.
This information is designed to be helpful and patient-friendly. It does not replace advice from your doctor or pharmacist, and you should always follow the instructions on your prescription label and medicine packaging.

2) What Exelon is used for (indications)
Exelon is used to treat symptoms of the following conditions:
- Alzheimer’s disease (mild to moderate symptoms in many treatment plans; suitability depends on individual assessment)
- Dementia associated with Parkinson’s disease (commonly mild to moderate severity)
It may help improve or stabilise symptoms in some people, including memory, thinking, and everyday functioning. It does not cure dementia.
3) How Exelon works (mechanism of action)
Rivastigmine belongs to a group of medicines called cholinesterase inhibitors. In the brain, the chemical messenger acetylcholine supports learning, memory, and attention.
Normally, enzymes break down acetylcholine. Rivastigmine works by:
- Inhibiting cholinesterase enzymes (including acetylcholinesterase and butyrylcholinesterase), which reduces breakdown of acetylcholine
- Leading to higher acetylcholine availability at nerve synapses
This can improve the communication between nerve cells involved in cognition and daily activities.
4) Pharmacokinetics (how the body handles the medicine)
“Pharmacokinetics” describes how the body absorbs, distributes, metabolises, and eliminates a medicine.
- Absorption: Rivastigmine is absorbed after dosing. With oral forms (such as capsules), absorption may be affected by food (see food interactions below).
- Distribution: Rivastigmine distributes through the body and reaches the central nervous system.
- Metabolism: It is primarily metabolised in the body (including involvement of pathways related to cholinesterase enzymes), producing metabolites.
- Elimination: The metabolites are mainly excreted by the kidneys.
Because dosing often begins low and increases gradually, this helps improve tolerability—particularly for common side effects such as nausea and vomiting.
5) Typical timing and how to take Exelon
Timing depends on the formulation and dosing schedule you’ve been prescribed.
General timing principles
- Consistency: Try to take it at the same times each day.
- Start low, go slow: Many patients begin with a lower dose and increase gradually every few weeks if tolerated.
- Missed dose: If you miss a dose, do not double up. Follow your pharmacy/doctor’s guidance (or the package instructions) for what to do next.
With meals
Some people find side effects easier to manage when taking rivastigmine with food (details below).
Always follow your specific label instructions for meal timing and dose schedule.
6) Food interactions (including when to take it with meals)
Food can influence how oral rivastigmine is absorbed and can affect gastrointestinal side effects.
Common practical guidance:
- If you experience nausea, vomiting, or stomach upset, your pharmacist or doctor may advise taking your dose with food.
- If you were told to take it with meals, try to remain consistent so your dosing routine is stable.
Do not make major changes to your meal pattern without checking with your pharmacist, especially during dose increases.
7) Alcohol and medicine interactions
Alcohol
Alcohol may worsen dizziness, sedation, or nausea in some people—especially if you are already experiencing gastrointestinal side effects or light-headedness. Dementia care often involves additional medications, increasing the chance of side effects. Consider limiting alcohol and discuss suitability with your pharmacist or doctor.
Interactions with other medicines
Rivastigmine can interact with medicines that affect the nervous system or medications used for heart rhythm and gastrointestinal function.
- Other cholinesterase inhibitors: Using additional medicines in the same class may increase side effects.
- Anticholinergic medicines: These may reduce the effects of rivastigmine (for example, some bladder or bowel control medicines with anticholinergic activity). Ask your pharmacist if your medicines include such agents.
- Medicines affecting heart rate: Rivastigmine may cause bradycardia (slow heart rate) in some patients. Caution is needed if you take medicines that also slow heart rate (e.g., certain beta-blockers or some calcium-channel blockers).
- Medicines causing nausea/vomiting: Combination can make gastrointestinal side effects harder to manage.
- Other dementia-related drugs: Inform your prescriber/pharmacist about all dementia medications so a safe plan can be made.
Always provide a full list of medicines (including over-the-counter products and herbal preparations) to your pharmacist for interaction checking.
8) Dosing — how Exelon is commonly started and adjusted
Dose is individualised based on tolerability and response. Exelon is usually started at a low dose and increased gradually.
General dosing approach (capsules/oral forms)
- Initial phase: Low starting dose once or twice daily depending on the prescribed regimen.
- Titration: Dose is typically increased after a period of stable tolerability, often every few weeks.
- Maintenance: The dose that is tolerated is continued to support symptom management.
Because dosing schedules vary between formulations and strengths, the most accurate dosing information is the one provided on your medicine label and by your prescribing clinician.
If side effects occur
If you experience persistent nausea, vomiting, weight loss, fainting, or worsening dizziness, your prescriber may:
- Delay the next dose increase
- Reduce the dose temporarily
- Adjust the timing (often with food)
- Review other medicines that may contribute
Do not stop or restart without advice, especially if you have missed several doses—restarting may require re-titration.
9) Safety profile — side effects and when to seek help
Like all medicines, Exelon may cause side effects. Not everyone experiences them. Many side effects are more common during the early stages or after dose increases and may improve with time.
Common side effects
- Nausea
- Vomiting
- Diarrhoea
- Loss of appetite
- Dyspepsia (indigestion)
- Dizziness
- Headache
- Tiredness or weakness
- Weight loss in some patients
Less common but important side effects
- Slow heart rate (bradycardia), fainting, or feeling unusually light-headed
- Exacerbation of tremor or worsening of Parkinson’s-related symptoms in some individuals
- Dehydration (particularly if vomiting or diarrhoea is significant)
- Muscle cramps or increased sweating (reported in some cases)
Allergic reactions (seek urgent help)
Stop using Exelon and seek urgent medical attention if you develop signs of allergy such as:
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing or swallowing
- Severe rash or hives
When to contact a healthcare professional promptly
- Persistent vomiting or diarrhoea, or inability to keep fluids down
- Significant weight loss or reduced food intake
- Fainting, near-fainting, or a very slow pulse
- New or worsening confusion, agitation, or severe dizziness
10) Practical use tips (how to make treatment easier)
Support nausea and stomach upset
- Take with food if advised or if nausea occurs.
