Product Details

Description

Memantine contains memantine hydrochloride, which is used to help manage Alzheimer’s disease by affecting chemicals in the brain involved in learning and memory. It is typically available in 5 mg or 10 mg strengths and is taken one or two times a day, with or without food, as prescribed. It is intended for use in adults, mainly the elderly. Memantine works by regulating glutamate activity to help protect brain cells. Possible side effects include dizziness, confusion, or constipation. Follow your doctor’s instructions, take missed doses as soon as you remember, avoid overdose, and store the medicine at room temperature.

Uses and Benefits

Memantine is prescribed to treat Alzheimer’s disease, which can lead to progressive memory loss, confusion, behavioral changes, and loss of independence if not managed properly. It is commonly used in patients with:

  • Alzheimer’s disease
  • Vascular dementia (off-label)
  • Parkinson’s disease dementia (off-label)
  • Other neurodegenerative or cognitive disorders under clinical investigation

It is typically prescribed when cognitive symptoms have progressed beyond mild impairment and begin to interfere with daily living, or when other treatments (such as cholinesterase inhibitors like donepezil) are not sufficient on their own.

Benefits of Memantine

  • Helps slow the progression of symptoms in moderate to severe Alzheimer’s disease.
  • Improves or stabilizes cognitive function, including memory, attention, and language.
  • May reduce behavioral symptoms such as aggression, agitation, and irritability.
  • Helps maintain daily functioning (e.g., dressing, eating, using the bathroom) for a longer period.
Dosage

Recommended Dosage for different age groups and different conditions.

Initial Dose: 5 mg once a day.

Adjustment: Increase by 5 mg per week in divided doses (e.g., 5 mg two times daily) until the recommended maintenance dose is reached.Maximum Dose: 20 mg per day (10 mg two times a day) for immediate-release tablets.

Usage Guide
  • Memantine can be taken with or without food.
  • Take it at the same time each day to maintain steady levels in your body.
  • If using extended-release capsules (Namenda XR), swallow whole. Do not crush or chew.
  • If using the oral solution, measure with the provided dosing device. Do not use a household spoon.
How It Works

Memantine works by blocking N-methyl-D-aspartate (NMDA) receptors in the brain, which are involved in glutamate activity, a neurotransmitter crucial to learning and memory. In Alzheimer’s disease, excess glutamate can overstimulate these receptors and damage brain cells. Memantine helps protect nerve cells by reducing this overstimulation, slowing the progression of symptoms like memory loss, confusion, and difficulty performing daily tasks.

Common side effects of Memantine:

  • Dizziness
  • Headache
