Pregabalin side effects and benefits Lyrica
July 25 2017 by Ray Sahelian, M.D.
Pregabalin affects chemicals and nerves in the body that are involved in the cause of seizures and some types of pain. Pregabalin is a medicine designed specifically to relieve common types of nerve pain such as diabetic nerve pain and pain after shingles. Developed by Pfizer, pregabalin, marketed under the brand name Lyrica, is a 3-substituted analogue of gamma-amino butyric acid (GABA) and a compound related to Pfizer's hugely successful antiepileptic drug gabapentin (Neurontin).

Pregabalin for Diabetic Neuropathy
Pregabalin is prescribed for diabetic neuropathy (pain from damaged nerves that happen with diabetes).
Prgabalin for fibromyalgia
The anticonvulsant pregabalin may help reduce pain in some patients with fibromyalgia. Dr. Leslie Crofford at the University of Kentucky, Lexington studied outcomes in 566 patients who had been randomized to receive either pregabalin or placebo during a 26-week double-blind phase of the FREEDOM (Fibromyalgia Relapse Evaluation and Efficacy for Durability of Meaningful Relief) trial. All subjects had responded to pregabalin during a 6-week open-label phase with at least a 50% reduction in mean pain Visual Analog Scale (VAS) score from baseline and a Patient Global Impression of Change rating of at least "much improved." At the end of the randomized phase during which they received an optimized open-label pregabalin dose of 300 mg/d, 450 mg/d, 600 mg/d, or placebo, 61% of patients on placebo had lost their therapeutic response observed during the open-label phase compared with 32% of patients on pregabalin. Dr. Crofford said. During the double-blind phase of the trial, 62% of pregabalin patients reported an adverse event versus 45% of placebo patients. Overall, 82% of adverse events were mild or moderate. Serious events occurred in seven pregabalin and three placebo patients. Dr. Leslie Crofford believes pregabalin is helpful for fibromyalgia.
My comments: I think natural options should be tried first for fibromyalgia before resorting to prescription medications.
Pregabalin Mechanism of Action, how it works
The exact way that it works is not well known.
Pregabalin for seizures

Pregabalin may be a therapeutic agent for medical management of alcohol detoxification.
CNS Drugs. 2016. Abuse Potential of Pregabalin : A Systematic Review. Several case reports and epidemiological studies have raised concern about the abuse potential of pregabalin, the use of which has increased substantially over the last decade. Pregabalin is, in some cases, used for recreational purposes and it has incurred attention among drug abusers for causing euphoric and dissociative effects when taken in doses exceeding normal therapeutic dosages or used by alternative routes of administration, such as nasal insufflation or venous injection.
