What it is used for
- Hay fever (allergic rhinitis)
- Sneezing, runny or itchy nose
- Itchy, watery eyes
- Hives (urticaria) and itchy skin
- Other allergy symptoms from pollen, dust, or animals
How it works
Loratadine blocks the action of histamine, a substance the body produces during allergic reactions. This eases symptoms such as sneezing, itching, and a runny nose.
How it is taken
Available as tablets, dissolvable tablets, capsules, and a liquid syrup for children. It is taken by mouth, usually with or without food. Take it exactly as directed by your doctor, pharmacist, or the label, and avoid taking more than recommended.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
