Key takeaways
Qnasl (beclomethasone) and flunisolide are both corticosteroid nasal sprays used to treat nasal symptoms caused by seasonal or year-round allergies. Qnasl is available in two strengths, including a low dose for children as young as 4. Flunisolide, on the other hand, can be used for people 6 years and older. Qnasl is typically used once daily, while flunisolide is used twice or three times a day depending on your age. Qnasl has a built-in dose counter and doesn't need to be primed before first use, whereas flunisolide requires priming before the first use and after cleaning it. Common side effects of Qnasl include nasal discomfort, headache, and nosebleeds, while flunisolide commonly causes nasal burning and stinging. Both medications can slow growth in children if used long-term and may increase the risk of infections. Qnasl is available only as a brand name, while flunisolide is available as a lower-cost generic.
