Postintroduction Reports: Voluntary reports of adverse events temporally associated with bupropion that have been received since market introduction and which may have no causal relationship with the drug include the following:
Body (General) — arthralgia, myalgia, and fever with rash and other symptoms suggestive of delayed hypersensitivity. These symptoms may resemble serum sickness (see PRECAUTIONS).
Cardiovascular — hypertension (in some cases severe, see PRECAUTIONS), orthostatic hypotension, third degree heart block
Endocrine — syndrome of inappropriate antidiuretic hormone secretion, hyperglycemia, hypoglycemia
Gastrointestinal — esophagitis, hepatitis, liver damage
Hemic and Lymphatic — ecchymosis, leukocytosis, leukopenia, thrombocytopenia. Altered PT and/or INR, infrequently associated with hemorrhagic or thrombotic complications, were observed when bupropion was coadministered with warfarin.
Musculoskeletal — arthralgia, myalgia, muscle rigidity/fever/rhabdomyolysis, muscle weakness
Nervous — aggression, coma, delirium, dream abnormalities, paranoid ideation, paresthesia, restlessness, unmasking of tardive dyskinesia
Skin and Appendages — Stevens-Johnson syndrome, angioedema, exfoliative dermatitis, urticaria
Special Senses — tinnitus, increased intraocular pressure
Drug Abuse And Dependence
Humans — Controlled clinical studies conducted in normal volunteers, in subjects with a history of multiple drug abuse, and in depressed patients showed some increase in motor activity and agitation/excitement.
In a population of individuals experienced with drugs of abuse, a single dose of 400 mg of WELLBUTRIN produced mild amphetamine-like activity as compared to placebo on the Morphine-Benzedrine Subscale of the Addiction Research Center Inventories (ARCI) and a score intermediate between placebo and amphetamine on the Liking Scale of the ARCI. These scales measure general feelings of euphoria and drug desirability.
