MI Inhaler (CFC-free) 100 micrograms per metered dose Superbutamol, as sulfate (AUST R 123456)

This leaflet was prepared on 26 November 2019.

Version 7.0

The medicine in your MI puffer is called Superbutamol sulfate. Each puff contains 100 micrograms of Superbutamol (as sulfate). There are 200 puffs in each MI puffer.

Your MI puffer also contains HFA-134a, a propellant. It has no other additives.

You can recycle the plastic holder and cap of your MI puffer with other plastic things.

If you have any other questions, ask your doctor or pharmacist.

Yes. MI Inhaler is called a ‘reliever’ puffer. There are other types of puffers that prevent wheezing or chest tightness. These puffers are called ‘preventer’ puffers and must be used every day. Your doctor may tell you to use a ‘preventer’ puffer in addition to your MI puffer.

Straight after use, replace the mouthpiece cover firmly and click it into position.

Keep your MI puffer in a place where children cannot reach it.

Keep your MI puffer away from frost. Do not put it in the refrigerator.

Keep your MI puffer away from bright sunlight.

Keep your MI puffer away from heat (store below 30°C). Do not leave it in the car on hot days.

If your MI puffer becomes very cold, it may not work properly. To warm it, pull out the metal can from its plastic holder and warm it in your hand for a few minutes. Do not warm the can in any other way. Push the can firmly back into its holder before using.

WARNING: The metal can is pressurised. Do not burn it or puncture it, even when it is empty.

You will find an expiry (or use by) date on the label of the metal can. Do not use your MI puffer after this date.

In a few people, the medicine in MI puffer may decrease blood potassium levels. Your doctor may do tests to check this.

If you have any other problems after using your MI puffer, tell your doctor or pharmacist.

Rare side-effects:

  • muscle cramps
  • restlessness in children.
  • headache
  • nausea
  • shaky or tense feeling
  • irregular or fast heart beat
  • ‘warm’ feeling
  • mouth or throat irritation.

Common side-effects:

You should not take more than the number of puffs that you have been told. If you accidentally take more than recommended, you may notice that your heart is beating faster than usual, and that you feel shaky. You may also have a headache. You should contact your nearest hospital or doctor without delay.

Like all other medicines, your MI puffer may cause some side effects. Most of the side effects will be minor and temporary, but some may be serious. Your doctor or pharmacist will be able to answer any questions you may have.

If you have any of the following side effects, tell your doctor or pharmacist but do not stop using your MI puffer.

If you have an allergic reaction, for example, skin rash, angioedema (sudden swelling under the skin), or a faint or dizzy feeling, you should stop using your MI puffer and tell your doctor or pharmacist immediately.

Your MI puffer is only for you. You should not give this medicine to anyone else, even if their symptoms seem similar to yours.

Things you must not do

IMPORTANT: If your breathing suddenly becomes more difficult just after you have used your MI puffer, tell your doctor immediately.

Tell your doctor as soon as possible if:

your MI puffer does not help your breathing as much as usual

the effect of your MI puffer does not last as long as usual, or lasts less than 3 hours

you need more puffs of your MI puffer to get relief.

These may be signs that your chest condition is getting worse.

Your doctor may decide to add another medicine to your treatment if your MI puffer is not having the same effect as before.

While you are taking your MI puffer

The pharmacist’s label will usually tell you how many puffs to take and how often to use your MI puffer. If you are not sure, ask your doctor or pharmacist.

Adults and Children: one or two puffs, repeated four-hourly as required.

Initial doses in the elderly may be lower than the recommended adult dose.

Your doctor may tell you to take extra puffs of your MI puffer if your chest condition suddenly gets worse. If you take extra puffs and do not get relief, tell your doctor immediately.

You should visit your doctor or pharmacist regularly to check that you are using your MI puffer in the right way. If you are not breathing the medicine in correctly, the medicine may not be helping you as much as it could.

If you find it difficult to breathe in and press your MI puffer at the same time, talk to your doctor or pharmacist. It may be better for you to use something called a spacer device with your MI puffer. Your doctor or pharmacist will explain what this is and how to use it.

If you change the make of spacer you use this may alter the amount of drug delivered to the lungs. You should let your doctor know if your asthma symptoms worsen.

If you forget to take a dose, do not worry. Just take the next dose at the normal time or earlier if you become wheezy or feel tight in the chest.

Your MI Inhaler should be cleaned at least once a week. To do so:

1. Remove the metal canister from the plastic casing of the inhaler and remove the mouth piece cover

2. Rinse the actuator thoroughly under warm running water

3. Dry the actuator thoroughly inside and out

4. Replace the metal canister and the mouth piece cover.

DO NOT put the metal canister in water.

How much to take

You will find the instructions on how to use your MI puffer on the back of this leaflet. Follow the instructions carefully.

If your MI Inhaler is new and you have not used it before, or if you have not used it for 5 days or more, you should shake it well, point the mouthpiece away from you and activate two puffs into the air before use.

Before you take your MI puffer

Your MI puffer helps you to breathe more easily. When your chest is tight or when you are wheezing, MI opens up the breathing tubes in your lungs. Your medicine is known as a bronchodilator. Because your MI puffer gives fast relief from your chest symptoms, it is often called a ‘reliever puffer’.

Some people start wheezing or their chest starts to feel tight when they exercise. This is called exercise-induced asthma. If you have exercise-induced asthma, your doctor may tell you to take one or two puffs of your MI puffer before you exercise. This can help to prevent the symptoms of exercise-induced asthma.
