Hypersensitivity to the substance
Special Precautions-
Galactose Intolerance-Patients with rare heriditary problems of galactose intolerance,

Angioedema- Pregabilin should be discontinued immediately if symptoms of angioedema, such as facial, perioral or upper airway swelling occur
Elderly- Pregabalin treatment has been associated with dizziness and somnolence which could increase the occurance of accidental injury (fall) in elderly patients. There are also reports of loss of consciousness, confusion and mental impairment. These patients should be adviced to excercise caution until they are familiar with the potential effects of this medication
Visual changes- Transcient visual blurring and changes in visual acuity have been reported in patients treated with pregablin. Discontinuation of pregabalin may result in resilution or
improvement of these visual symptoms.
Concomittant antiepileptic therapy-There are insufficient data for the withdrawal of concomittant antiepileptic products, once seizure control with pregabalin in the add-on situation has been reached, in order to reach mono-therapy on pregabalin
Discontinuation- Withdraw pregabalin gradually to minimize the potential of increased seizure frequency in patients with seizure disorders.After discontinuation of short-term and long term treatment with pregabalin withdrawal symptoms have observed in some patients. The following
events have been mentioned- insomnia, headache,nausea, anxiety, hyperhidrosis and diarrhea.
Taper pregabilin over a minimum of 1 week rather than discontinue abruptly
Renal Failure-Although the effects of discontinuation on ther revesibilty of renal failure have not been systematically studied improved renal function following discontinuation or dose reduction of pregabalin has been reported
Ability to perform potentially hazardous tasks- Pregabalin may cause dizziness and somnolence and therfore influence the ability to drive or use machines . Patients should be adviced not to drive , operate machinery or engage in otherpotentially hazardous activities
Pregnancy- Pregabalin should not used during pregnancy unless the benefits outweigh the potential risk to the fetus. Efective contraception must be used in women or child bearing potential

Pharmacology/ Pharmacokinetics:
Pharmacology-
Pregablin binds with high affinity to alpha2-delta site (an auxiliary subunit of volage-gated calcium channels in CNS tissue. In vitro, pregabalin reduces the calcium channel-dependent release of several neurotransmitters ,possibly by modulation of calcium channel function
Pharmacokinetics-
Pregabalin is well absorbed aftr oral administration. Following oral administration of pregabalin under fasting conditions , peal plama concentration is reached within 1.5 hr . Pregabalin oral bioavailability is 90% or more and is independent of dose.
Interaction with food-Rate of pregabalin absorption is decreased when given with food resulting in a Cmax of approximately 25% to 30% and an increase in time of maximal concentration Tmax to
approximately 3 hours.
Interaction with Food:
Rate of pregabalin absorption is decreased when given with food resulting in a Cmax of
approximately 25% to 30% and an increase in time of maximal concentration Tmax to
approximately 3 hours.
Pregnancy and lactation:
