Can a steroid inhaler cause bruising?

By Margaret Hale, Reunoa EditorialLast updated October 26, 2026

Steroid inhalers (inhaled corticosteroids, ICS) such as fluticasone, budesonide, beclomethasone and mometasone are cornerstones of asthma and COPD treatment. Most of the medicine stays in the lungs, but a small amount is absorbed into the body — enough, over years, to affect the skin in some people.

What the research shows

The clearest data comes from the Lung Health Study II, a randomized trial in people with COPD. Every six months, participants were asked about skin changes ^[1]:

• Easy bruising: 11.2% with the inhaled steroid vs 3.5% with placebo (among those who used their inhaler consistently)
• Slow healing of cuts or sores: 2.4% vs 0.5%
• Older men with good adherence appeared to be at the highest risk

So, most people on steroid inhalers do not notice extra bruising — but it is roughly three times as common as without.

Who is more at risk

• higher doses, especially of the more potent inhaled steroids
• years of use
• older age and sun-damaged, thin skin
• also taking steroid tablets for flares ^[2]
• also taking blood thinners or aspirin

Should you stop your inhaler?

No. Inhaled steroids prevent flare-ups and hospital stays. Stopping them can be risky. Instead, ask your doctor or respiratory nurse:

• Is my dose the lowest that keeps my symptoms controlled?
• Is my inhaler technique right? (Better technique means more goes to the lungs.)
• Would a spacer help?
• Do I still need the steroid component, or would another option suit me?

Protecting your skin

1. Moisturize forearms and hands twice a day — it halved skin tears in older adults in a trial ^[4].
2. Long sleeves for chores and gardening.
3. Sunscreen on forearms and hands.
4. Pad corners at home.
5. Rinse your mouth after each dose (this helps prevent thrush; it doesn't affect skin).

Steroid-related skin thinning is mostly linked to chronic, long-term exposure ^[3]. More: steroid skin thinning.

Inhaler technique tips

Better technique means more medicine reaches the lungs and less is swallowed or absorbed elsewhere:

• breathe out fully before each puff
• press and breathe in slowly and deeply (metered-dose inhalers), or quickly and deeply (dry-powder inhalers)
• hold your breath for up to 10 seconds
• use a spacer with metered-dose inhalers if advised
• rinse your mouth and spit afterwards

Ask your pharmacist or respiratory nurse to check your technique once a year — it's free and quick.

Frequently asked questions

Can Symbicort or Advair cause bruising?

These combination inhalers contain an inhaled steroid (budesonide or fluticasone). Like other inhaled steroids, they can contribute to easy bruising in some people, especially at higher doses over time.

Is bruising from inhalers dangerous?

Usually not. It reflects thinner skin rather than a bleeding problem. Bruising with other bleeding or without any knock should be checked.

Does a spacer reduce bruising from inhalers?

A spacer improves delivery to the lungs and reduces medicine left in the mouth and throat. It may modestly reduce how much is absorbed, but the main benefit is better treatment.

Will bruising stop if I lower my inhaler dose?

It may improve over time if your doctor can safely lower the dose. Never change it yourself.
