General

The most common adverse reactions to this drug are dizziness, somnolence, dry mouth, edema, blurred vision, weight gain, and "thinking abnormal" (primarily difficulty with concentration/attention); the more commonly reported events in pediatric patients include increased weight and increased appetite.^[Ref]

Nervous system

• Very common (10% or more): Dizziness (up to 37%), somnolence (up to 25%)
• Common (1% to 10%): Neuropathy, ataxia, vertigo, incoordination, tremor, abnormal gait, headache, speech disorder, twitching
• Uncommon (0.1% to 1%): Syncope, stupor, myoclonus, psychomotor hyperactivity, dyskinesia, dizziness postural, intention tremor, nystagmus, hyporeflexia, hyperesthesia, burning sensation, ageusia, malaise
• Rare (less than 0.1%): Convulsions, parosmia, hypokinesia, dysgraphia, shock, circumoral paresthesia, dysarthria, hyperalgesia, hyperkinesia, hypokinesia, hypotonia, myoclonus, neuralgia cerebellar syndrome, cogwheel rigidity, coma, dysautonomia, dystonia, encephalopathy, extrapyramidal syndrome, Guillain-Barre syndrome, hypalgesia, intracranial hypertension, torticollis, trismus, peripheral neuritis
• Postmarketing reports: Coma^[Ref]

Among pediatric patients receiving this drug for the treatment of partial onset seizures, somnolence was reported in 21% of drug treated patients and 14% of placebo patients, occurring more frequently at higher doses. Somnolence includes related terms of lethargy, sluggishness, and hypersomnia.

Patients treated for central neuropathic pain due to spinal cord injury have experienced an increased incidence of CNS adverse effects, especially somnolence. This may be due to an additive effect with concomitant medications.

There are postmarketing reports of respiratory failure and coma in patients taking pregabalin and other CNS depressant agents.^[Ref]

Cardiovascular

• Very common (10% or more): Peripheral edema (up to 12%)
• Common (1% to 10%): Chest pain
• Uncommon (0.1% to 1%): Hypotension, hypertension, hot flushes, flushing, peripheral coldness, heart failure, postural hypotension, syncope
• Rare (less than 0.1%): ST depressed, ventricular fibrillation
• Frequency not reported: PR interval prolongation^[Ref]

In controlled clinical trials in adult patients, peripheral edema was reported in 6% of patients receiving this drug compared with 2% in the placebo group; 0.5% and 0.2% of patients withdrew due to peripheral edema in the drug treated group and the placebo group, respectively.

Analyses of clinical trial ECG data has shown the mean PR interval increase was 3 to 6 msec at doses greater than or equal to 300 mg/day. Subgroup analyses did not identify an increased risk of PR prolongation in patients with baseline PR prolongation or those taking other PR prolonging medications, although the number of patients in the study was not sufficient to draw a definitive conclusion.^[Ref]
