Exelon for Dementia: Benefits, Side Effects, and What You Need to Know

Picture this: your mum is sitting at the kitchen table, staring out the window. You hand her a cup of tea and ask about her day, but something is missing in her eyes. She can’t remember what you did together yesterday, or what she planned for tonight. If you’ve walked this path with someone you love, then you already know the confusion and heartbreak dementia brings. But when I heard about Exelon, a medication that claims to slow down this cognitive fade, my curiosity shot up. Does it really help? What should families expect? I rolled up my sleeves and got into the nitty-gritty, because I know every day, thousands of families ask these same questions—here in Melbourne and around the world.

What Is Exelon and How Does It Work?

Exelon is the brand name for rivastigmine, a drug that’s used to treat symptoms of mild to moderate dementia—usually linked with Alzheimer’s disease or Parkinson’s disease. Now, most people have heard of Alzheimer’s, but only a handful realize that dementia is more like an umbrella. Underneath it, you’ll find a bunch of different conditions. Rivastigmine is one of the cholinesterase inhibitors, which sounds intimidating but just means it helps boost levels of a chemical messenger in the brain called acetylcholine. Think of acetylcholine as the oil in your car’s engine. If it runs low, everything gets noisy and starts to grind—especially memory and learning. People with Alzheimer’s often have really low acetylcholine, which messes with their ability to remember names, finish activities, or even hold conversations.

This drug comes in the form of capsules, oral solution, and skin patches. Those patches are a game-changer, especially for older folks. No more swallowing pills that get stuck, and no taste issues. The patch steadily releases the medicine all day, flattening the rollercoaster of daily doses. Approved by the FDA in 2000 and by Australia’s TGA soon after, Exelon is considered one of the safer meds for dementia care by neurologists.

The thing to know about how Exelon works is this: it doesn’t cure dementia; it isn't a magic fix. What it does—in the ‘best case’—is slow the decline. On average, studies suggest Exelon can buy someone 6–12 extra months of “clearer” functioning. That can mean being able to dress themselves, chat with family, or enjoy a meal at their favourite café. Is that a massive leap? No. But when every extra lucid moment is precious, that difference can matter a lot, especially to families.

Doctors usually start with a low dose to see how someone tolerates it, then increase slowly over a few weeks. And yes, the lower-and-slower rule matters, because rivastigmine can be harsh on the stomach (more on that soon). There are no blood tests to check if Exelon works—it’s all about whether somebody’s memory and function seem to stabilize or decline more slowly.

Who Benefits From Exelon? What Results Can You Expect?

If you’re thinking this sounds like a win for every dementia patient—hang on. Exelon isn’t a universal fix, and not everyone reacts the same way. The strongest effect is seen in people with mild to moderate Alzheimer’s, according to a 2023 meta-analysis published in the "Journal of Neurology". About 30% of patients show noticeable improvement in memory, attention, or daily functioning compared to those taking a placebo. For another third, the progress of decline just slows. The rest, sadly, see little or no effect. There’s no handy checklist to know who will respond; it’s very much trial-and-see.

People with dementia due to Parkinson’s usually get a bit more benefit, especially when it comes to attention and organizing daily routines. Younger patients (under 75) sometimes respond better, but age alone isn’t a dealbreaker. The main hope is not about turning back the clock, but giving someone a better quality of life for a while longer. For my own family, this would mean more time where mum might recognize Lucas or Rosalind, put the kettle on without forgetting, or sing along to her favourite ‘80s hits.

So what does “improvement” actually look like? Most doctors use checklists or rating scales, often the Mini-Mental State Examination (MMSE) or the ADAS-Cog (Alzheimer Disease Assessment Scale – Cognitive). One clinical trial in Australia found patients on Exelon scored 2-3 points higher over six months compared with those not taking any medicine. Now, that might not seem like much on paper, but in real life, it can mean someone greeting you by name instead of looking past you blankly.

