Frequently asked questions

Below are answers to some commonly asked questions about Pulmicort and its dosage.

How does the dosage of Pulmicort compare with the dosage of Symbicort?

Symbicort contains two drugs. One is the same active ingredient in Pulmicort (budesonide). It also contains another drug called formoterol.

The recommended dosage of Symbicort is two inhalations twice daily. The specific dosage will depend on how severe your asthma is. Talk with your doctor for specific dosing information about Symbicort.

The number of inhalations and how often you will use Pulmicort depends on your age, how severe your condition is, and other factors. See the “Dosage of Pulmicort” section above and talk with your doctor for more information.

Is Pulmicort used long term?

Yes, doctors typically prescribe Pulmicort as a long-term treatment. If you and your doctor determine that it’s safe and effective for your condition, you’ll likely use it long term. Pulmicort is a maintenance treatment for asthma. This means it should be used daily to help prevent an asthma attack.

If you have questions about how long you should use Pulmicort, talk with your doctor.

How Pulmicort is used

You’ll inhale Pulmicort once or twice per day using the Flexhaler or a nebulizer.

Pulmicort should be used daily to help prevent an asthma attack. Do not use Pulmicort to treat a sudden asthma attack. Pulmicort is not a rescue inhaler.

Your doctor will show you how to use Pulmicort Flexhaler or Pulmicort Respules (for use with a nebulizer with an air compressor and a face mask/mouthpiece). You should rinse your mouth with water and spit out the water (do not swallow) after each dose. This will help prevent you from getting a fungal infection called thrush.

Also, be sure to talk with your doctor or pharmacist if you’re having difficulty using your medication. They can offer recommendations about taking it.
