What Is Loratadine?
Loratadine is an antihistamine.
It works by blocking histamine.
Histamine is a chemical your body releases during an allergic reaction.
When histamine is blocked, allergy symptoms become less severe.
Common Uses
Loratadine may help with:
- Seasonal allergies
- Hay fever
- Dust allergies

One of its biggest advantages is that it usually causes very little drowsiness.
That’s why many people take it before work or school.
What Is Cetirizine?
Cetirizine is also an antihistamine.
Like loratadine, it blocks histamine.
This helps reduce allergy symptoms.
Many people find cetirizine especially helpful during severe allergy seasons.
Common Uses
Cetirizine may help with:
- Pollen allergies
- Pet allergies
- Dust allergies
- Hives
- Skin itching
