Razadyne ER (generically known as galantamine hydrobromide) is a cholinesterase inhibitor that is used to treat mild to moderate dementia (memory loss and mental changes) which is a sign of Alzheimer's disease. It does not cure Alzheimer's disease, but it may improve memory, awareness, and the ability to perform daily functions.

Razadyne ER works by restoring the balance of certain natural substances (neurotransmitters) in the brain. It comes in extended-release capsules that are taken orally.

Use and Dosage

Razadyne ER capsules are an extended-release medication that should be taken orally with food as directed by your doctor. It may be taken once per day in the morning with breakfast on an empty stomach if needed, but drink plenty of fluids with galantamine. The capsules should be swallowed whole without being crushed or chewed, as doing so may destroy the long-acting nature of the drug and increase the risk of side effects.

The recommended starting dosage of Razadyne ER (galantamine) is 8 mg/day taken orally with food. After a minimum of 4 weeks, the dosage may be increased to the initial maintenance dose of 16 mg/day. The dosage should be gradually increased to the target amount to lower the risk of side effects, and the amount prescribed will be based on your response to therapy and medical condition.

If you stop taking the medication for several days, consult your doctor or pharmacist before restarting to reduce your dosage and then increase it gradually according to your doctor's instructions. Use Razadyne ER regularly to gain the most benefit from the medication. Do not discontinue or alter the dosage without consulting your doctor.
