Xyzal vs. Nasacort
See how Xyzal and Nasacort compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Xyzal is an oral antihistamine taken once daily, while Nasacort is a nasal spray corticosteroid used once daily in each nostril.
Xyzal treats both allergy symptoms and chronic hives, but Nasacort only targets nasal allergy symptoms.
Nasacort works locally in the nose with fewer systemic effects, while Xyzal can cause drowsiness because it works throughout the body.
Xyzal vs. Nasacort Drug Summary
Xyzal
Xyzal (levocetirizine) is a second-generation oral antihistamine that blocks histamine to relieve seasonal and perennial allergy symptoms and chronic hives. It comes as a tablet or oral solution taken once daily, usually in the evening because it can cause drowsiness. It has been available over the counter since 2017.
Nasacort
Nasacort (triamcinolone acetonide) is a corticosteroid nasal spray that reduces inflammation in the nasal passages to relieve seasonal and perennial allergy symptoms. It is sprayed into each nostril once daily and works directly at the site of irritation rather than throughout the body. It has been sold over the counter since 2013.

Xyzal vs. Nasacort Indications
Xyzal
Xyzal is FDA-approved for seasonal and perennial allergic rhinitis, easing sneezing, itching, and runny nose. It is also approved to treat the itching and hives of chronic idiopathic urticaria, an option Nasacort does not cover. This makes Xyzal a broader choice for people who deal with both allergies and chronic hives.
Seasonal allergic rhinitis symptoms
Perennial allergic rhinitis symptoms
Chronic idiopathic urticaria (hives) and itching
Approved for use as young as 6 months old
Nasacort
Nasacort is FDA-approved for the nasal symptoms of seasonal and perennial allergic rhinitis, such as congestion, sneezing, and runny nose. It is not approved for hives, asthma, or eye symptoms, so it works best for people whose main complaint is nasal congestion. It is approved for children as young as 2 years old.
Nasal congestion from seasonal allergies
Nasal congestion from perennial allergies
Sneezing and runny nose relief
Approved for use as young as 2 years old
Xyzal vs. Nasacort Pros and Cons
Xyzal
Xyzal offers once-daily oral dosing and covers both allergy symptoms and chronic hives, making it useful for people with overlapping conditions. Because it works systemically, it can cause drowsiness and interacts with alcohol and other CNS depressants. It also requires dose adjustments in kidney disease.
Pros
Also treats chronic hives, not just allergies
Oral tablet or liquid, no nasal spray technique needed
Approved for infants as young as 6 months
Often relieves symptoms within about an hour
Cons
Can cause drowsiness and fatigue
Must avoid alcohol and other sedating drugs
Dose must be adjusted for kidney impairment
Contraindicated in end-stage renal disease
Nasacort
Nasacort acts directly in the nasal passages, so it causes little to no drowsiness and has minimal systemic absorption. It only treats nasal allergy symptoms, not hives or skin reactions, and full relief can take several days of regular use to build up. Long-term use carries steroid-related risks like nasal irritation and slowed growth in children.
Pros
Little to no drowsiness or sedation
Minimal systemic absorption compared to oral pills
Simple once-daily spray dosing
Approved for children as young as 2 years
Cons
Does not treat hives or skin symptoms
Takes several days of regular use for full effect
Risk of nasal irritation, dryness, or nosebleeds
Long-term use may affect growth velocity in children
