What is loratadine, and what is it used for?
Loratadine is an antihistamine used to treat allergy symptoms. It helps reduce symptoms such as sneezing, runny nose, itchy nose, and itchy or watery eyes from hay fever (seasonal allergies) and other allergic reactions.
How does loratadine work?
Loratadine blocks histamine at H1 receptors. Histamine is one of the key chemicals your body releases during allergy responses, so blocking it helps lessen allergy symptoms.
How long does loratadine take to work, and how long does it last?
Loratadine is typically taken once daily. It generally starts working within a few hours, and its effect can last throughout the day.
What side effects do people report with loratadine?
Common side effects can include headache, dry mouth, and tiredness or drowsiness in some people. If you experience severe allergic reactions (such as swelling of the face/lips, trouble breathing, or widespread hives), seek emergency care.
Is loratadine “non-drowsy”?
Many people experience little or no drowsiness, but drowsiness can still occur. Avoid driving or operating machinery until you know how it affects you.
How do you take loratadine safely?
Follow the label or your clinician’s instructions for dose and frequency. If you have liver disease, ask a clinician because the usual dosing may need adjustment. Also check with a pharmacist if you take other medications to make sure there are no important interactions.
Loratadine vs. cetirizine or fexofenadine—what’s the difference?
All are allergy antihistamines, but people often notice differences in drowsiness and side-effect profiles. Loratadine is commonly described as less likely to cause sleepiness than some alternatives, though individual responses vary.
Is loratadine prescription-only or available over the counter?
In many places, loratadine is available over the counter for typical allergy symptom treatment, and prescription versions may also exist depending on local regulations.

What should you do if symptoms don’t improve?
