Xyzal vs. Flonase
See how Xyzal and Flonase compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Xyzal is an oral antihistamine that calms itching, sneezing, and hives from the inside, while Flonase is a nasal steroid spray that reduces inflammation directly in the nose.
Flonase tends to work better for nasal congestion, while Xyzal can be more useful for itchy eyes, skin, and chronic hives.
Both drugs are available over the counter, so many people can try either without a prescription.
Xyzal vs. Flonase Drug Summary
Xyzal
Xyzal is an oral antihistamine (levocetirizine) that blocks histamine to relieve sneezing, itching, and runny nose from seasonal and year-round allergies. It also treats itchy skin from chronic idiopathic urticaria. It comes as a tablet or oral solution taken once daily, usually in the evening.
Flonase
Flonase is a nasal corticosteroid spray (fluticasone propionate) that reduces inflammation inside the nasal passages to relieve congestion, sneezing, and runny nose.

Xyzal vs. Flonase Pros and Cons
Xyzal
Xyzal works throughout the body, which makes it useful for itchy eyes, skin, and hives in addition to nasal symptoms. It can cause drowsiness in some people and requires dose adjustments for kidney problems.
Pros
Also relieves itchy eyes and skin, not just nasal symptoms
Approved for chronic hives, unlike Flonase
No local nasal side effects like irritation or nosebleeds from the spray itself
Available as a liquid oral solution for those who dislike pills
Cons
Can cause drowsiness, so timing around driving matters
Contraindicated in severe kidney impairment and dialysis patients
Generally less effective than a nasal steroid for congestion
Should not be combined with alcohol or other sedating drugs
Flonase
Flonase acts directly on nasal tissue, which often makes it more effective for stuffiness than an oral antihistamine. It does not cause the drowsiness antihistamines can, but it carries its own local risks with long-term use.
Pros
Often more effective for nasal congestion than an oral antihistamine
Does not cause systemic drowsiness
Once-daily maintenance dosing after the initial titration
Also approved for nonallergic rhinitis
Cons
Can cause nosebleeds, nasal irritation, or nasal ulceration
Carries a risk of Candida (yeast) infection in the nose or throat
Not approved for chronic hives or itchy skin
Long-term pediatric use requires monitoring for growth effects
