How should I use Pulmicort Flexhaler?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Pulmicort Flexhaler is not a rescue medicine. It will not work fast enough to treat an asthma attack. Use only a fast acting inhalation medicine for an asthma attack.
This medicine comes with a medication guide for safe and effective use, and directions for priming and cleaning the inhaler device. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
Use only the inhaler device that comes with your medicine. Do not place the Pulmicort Flexhaler device in water or try to take it apart.
Always rinse your mouth with water after using this medicine, to help prevent thrush (a fungal infection in the mouth or throat). If you are using a nebulizer with a face mask, wash the mask area of your face after each use.
While using budesonide, your doctor may need to check your vision and bone mineral density.
Using a steroid can weaken your immune system. This can make it easier for you to get sick from being around others who are ill.
Call your doctor if your symptoms do not improve after the first week of treatment, or if you think your asthma medications are not working as well. If you use a peak flow meter at home, tell your doctor if your numbers are lower than normal.
Asthma is usually treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.
Store at room temperature, away from moisture, light, and heat. Keep the cover on your inhaler device while not in use.
Store Pulmicort Respules upright in the foil envelope. When you are ready to use the medicine, remove an ampule and put the strip back in the envelope. Once you have opened an envelope, you must use the ampules within 2 weeks.
The Pulmicort Flexhaler device has a dose counter that shows how many doses are left inside. The dose-counter indicator may not appear to move until about 5 doses have been used. Do not use an extra dose just because the Flexhaler indicator has not moved to a lower number after just one use.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
An overdose of Pulmicort Flexhaler is not expected to produce life threatening symptoms. Using too much of a steroid long-term can lead to symptoms such as: thinning skin, easy bruising, changes in the shape or location of body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.
What should I avoid while taking Pulmicort Flexhaler?
Avoid getting this medicine in your eyes.
Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using Pulmicort Flexhaler.
