Claritin vs. Nasacort
See how Claritin and Nasacort compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Claritin is an oral antihistamine that treats sneezing, itching, and hives throughout the body, while Nasacort is a nasal spray steroid aimed mainly at nasal congestion and stuffiness.
Nasacort tends to work better for nasal congestion specifically, while Claritin also covers itchy eyes, throat symptoms, and chronic hives that a nasal spray cannot reach.
Both are available over the counter and are taken once daily, but Nasacort can take several days to reach full effect while Claritin often works within hours.

Claritin vs. Nasacort Pros and Cons
Claritin
Claritin offers whole-body relief from allergy symptoms and is the only one of the two approved for chronic hives. It causes little sedation for most users but tends to be less effective than a nasal steroid when congestion is the main complaint.
Pros
Also approved for chronic hives and itching, not just allergies
Relieves itchy eyes and throat that a nasal spray cannot reach
Available as tablet, dissolving tablet, chewable, or syrup
Often noticeably works within a few hours
Cons
Generally less effective for nasal congestion than a steroid spray
Some people still experience drowsiness or fatigue
Does not treat local nasal inflammation directly
Not approved for common cold symptoms or asthma
Nasacort
Nasacort targets nasal inflammation directly, which often makes it more effective for stuffiness than an oral antihistamine. Because it works locally, systemic side effects are less common, though it needs to be used consistently for several days to reach full effect.
Pros
Often more effective than antihistamines for nasal congestion
Acts locally in the nose, limiting systemic side effects
Available in a lower maintenance dose once symptoms improve
First OTC nasal steroid spray with long track record of use
Cons
Can take several days of regular use for full effect
May cause nosebleeds or nasal irritation
Not approved for hives or itching outside the nose
Not approved for children under 2 years of age
