What is Symbicort (budesonide/formoterol)?
Symbicort (budesonide/formoterol) is an FDA-approved medication manufactured by AstraZeneca used to treat asthma in adults and children aged 12 and over. It is also used to improve symptoms of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema in adults.
Asthma is an inflammatory disease of the lungs and airways; it can cause your chest to tighten and make it difficult to breathe. COPD is a condition that also affects the lungs and makes it hard to breathe. Symbicort assists with both of these conditions by reducing inflammation and by relaxing the muscles in the lungs and airways. This helps to reduce the feeling of tightness in your chest and makes it easier for you to breathe.
Symbicort contains two active ingredients: budesonide and formoterol fumarate dihydrate. Formoterol fumarate dihydrate is a long-acting beta-agonist (LABA), and a bronchodilator, and relaxes the muscles in your airways, making it easier to breathe. Budesonide is an inhaled corticosteroid (ICS) that reduces inflammation in the lungs. When both are used in combination, they reduce the incidence of asthma symptoms and can help manage the symptoms of chronic obstructive pulmonary disease.

Symbicort is available as a metered-dose inhaler in the following doses: 80 mcg/4.5 mcg per actuation, 160 mcg/4.5 mcg per actuation.
Symbicort comes as a dry powder that is inhaled using an inhaler device called a Turbohaler. You usually take the medicine once a day to prevent symptoms from occurring. It can be taken as a preventative measure before an activity that causes you breathing problems.
Symbicort is not a rescue treatment for asthma attacks or bronchospasm. Use only fast-acting inhalation medicine for an asthma attack. Seek medical attention if your breathing problems get worse, or if you think your medications are not working.
Rinse your mouth with water after each use of your Symbicort inhaler. This will reduce the chances of developing sore throats or oral thrush. If you miss a dose, skip the missed dose and take your next dose at the normally scheduled time. Do not double your doses.
Store your Symbicort Turbuhaler at room temperature in an upright position, with the mouthpiece down. Keep away from heat or an open flame. Discard the canister once the counter reads 0 (zero), or if you have been using this particular Turbohaler for longer than 3 months.
Read the medication guide provided with this medicine for the full drug information, and always speak with your healthcare provider for medical advice about any changes to your dose so they can monitor and evaluate your condition.
