}

Itulazax 12 SQ-Bet freeze-dried tablet
For adults. Standardized allergenic extract of birch pollen (Betula verrucosa).

1. What Itulazax Is And What It Is Used For

What Itulazax is

Itulazax contains allergenic extracts of birch pollen. The drug is in the form of freeze-dried tablets, which are like regular tablets but much softer and are absorbed into the body by placing them under the tongue.

What Itulazax is used for

Treatment of:

  • Allergic rhinitis
  • Conjunctivitis

caused by tree pollen from birch, alder, hazel, hornbeam, oak, and beech.

  • Allergic rhinitis is an inflammation of the nose that causes you to sneeze and get a stuffy nose or runny nose.
  • Conjunctivitis is an eye inflammation that makes the eyes red, itchy or runny.

Itulazax is used in adults.

Itulazax is prescribed by a doctor who has experience in treating allergies.

How Itulazax works

Itulazax increases the immune system’s tolerance to (your body’s ability to handle) tree pollen.

How does your doctor decide if Itulazax is right for you?

The doctor will investigate your allergic symptoms and perform a skin prick test and/or take a blood sample.
