Exelon (Rivastigmine Tartrate) – Patient-Friendly Guide (UK)

Exelon is a medicine containing rivastigmine tartrate, used to treat certain symptoms of Alzheimer’s disease and Parkinson’s disease dementia. It works by supporting brain signalling involved in memory and thinking.

This page explains what Exelon is, how it works, when and how it is taken, important safety information, common interactions, and practical tips—written for people in the United Kingdom.

Basic product information

• Active ingredient: Rivastigmine tartrate
• Brand name: Exelon
• What it’s used for: Symptoms of dementia in Alzheimer’s disease and Parkinson’s disease dementia
• Typical forms (UK): Oral capsules and transdermal patches are commonly available

How Exelon works (mechanism of action)

Exelon (rivastigmine) is a cholinesterase inhibitor. It increases levels of acetylcholine in the brain by slowing the breakdown of chemicals that support nerve-to-nerve communication.

Specifically, rivastigmine inhibits the enzymes acetylcholinesterase and butyrylcholinesterase. In conditions like Alzheimer’s disease and Parkinson’s disease dementia, these pathways are reduced, contributing to memory and thinking difficulties.

What it may help with

Exelon does not “cure” dementia, but it can help improve or stabilise symptoms for some people. Effects vary between individuals, and it may take time to notice benefits.

• Memory and thinking difficulties
• Everyday function and ability to cope
• Behavioural symptoms in some cases

Pharmacokinetics (how the body handles it)

Pharmacokinetics describes how the body absorbs, processes, and clears a medicine. Rivastigmine is processed differently depending on the formulation.

Oral capsules

• Absorption: Absorbed from the gastrointestinal tract.
• Onset: Effects are not immediate; symptom changes are typically assessed over weeks.
• Metabolism: Primarily metabolised in the body; it forms metabolites that are cleared.
• Elimination: Cleared by the body through metabolic pathways, with metabolites excreted mainly via urine.

Transdermal patches

• Absorption: Delivered steadily through the skin.
• Onset: Typically steadier, with fewer peaks and troughs compared with capsules.
• Metabolism and elimination: Similar overall metabolic principles, with clearance after systemic absorption.

Your prescriber and pharmacist will advise which formulation is most suitable, based on tolerability, side effects, and practical considerations (for example, swallowing difficulty or adherence support).

Typical use in the UK

Exelon is used in clinical practice across the UK for dementia syndromes associated with:

• Alzheimer’s disease (for symptoms of mild to moderate dementia; in some situations may be continued as disease progresses)
• Parkinson’s disease dementia (for symptoms of dementia related to Parkinson’s disease)

Indications (who it is for)

In the UK, Exelon is indicated for the treatment of dementia due to Alzheimer’s disease and dementia in Parkinson’s disease. Your diagnosis and severity guide whether Exelon is appropriate.

Dosing: how Exelon is usually started and adjusted

Dosing is individual and depends on tolerance. Doctors commonly use a gradual dose escalation to reduce side effects (especially nausea, vomiting, and appetite changes).

General principles (capsules)

• Start with a low dose
• Increase step-by-step at intervals if tolerated
• If side effects occur, dose may be reduced or paused before continuing

General principles (patches)

• Start with the lowest patch strength
• Increase at intervals if tolerated
• Follow patch rotation and site selection to prevent skin reactions

Important: Always use the dose and schedule specified for your product (capsules vs patch), and do not switch formulation without professional advice.

When to take Exelon (timing guidance)

Timing can affect how well you tolerate the medicine. Many people experience fewer stomach-related side effects when taking Exelon with food.

Oral capsules

• Often taken with meals to improve tolerability
• Split dosing is common (for example morning and evening), depending on the prescribed regimen

Transdermal patches

• Apply the patch to clean, dry skin and typically change it once daily
• Choose different patch sites (rotate areas) to reduce irritation
• If a patch falls off or is removed, contact your pharmacist for advice on what to do

Food interactions (what to know)

Oral capsules: Taking rivastigmine with food may help reduce gastrointestinal side effects such as nausea and vomiting. Some people also find appetite changes are easier to manage with regular meals.

