Is safe to give salbutamol for my 9 month baby?

Yes: This is indicated for respiratory conditions that cause constriction or wheezing in the airways, dose is generally 0.63-2.5 mg through nebulizer.

Salbutamol/albuterol: This is a standard medication used to dilate distal airways when used in aerosolized forms.I often use it is early as a few months of age when indicated by the condition and response.
