My 13 year old daughter is currently on seretide inhaler, antihistamines and montelukast tabs. She is hardly in school at all as she constantly feels sick and has a sore head which paracetamol doesn't relieve. We have a doctors appointment in couple of days but was just wondering if anyone else, or anyone's children have experienced these symptoms? It's not necessarily these meds that are causing it but I feel it might be likely....but which med is it?!
