Razadyne

Generic name: GalantamineBrand names: Razadyne

Why is Razadyne prescribed?

Razadyne can delay or even reverse mental decline in some patients with mild to moderate Alzheimer's disease. It is thought to work by boosting levels of the chemical messenger acetylcholine in the brain. (In Alzheimer's disease, the cells that produce acetylcholine slowly deteriorate.) Razadyne is a temporary remedy. It doesn't work for everyone, and it doesn't halt the underlying disease.

Most important fact about Razadyne

Razadyne therapy starts at a low dose and increases over several months. It is important to wait 4 weeks between dosage adjustments. If treatment with Razadyne is interrupted for several days or longer, the patient will need to start over again at the lowest dose, increasing the dose at 4-week intervals until the former dose is achieved.

How should you take Razadyne?

Razadyne should be taken twice a day, preferably with the morning and evening meals. The drug is available in tablet form and as an oral solution. If you are using the solution, draw the required amount into the measuring pipette that comes with the bottle, then empty the pipette into 3 to 4 ounces of a non-alcoholic beverage. Stir well and administer immediately.

The extended-release capsules, Razadyne ER, should be taken once a day, preferably in the morning with food and water.

  • If you miss a dose...Give it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give two doses at once.
  • Storage instructions...Both the tablets and the oral solution may be stored at room temperature. Do not freeze the solution.
