Can bromfed (brompheniramine) and cetrizine be used together? 4 yr old has bad cold/allergy symptoms been taking 1/2 tsp cetrizine bt can she also get 1/2 tsp bromfed (brompheniramine)

No: Bromfed (brompheniramine) already contains an antihistamine.

Cold: Using both drugs may be too sedative for a 4 year old

Nasal saline/mist: It is important to determine if your son has allergies or an upper respiratory infection, or both. Congestion is a common finding in both illnesses. Allergic nasal congestion tends to be watery, associated with sneezing and itching. Flu like symptoms include sore throat and fever. Use an antihistamine with pediatric formulation and dosing for allergies. Avoidance of dust, mold, pollen, smoke.
