Gabapentin
Gabapentin is an anticonvulsant used for selected seizure disorders and some forms of Neuropathic Pain. Benefit varies by condition, and kidney function affects how the body clears it.
Key points
- Gabapentin can cause drowsiness, dizziness, blurred vision and unsteadiness, especially after starting or changing treatment.
- Opioids, alcohol and other sedating medicines can increase sedation and the risk of serious breathing problems.
- Do not stop gabapentin suddenly; a clinician should plan a gradual change to reduce withdrawal symptoms and seizure risk.
Select a listed product and pack to order online. Product information is not a pain or seizure recommendation. Whether it suits you depends on diagnosis and kidney function; ask your doctor or pharmacist.
What gabapentin is used for
Gabapentin may be used as part of Epilepsy treatment and for selected nerve-pain syndromes. It does not treat every type of chronic pain, and response should be reviewed rather than assumed from the diagnosis alone.
How gabapentin works
Gabapentin binds the alpha-2-delta subunit of voltage-gated calcium channels and reduces selected excitatory signalling. Despite its name, it does not act directly like the neurotransmitter GABA.
Important safety checks
Kidney function, breathing disease, fall risk, pregnancy, mood symptoms, substance-use history and other sedating medicines require review. Do not drive or operate machinery until its effects are known. Taking more than prescribed or combining it with opioids can be dangerous.
When to seek urgent care
Seek emergency help for slow or shallow breathing, inability to wake, blue or grey lips, severe confusion, facial or throat swelling or a severe rash. New suicidal thoughts, extreme agitation or a marked increase in seizures needs urgent professional help.
