2. Breathe in through the mouthpiece of the inhaler to obtain pain relief. Your healthcare professional will show you how if you are unsure. Accustom yourself to the fruity smell of the medicine by inhaling gently for the first few breaths. Breathe out through the Inhaler. After the first
few breaths breathe normally through the inhaler

Information for Healthcare Professionals
The following information is intended for healthcare professionals only: Instructions on the preparation of the Penthrox® Inhaler and correct administration are provided in the Figures below:
1. Ensure the Activated Carbon (AC) Chamber is inserted into the dilutor hole on the top of the Penthrox® Inhaler.
2. Remove the cap of the bottle by hand. Alternatively, use the base of the Penthrox® Inhaler to loosen the cap with a V turn. Separate the Inhaler from the bottle and remove the cap by hand.
3. Tilt the Penthrox® Inhaler to a 45° angle and pour the total contents of one Penthrox® bottle into the base of the Inhaler whilst rotating.
4. Place wrist loop over patient’s wrist. Patient inhales through the mouthpiece of the Penthrox® Inhaler to obtain analgesia. First few breaths should be gentle and then breathe normally through Inhaler.
Patient exhales into the Penthrox®
Inhaler. The exhaled vapour passes through the AC Chamber to adsorb any exhaled methoxyflurane.
If stronger analgesia is required, patient can cover dilutor hole on the AC chamber with finger during use.
Patient should be instructed to inhale intermittently to achieve adequate analgesia. Continuous inhalation will reduce duration of use. Minimum dose to achieve analgesia should be administered.
Replace cap onto Penthrox® bottle. Place used Penthrox® Inhaler and used bottle in sealed plastic bag and dispose of responsibly.
