It depends what you find easier to use, and which dose you need. They both do the same job, just in different ways. And the dosing is slightly different. Your clinician can help you decide which inhaler is best for you.
The active ingredients in Seretide Evohaler enter your lungs as a mist, and the same active ingredients are found in the Seretide Accuhaler in powder form.
The inhalers are both purple, but look different. The Evohaler is an ‘L’ shaped inhaler, and the Accuhaler is disk-shaped.
Some people find the Seretide Accuhaler easier to use because there’s no need to time your breathing as you take the dose of medicine.
The traditional aerosol inhaler (which is what Evohaler is a modern equivalent of) has been a popular form of treatment for asthma for over 50 years. Being easy to manufacture makes it highly affordable. Children and older people can find it difficult to time their breathing correctly when using an evohaler and this reduces the amount of medicine that reaches the lungs. Historically there has been concern about the environmental impact of aerosol inhalers and their effect on the ozone layer, [popover id=ref1] but many inhalers, including Seretide, are now made using CFC-free propellants.
