Interaction Details
Donepezil is classified as belonging to the following category: Topical Drugs
Topical DMSO might increase the effects and adverse effects of topical drugs.
Evidence from animal studies and limited human studies suggests that DMSO may potentiate the action of numerous topical medications by increasing their absorption through the skin. This increase in absorption seems to depend on the concentration of DMSO and the molecular weight of the medication.

Dimethylsulfoxide (dmso) Overview
Dimethylsulfoxide (DMSO) is a colorless, odorless liquid that has a number of industrial and medical uses.
In a medicinal sense, DMSO is most commonly used as a topical pain reliever and anti-inflammatory agent. It is applied to the skin as a cream or gel, and is sometimes used to treat conditions such as muscle strains, sprains, and arthritis. DMSO is also an FDA-approved treatment for interstitial cystitis, a condition that causes bladder pain and frequent urination, when given via intravesical instillation (administration directly into the bladder).
DMSO is often added to topical preparations to increase the skin penetration of some medications.
Donepezil Overview
-
Donepezil is used to treat dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and may cause changes in mood and personality) in people who have Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Donepezil is in a class of medications called cholinesterase inhibitors. It improves mental function (such as memory, attention, the ability to interact with others, speak, think clearly, and perform regular daily activities) by increasing the amount of a certain naturally occurring substance in the brain. Donepezil may improve the ability to think and remember or slow the loss of these abilities in people who have AD. However, donepezil will not cure AD or prevent the loss of mental abilities at some time in the future.
