1. What Hydroxyzine Orifarm is and what it is used for

What is Hydroxyzine Orifarm?

Hydroxyzine Orifarm belongs to a group of medicines called sedative antihistamines. It suppresses certain functions in the brain without being addictive. It also blocks histamine, a substance found in the body’s tissues that causes allergic reactions.

What is it used for?

Hydroxyzine Orifarm is used to treat:

  • anxiety in adults, where other drugs are not suitable
  • hives and itching caused by allergic reactions

In case of anxiety, the effect is felt after about 15 minutes and lasts for about 12 hours. With itching and hives, the effect is reached after about 1 hour and lasts at least 24 hours.

Hydroxyzine hydrochloride contained in Hydroxyzine Orifarm may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
