Drug class including gabapentin and pregabalin, used for selected neurological indications; they are not appropriate for every radiating pain.
Understanding the approach
Gabapentinoids include gabapentin and pregabalin. They modify selected neural signalling and are used for defined neurological conditions or neuropathic pain indications. They do not decompress nerves, and their role in nerve pain does not guarantee effectiveness for every radiating symptom.
Indications and assessment
Burning or electric pain may guide assessment but is insufficient to select a medicine. Kidney function, age, other drugs and the specific pain cause influence prescribing. Results in diabetic neuropathy cannot automatically be applied to sciatica.
Benefits, limitations and precautions
A controlled pregabalin trial found no significant benefit for sciatica; NICE advises against this class for that indication. Dizziness, drowsiness and swelling can occur. Respiratory depression is particularly concerning with opioids, other sedatives or respiratory disease. Discontinuation may require gradual reduction rather than abrupt stopping.
Place in the care pathway
TAGMED can incorporate medication information into physical assessment, but treatment changes belong to the prescriber. If function does not improve or adverse effects are troublesome, a coordinated review is preferable to automatically continuing or stopping the medicine.
Goals should be practical: walking farther, returning to a chosen activity or reducing symptoms that interfere with sleep. Improvement immediately after a session does not establish lasting benefit. Follow-up compares function with the starting point, records adverse effects and considers progress between appointments. An inadequate response should prompt a review of the clinical explanation or proposed approach, rather than an automatic extension of the same treatment.
Before starting, describe the outcome you want, treatments already tried and difficulties encountered. Ask how the response will be measured and when another option would be preferable. Available reports complement the discussion without replacing your current experience, priorities or preferences.
Frequently asked questions
Are they opioids?
No, but they can still cause adverse effects and dependence.
Is every sciatica an indication?
No. Evidence does not support routine use for sciatica.
Can I drive when starting?
Alertness may be impaired; seek advice before driving.
Why check kidney function?
Elimination of these medicines depends on renal function.
Can I stop overnight?
Do not stop without advice, because an appropriate taper may be needed.
