Monitor for behavioral abnormalities, psychiatric symptoms, emergence or worsening of depression, suicidal ideation, somnolence, fatigue. Hematologic abnormalities: do CBCs in those experiencing significant weakness, pyrexia, recurrent infections, or coagulation disorders. Discontinue if anaphylaxis or angioedema develops. Discontinue at the 1st sign of rash; do not resume if Stevens-Johnson syndrome or toxic epidermal necrolysis is suspected. Renal impairment. Avoid abrupt cessation. Elderly (consider monitoring renal function). Pregnancy: monitor carefully (esp. during 3rd trimester). Nursing mothers.
Somnolence, asthenia, infection, dizziness; behavioral abnormalities (eg, irritability, aggression, anger, depression, anxiety, apathy), psychotic symptoms, coordination difficulties (eg, ataxia, abnormal gait), hematologic abnormalities, dermatological reactions (may be serious). Children: also fatigue, nasal congestion, decreased appetite; BP increases in children 1 month–4yrs (monitor).
