Antihistamine tablets can help to settle itch symptoms by blocking the action of histamine, one of the chemicals released by the body when the skin becomes inflamed.
Antihistamine tablets are generally well-tolerated but they can cause drowsiness in some patients. To reduce any potential effects of this, take this medication at night.
If you do experience drowsiness, do not drive or operate machinery - it is not safe!
Other potential side effects include dizziness, nausea and headache.
