GABAPENTIN belongs to a class of medications called 'anticonvulsants' used to prevent neuropathic pain (pain due to damaged nerves), fibromyalgia (musculoskeletal pain), and epilepsy (fits).
It works by binding to the specific site on voltage-gated calcium channels and block the action of overexcited channels; this helps in relieving nerve pain and lowers the risk of seizures. Overall it reduces nerve pain by interfering with pain signals traveling through the damaged nerves and the brain.
Like all medicines, GABAPENTIN also has some side effects, though it is not mandatory for everyone to experience them. Common side effects of GABAPENTIN include feeling sleepy, tired or dizzy, feeling sick (nausea), being sick (vomiting), diarrhoea, getting more infections than usual, mood changes, swollen arms and legs, blurred vision, dry mouth, difficulties for men getting an erection, weight gain, feel hungry, memory problems, and headaches. Most of these side effects of GABAPENTIN do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.
