My son who is 3 1/2 was diagnoised with asthma at 9 months old. he's been on signular chewables, and an occassional neubulizer (when needed). we've moved and my insurance will not kick in for another 30-60 days...he ran out of singular about a week ago, and now he's coughing, wheezing, and haveing trouble breathing i wanted to know if there was something over the counter that i can give him to help him untill i can get my insurance and i can get his medication filled?
