How to Use This Medicine:
- Your doctor will tell you how much medicine to use. Do not use more than directed.
- You will use this medicine with an inhaler device called a nebulizer. The nebulizer turns the medicine into a fine mist that you breathe in through your mouth and to your lungs. Your caregiver will show you how to use your nebulizer.
- When you have finished all your inhalations, rinse your mouth out with water.
- Primatene® Mist:
- Follow the instructions on the medicine label if you are using this medicine without a prescription.
- Before using the inhaler, activate it first by shaking then test spraying into the air away from your face 4 separate times.
- Shake and spray into the air once each time you take a dose.
- Remove the cap and look at the mouthpiece to make sure it is clean.
- 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 as long as you can.
- Release your finger and remove the inhaler from your mouth, then exhale slowly.
- If your symptoms are still not relieved after at least 1 minute, take a second inhalation.
- Wash your inhaler by removing the red cap and container. Run water through both ends of the mouthpiece for 30 seconds. Shake off as much water as you can. Air dry overnight. If you need to use the inhaler but it is still wet, shake off the excess water before using.
- The container of the inhaler contains a spray indicator. This will tell you how much medicine you have left. The spray indicator changes every after 20 sprays. Replace your inhaler as soon as the display reads "20".
- Children who use this medicine should be closely watched by an adult.
- Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
