Non‑Steroid Inhalers: What They Are and Why You Might Choose One

If you have asthma or COPD, you’ve probably heard the term "steroid inhaler" a lot. But there’s another class that gets less attention: non‑steroid inhalers. These devices deliver medicine that isn’t a corticosteroid, so they avoid some of the side effects that steroids can cause, like oral thrush or voice changes. Many people prefer them for mild‑to‑moderate symptoms or when a steroid isn’t needed.

Non‑steroid inhalers work by opening up the airways with bronchodilators. The most common ingredients are long‑acting beta‑agonists (LABAs) such as formoterol and vilanterol. They relax the smooth muscle around the bronchi, making it easier to breathe. Because they don’t reduce inflammation, you’ll still need a preventer inhaler if you have chronic symptoms, but a non‑steroid inhaler can give quick relief without the steroid baggage.

How Non‑Steroid Inhalers Work

When you press the inhaler, a fine mist of medication is released. You breathe it in, and the drug reaches the lungs within seconds. The bronchodilator binds to receptors in the airway walls, causing the muscles to loosen. This effect can start in as little as five minutes and lasts up to 12 hours, depending on the specific drug.

Because there’s no steroid involved, you won’t see the same risks of bone thinning, eye problems, or immune suppression that come with long‑term steroid use. However, non‑steroid inhalers can still cause a rapid heartbeat, trembling, or a slight headache. Most side effects are mild and go away if you use the inhaler as directed.

Breo vs Symbicort: Cost, Efficacy, and Dosing

Two of the most talked‑about non‑steroid inhalers are Breo and Symbicort. Both combine a LABA with a low dose steroid, but many users treat the LABA part as the main relief. In 2025, Breo (fluticasone/formoterol) and Symbicort (budesonide/formoterol) are priced similarly, but the exact cost depends on your pharmacy and insurance.

In terms of efficacy, studies show they’re pretty much neck‑and‑neck for improving lung function. The key difference is the steroid component: Breo’s fluticasone is slightly stronger, while Symbicort’s budesonide is a bit gentler. If you want a true non‑steroid option, look for inhalers that list only formoterol or vilanterol without any steroid.

Typical dosing is two puffs twice a day. Some people can manage with one puff twice daily if their symptoms are mild. Always follow your doctor’s instructions – over‑using a LABA can lead to tolerance and make the inhaler less effective.

When you’re buying these inhalers online, stick to reputable UK pharmacies that require a prescription. Check for a valid pharmacy licence, read customer reviews, and compare prices. Avoid sites that promise "no prescription needed" – they’re likely selling counterfeit products.

To sum up, non‑steroid inhalers give solid relief with fewer steroid‑related side effects. Know how they work, compare popular options like Breo and Symbicort, and shop safely online. With the right inhaler and proper use, you’ll breathe easier without the extra hassle of steroids.
