Budesonide and Formoterol (Inhalation)

Known by the brand name Symbicort, budesonide and formoterol are combined to help improve lung function and control asthma symptoms in patients who did not respond well to other treatments.


Budesonide and formoterol are combined to create an inhaled corticosteroid that helps relax the lungs and relieve the symptoms of asthma. This medication is commonly known as Symbicort. It relaxes the muscles in the lungs to help prevent shortness of breath and wheezing. If you have not experienced relief from other asthma medications, this particular medication may be an option.

Symbicort is only available with a prescription from your doctor and is usually an alternative treatment to other more common types of asthma medications. This drug is also helpful with the treatment of chronic obstructive pulmonary disorder or COPD. It is available for use by both adults and children six years of age and older. Symbicort is only meant for use in patients who have severe asthma or COPD and is not well controlled through other forms of treatment.

Symbicort is not meant to be used as an emergency treatment if an asthma attack is already underway, but rather a daily preventative measure. This drug may increase the risk of death associated with asthma and should be used with caution under the supervision of your healthcare provider. If you have any pre-existing conditions or organ failure, you should discuss the benefits and risks of using this treatment with your doctor. You may not be a good candidate for this method of treatment if your pre-existing condition puts you at a high risk of side effects or organ failure.

It is important to closely monitor your mineral and bone density when using Symbicort. This medication may also impact your vision, so it is advised that you have regular vision screenings to help detect any changes in your vision. You should also rinse your mouth out after using this medication to help prevent thrush, which is a fungal infection. If, for some reason, you have a change in your lifestyle, increased stress, illness, or surgery, you may need to have your dose adjusted to compensate for these factors. If you decide to quit taking Symbicort, you should consult with your doctor about the proper method to taper off. It is not advised that patients quit taking this medication suddenly because they could suffer withdrawals.

Use caution when storing your Symbicort. Do not puncture the canister or store it where it will be exposed to heat or direct sunlight. Dispose of the unused portion if three months have passed since you punctured the foil seal on your canister. If you miss your dose of Symbicort, you should take it as soon as you remember. If it is time for your next dose, you should take the current dose only and resume your normal schedule. Do not double your dose if you miss one.

If you use steroids for an extended period of time, you may develop problems such as a marked increase in body fat, acne, impotence, loss of interest in sex, menstrual problems, thinning skin, and bruising easily. Once your asthma seems easily controlled, you may consider beginning the process of eliminating it from your daily routine. If you are pregnant or nursing you should refrain from using this medication because it is known to be harmful to developing and breastfeeding babies. Using Symbicort also increases your risk of infection. If you think you are at high risk for an infection, you should tell your doctor immediately.
