Memantine is a prescription medicine used to manage symptoms of Alzheimer’s disease. It helps support thinking and daily function in moderate to severe stages. This page explains how it works, dosing basics, safety, and how to access Memantine price without insurance with US shipping from Canada.
What Namenda Is and How It Works
Memantine belongs to a class called NMDA receptor antagonists. It may reduce excess glutamate activity in the brain, which can help protect nerve cells and support cognition. Also known by the brand Namenda® in some markets, this therapy is often used alongside non-drug support. YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.
Alzheimer’s impacts memory, behavior, and daily routines. By modulating glutamate signaling, this medicine can help stabilize symptoms for some people. It is not a cure, but it can be part of a comprehensive plan that includes caregiver support and routine follow-up. Learn more about the condition in our overview of Alzheimers Disease.
Who It’s For
This treatment is indicated for moderate to severe Alzheimer’s disease. It may be used alone or with an acetylcholinesterase inhibitor when a prescriber deems it appropriate. It is generally not used for mild cognitive impairment. People with severe kidney problems, seizure disorders, or uncontrolled bladder pH changes should discuss risks and benefits with a healthcare professional. It is not typically used in children. For background on the condition, see What Is Alzheimers Disease.
Dosage and Usage
Follow the official label and your prescriber’s directions. Many patients start low and gradually increase the daily amount to reduce side effects. A common schedule for immediate-release tablets begins at Memantine 5 mg once daily, then increases in weekly steps until a target dose is reached as directed. Swallow tablets whole with water. You can take it with or without food.
If swallowing is difficult, ask your clinician about alternative forms. Do not crush or chew unless your pharmacist confirms it is safe for your specific product. If you take this medicine with other cognitive treatments, your prescriber will decide the timing. For more background on uses and titration, read Ebixa Memantine Uses.
Strengths and Forms
Availability may vary by manufacturer. Immediate-release tablets commonly include Memantine 10 mg and lower-dose options. Extended-release capsules exist in some regions and are typically taken once daily in strengths such as 7 mg, 14 mg, 21 mg, and 28 mg. Your prescriber will select the form and strength that fit your plan.
Brands and generics can differ in appearance, imprint, and packaging. The active ingredient remains memantine hydrochloride. If your tablets look different at refill, ask your pharmacist to confirm the supplier change.
Missed Dose and Timing
If you miss a dose, take it when you remember unless it is close to the next scheduled time. If it is near your next dose, skip the missed dose and resume your usual schedule. Do not double up to make up for a missed dose. If several days are missed, consult your prescriber; a re-titration plan may be needed according to the label.
Storage and Travel Basics
Store tablets at room temperature in a dry place away from moisture and direct light. Keep medication in the original child-resistant container with the label intact. Do not store in a bathroom or a hot car. For travel, pack in your carry-on with a copy of your prescription and your prescriber’s details. A medication list helps with security checks and emergency care. Our pharmacy processes orders with a prescription required and verified.
When crossing time zones, keep dosing intervals consistent rather than focusing on exact clock times. Use a pill organizer and reminders to maintain adherence. Keep all medicine out of reach of children and pets.
Benefits
This therapy can help maintain daily function and reduce behavioral symptoms for some patients living with Alzheimer’s disease. In practice, prescribers may combine it with an acetylcholinesterase inhibitor to address different pathways. Tablets are taken once or twice daily depending on the regimen, which can fit into routine schedules. Having generic options may provide more accessible treatment pathways.
Side Effects and Safety
- Dizziness or headache, especially during dose increases
- Constipation or nausea, which may improve over time
- Sleep changes, including insomnia or sleepiness
- Confusion or agitation in some individuals
- Increased blood pressure, monitored by your clinician
- Fatigue or balance problems with falls risk
Serious effects are uncommon but can include allergic reactions, severe dizziness with fainting, new or worsening seizures, or significant changes in mental status. Seek urgent care for swelling of the face or throat, difficulty breathing, or severe rash. People with kidney impairment, urinary conditions affecting pH, or on interacting medicines should use extra caution and follow the label.
