Alzheimer's Medication: What Works and What to Watch For

Are you handling memory loss for yourself or someone you care about? Choosing and managing Alzheimer’s medication can feel confusing. This page breaks down the main drug options, what they do, common side effects, and practical tips you can use right away.

The most common medicines fall into two groups. Cholinesterase inhibitors — donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne) — help boost memory signals in the brain. They’re usually prescribed for mild to moderate Alzheimer's. Memantine (Namenda) works differently and is used for moderate to severe stages; it helps regulate glutamate, a brain chemical tied to learning.

Newer options and what to expect

Recently, anti-amyloid antibodies like aducanumab (Aduhelm) and lecanemab (Leqembi) got attention. These drugs target amyloid protein in the brain and aim to slow disease progression for certain patients. They require careful testing and specialist oversight because benefits are modest for many and risks include brain swelling or bleeding. Ask a neurologist if these treatments are right and whether your clinic can monitor you with MRI scans.

Side effects vary. Cholinesterase inhibitors commonly cause nausea, diarrhea, vivid dreams, or sleep trouble. Rivastigmine can irritate the stomach more but comes as a patch to reduce that. Memantine mostly causes dizziness or headache for some people. Anti-amyloid drugs carry risks of brain swelling (ARIA), so monitoring is essential. Always report new confusion, severe headache, or changes in walking to a doctor immediately.

Practical tips for managing treatment

Start low and go slow. Doctors usually begin with a low dose and increase only if tolerated. Keep a daily pill chart or use a pill box with alarms — memory problems make consistent dosing hard. If swallowing is difficult, ask about patches, liquid formulations, or crushable alternatives. Check interactions: many heart, psychiatric, and gastro drugs interact with Alzheimer’s medicines. Bring all meds, including supplements, to every appointment.

Think beyond pills. Medication works best with routine, sleep hygiene, physical activity, and social connection. Ask your clinician about occupational therapy or cognitive stimulation programs. For caregivers, document behavior changes and side effects in a short daily note — that makes follow-up visits far more productive.

Cost and access matter. Generic donepezil, rivastigmine, and memantine are often affordable. New antibody therapies can be expensive and may require specialist centers. Ask about financial support programs, clinical trials, or hospital social work help if cost is an issue.

Final quick checklist: confirm the diagnosis with a specialist, review possible drug interactions, start at a low dose, set up simple reminders, and schedule follow-up visits for monitoring.
