My father is 77 years old and mildly asthmatic. He has been treated with antibiotics and nebulization for 7 days and still complains of mild short breath once in 3 days. Dr. has prescribed to give asthalin nebulization on sos basis. However we are sceptical to give this regularly. Need your guidance if we can give this on a regular need basis or not. If not want is to be done as his xray n other parameters are normal as per reports.
