Treats Parkinson's disease.

Azilect (rasagiline) is one of the recommended medicines to treat Parkinson's disease. It is now available in generic, which makes it more affordable for people without insurance.

Treats advanced stages of Parkinson's disease.

Duopa (carbidopa / levodopa) pumps carbidopa/levodopa into your body throughout the day. It is reserved for advanced Parkinson's disease when your symptoms become more frequent than the dosing of your tablets.

Upsides
  • Azilect (rasagiline) is one of the go-to medicines for Parkinson's disease. It can be used in early and late stages of the disease.
  • Taking Azilect (rasagiline) by itself can help slow down Parkinson's disease, but it works better when it's given with other medicines.
  • Azilect (rasagiline) is available as generic as well as brand name, so there are usually lower out-of-pocket costs for you with insurance.
  • Duopa (carbidopa / levodopa) allows you to have better control of your symptoms than oral tablets, especially in later stages of Parkinson's disease.
Downsides
  • It can cause unusual cravings and changes in behavior in some people.
  • Given via pump so you'll need to have a procedure to attach the pump to your body.
  • You'll need to take good care of the pump so that it doesn't get disconnected or infected.
  • Duopa (carbidopa / levodopa) only lasts for 16 hours. You may need to take an extra dose of carbidopa/levodopa as tablet for nighttime control.
