Acrivastine is an antihistamine medicine that helps the symptoms of allergies.
It helps to treat:
- symptoms from hay fever
- conjunctivitis (red, itchy eyes)
- eczema
- hives (urticaria)
- reactions to insect bites and stings
- some food allergies
Acrivastine is a non-drowsy antihistamine. It's less likely to make you feel sleepy than some other antihistamines.
Acrivastine comes as capsules and is available on prescription. You can also buy smaller packs from pharmacies and supermarkets.
Sometimes it's combined with a decongestant called pseudoephedrine to unblock your nose and sinuses.
