Antihistamines are medicines that help stop the symptoms caused by allergies.
Itchy eyes, sneezing and runny noses may be helped by an antihistamine. Most antihistamines that must have a prescription are the non-sedating type. That means they won't make you sleepy. Non-sedating medicines are better for people who work with machinery or drive cars. When your doctor gives you a prescription, always ask if it's safe to use with the other medicines you're taking.
