Special care should be taken when using chlorpheniramine maleate in children and the elderly as they are more likely to experience the neurological anticholinergic effects and paradoxical excitation (e.g. Increased energy, restlessness, nervousness). Avoid use in elderly patients with confusion.
The anticholinergic properties of chlorphenamine may cause drowsiness, dizziness, blurred vision and psychomotor impairment in some patients which may seriously affect ability to drive and use machinery.
The effects of alcohol may be increased and therefore concurrent use should be avoided.
If symptoms do not go away within 5 days talk to your pharmacist or doctor.
Keep all medicines out of the reach and sight of children.
Although most antihistamines should be avoided by patients with porphyria, chlorpheniramine maleate has been used and is thought to be safe.
Should not be used with other antihistamine containing products, including antihistamine containing cough and cold medicines.
Concurrent use with drugs which cause sedation such as anxiolytics and hypnotics may cause an increase in sedative effects, therefore medical advice should be sought before taking chlorphenamine concurrently with these medicines.