Transdermal patches: Food does not directly affect patch absorption, but overall tolerability can still be influenced by your general health and eating patterns.

Practical tips for meals

• Eat smaller, more frequent meals if nausea occurs.
• Stay hydrated, especially if vomiting or reduced intake occurs.
• Report persistent loss of appetite or weight loss to a healthcare professional.

Alcohol and medicine interactions

Alcohol can worsen symptoms in dementia and may increase dizziness or drowsiness, depending on the person and other medicines. Rivastigmine can also affect the digestive system and may lead to faintness in some people.

While there is no single “universal” rule, it is generally sensible to:

• Limit alcohol and avoid binge drinking.
• Be cautious if you notice dizziness, weakness, or stomach upset after drinking.
• Tell your healthcare professional about regular alcohol use, especially if you take other medications affecting heart rhythm, blood pressure, or the stomach.

Medication interactions (including key categories)

Exelon can interact with other medicines because of its effect on the nervous system and because it may influence heart rate, blood pressure, and gastrointestinal function. Always keep your healthcare team informed of all medicines, including over-the-counter products and supplements.

Common interaction considerations

• Other medicines with cholinergic or anticholinergic activity: Effects can oppose each other. Your clinician/pharmacist will advise.
• Medicines that slow the heart rate (bradycardia): Caution may be needed, particularly if you take drugs that already lower heart rate.
• Medicines affecting digestion: If you take anti-nausea or stomach medicines, your pharmacist will advise on timing and appropriateness.
• Medicines for Alzheimer’s or dementia: There may be considerations if you’re also using other cognitive enhancers.

Safety profile: side effects and when to seek help

Like all medicines, Exelon can cause side effects. Many people experience mild or moderate effects when starting or increasing the dose, and some symptoms settle after stabilisation.

Common side effects

• Nausea
• Vomiting
• Diarrhoea or changes in bowel habits
• Loss of appetite
• Dizziness
• Headache
• Fatigue

Skin reactions (patches)

• Redness, itching, swelling, or rash at the patch site
• Rotate patch sites; avoid applying to irritated or broken skin

Less common but serious symptoms

Seek urgent medical attention (or call emergency services) if you experience any signs of a serious reaction, such as:

• Severe or persistent vomiting, leading to dehydration
• Fainting, marked dizziness, or very slow heart rate
• Allergic reaction (e.g., swelling of the face/lips, difficulty breathing, widespread rash)
• Blackouts or severe confusion beyond your usual baseline

Who should take extra care

• People with stomach ulcers or a history of significant gastric problems
• People with heart rhythm disorders, slow pulse, or frequent fainting
• People with difficulty eating or a history of weight loss
• People with asthma or conditions that may worsen with cholinergic effects

Practical use tips (making Exelon easier to take)

Tips for capsules

• Take with food if advised or if it helps your stomach.
• Stay consistent with dosing times to support steadier tolerability.
• Track side effects during dose increases; inform your pharmacist/clinician promptly.
• If nausea occurs, try bland foods and small meals; hydration is key.

Tips for patches

• Apply to clean, dry, hairless skin (avoid shaving immediately before application unless advised).
• Choose a different area each day (rotation).
• Wash hands after handling the patch.
• Dispose of used patches safely (as instructed in the patient information leaflet).
• Avoid exposing the patch to excessive heat (e.g., heat pads, saunas) unless instructed otherwise.

Adherence support

Dementia care often involves carers and routines. Consider using:

• Medication reminders (pill organiser, alarms)
• Clear schedules on the wall or in a care plan
• Regular review of side effects and benefits with your healthcare team

Alternative options (if Exelon isn’t suitable)

Depending on your diagnosis, severity, and tolerability, clinicians may consider other medicines for dementia. Examples (not an exhaustive list) may include:

• Other cholinesterase inhibitors used for Alzheimer’s disease (for example, donepezil or galantamine, where appropriate)
• Memantine for certain stages of dementia (often in combination with a cholinesterase inhibitor in some cases)
• Non-medicine support such as cognitive stimulation therapy, structured routines, and caregiver support

If side effects are difficult to manage or there is no expected benefit, your healthcare professional may adjust the dose, switch formulation, or consider alternatives.
