Before starting the Exelon Patch — a skin patch that delivers rivastigmine, a drug for Alzheimer's dementia — the most important questions to ask the prescriber are about the dose schedule, daily patch removal, skin reactions, heart and lung history, and what the drug can realistically achieve. According to the drug's DailyMed listing, rivastigmine is approved for mild, moderate, and severe Alzheimer's dementia and can improve thinking in some patients, but it does not cure the disease or stop it from progressing. That gap between "may help symptoms" and "will not change the course of the illness" is where realistic expectations start. The questions below help families weigh whether the patch fits the patient, and how to use it safely once treatment begins.

What should we expect this drug to actually do?
ask the prescriber to describe success in concrete terms. Rivastigmine is a cholinesterase inhibitor: it slows the breakdown of acetylcholine, a brain chemical involved in memory and attention. In some patients that means modest improvement in thinking or daily function; in others the benefit is holding steady for a while rather than getting better.
Ask how long the doctor will wait before judging whether the patch is helping, and what would prompt stopping it. Because the drug does not alter the underlying disease, decline will eventually continue even when the medication is working as intended. Knowing that in advance prevents the common misreading that the patch "stopped working" or "made things worse" when the disease itself progressed.
What is the dose schedule, and why does it start low?
Treatment begins with the smallest patch, 4.6 mg per 24 hours, and moves up in steps to 9.5 mg and then 13.3 mg. The FDA prescribing information is explicit about why: doses higher than recommended cause significant nausea, vomiting, diarrhea, decreased appetite, and weight loss. Ask the prescriber for the planned titration timeline and what weight or appetite changes should trigger a call.
Weight loss deserves special attention in dementia care, because many patients are already eating poorly. Agree in advance on how often the patient will be weighed and who is responsible for tracking it. Also ask what to do after a missed patch or an interruption of several days. Restarting at a high dose after a gap raises the risk of the same gastrointestinal effects, so the plan for lapses should be written down before they happen.
Who removes yesterday's patch, and how will you make sure it happens?
This is the single most consequential logistical question. FDA-documented medication errors with this product — most often failing to remove the old patch before applying a new one, so the patient wears two or more at once — have caused hospitalizations and, rarely, death from overdose, according to the FDA label.
A person with Alzheimer's cannot be relied on to remember the old patch, and a patch on the back is easy for a caregiver to miss. Build a routine around it:.
- Assign one person per day to remove the old patch before applying the new one.
- Check the whole application area — a used patch can go unnoticed under clothing.
- Fold used patches sticky-sides together and discard them where the patient cannot retrieve them.
- Keep a simple log of the date and body site of each application.
How do we manage the skin, and when is a reaction serious?
Application-site reactions such as redness and dermatitis occurred in roughly 8–13% of clinical-trial patients, per the prescribing information, so ask about site rotation before the first patch goes on. Rotating among the upper back, chest, and upper arm gives each area time to recover.
Ask what distinguishes ordinary irritation from allergic contact dermatitis. The prescribing information says to suspect allergy when a reaction spreads beyond the patch edges, intensifies with redness, swelling, papules, or blisters, or fails to improve within 48 hours of removing the patch. The patch is contraindicated outright in anyone with hypersensitivity to rivastigmine or other carbamate compounds, so mention any prior reaction to similar drugs.
What medical history must the prescriber know first?
Cholinesterase inhibitors affect more than the brain. Mayo Clinic's drug information notes that rivastigmine can cause slow heartbeat, fainting, and breathing problems, and may raise seizure risk — so disclose any history of bradycardia or irregular heart rhythm, asthma or COPD, seizures, or urinary obstruction, per Mayo Clinic. Stomach history matters too.
Because these drugs increase gastric acid secretion, patients with prior ulcers or gastrointestinal bleeding, or those taking NSAIDs like ibuprofen regularly, should be monitored for bleeding — although rivastigmine trials did not show a significant increase in ulcers or bleeding versus placebo. Ask about surgery as well. The Anesthesia Patient Safety Foundation warns that rivastigmine can prolong or complicate the effect of succinylcholine-type muscle relaxants used during anesthesia. Any anesthesia team must be told the patient wears the patch, and it helps to note it on a medical alert card.
Why choose the patch over rivastigmine capsules?
If the prescriber offers a choice of forms, ask about tolerability. In the 24-week IDEAL trial of 1,195 patients published in Neurology, the 9.5 mg/24-hour patch matched the efficacy of 6 mg twice-daily capsules with about one-third the nausea (7.2% versus 23.1%) and vomiting (6.2% versus 17%), and 70% of caregivers preferred the patch, according to Winblad and colleagues.
The patch also removes the twice-daily pill routine, which matters for patients who resist or forget oral medication. The trade-offs are the skin reactions and the removal discipline described above — for a patient who picks at their skin or a household without a reliable daily caregiver, capsules may still be the safer form.
Frequently Asked Questions
Can the Exelon Patch be used in severe Alzheimer's, or only early on?
It is approved for mild, moderate, and severe Alzheimer's dementia, per the NIH's DailyMed listing — but at every stage it treats symptoms without slowing the disease itself.
What happens if two patches are worn at once by mistake?
Remove both immediately and call the prescriber. Overlapping patches deliver a double dose; FDA-documented errors of this kind have led to hospitalization and, rarely, death.
Where on the body should the patch go?
Clean, dry, hairless skin — commonly the upper back, where a confused patient is less able to peel it off — rotating sites so no area is reused before the skin recovers.
