What Is the Combimist L Inhaler?
The Combimist L Inhaler is a metered‑dose device that delivers a precise amount of a long‑acting bronchodilator combined with an anti‑inflammatory steroid. It’s aimed at people with moderate to severe asthma or chronic obstructive pulmonary disease (COPD) who need consistent control of airway narrowing.
Unlike rescue inhalers that you pop in a pinch, Combimist L is designed for maintenance therapy. Each puff contains a fixed micro‑gram dose that your lungs absorb within seconds, allowing the airway muscles to relax and the inflammation to calm down over time.
Because the dose is built into the device, you don’t have to measure anything manually. The inhaler’s spring‑loaded mechanism ensures you get the same amount each time, which is crucial for keeping symptoms stable.
Regulatory bodies in Australia, the US and the EU have approved it after large‑scale PhaseIII trials showed a 30‑40% reduction in exacerbations compared with placebo. Those studies also confirmed that the safety profile matches other inhaled corticosteroid/long‑acting β‑agonist (ICS/LABA) combos on the market.

How to Use the Combimist L Inhaler Correctly
Getting the technique right can feel odd at first, but a few simple steps turn the device into a reliable daily ally. Follow this routine every time you take a puff:
- Prepare the inhaler: Shake it gently for about 5 seconds. This mixes the medication inside the canister.
- Exhale fully: Breathe out completely, but don’t exhale into the mouthpiece.
- Seal your lips: Place the mouthpiece between your teeth and close your lips tightly around it. No teeth should be biting the edge.
- Inhale slowly and deeply: Press down on the canister once while beginning a slow, steady breath in through the mouthpiece. Aim for a breath that lasts 3‑4 seconds.
- Hold your breath: After the inhalation, remove the device and hold your breath for about 10 seconds. This gives the medication time to settle on the airway walls.
- Exhale gently: Breathe out slowly through the nose, not the mouth.
- Repeat if prescribed: If your doctor advised two puffs, wait about 30 seconds and repeat steps 1‑6.
- Rinse your mouth: After the final puff, rinse with water and spit out. This reduces the risk of oral thrush, a common side effect of inhaled steroids.
Here are a few practical tips to avoid common pitfalls:
- Don’t shake too hard: Vigorous shaking can generate excess propellant, which might cause a louder spray and could affect dose consistency.
- Check the dose counter: Most Combimist L models have a built‑in counter that clicks down with each actuation. When it reaches “0”, the inhaler is empty and needs replacing.
- Avoid using a spacer: The design already incorporates a built‑in spacer; adding an external one can actually reduce drug delivery efficiency.
- Keep the device upright: Store it vertically to prevent the valve from sticking or leaking.

Safety, Side Effects, Storage & Frequently Asked Questions
Even though Combimist L is widely regarded as safe, it’s worth knowing the full picture before you make it part of your routine.
Common side effects
- Throat irritation or a dry feeling right after inhalation.
- Hoarseness or a slight change in voice.
- Occasional cough, especially if you forget to rinse your mouth.
- Rarely, oral thrush (a fungal infection) if proper oral hygiene isn’t followed.
Most of these symptoms fade after a week as your body gets used to the medication. If any effect persists or worsens, contact your healthcare provider.
Serious but uncommon reactions
- Sudden worsening of breathing (paradoxical bronchospasm).
- Allergic reactions - rash, swelling, or difficulty swallowing.
- Elevated heart rate or palpitations, particularly in patients sensitive to β‑agonists.
These require immediate medical attention.
Storage guidelines
- Keep the inhaler below 30°C (86°F); avoid leaving it in a hot car.
- Store in a dry place; humidity can affect the valve mechanism.
- Do not freeze the device - the propellant expands and could damage the canister.
- Keep it out of reach of children; the child‑proof cap should stay on when not in use.
Frequently asked questions
- Can I use Combimist L during a migraine? Yes, the inhaler won’t interfere with migraine medication. However, always double‑check with your doctor if you’re on MAO‑inhibitors.
- What should I do if I accidentally swallow a dose? It’s unlikely to cause harm, but call your poison control centre or GP for reassurance.
- Is it safe to travel internationally with this inhaler? Absolutely. Keep it in its original packaging with the prescription label visible. Some countries require a doctor’s note, so carry one just in case.
- Can I switch from a rescue inhaler to Combimist L? No. Combimist L is for maintenance only; you still need a fast‑acting rescue inhaler for sudden attacks.
- How often should I replace the inhaler? Most devices last 200‑250 doses. If you’re on a twice‑daily regimen, that’s roughly 4‑5 months. Replace as soon as the counter hits zero or the spray feels weak.
Troubleshooting common issues
- Weak spray or “click” without mist: The canister might be empty or the valve clogged. Warm the inhaler gently in your hands for 30 seconds and try again. If it still fails, replace the unit.
- Feeling dizzy after inhalation: That could be a sign of too high a dose of the bronchodilator component. Reduce the frequency only after consulting your doctor.
- Persistent cough: Verify you’re not inhaling too quickly. A rapid breath can cause medication to deposit in the throat rather than the lungs.
Remember, the best way to keep your symptoms under control is to pair the inhaler with a solid action plan: know your triggers, use a peak‑flow meter, and schedule regular reviews with your respiratory therapist.
If you’re just starting on Combimist L, give yourself a week to settle into the routine. Track how you feel each day - a simple notebook or a health app can highlight patterns you might otherwise miss.
Finally, don’t hesitate to reach out to your pharmacist for a quick “show‑me‑how” demo. A few minutes of live instruction can prevent a lot of frustration later on.
