When Pain Medication Stops Working
Three Things to Check First
Before concluding that medication has failed, bring these questions to your doctor:
1. Is the Current Medication the Right Match?
Different types of pain respond to different medications:
| Type of pain | What it feels like | Medications that help |
|---|---|---|
| Inflammatory pain | Hurts with movement; swelling or warmth | NSAIDs (e.g., ibuprofen, naproxen, celecoxib) |
| Neuropathic pain | Burning, tingling, electric-shock sensations; painful to the touch | Pregabalin (Lyrica), gabapentin, duloxetine (Cymbalta) |
| Reduced blood flow pain | Pain with walking that eases with rest | Limaprost (a prostaglandin analog) |
| Mixed pain | A combination of the above | Combination therapy |
If you've only been taking anti-inflammatory painkillers, your pain may have shifted to neuropathic pain, which requires a different class of medication entirely — such as pregabalin or duloxetine.

2. Are You Taking the Medication Correctly?
| Common issue | How it affects you |
|---|---|
| Only taking it "as needed" when pain spikes | Blood levels never stabilize, so the medication can't work as designed |
| Reducing the dose due to side effect concerns | You may not be taking enough for it to be effective |
| Frequently forgetting doses | The effect is interrupted |
Medications like pregabalin and duloxetine work best when taken at the same time every day, consistently. They are not meant to be taken only when pain strikes.
3. Side Effects Making It Hard to Continue?
Some medications cause side effects that are more pronounced in older adults:
| Medication | Common side effects | What can be done |
|---|---|---|
| Pregabalin (Lyrica), gabapentin | Dizziness, unsteadiness | Start at a low dose; take at bedtime |
| Tramadol | Nausea, constipation | Add anti-nausea medication or a stool softener |
| NSAIDs (long-term) | Stomach problems, kidney issues | Take with a stomach-protecting medication; monitor with blood tests |
If side effects are the reason you can't continue, talk to your doctor about switching to a different medication or exploring non-medication options.
