If your parent's Exelon patch was missed or fell off, make sure no old one is on, then apply a new patch to a new spot now. Change it at the usual time tomorrow. Never wear two. After more than 3 days without one, call the doctor first.
That is the rule in the Exelon Patch prescribing information: "If a patch falls off or if a dose is missed, apply a new patch immediately, and then replace this patch the following day at the usual application time." The same label warns that patch mistakes "have resulted in serious adverse reactions; some cases have required hospitalization, and rarely, led to death." Most of them involved "not removing the old patch when putting on a new one and the use of multiple patches at one time."

What to Do After an Exelon Patch Missed Dose
Exelon is a daily rivastigmine skin patch for Alzheimer's or Parkinson's dementia. Once a patch is off, the label puts the half-life in the blood at "approximately 3 hours after patch removal" (the time the body takes to clear half of it).
- Find the old patch first: upper or lower back, upper arms, chest. Your parent should "only wear 1 patch at a time (remove the previous day's patch before applying a new patch)," per the label.
- Put a new patch on a different spot. The patient leaflet puts it simply: "If you miss a dose or forget to change your EXELON PATCH, apply your next EXELON PATCH as soon as you remember."
- Change it at the usual time tomorrow, even if it has been on only a few hours. MedlinePlus agrees: "you should still remove the patch at your regular patch removal time."
- No doubling up. "Do not apply 2 EXELON PATCHes to make up for the missed dose."

Missed the Exelon Patch for More Than 3 Days?
The label draws the line at 3 days.
| Time without a patch | What the FDA label tells the doctor | What it means for you |
|---|---|---|
| One change missed, or the patch fell off | New patch "immediately," replaced the following day at the usual time | Put one on today, on a new spot |
| 3 days or fewer | "restart treatment with the same or lower strength EXELON PATCH" | Leaflet: new patch as soon as you remember. Tell the doctor about the gap (day 3: see below) |
| More than 3 days | "restart treatment with the 4.6 mg/24 hours EXELON PATCH and titrate" | Call before the next patch goes on |
Titrate means stepping back up from 4.6 mg/24 hours, the lowest strength, with at least 4 weeks per step, if each step is tolerated. The leaflet says it plainly: "If you miss more than 3 doses of applying EXELON PATCH, call your healthcare provider before putting on a new EXELON PATCH. You may need to restart EXELON PATCH at a lower dose."
Day 3 itself is where the sources split. The label says "more than 3 days" and the leaflet "more than 3 doses," while MedlinePlus says to call the doctor before starting again if the patch has not been used "for 3 days or longer." At day 3, a call before the next patch goes on covers both.
Why the restart starts low
The label ties the low restart to stomach side effects. Nausea and vomiting are "dose-related," and when patches stopped for more than 3 days because of side effects, it says to restart at 4.6 mg/24 hours "to reduce the possibility of severe vomiting and its potentially serious sequelae." In its 24-week trial, nausea was 7% on the 9.5 mg patch and 21% on a stronger, unapproved one; vomiting, 6% and 19%. The label also notes that "dehydration may result from prolonged vomiting or diarrhea and can be associated with serious outcomes."
The label describes one case of "severe vomiting with esophageal rupture" (a tear in the food pipe). That person restarted rivastigmine taken by mouth, not the patch, "without retitration after 8 weeks of treatment interruption."
One line in the label is aimed at you: "It is critical to inform caregivers that if therapy has been interrupted for more than 3 days because of intolerance, the next dose should not be administered without contacting the physician regarding proper retitration." Put simply, if the patches stopped for more than 3 days because your parent was sick from them, the next one waits until you have talked to the doctor. The label also asks caregivers "to monitor for gastrointestinal adverse reactions and to inform the physician if they occur," in particular "when treatment is initiated or the dose is increased."
When you call, have these ready:
- The strength printed on the patch (4.6, 9.5 or 13.3 mg/24 hours).
- The date the last patch came off, and why: forgotten, ran out, a hospital stay (discharge tips), or nausea and vomiting.
- Any new medicines, especially what the leaflet calls "an anticholinergic medicine, such as an allergy or cold medicine, a medicine to treat bladder or bowel spasms." Bladder pills like oxybutynin are one example.
Rivastigmine Patch Fell Off? Where to Put the New One
The patient leaflet is specific: "If your EXELON PATCH falls off before its usual replacement time, put on a new EXELON PATCH right away. Replace the new patch the next day at the same time as usual." It also says: "Do not use overlays, bandages, or tape to secure an EXELON PATCH that has become loose or try to reapply an EXELON PATCH that has fallen off."
Use a new area of clean, dry, hairless skin with no redness, irritation, burns or cuts. For a parent who picks at patches, the instructions add a line just for you: "Instructions for Caregivers: Apply EXELON PATCH to the upper or lower back if it is likely that the patient will remove it." Otherwise the upper arm or chest works. Avoid tight clothing and belts, press it down firmly for 30 seconds, and skip the same spot for at least 14 days.
