Nervous system side effects have included central nervous system (CNS) depression, resulting in drowsiness and sedation in nearly 50% of patients treated. This effect has often been transient and ceased with continued use. Motor skills have be impaired and patients should be advised to avoid tasks which require attention. Patients should also avoid concomitant use with alcohol and other sedative-hypnotic drugs. Dyskinesias have rarely been reported following chronic use of brompheniramine (the active ingredient contained in Brovex CT) [Ref]
A few cases of dyskinesias and tremors, often of the face, have been reported in patients whose chronic use of brompheniramine extended over a period of up to 10 years. Some of these cases were only partially relieved by discontinuation of the drug. Haloperidol was successful in relieving symptoms in these patients. Spasmodic torticollis has been reported in a child given brompheniramine over an eight month period.[Ref]
Ocular side effects have included blurred vision, diplopia, and dry eyes due to anticholinergic effects.[Ref]
