Memantine Description
Memantine is a prescription medicine used to treat symptoms of moderate to severe Alzheimer's disease. In online pharmacies it is offered in tablet and liquid forms. This review explains how it works, how to take it, and what to expect.
What is Memantine?
Memantine belongs to NMDA receptor antagonists. It helps reduce abnormal brain signals that can occur in Alzheimer’s disease. It is usually prescribed when other medicines do not provide enough relief. The medicine is not a cure, but it can help with daily thinking and function for some people.
How Memantine works
Memantine blocks excitatory signals from glutamate, a brain chemical involved in learning and memory. By moderating this activity, it may slow some symptoms and protect nerve cells from excessive stimulation. This can translate into modest improvements in thinking, memory, and everyday tasks for some patients. The effect varies, and gradual, steady use is important.
How to take Memantine
Dosing is started low and increased gradually. The typical plan begins at 5 mg once daily for week 1, then 5 mg twice daily in week 2, and 10 mg twice daily as maintenance. The usual total daily dose is 20 mg. Tablets are swallowed with water, and the timing can be morning and evening as prescribed. If you have kidney problems, your doctor may adjust the dose or schedule. Always follow the exact plan given by your clinician.
Onset and benefits
Some people notice improvements after several weeks, while others may see smaller changes over 3 to 6 months. Benefits depend on disease stage, overall health, and other treatments you may use. Regular daily use is important, even if you do not see quick changes right away. In some cases memantine is used alongside other Alzheimer’s medicines for a combined effect.
Side effects
Common side effects include dizziness, headache, constipation, and confusion. Some people may feel tired or have higher blood pressure. Less often, people report mood changes or skin reactions. If side effects persist or worsen, contact your doctor or pharmacist. Seek urgent care for signs of an allergic reaction or severe confusion.
Precautions and who should avoid
Tell your doctor if you have kidney problems, dehydration, or a history of seizures. Memantine can interact with other medicines, including over-the-counter products and supplements. Pregnancy and breastfeeding require careful discussion of risks and benefits. People with certain medical conditions should be monitored closely, and dosage may be adjusted accordingly.
Interactions with other medicines
Memantine can interact with other drugs that affect the brain or kidneys. Avoid combining with other NMDA antagonists unless a clinician directs it. Some medicines may alter memantine levels, so always disclose all prescriptions, as well as nonprescription drugs and vitamins, to your pharmacist.
Missed dose and overdose
If you miss a dose, take it as soon as you remember unless it is near the time of your next dose. Do not double the dose to catch up. In case of suspected overdose, seek medical help immediately or contact poison control. Symptoms of overdose may include extreme sleepiness, irregular heartbeat, or confusion.
Storage and availability
Store memantine at room temperature, away from moisture and heat. Keep the bottle tightly closed and out of reach of children. Do not use it after the expiry date printed on the package. If you need to stop treatment, consult your doctor to plan a safe approach and avoid withdrawal symptoms.
