Upsides

  • Combines two medicines in one inhaler.
  • Can be used long-term and causes fewer side effects than other oral treatments that are sometimes used to treat asthma.
  • Prevents symptoms and improves lung function in children and adults with chronic asthma.
  • A single 10 mg dose improves exercise-induced asthma symptoms for up to 24 hours.
  • Fewer side effects compared to other asthma treatments.
  • Also relieves nasal allergy symptoms.

Downsides
  • Can cause infections in your mouth and throat, so you need to rinse your mouth with water after using it each time.

  • People with COPD need to use the higher dose of Symbicort (budesonide / formoterol).
  • This drug can't be used as a rescue inhaler if you get an asthma attack. It can only be used for the daily management of asthma and COPD.
  • You have to use Montelukast every day to control your symptoms.

  • There's no generic available, so it can be expensive.