Showers are fine: the label says your parent "may wear the patch during bathing and in hot weather." Check the edges after a bath or swim, and keep the patch away from saunas and long sun.
A patch found on the floor still has medicine in it; per the label, "drug still remains in the patch after 24-hour usage." Fold it in half, sticky sides together, put it in its pouch, and throw it away out of reach of children and pets. Then wash your hands with soap and water.
Exelon Patch Overdose From Wearing Two Patches
This is the most common patch mistake the label reports. In a study of 614 people using the patch with a caregiver, co-written by staff of Novartis (Exelon's maker), 27.7% reported some incorrect use before the study and 18.0% during it, including extra patches and wrong placement.
In a 2012 case report, health care staff mistakenly put six patches on an 87-year-old man at once, on two days in a row. He had nausea, vomiting and kidney failure, and died; the authors judged the rivastigmine "caused or contributed" to his dehydration.
If you find two patches on your parent:
- Call 911 if your parent has collapsed, had a seizure, has trouble breathing, or can't be woken (MedlinePlus).
- If there are no symptoms, MedlinePlus says to "remove the patch or patches. Call your doctor and do not apply any additional patches for the next 24 hours."
- In every case, call right away. From the leaflet: "call your healthcare provider right away. If you are unable to reach your healthcare provider, call your local Poison Control Center at 1-800-222-1222 or go to the nearest hospital emergency room right away." In Canada, call 1-844-764-7669, or 1-800-463-5060 in Quebec (Health Canada).
MedlinePlus lists overdose signs such as nausea, vomiting, diarrhea, extra saliva, sweating, a slow heartbeat, dizziness, muscle weakness, trouble breathing, fainting and seizures. For pills taken twice, see took medication twice by mistake.
Is an Exelon Patch Rash or Itching an Allergy?
Red or itchy skin where the patch sat is common, and on its own it is not a sign of allergy. The label says these skin reactions "are not in themselves an indication of sensitization." In the IDEAL trial, redness and itching came up most often, and during its 24-week phase 89.6% of people on the 9.5 mg patch had "no, slight or mild" signs at their worst skin reaction.
An allergy looks different. The leaflet draws the line here: "Stop using EXELON PATCH and call your healthcare provider right away if you experience reactions that spread beyond the patch size, are intense in nature and do not improve within 48 hours after the patch is removed." Signs can include itching, redness, swelling, warmth or tenderness, and peeling or blistering skin that may ooze or crust over. After a reaction like this, the leaflet says not to use the patch again.
How Pillo Helps When You Change the Patch
The label suggests making the change part of "a daily routine, such as the daily bath or shower."
If your parent lives with you, or you change the patch in person each day, add your parent as a dependent in your own app (Dependents Management is free for up to two dependents; a third needs the paid plan). Pillo's persistent alarm keeps ringing on your phone until you mark the change done. Dose Notes let you log the spot you used, so the 14-day rule is easy to follow. Adherence Reporting shows which days were missed, so you have the count ready when you call.
If your parent lives on their own across town, an alarm on your phone does not put a patch on their back. Our guide to managing a parent's medications from another state covers what helps from a distance.
FAQ
Should I skip the patch if the next change is almost due?
The sources differ. MedlinePlus says, "If it is almost time for the next patch, skip the missed patch and continue your regular dosing schedule." The Exelon label has no skip rule; we searched it and one generic label for "skip" and "almost time" and found neither. Ask your parent's pharmacist which rule to follow.
Can rivastigmine patches be cut in half?
No. The instructions say, "Do not cut or fold the EXELON PATCH itself," and the label says not to use a patch that is "cut, damaged, or changed in any way." A lower dose means a lower-strength patch, down to 4.6 mg/24 hours, prescribed by the doctor.
Can you stop the Exelon patch abruptly?
MedlinePlus says, "Do not stop using transdermal rivastigmine without talking to your doctor." One exception: for the spreading skin reaction above, the leaflet says stop and call right away. After more than 3 days off, the restart rule applies.
Do generic rivastigmine patches follow the same rules?
The generic label we checked, Mylan's rivastigmine transdermal system (revised 9/2024), gives the same steps: a new patch "immediately" after a missed dose or a fall-off, one patch at a time, and the same 3-day restart line.
What if I can't remember whether I changed the patch today?
Check your parent's back, upper arms and chest. If a patch is on, do not add a second one; the label says to "only wear 1 patch at a time." If you can't tell whether it is today's, ask the pharmacist before swapping it. If no patch is on anywhere, treat it as a missed dose and put a new one on. If it may have been off for more than 3 days, call the doctor first. Writing the date and time on each patch with a ballpoint pen, as the leaflet suggests, helps next time.
