Usage Steps:
Before the first use of the metered-dose inhaler or if it hasn't been used for several days, perform a test spray into the air to ensure it can be used, depending on the specific product.

Without Spacer Device:

1. Remove the protective cap and attach the extension tube.
2. Shake the inhaler thoroughly before use.
3. Hold the inhaler (bottom facing up, index finger on the base).
4. Exhale slowly.
5. Place the mouthpiece of the inhaler in your mouth, close your lips around it, but do not bite.
6. Inhale slowly through your mouth while pressing down on the base of the inhaler to release the medication spray. Maintain a steady and deep inhalation.
7. Remove the inhaler from your mouth, close your lips, and hold your breath for 5 to 10 seconds.
8. Exhale gently and resume normal breathing.
9. If a second dose is required, wait 1 to 2 minutes before repeating steps 2 to 8.
10. Replace the protective cap after use.

Using a Spacer Device:

1. Remove the protective cap.
2. Connect the wider end of the spacer device to the inhaler's mouthpiece.
3. Attach the protective cap to the narrower end of the spacer device.
4. Shake the inhaler vigorously while ensuring a secure connection.
5. Use your index finger to press down on the inhaler's base as directed by your physician. Confirm that medication is sprayed into the spacer device.
6. Exhale, then remove the protective cap and immediately start inhaling at a normal pace from one end of the spacer device.
7. Once the medication in the spacer device is fully inhaled, remove the inhaler from your mouth, close your lips, and hold your breath for 5 to 10 seconds.
8. Remove the spacer device and replace the protective cap.
9. Clean the spacer device regularly with warm water and let it air dry.

Usage Precautions:

• Except for Alvesco asthma inhaler, ensure thorough shaking before each use.
• Do not forcefully open the inhaler as it contains pressure. Store at room temperature (not above 50°C or 122°F).
• Plastic mouthpieces are designed for use with specific metered-dose liquids and should not be interchanged.
• After using steroids-containing medication, rinse your mouth to prevent oral candidiasis.
• Children or the elderly may use a spacer device to assist with inhalation.

Cleaning:

• Clean the nozzle and mouthpiece with dry tissue or cloth at least once a week to prevent blockage. Do not wash with water or submerge in water.
• If blocked, clean the nozzle and use a fine needle to clean the spray nozzle and inlet.
• Determining Remaining Medication:
• Berotec® N 200 MDI and Berodual® N 200 MDI: Place the canister in water and judge based on its suspension.
• Seretide™ Evohaler 250 and Seretide™ Evohaler 125: Do not place the canister in water. Check the scale on the inhaler to determine the remaining amount.
• Foster and Alvesco: Mark the opening date on the bottle to calculate the remaining medication.