There’s a real-world tip from dementia support workers that families swear by: keep a little diary. Track symptoms daily—confusion, mood, sleep, the number of times someone asks the same question. That way, you get a real sense if the medicine is making a difference, even if the shift is slow. And it helps the doctor know if tweaking the dosage or switching treatments could help more.

• If Exelon is working, you might notice fewer lost keys or repetitive questions.
• People sometimes become more sociable and alert.
• It’s common for family members to say things like, “She seems more herself again.”

But don’t expect miracles. The aim isn’t to restore independence but to keep losses at bay a bit longer. And if the medicine isn’t helping, or if side effects get painful, don’t feel bad about moving on. Finding the right balance is the real art.

Practical Tips for Using Exelon at Home

Medications only help if they get taken the right way, without tripping up the rest of the family’s life. If there’s one thing I’ve learned after chatting with pharmacists and carers here in Melbourne, it’s this: managing dementia drugs is as much about planning as medicine. One parent might forget doses, the other might hide patches in the toaster. The challenges are endless.

So, a few practical pointers for families:

• Make a medication chart or use phone reminders—whatever fits your routine.
• If swallowing is an issue, ask about the Exelon patch. Stick it on the upper back or chest. Rotate the spot every day to avoid skin irritation.
• Give medicine with food when possible. This reduces stomach upsets—nausea and vomiting are pretty common, especially at the start.
• Watch for sudden changes: more confusion, dizziness, falls, or bathroom accidents can all be side effects worth flagging.
• If your loved one’s appetite tanks or they lose weight, mention it to the doctor—they might need a lower dose.
• Store the medicine out of sight. Some folks with dementia rummage and double-dose by accident.
• Set up regular check-ins with your GP or geriatrician. Even if things seem stable, it’s important to catch side effects early.

Here’s a tip care workers swear by: stick to a routine. Put the patch on while brushing teeth or before breakfast. If using capsules, take at the same meal (e.g., always at lunch and dinner). Forgetting a dose happens a lot—don’t double up, and get back on schedule as soon as you can.

Don’t be afraid to ask for help. In Victoria, support groups like Dementia Australia run workshops on medication management, and you can ring the National Dementia Helpline for step-by-step advice. I’ve seen families work together—kids helping grandparents, neighbours checking in on patch changes. Dementia care can feel lonely, but you’re not doing this solo.

Side Effects, Risks, and When to Be Cautious

Every medication has a downside, and Exelon is no exception. The most common side effects are stomach-related—nausea, vomiting, diarrhea, and weight loss. Data from a 2022 systematic review showed that more than one in ten users get stomach upset, especially in the first month. If someone throws up a lot or drops several kilos in a short time, it’s often best to drop the dose or take a break.

Then there are skin reactions, mostly with the patches. Redness, itching, or even blisters can crop up. If the patch area gets angry, try moving it to a different spot. Burning or swelling? Call your GP. Some people develop slow heart rates, irregular rhythms, or dizziness. You’ve got to be extra careful if someone already has heart conditions. In elderly folks—like the grandparents of Lucas and Rosalind—there’s also a fall risk if Exelon causes faintness.

Very rarely, people have more serious issues: severe vomiting leading to dehydration, worsening asthma, or even seizures. If any of these pop up, it’s straight to the emergency room. Exelon also interacts with certain antidepressants, anticholinergics, and anesthesia drugs, so keep your doctor in the loop about all medications, including over-the-counter or herbal stuff.

When should you reconsider Exelon? Anyone with uncontrolled asthma, active ulcers, or severe liver or kidney disease has higher risks. Pregnant women or breastfeeding mothers should not use it—though by the time dementia is an issue, this is rare. If memory loss is racing ahead fast and side effects are piling up, it may be time to switch drugs or focus on comfort and dignity rather than medication.

In the end, the exelon decision comes down to the person’s goals, values, and support from family. It’s never as simple as “yes” or “no”—sometimes the best call is just “let’s see how it goes.” And that’s real life when you’re facing a disease that steals memories, bit by bit. You cling to the things that work, gently let go of the things that don’t, and take it one day at a time, holding onto those rare, clear-headed moments with both hands.
