Hypersensitivity.

Patient with diabetes, compromised respiratory function, respiratory or neurological disease, CHF, history of substance abuse, history of angioedema episodes. Patient taking CNS depressants. Avoid abrupt withdrawal (taper gradually over a minimum of 1 week). Renal impairment. Elderly. Pregnancy and lactation; avoid in pregnancy unless clearly necessary. Patient Counselling This drug may cause dizziness, drowsiness, and vision disorders, if affected, do not drive or operate machinery. Women of childbearing potential must use proven birth control methods during therapy. Monitoring Parameters Assess measures of drug efficacy (pain intensity or seizure frequency). Evaluate patients for history of substance abuse and potential for drug dependency. Obtain renal function tests (periodically); creatine kinase and platelet count (as clinically indicated). Monitor for signs and symptoms of suicidality (e.g. anxiety, suicidal thoughts, depression, behavioural changes), ocular disturbance, weight gain or oedema; respiratory depression and sedation (in patients with underlying respiratory disease).

Significant: Hypersensitivity reactions; dizziness, somnolence, loss of consciousness, confusion, mental impairment; blurred vision, loss of vision, or other changes in visual acuity; renal failure, withdrawal symptoms; convulsions including status epilepticus and grand mal convulsions (during or shortly after discontinuation), CHF (particularly in elderly with compromised CV system), increased risk of suicidal ideation and behaviour; misuse, abuse, and dependence; peripheral oedema, weight gain, increased creatine kinase, decreased platelet count. Ear and labyrinth disorders: Vertigo. Gastrointestinal disorders: Nausea, vomiting, abdominal distension, constipation, diarrhoea, dry mouth, flatulence. General disorders and administration site conditions: Fatigue, oedema, abnormal gait, feeling drunk, fall, feeling abnormal. Metabolism and nutrition disorders: Increased appetite. Musculoskeletal and connective tissue disorders: Arthralgia, back pain, cervical spasm, muscle cramp, pain in limb. Nervous system disorders: Headache, ataxia, abnormal coordination, amnesia, balance disorder, disturbance in attention, dysarthria, hypoaesthesia, lethargy, memory impairment, paraesthesia, sedation, tremor; encephalopathy (particularly in at-risk patients). Psychiatric disorders: Disorientation, euphoric mood, insomnia, irritability. Reproductive system and breast disorders: Decreased libido, erectile dysfunction. Respiratory, thoracic and mediastinal disorders: Nasopharyngitis.
Potentially Fatal: Respiratory depression (particularly in patients with underlying respiratory impairment), angioedema with respiratory compromise.

Concomitant use with drugs that have the potential to produce constipation (e.g. opioid analgesics) may result in reduced lower gastrointestinal tract function (e.g. constipation, paralytic ileus, intestinal obstruction). May potentiate the effects of lorazepam. May increase the risk of angioedema with ACE inhibitors. Increased risk of weight gain and/or fluid retention with thiazolidinedione antidiabetic agents.
