Hello, Welcome to Healthcare Magic forum. I understand your concern and appreciate your efforts as a vigilant parent . It seems that your child has a wheeze associated respiratory infection or probably an allergic hyperresponsiveness of airways (similar to asthma). Most common causes in infants for such symptoms are a viral bronchiolitis which is often self resolving or improves with supportive treatment. Since your child was given iv antibiotics , I assume his doctor had diagnosed a bacterial pneumonitis significant enough for prescribing intravenous medications. Ventorlin is a bronchodilator and may provide symptomatic relief in any of the above mentioned conditions however for a definite cure , a thorugh investigational workup and confirmation of diagnosis is mandatory. This can be done by consulting your pediatrician or chest physician who will examine (auscultate) the child, order tests like xrays, blood tests_complete blood counts, esr. , mantoux test,and if needed high resolution ct scan of chest to confirm the diagnosis. Meanwhile for symptomatic relief, bronchodilator and steroid nebulisation can be given to the child if the doctor indicates as per auscultation. Apart from this cough expectorants, antihistamines , multivitamins and zinc supplements can also be given . You should ensure good hydration by giving plenty of fluids and a nutritious diet to your child. This helps in early recovery. Hope I have answered your query. Regards
