Symbicort Uses, Dosage and Common Side Effects

Symbicort is an inhalation aerosol for relieving the symptoms of asthma and chronic obstructive pulmonary disease. It is an FDA approved bronchodilator application for the maintenance treatment of obstructive airways and is not intended for acute episodes of breathing trouble.

What are asthma and COPD?

Asthma is caused by environmental factors in genetically predisposed individuals, characterized by a cough, tightness in chest, wheezing and shortness of breath. The symptoms of asthma come in episodes that may vary in their frequency; usually, the condition worsens at night. The management of asthma includes avoiding the stimulants that trigger the asthmatic attacks and medications such as corticosteroid inhalers or in the severe cases intravenous route is used. Medicines for asthma come in two categories, the controls and the rescue ones for regular and urgent situation respectively.

Chronic Obstructive Pulmonary Disease is a collective term used for progressive diseases of lungs namely chronic bronchitis and emphysema, characterized by symptoms similar to those of asthma as shortness of breath, cough, wheezing, fatigue and frequent respiratory infections.

The management of COPD involves medications, pulmonary rehabilitation and in severe of cases, surgical intervention. The medications for COPD are mainly bronchodilators and anti-inflammatory drugs that dilate the airways and reduce inflammation therein, that may aggravate the symptoms of COPD. The drugs for this purpose are given as pills, inhalers or others.

In both the cases of asthma and COPD, early diagnosis and treatment are crucial for a better quality of life.

What is Symbicort?        

Symbicort is a combination of two medicines aimed at easing the breathing in patients with asthma and COPD, by

  • relaxation of airway  muscles (bronchodilation)
  • Reduction of any inflammation in the airways (anti-inflammatory)

The two medicines are Budesonide and Formoterol that is the steroid (anti-inflammatory) and the long-acting beta-2 adrenergic agonist (bronchodilator) respectively.

Final word on Symbicort

All the indications on Symbicort tell a fairy tale but

  • being a combination of steroid and LABA
  • with a boxed warning
  • various side effects
  • many drug interactions

There is growing skepticism on the use of asthma drugs containing LABA. These drugs have been shown to ‘mask’ the effects of asthma and in some cases have also revealed their addictive character. According to an article published in Huffington’s post, these drugs can cause ‘desensitization’ or toleranc e’ to ‘changing of the lung capacity over prolongs use’.

Always consult your physician before initiating any drug, go through the drug literature meticulously, and report any side effect promptly to authorities.
