Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Qvar RediHaler (beclomethasone) and Allegra (fexofenadine) are used for different health conditions and belong to different medication classes. Qvar is an inhaled corticosteroid used to manage asthma by reducing lung inflammation, while Allegra is an antihistamine used to relieve allergy symptoms and hives. Qvar requires a prescription and must be used twice daily, whereas Allegra is available over-the-counter and can be taken as needed. Qvar is not suitable for treating sudden asthma attacks, whereas Allegra starts working within 2 hours so it can be taken when allergy symptoms start. Additionally, Qvar can cause oral thrush if you don't rinse your mouth after use, while Allegra's common side effects include headache and dry mouth. Unlike Qvar, Allegra is available in multiple forms, including tablets, fast-melting tablets, and liquid.