- Eat smaller meals more frequently if appetite is reduced.
- Stay hydrated, especially if you experience diarrhoea or vomiting.
- If symptoms appear after dose increases, contact your pharmacist/doctor—dose adjustment may be needed.
Monitor weight and general wellbeing
- Weigh regularly (for example, weekly or monthly depending on your care plan).
- Track appetite, energy levels, and bowel habits.
- Tell your clinician if weight loss is noticeable or rapid.
Watch for dizziness and falls
- Rivastigmine can cause dizziness. Rising slowly from a seated position may help.
- Prevent falls by ensuring good lighting, removing trip hazards, and using mobility aids if required.
Consistency and routine
- Use a medication organiser (pill box) where appropriate and safe.
- Set reminders if you or your carer manage dosing schedules.
- Keep a record of dose changes, start dates, and side effects.
Handling missed doses
If a dose is missed:
- Do not take a double dose to “catch up.”
- Follow the advice on the pack or from your pharmacy.
- If you miss multiple doses, restarting may require re-titration—check with your prescriber.
11) Alternative options for dementia care
Dementia treatment is individualised, and the best choice depends on the type and severity of dementia, other medical conditions, and tolerance to medicines.
Other medicines commonly considered
- Donepezil (another cholinesterase inhibitor)
- Galantamine (another cholinesterase inhibitor)
- Memantine (an NMDA receptor antagonist, often used in moderate to severe Alzheimer’s disease depending on clinical assessment)
Your doctor will decide whether one option is more suitable based on symptoms, side-effect risk, and formulation preferences.
Non-medicine support
- Cognitive stimulation and structured routines
- Speech therapy or occupational therapy where appropriate
- Support for carers and safety planning to reduce falls and medication errors
- Managing cardiovascular risk factors and overall health
12) Australia context: availability, reimbursement, and legal considerations
In Australia, dementia medicines such as rivastigmine are regulated through the national medicines framework. Availability may depend on the specific formulation (for example, oral capsules versus other forms where available) and supply.
- Medicines access: Availability in pharmacies may depend on stock and manufacturer supply.
- Care planning: Dementia treatment often involves GP/specialist review and ongoing monitoring of side effects and benefit.
- Safety monitoring: Clinicians may review heart rate, blood pressure, weight, hydration status, and tolerability—especially during dose titration.
Recent guidance (general): In Australia, dementia management guidelines emphasise person-centred care, reviewing ongoing benefit regularly, and managing side effects proactively. Clinicians typically reassess therapy after a period of treatment and may discontinue if there is no meaningful benefit or if harms outweigh benefits.

14) FAQ — Frequently asked questions
How long does Exelon take to work?
Some people notice changes over weeks, especially after the dose stabilises. Exelon is often titrated gradually, so effects and side effects may change during the first few months. Your clinician may assess benefit periodically and adjust the plan if needed.
Can I stop Exelon suddenly?
Do not stop or change your dose without medical advice. Stopping can lead to worsening symptoms in some people. If you miss doses or are considering stopping, speak with your pharmacist or prescriber for guidance.
What should I do if my relative or patient vomits after taking a dose?
Do not take another dose immediately. Ensure they stay hydrated if possible. Contact your pharmacist or doctor, especially if vomiting is persistent, there are signs of dehydration, or if fainting/dizziness occurs. Dose adjustment may be recommended.
Does Exelon interact with Parkinson’s disease medications?
Rivastigmine may be used in patients with Parkinson’s disease dementia alongside other Parkinson’s medications. However, tolerability varies. Tell your pharmacist about all medicines to check for interactions and overlapping side effects such as dizziness or changes in heart rate.
Is Exelon safe for older adults?
Older adults can use rivastigmine, but they may be more sensitive to side effects such as nausea, weight loss, dehydration, and dizziness. Clinicians typically start with low doses and monitor closely.
Can Exelon be taken with other dementia medicines?
Sometimes dementia medicines are combined, but not always. The safety and suitability depend on the specific medicines involved and the individual situation. Ask your pharmacist to review your medication list.
What if I have stomach problems like ulcers or severe reflux?
Tell your doctor and pharmacist about any history of stomach ulcers, bleeding, severe reflux, or bowel conditions. While Exelon is not specifically indicated for ulcers, gastrointestinal side effects may still require careful monitoring.
Should I avoid driving or operating machinery?
Some people experience dizziness or fatigue. If you feel unsteady or drowsy, avoid driving and dangerous activities. Discuss specific advice with your clinician.
Will Exelon help with behaviour changes?
Exelon primarily targets cognitive symptoms, but improvements or stabilisation in thinking and daily function may indirectly help behaviour in some patients. Behaviour changes still need broader assessment and support.
Are there any signs that I should call an ambulance?
Call emergency services immediately if there are signs of a severe allergic reaction (such as trouble breathing or significant swelling) or if someone faints, has severe confusion, or has symptoms that suggest a medical emergency.
Important: If you have questions about your specific dose, missed doses, timing with meals, or side effects, contact your pharmacist. For urgent medical concerns, seek immediate medical help.
