A pharmacist is warning people with asthma that using a blue inhaler on its own this winter is a “serious red flag” and is urging them to speak to their doctor. Blue inhalers, medically known as short-acting beta2 agonists (SABAs), have long been essential for millions of people with breathing problems.
The reliever inhaler contains salbutamol (such as Ventolin) and provides immediate relief when someone is struggling to breathe. It works by quickly opening airways and relaxing muscles during asthma attacks, wheezing, coughing, or chest tightness caused by asthma or COPD.
However, technical advances mean official guidance now says people relying on the blue inhaler alone are no longer getting the best treatment for their condition. Pharmacist Raj R Patel, posting on TikTok as Pharmacist Health Raj, is warning people using the device that they may need to take action.
Pharmacist's warning on over-reliance
Raj explains: “If you're still using your blue inhaler on its own during the winter, that's now a red flag. I've been telling you this for ages as a pharmacist - blue inhalers like salbutamol work really fast. They open up your airwaves.”
“But most of you don't ever get told this. They don't treat the inflammation caused by your asthma, so you might feel better in the short term, but underneath, your asthma could be getting worse.”
Raj adds: “New Nice guidance links overuse with more hospital admissions, more attacks, and higher risk of death. If you need it more regularly, that's not normal asthma. That's full control.”
He advises: “Ask your doctor about combination inhaler, one that relieves the symptoms and one that treats the inflammation. Whatever you do, don't throw your inhaler away, but don't rely on it either.”
What is asthma?
Asthma is a long-term lung condition. It affects the airways that carry air in and out of the lungs, causing them to become swollen (inflamed). This makes the airways narrower so less air gets into and out of the lungs.
An estimated 7.2 million people living in the UK have asthma, according to Asthma + Lung UK - making it about eight in every 100 people. It causes symptoms like wheezing, breathlessness, a cough or a tight chest. Sometimes symptoms can get worse quickly. This is an asthma attack and can be triggered by a wide range of things including allergens, exercise or even changes in the weather.
Current NICE guidelines
NICE, the National Institute for Health and Care Excellence, currently recommends that patients switch from the traditional blue inhaler, which it says “masks the problem without fixing it”. Instead, it says they should use combination inhalers that don't just relieve symptoms but tackle the underlying inflammation that causes attacks in the first place.
Under current guidelines, those aged 12 and over who are newly diagnosed or need step-up treatment are expected to move to combination inhalers which use an inhaled steroid and a long-acting beta2 agonist (LABA) medicine called formoterol in a single device. They treat the inflammation and prevent flare-ups while also providing immediate relief.
NICE said those who have good control of their condition should rarely need their reliever - or rescue - inhaler and should be able to live normal lives with few or no symptoms. It also advises that overuse of the blue inhaler “is linked to a higher risk of attacks, hospital admissions and death”.
Specialist explains 'dangerous sign'
Figures show almost half of all blue inhaler users in England (48%) were prescribed more than two in 2024-2025. Specialists say this is a warning sign.
Dr Amina Al-Yassin, a GP and clinical lead for children and young people's services at Brent Integrated Care Partnership, said: “They make people feel better, but only briefly. We now know that over time, they are likely to make asthma worse. Seeing a blue inhaler used alone is now a dangerous sign to me.”
