What is Hydroxyzine?
Simply put, hydroxyzine is a type of medicine known as an antihistamine. When your body reacts to an allergy, it produces a natural chemical called histamine. Think of how a mosquito bite makes your skin itch, swell, and turn red because of histamine. This medicine works by blocking that histamine.
Doctors prescribe hydroxyzine liquid mainly for three common reasons:
- Allergies: It helps reduce itchy skin, hives, and rashes caused by allergic reactions.
- Anxiety: It calms your nervous system and helps you feel more relaxed when you feel very nervous or stressed.
- Before surgery: Doctors sometimes give it before a medical operation to help you relax and make you feel sleepy.
