What It's For & How To Take
Memantine is used to help treat confusion and dementia associated with Alzheimer’s Disease. Alzheimer’s happens when nerve cells in the brain die. Nerves get tangled and messages slow or stop.
Medications for Alzheimer’s disease focus on two main areas. The first type of medication increases the level of chemicals that send messages in the brain. The second type of medication slows the nerve death.
Neither of these two treatments cures Alzheimer’s. They may help improve memory, awareness, and possibly make it easier to do daily chores.
Memantine works to block a chemical in the brain. This may help slow the progression of nerve damage.
Memantine is usually started at a low dose, once daily, with or without food. Over a couple of months, your doctor may increase your dose and how often you take it. Your dose depends on your response to the medication.
If you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
