Side Effects of Galantamine (Razadyne)


Side Effects of Galantamine (Razadyne)

Galantamine, available under the brand Razadyne, is treatment for mild to moderate memory disorders, such as Alzheimer’s disease. Razadyne also treats other memory disorders, specifically those of a vascular origin. It does not cure Alzheimer’s disease. Razadyne may help to improve memory, awareness and the ability to perform daily functions. It does this by increasing the amount of acetylcholine in the brain, which may help reduce symptoms in patients with Alzheimer’s disease.

Warnings Before Razadyne Treatment

Do not use Razadyne if you have known allergies to it or if you have severe kidney or liver problems. Tell your physician about every medication you are taking, as some medicines interact with Razadyne. You may not be able to take Razadyne if you will be having surgery, receiving anesthesia, or if you are taking any medications that slow your heart.

Serious Side Effects

The FDA lists the severe side effects of Razadyne. These are:


  • Allergic reactions (hives, rash or itching)
  • Difficulty in breathing or swallowing
  • Tightness in the chest
  • Swelling in the mouth, face, lips or tongue


In addition, be cautious of bloody, black or tarry stools, numbness, burning or tingling, confusion, chest pain, difficult or painful urination, fever, fainting, hallucinations, mood or mental changes, new or worsening symptoms, and other severe side effects. Be sure to discuss side effects with your physician.

Common Side Effects

The common side effects of Razadyne are diarrhea, headache, dizziness, loss of appetite, indigestion, nausea, mild stomach pain or upset, vomiting, trouble sleeping and weight loss. If any of these symptoms persist or worsen, contact your physician (Razadyne label reported by the FDA).

About Pharmacogenetic Testing

Pharmacogenetics came from the human genome project and showed there is variability in many individual’s genetic makeup that is responsible for drug processing or metabolism. Your drug metabolism genes encode the enzymes that process medications. The variations in the genes mean there are variations in the enzymes that do the work of processing medicines.

Know Your Risk with the Rxight® Genetic Test

One way to decrease or prevent side effects is to have your genes tested for variability with the Rxight® pharmacogenetics test from MD Labs. The outcome of the test may reveal that you have a particular sensitivity to Razadyne or any of the 200 drugs and over-the-counter (OTC) products. All that is required is a simple cheek swab from a participating pharmacist. These test results will help your physician treat you with the individualized, precision medical care that you deserve.
