Central nervous system side effects have included depression resulting in drowsiness in 75% or more of treated patients. Dyskinesias have rarely been reported following chronic use of chlorpheniramine.
Nearly all patients treated with chlorpheniramine experience drowsiness. This drowsiness may subside in some patients with extended use.
Few cases of dyskinesias and tremors, often of the face, have been reported in patients whose chronic use of chlorpheniramine extended over a period of 3 to 10 years. Some of these cases were only partially relieved by discontinuation of the drug. Haloperidol was successful in relieving symptoms.

Gastrointestinal side effects have included dry mouth and constipation in up to one-third of treated patients.
Cardiovascular
Cardiovascular side effects have included hypotension, tachycardia, and palpitations.
Ocular
Ocular side effects of chlorpheniramine may include blurred vision, diplopia, and dry eyes due to anticholinergic effects.
Genitourinary
