Loratadine is a popular antihistamine commonly used to relieve allergy symptoms such as a runny nose, sneezing, itchy or watery eyes, and itching of the throat or nose.
It is often prescribed for seasonal allergic rhinitis (hay fever), hives, and other allergic conditions. Unlike some older antihistamines, loratadine is a second-generation antihistamine, which means it causes fewer sedative effects, making it suitable for daily use.

What Is Loratadine and How Does It Work?
Loratadine is an antihistamine, a type of medication that blocks the effects of histamine, a substance your body releases during allergic reactions.
Histamine causes many of the symptoms of allergies, including itching, swelling, and increased mucus production. By blocking histamine receptors, loratadine helps reduce these allergic reactions and provides relief from symptoms such as:
- Sneezing
- Itchy or watery eyes
- Runny nose
- Itchy throat
- Hives (urticaria)
Unlike older antihistamines, loratadine is a second-generation antihistamine, which means it does not easily cross the blood-brain barrier and is less likely to cause drowsiness. This makes it ideal for individuals who need to maintain focus during daily activities.

Uses of Loratadine
Loratadine is primarily used to treat symptoms associated with allergic conditions. Some of its common uses include:
- Seasonal Allergic Rhinitis (Hay Fever):
It helps relieve the typical symptoms of hay fever, such as sneezing, nasal congestion, and itchy or watery eyes, which occur during allergy season. - Perennial Allergic Rhinitis:
For people with year-round allergies, loratadine is effective in controlling symptoms triggered by allergens such as dust mites, pet dander, or mold. - Hives (Urticaria):
Loratadine can help reduce itching and the formation of hives, which are raised, red, itchy welts on the skin. - Itching:
For people who experience itching from allergic reactions, loratadine helps reduce the severity of these symptoms.
How to Use Loratadine
Loratadine is available in several formulations, including tablets, syrup, and disintegrating tablets. The medication is typically taken once daily.
1. Tablets:
- Swallow the tablet whole with or without food.
- The typical dose for adults and children over 6 years is 10 mg once a day.
- Do not exceed the recommended dose, as this can lead to side effects.
2. Syrup:
