Is there anything i can give my 2 year old who has persistent cough? i've already given him albuterol and budesonide. i read benadryl (diphenhydramine) helps?

See his doctor: Cough can be due to several causes, reactive airway disease is just one, sinusitis, ear infection or any upper respiratory tract infection can still cause it. How did you give him the albuterol and the budesonide? I trust at his age you used a nebulizer, but make sure you've mixed the right dosage and the mask was fitting to his face so the medicine isn't wasted, see his doctor for better assessment
