A marathon runner is backing a campaign urging asthma patients to get their inhaler technique checked by a GP or nurse.

Paul Wilson, from North Ayrshire, ended up in hospital 48 times with asthma issues and had to be resuscitated on 25 occasions.

The 44-year-old missed out on vital inhaler technique checks with his GP because he missed his yearly asthma reviews.

But last year Paul, who is backing the Asthma UK campaign, managed to complete the London Marathon after life-saving advice from an asthma nurse.

He says: "I've been rushed to hospital countless times with my asthma, and been put on drips, nebulisers, and even ended up in intensive care.

"But I'd never really given too much thought on how to manage my asthma or use my inhaler properly. Looking back, I was just taking a puff and hoping for the best.

"My symptoms were getting so severe that it got to the point where I was having an asthma attack every week. I would wake up in the middle of the night gasping for breath and it felt like someone was sitting on my chest.

"I realised I needed help and booked an appointment with my asthma nurse for a medication review. They said the way I was using my inhaler meant that only 10-20% of the medicine was getting into my lungs.

"They showed me the correct inhaler technique and gave me a spacer to use, and the difference it has made to my asthma is incredible- I even ran the London Marathon for Asthma UK last year.

"I never thought that something so simple could completely turn my life around."

Nearly one in five people aren't getting their inhaler technique checked, according a new report by Asthma UK, which included a survey of more than 10,000 people.

The charity is now calling on doctors, asthma nurses and pharmacists to help patients avoid asthma attacks by supporting them with their inhaler technique

Dr Andy Whittamore, clinical lead at Asthma UK and a practising GP, said: "Inhalers are the bread-and-butter treatment for most people with asthma, so it's really worrying that many people are not taking them properly, or getting their technique checked by their GP or asthma nurse.

"With so many different types of inhaler which are all used in different ways, it can be difficult for patients and healthcare professionals to know the correct way to use them.

"It's also easy for patients to get into bad habits or simply forget the best technique following their appointment, especially if they have a new type of inhaler.

"But even a small tweak to how someone uses their inhaler can make a huge difference and could prevent them having a life-threatening asthma attack.

"We're urging people with asthma and healthcare professionals to watch Asthma UK's videos so they feel confident in how people can use their inhalers to stay well."
