Galantamine (Razadyne) is the third cholinesterase inhibitor and the most overlooked in family education. Its side effect profile overlaps with donepezil but has unique features families should know.
Understanding galantamine side effects helps families ask better questions and make calmer decisions. The detail below covers what doctors usually skip when explaining galantamine side effects.
Nausea and Vomiting
Generally worse than donepezil, particularly at dose increases.
Slow Heart Rate
Like donepezil, can drop heart rate. Combination with beta blockers is risky.
Weight Loss
Reduced appetite and chronic nausea drive measurable weight loss in many patients.
Sleep Disturbance
Vivid dreams and insomnia. Bedtime dosing often makes this worse.
Falls
Dizziness and bradycardia raise fall risk meaningfully.
Rare Severe Reactions
Stevens-Johnson syndrome has been reported. Any rash should prompt immediate call.
Frequently Asked Questions
