My dd is 17 and suffers very badly with allergies. She has anaphylactic reactions to nuts and seeds and is highly allergic also to dust mites. She has been taking an antihistamine at night time since she was around 10 and also using a steroid nasal spray. Unfortunately the nasal spray this year has started causing her some horrible spots around her nose which require a month of antibiotics to clear them up every time so she's stopped using it (we tried switching to a different type first) and is really suffering - sneezing constantly, eyes sort, lots of hives, itching all night. The GP has prescribed a stronger antihistamine but she thinks it's not as good as the older one so far. The GP is also looking into prescribing Montelukast / Singulair and I wondered if anyone has any experience of this? Or if there's anything you can think of which could be used as an alternative nasal spray with no steroid?
