Common use
Memantine is prescribed for patients with moderate to severe Alzheimer’s disease. It helps regulate the activity of glutamate, a chemical messenger in the brain, which can reduce abnormal brain signaling and support memory and cognitive function.

Dosage and direction
Memantine is typically taken once or twice daily, depending on the prescribed regimen. Capsules, tablets, or oral solutions should be taken with or without food. Follow your healthcare provider’s dosing instructions carefully, and do not change the dose without consulting your doctor.

Precautions
Before using memantine, inform your doctor if you have kidney problems, heart conditions, seizures, high blood pressure, or a history of urinary tract obstruction. The drug may cause dizziness, headaches, or confusion, so use caution when driving or operating machinery.

Contraindications
Memantine is contraindicated in individuals with known hypersensitivity to memantine or any of its components. Avoid use if a severe allergic reaction to this or similar medications has occurred.

Possible side effect
Common side effects include dizziness, headache, constipation, confusion, and sleep disturbances. Serious side effects may include severe allergic reactions, sudden changes in mood or behavior, hallucinations, or heart rhythm abnormalities. Seek medical attention if serious symptoms occur.

Drug interaction
Memantine may interact with other NMDA antagonists (such as amantadine or ketamine), certain blood pressure medications, and drugs that affect kidney function. Always inform your doctor of all prescription medications, over-the-counter products, and supplements you are taking.

Missed dose
If a dose is missed, take it as soon as you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and continue with the regular dosing schedule. Do not take two doses at once.

Overdose
Symptoms of overdose may include severe dizziness, nausea, vomiting, confusion, hallucinations, or fainting. Seek immediate medical attention if an overdose is suspected.

Storage
Store at room temperature, away from heat, moisture, and light. Keep the medication in its original container and out of reach of children and pets.
