There are different types of budesonide inhalers and one of them is Pulmicort Flexhaler. It's very important to use your inhaler properly so that you get the right amount of budesonide into your lungs and the most benefit from your medicine. Read the information leaflet that comes with the product before using the inhaler. In the leaflet, you can find some instructions and diagrams to show you how to use the inhaler correctly, including how to keep it clean (to prevent infections) and how long can you use it before needing a replacement. Here is the step-by-step guide on how to use the Pulmicort Flexhaler: Turn the protective cover and lift it off. If this is your first time using a new Pulmicort Flexhaler, you must prime it by twisting the brown grip fully to the right as far as it gets, before twisting it back again fully to the left. Then, you will hear a click. Repeat. Priming only applies to a new inhaler. You don’t need to do this again even if the inhaler hasn’t been used for a long time. Check that you are using the correct strength as prescribed by your doctor. The dosage is based on your medical condition and response to treatment. Breath out, then inhale the medication by mouth. While inhaling, breathe calmly and deeply (around 10 seconds) until the mist stops. Put the protective cap back on and twist to shut it. Always keep the inhaler clean and dry with the cover in place in the upright position (mouthpiece on top). After each treatment, rinse and gargle your mouth with water to prevent dry mouth,thrush and hoarseness. Don’t swallow the rinse water. Wash your face/the area where the mouthpiece of the inhaler has touched your skin to prevent skin reactions and irritation. Avoid getting the medication in your eyes.
