What is loratadine (and is it a prescription medicine)?
Loratadine is an antihistamine medicine used to treat allergy symptoms. It is typically sold over the counter (OTC) for adults and children, depending on the product and age guidance.
What does loratadine treat?
Loratadine is commonly used for:
- Allergic rhinitis (hay fever), including sneezing, runny nose, and itchy/watery eyes
- Other allergy symptoms approved on the specific product label
How does loratadine work?
Loratadine blocks histamine (a chemical the body releases during allergic reactions), which helps reduce allergy symptoms.
Does loratadine cause drowsiness?
Loratadine is often described as a “non-drowsy” or “less drowsy” antihistamine compared with older allergy medicines, but some people can still feel tired or sleepy. Product directions advise paying attention to how it affects you before driving or using machinery.
Brand names and common product types
Loratadine is sold under multiple brand names and also as generics, depending on the country. If you tell me your country or the exact package name, I can help identify the specific brand/product you have.
Important safety notes
Follow the dosing instructions on the package or from a clinician. If you’re pregnant, breastfeeding, have liver disease, or are giving it to a child, dosing guidance can differ by age and health status.
