About Symbicort

Symbicort is an inhalation medicine. It contains two active ingredients:

  • Formoterol. This medicine works by relaxing the muscles in your airways. This helps you breathe more easily. Formoterol belongs to a group of medicines called long-acting bèta 2‑adrenoceptor agonists.
  • Budesonide. This anti-inflammatory medicine protects the lungs from asthma triggers. Budesonide belongs to a group of medicines called corticosteroids (adrenal cortex hormones).

Symbicort is prescribed by doctors to provide relief from symptoms of asthma and chronic obstructive pulmonary disease (COPD), such as chest tightness, wheezing and coughing. Symbicort can be used for relief of acute asthma symptoms and/or to prevent asthma symptoms from happening. The doctor will tell you how you need to use this medicine.

How to use Symbicort

Symbicort is inhaled. To prevent asthma symptoms from happening, it is important to use Symbicort every day, even if you have no asthma symptoms at the time.

You can also use Symbicort to treat your symptoms when they happen. You doctor may also describe a different medicine to help manage your asthma.

There are various Symbicort inhalers, including the Turbohaler. See the package leaflet provided with Symbicort Turbohaler for step-by-step instructions on how to use this inhaler. Follow these instructions closely. The general guidelines for use are:

  • Prepare your Turbohaler for use according to the instructions in the package leaflet.
  • Remove the dustcap.
  • Hold your Turbohaler upright with the red grip at the bottom.
  • Do not hold the mouthpiece when you load your Turbohaler. To load your Turbohaler with a dose, turn the red grip as far as it will go in one direction. Then turn it as far as it will go in the other direction. You should hear a click sound. Your Turbohaler is now loaded and ready to use. Only load your Turbohaler when you need to use it.
  • Breathe out gently as far as comfortable. (Do not breathe out through your Turbohaler.)
  • Place the mouthpiece gently between your teeth. (Do not bite on the mouthpiece.) Close your lips. Breathe in as deeply and hard as you can through your mouth.
  • Remove the Turbohaler from your mouth. Then breathe out gently (not through the mouthpiece).
  • If you are to take a second inhalation, repeat the above steps.
  • Rinse your mouth with water after the dose and spit it out. This will prevent irritation in your mouth and throat.
  • Replace the cover by screwing it back on tightly after use.


Symbicort is available in various strengths. Strength, the number of inhalations and inhalation frequency must be determined by a doctor.


This medicine does not interact with alcohol and will normally not affect your ability to drive or operate machinery.
