How Does Donepezil Work?
Donepezil is a cholinesterase inhibitor. It works by increasing the levels of acetylcholine, a neurotransmitter in the brain that is important for memory and thinking. In Alzheimer's disease, acetylcholine levels are often low [2].
What Are the Different Strengths of Donepezil Available?
Donepezil is typically available in several strengths, commonly including 5 mg, 10 mg, and sometimes a higher strength of 23 mg, depending on the formulation and manufacturer [3].
What Are the Side Effects of Donepezil?
Common side effects of donepezil can include nausea, vomiting, diarrhea, loss of appetite, muscle cramps, fatigue, and insomnia [4]. It is important to discuss any potential side effects with a healthcare provider.
Can People With Medicare or Medicaid Get Donepezil at a Lower Cost?
Yes, individuals with Medicare or Medicaid may have their prescription drug costs for donepezil covered or reduced. The specific coverage and cost will depend on the individual's plan benefits and the pharmacy's pricing. Prescription discount cards can also be used by those with these government insurance programs, but they cannot be combined with Medicare Part D or Medicaid benefits.
