Precautions
Abrupt or rapid discontinuation of Pregabalin may produce some symptoms including insomnia, nausea, headache and diarrhoea. So Pregabalin should be tapered gradually over a minimum of 1 week rather than discontinued abruptly. Pregabalin treatment may associate with creatine kinase elevations. It should be discontinued if myopathy is diagnosed or suspected or if markedly elevated creatine kinase levels occur. Discontinue treatment if patients develop severe angioedema. Regular vision check is recommended. May decrease platelet count and prolong PR interval. Patient w/ history of angioedema episodes, severe CV disease, renal impairment. Pregnancy and lactation.
Patient Counselling May impair ability to drive, operate machinery or engage in hazardous activities. Monitoring Parameters Monitor visual disturbances.
Closely observe for clinical worsening, suicidality and unusual changes in behaviour.
Suicidal thoughts or behaviors
Antiepileptic drugs increase risk of suicidal thoughts or behavior in patients taking these drugs for any indication; monitor for emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior
Inform patients, their caregivers, and families of the increase the risk of suicidal thoughts and behavior; advise to be alert for the emergence or worsening of signs and symptoms
Angioedema
Angioedema of the face, extremities, lips, tongue, glottis, and larynx has been reported during initial and chronic treatment, including reports of life-threatening angioedema with respiratory compromise requiring emergency intervention
If laryngeal stridor or angioedema of the face, tongue, or glottis occurs, discontinue therapy and institute appropriate therapy immediately
Coadministration of ACE inhibitors or mTOR (mammalian target of rapamycin) inhibitors (eg, temsirolimus, sirolimus, everolimus), or previous history of angioedema may increase risk
Lactation: Unknown if excreted in milk; not recommended
Pregnancy-Lactation
Pregnancy
There are no adequate and well-controlled studies with pregabalin in pregnant women
Animal data
In the animal fertility study with pregabalin in male rats, adverse reproductive and developmental effects were observed
In animal reproduction studies, increased incidences of fetal structural abnormalities and other manifestations of developmental toxicity, including skeletal malformations, retarded ossification, and decreased fetal body weight were observed in the offspring of rats and rabbits given pregabalin orally during organogenesis, at doses that produced plasma pregabalin exposures (AUC) greater than or equal to 16 times human exposure at the maximum recommended dose (MRD) of 600 mg/day
Lactation
Small amounts of pregabalin have been detected in the milk of lactating women
Based on animal studies, there is a potential risk of tumorigenicity with pregabalin exposure via breast milk to the breastfed infant
Available clinical study data in patients greater than 12 years of age do not provide a clear conclusion about the potential risk of tumorigenicity with pregabalin
Because of the potential risk of tumorigenicity, breastfeeding is not recommended during treatment
Interactions
May potentiate the effects of lorazepam. Additive CNS depressant effects w/ opiates and benzodiazepines. May increase risk of angioedema w/ ACE inhibitors. May increase risk of wt gain and peripheral oedema w/ thiazolidinediones.

Mode of Action
Pregabalin is an analog of the neurotransmitter GABA. It binds potently to the alpha2-delta subunit resulting in modulation of Ca channels and reduction in the release of several neurotransmitters, including glutamate, norepinephrine, serotonin, dopamine, calcitonin gene-related peptide and substance P.
