(e.g., oxycodone, hydrocodone, morphine)
- Used for: Moderate to severe pain
- Risk: Drowsiness, confusion, impaired attention—especially in older adults
- Caution: Avoid long-term use when possible; consider non-opioid alternatives
5. Certain Antihistamines (First-Generation)
(e.g., diphenhydramine/Benadryl, doxylamine—found in sleep aids like Unisom)
- Used for: Allergies, colds, sleep
- Risk: Strong anticholinergic effects → drowsiness, disorientation, memory issues
- Safer swap: Use second-gen antihistamines like loratadine (Claritin) or cetirizine (Zyrtec)—non-drowsy and minimal brain impact
6. Proton Pump Inhibitors (PPIs)
(e.g., omeprazole/Prilosec, esomeprazole/Nexium)
- Used for: Acid reflux, GERD
- Risk: Long-term use (>1 year) linked to vitamin B12 deficiency (which causes memory problems) and possible increased dementia risk
- Tip: Use lowest effective dose; don’t take daily unless necessary
7. Some Antidepressants
(e.g., amitriptyline, paroxetine/Paxil)
- Used for: Depression, anxiety, nerve pain
- Risk: Sedation, mental slowing (especially tricyclics and paroxetine due to anticholinergic properties)
- Better options: SSRIs like sertraline (Zoloft) or escitalopram (Lexapro) generally have fewer cognitive side effects
8. Muscle Relaxants
(e.g., cyclobenzaprine/Flexeril, carisoprodol/Soma)
- Used for: Back pain, muscle spasms
- Risk: Drowsiness, dizziness, confusion—especially dangerous when combined with other sedatives
- Caution: Short-term use only; avoid in older adults
💡 How to Protect Your Brain Health
- Review medications annually with your doctor or pharmacist—ask: “Could any of these affect my memory?”
- Avoid “anticholinergic burden”: The more such drugs you take, the higher the risk.
- Prioritize non-drug approaches: Sleep hygiene over sleep aids, physical therapy over muscle relaxants, etc.
- Monitor for changes: Sudden confusion, forgetfulness, or disorientation after starting a new drug warrants a call to your provider.

Many of these drugs are life-improving or even life-saving. The goal isn’t fear—it’s informed partnership with your healthcare team.
