The medicine and healthcare regulatory agency (U.S.) has apparently received reports of multiple patches being applied to patients and patches not being removed in a timely manner.
The drug used in the Alzheimers patch is rivastigmine (Exelon) and is used to treat mild to moderate stages.
The overdose warning says that in all cases of suspected overdose, all patches should be immediately removed and none reapplied for 24 hours.
Bottom Line
As always follow the label on all medications.
