What is Loratadine?

Loratadine is an antihistamine medicine that treats the symptoms caused by hay fever or an allergic reaction. 

How does Loratadine work?

Loratadine works by blocking the production of histamine within the body. When you come into contact with something you are allergic to, like pollen, dust or pet hair, histamine is produced by cells in your body. Histamine causes symptoms like a runny nose, itchy eyes, sneezing or rashes. An antihistamine stops histamine from being released to ease or prevent these symptoms.


How to take Loratadine?

You should only take Loratadine when you come into contact with an allergen, or if you expect to, for example during the high pollen season. Take Loratadine once a day during these periods in either tablet or liquid form. If you are taking tablets, these should be swallowed whole with a drink of water or juice. Do not crush or chew the tablets. The ‘melt in the mouth’ tablet dissolves on the tongue without needing a drink. Take care not to crush the tablets as you pop them out of their packaging.

Side Effects

Can I take Loratadine with other hay fever treatments?

You can take Loratadine with other hay fever treatments such as nasal sprays and eye drops. Do not take more than one type of antihistamine unless your doctor has advised you to do so.

How can I cope with Loratadine side effects?

Loratadine is a non-drowsy antihistamine, but it can cause drowsiness in some people. If you experience drowsiness, you may wish to try a different non-drowsy medicine. Ask your doctor for a suitable alternative. Try drinking water and take painkillers if you get headaches. If feelings of tiredness or nervousness persist, then let your doctor know.

Will it affect my contraception?

Loratadine does not affect any method of contraception.