Drug Interactions and Cautions
Avoid combining with other NMDA antagonists such as amantadine, ketamine, or high doses of dextromethorphan without medical guidance. Medicines that alkalinize the urine, including sodium bicarbonate or carbonic anhydrase inhibitors, can raise memantine levels. Use caution with sedating agents and alcohol due to additive dizziness. Always tell your pharmacist about all prescription drugs, OTC products, and supplements you take.
What to Expect Over Time
Effects may be gradual. Many caregivers look for small improvements in attention, behavior, or daily tasks. Stabilization can be meaningful even without obvious gains. Adherence, sleep, and a structured routine can support outcomes. Regular check-ins help your prescriber adjust plans if needed. For context on disease changes, see Stages Of Alzheimers Disease.
Compare With Alternatives
Prescribers often consider cholinesterase inhibitors as alternatives or companions. Donepezil is commonly used across disease stages and is taken once daily. Rivastigmine is available as a skin system; the Exelon® Patch may suit those with swallowing challenges or GI intolerance. Choice depends on prior response, tolerability, goals of care, and caregiver support.
Pricing and Access

Availability and Substitutions
Supply can vary by strength and maker. If your selected option is out of stock, your prescriber may recommend an alternative strength or another approved cognitive therapy. Ask about Memantine generic options if you want to switch manufacturers. Do not change products without checking the label and confirming with your pharmacist.
Patient Suitability and Cost-Saving Tips
This treatment may suit adults with moderate to severe Alzheimer’s who can follow a daily plan and attend periodic reviews. People with significant renal impairment, seizure history, or frequent urine alkalinization require careful oversight. To manage costs, consider 60- to 90-day fills when appropriate, set refill reminders, and compare suppliers. Some patients specifically look for Memantine Canadian pricing to budget long term. Keep one medicine calendar for both patient and caregiver.

How does memantine work in the brain?
Memantine blocks NMDA receptors, which respond to the neurotransmitter glutamate. Excess glutamate activity may contribute to symptoms of Alzheimer’s disease. By moderating this signaling, it can help support nerve cell function. It does not repair existing damage or cure the disease. Clinicians may pair it with a cholinesterase inhibitor to target different pathways. The exact benefit varies, so regular follow-up with a healthcare professional is important.
When should memantine be started for Alzheimer’s?
It is typically considered for moderate to severe Alzheimer’s disease. Prescribers assess memory, behavior, daily function, and caregiver input when deciding. Some patients use it alongside a cholinesterase inhibitor for added support. It is not generally used for mild cognitive impairment. Your clinician will tailor the plan and review progress at follow-ups. Always follow the approved label in your region.
What are common side effects of memantine?
The most reported effects include dizziness, headache, constipation, and sleep changes. Some people notice confusion, agitation, or increased blood pressure. These effects may be more likely during dose increases. Serious reactions are uncommon but need urgent care if they occur, such as facial swelling, trouble breathing, or severe rash. Report any new or worsening symptoms to your prescriber or pharmacist.
Can memantine be taken with donepezil or rivastigmine?
Many patients use memantine with a cholinesterase inhibitor like donepezil or rivastigmine. This combination targets different neurotransmitter systems. Your prescriber will decide if the combination is appropriate based on benefits and tolerability. Always share a complete medication list to check for interactions. Do not start, stop, or combine treatments without professional guidance.
What should I do if I miss a memantine dose?
Take the missed dose when you remember unless it is close to your next scheduled time. If it is nearly time for the next dose, skip the missed one and resume the regular schedule. Do not double up doses. If you miss several days, contact your prescriber, as you may need to restart titration per the official label. Medication reminders can help maintain consistency.
How long is memantine therapy continued?
Duration depends on response, tolerability, and goals of care. Clinicians reassess periodically to determine whether to continue. Some patients stay on treatment for extended periods if benefit is observed and side effects are manageable. If benefit appears limited or adverse effects occur, a change may be discussed. Follow your prescriber’s plan and the product’s approved labeling.
Are there important memantine drug interactions?
Yes. Other NMDA antagonists such as amantadine, ketamine, or high-dose dextromethorphan may interact. Medicines that alkalinize urine, including sodium bicarbonate or carbonic anhydrase inhibitors, can increase exposure. Alcohol and sedating drugs may add to dizziness. Provide your pharmacist with a full list of prescription drugs, OTC products, and supplements to check for risks.
