How to Use This Medicine:
Powder Under Pressure
- Take your medicine as directed. Your dose may need to be changed several times to find what works best for you.
- You will use this medicine with a device called a metered-dose inhaler. The inhaler fits on the medicine canister and turns the medicine into a fine spray that you breathe in through your mouth and to your lungs. You may be told to use a spacer, which is a tube that is placed between the inhaler and your mouth. Your caregiver will show you how to use your inhaler and the spacer (if needed).
- Do not remove the canister from the actuator.
- Remove the cap and look at the mouthpiece to make sure it is clean.
- Prime the inhaler: Before you use an inhaler for the first time, prime it by pointing it away from your face and spraying into the air 4 times. If the inhaler has not been used for 5 days or longer, prime it again.
- Always shake the inhaler right before you spray it, every time.
- To inhale this medicine, breathe out fully, trying to get as much air out of the lungs as possible. Put the mouthpiece just in front of your mouth with the canister upright.
- Open your mouth and breathe in slowly and deeply (like yawning), and at the same time firmly press down on the top of the canister once.
- Hold your breath for about 5 to 10 seconds, and then breathe out slowly.
- If you are supposed to use more than one puff, wait 1 to 2 minutes before inhaling the second puff. Repeat these steps for the next puff, starting with shaking the inhaler.
- When you have finished all your inhalations, rinse your mouth out with water. Do not swallow the water.
- Clean the inhaler mouthpiece daily with warm water.
- This medicine should come with a Medication Guide. Ask your pharmacist for a copy if you do not have one.
- Missed dose: Take a dose as soon as you remember. If it is almost time for your next dose, wait until then and take a regular dose. Do not take extra medicine to make up for a missed dose.
- Store the canister at room temperature, away from heat and direct light. Do not freeze. Do not keep this medicine inside a car where it could be exposed to extreme heat or cold. Do not poke holes in the canister or throw it into a fire, even if the canister is empty. Store the inhaler that has 60 doses with the mouthpiece down or sideways.
- Dispose of the inhaler when the counter reads "0" even if it feels like it still has medicine in it.
