My 2 yr old son has cough and wheezing at night while sleeping, no fever. i have cough syrup, ventolin syrup, terbutaline syrup n ventolin nebules.

Wheezing: Check his rom which might be a cause for his wheezing such as a down pillow, stuffed animals, cat or shedding dog. Also look for dust catchers such as venetian blinds or books. Make sure the window is closed and the air conditioning going, hopefully with a clean filter

Asthma control: Use nebulizer with Albuterol as directed by his doctor, ~ 3-4 x/day. Use only one oral bronchodilator, Albuterol, as directed, ~ 3 x/day. Don't give a cough suppressant See doctor now & in follow-up for maintenance medications. Seek evaluations for gastroesophageal reflux & allergies.
