Duolin is a combination of two medicines, ipratropium and salbutamol, mixed together in a puffer or inhaler. The combination is used to treat conditions where breathing is a problem, such as COPD, chronic bronchitis and emphysema. They work by relaxing and opening up the air passages, making breathing easier and improving shortness of breath, chest tightness and wheezing.

Duolin belongs to a group of medicines known as bronchodilators or relievers (it is called a reliever medicine because it quickly relieves your breathing problems).

Using an inhaler device enables the medicine to go straight into your airways when you breathe in. This means that your airways and lungs are treated, but very little of the medicine gets into the rest of your body.

In Aotearoa New Zealand, Duolin® is available as an inhaler and nebulising solution. Nebulisers are used when using an inhaler is not suitable. The information on this page is about Duolin inhaler. Read more about nebulisers.

The usual dose of the Duolin inhaler is 2 puffs 4 times a day. You should not use more than 12 puffs in any 24 hour period.
Follow your doctor's instructions carefully. The pharmacy label on your medicine will tell you how much to use, how often to use it and any special instructions.

To get the most benefit, it is important to use the correct technique. Ask your doctor, pharmacist or nurse to explain how to use your inhaler. Even if you have been shown before, ask your doctor, pharmacist or nurse to explain again how to use your inhaler if you still have any questions. Here is some guidance.

How to use your MDI (puffer)
	Take off the cap and hold the inhaler upright.
	Shake the inhaler to mix the medication.
	Sit upright, tilt your head back slightly (as if you are sniffing) and breathe out gently.
	Hold the device upright, insert the inhaler into your mouth, ensuring that your lips firmly seal the mouthpiece. At the beginning of a slow, deep breath, breathe in through the mouthpiece as you press the inhaler to release one dose or 'puff'.
	Breathe in fully, remove the inhaler from your mouth and hold your breath for 10 seconds or as long as is comfortable. Breathe out gently through your nose.

Using a spacer with your inhaler

A spacer is an attachment to use with your MDI. Using a spacer with your MDI makes it easier to use the inhaler and helps to get the medicine into your lungs, where it’s needed (with less medicine ending up in your mouth and throat). Spacers improve how well your medicine works. Read more about spacers.
