It is important to discuss an action plan with your healthcare professional to determine when it is optimal to double your child's dose of Alvesco for a few days. Salbutamol can be used for coughing spells up to 4 times a day. Additionally, cleaning the nose up to 4 times a day is important for children of this age. For children over 6 years old whose asthma is very well controlled, I sometimes give syrup at bedtime if the cough prevents them from sleeping. There are also natural or homeopathic products that are safe to take at bedtime only, but there are no conclusive studies showing their effectiveness. In short, ideally we rinse the nose and optimize the pumps for the time being. Don't blame yourself for the dose of Benadryl, the doses on the box are generally very low and the risk is quite low unless your child had an asthma attack recently.
