NEURELIV 50 MG is a tablet containing 50 milligrams of pregabalin. 1 Pregabalin is an anticonvulsant and analgesic medication primarily used to treat neuropathic pain (nerve pain) associated with conditions like diabetic neuropathy and postherpetic neuralgia. 2 It is also used as an adjunctive therapy for partial seizures in adults and for the management of fibromyalgia. 3 Pregabalin works by binding to a subunit of voltage-gated calcium channels in the central nervous system, which helps to reduce the release of 4 certain neurotransmitters involved in 5 pain and seizure activity. Common side effects can include dizziness, drowsiness, dry mouth, weight gain, and blurred vision.
