My four year old has had really bad allergies, we just visited an allergist 2 weeks ago, she had a allergy test done, the doctor said she had a reaction to dust and cockroach. she prescribed her zyrtec, singular, and flonaise nose spray. I ve been giving her these meds once a day. Anyways, the day before yesterday she woke up with her eyes swollen and the bridge of her nose. she says it doesnt hurt or bother her but its really noticeable. This has happened before but only for a short while, its been two days the meds arent helping it what should i do?
