What is this medication for?

Symbicort Turbuhaler® contains two medications: budesonide and formoterol.

Budesonide is an inhaled corticosteroid that helps to reduce and prevent swelling and inflammation in the airways. 

Formoterol is a long-acting beta-2 agonist (LABA) that keeps the airways open, helping you to breathe more easily. 

This combination medication is used to provide both quick symptom relief and long-term control of: 

  1. Asthma - a condition affecting the lungs which make it harder for the person to breathe as the airways become narrow and swollen.
  2. COPD - a long-term, progressive lung condition that makes it harder to breathe because airflow in and out of the lungs is partly blocked.

How should I take or use this medication?

Symbicort Turbuhaler® is usually called a "preventer" or "controller" inhaler. Do not stop taking your medication even if you feel well. In some cases, your doctor may advise you to use it as a "reliever" inhaler when symptoms suddenly get worse. If so, carry the Turbuhaler® with you at all times.
