How does Chlorpheniramine interact with over-the-counter cold and flu medications, and what precautions should be taken to avoid adverse reactions or reduced efficacy?
Chlorpheniramine, a sedating antihistamine, can increase drowsiness when taken with other sedatives in cold/flu meds. Avoid alcohol and monitor for excess sedation.
Chlorpheniramine may interact with decongestants in cold medications, increasing the risk of side effects like dry mouth and urinary retention. Stay hydrated and use cautiously.
When combined with multi-symptom cold or flu drugs containing antihistamines, chlorpheniramine can heighten anticholinergic effects such as confusion or dry eyes. Monitor closely.
