cough and nasal congestion
"I find that giving my 4 yr old son Bromfed DM, makes him aggressive and sleepless. I am not sure if its a combination with Albuterol or just by itself. I would say that he is hypersensitive to these drugs including zyrtec, claritin and singulair. When he was younger I would give him bromfed dm and zyrtec also.  He would be hyper and I thought that was his "normal behavior". When he got switched to claritin and singulair its when we noticed how much more aggressive he was becoming.  When I stopped all the medicine,  its when his demeanor completely changed. He suffers from environmental allergies & now when I give him any of the medications above,  his demeanor starts changing.  His aggression is uncontrollable. His doctors don't believe me."
