If you use an inhaler for asthma or COPD, getting the dose right can feel like a guessing game. Too little won’t control symptoms, too much may cause side effects. The good news is there are clear steps you can follow to land on the sweet spot.
Inhaled corticosteroids (ICS) come in low, medium and high strength. Your doctor will start you on a dose that matches how often you need relief and how severe your symptoms are. For most adults with mild asthma, a low‑dose inhaler taken once or twice daily is enough. If you have moderate disease, the medium dose usually does the trick, while severe cases may need high strength.
Every brand has its own micrograms per puff, so check the label. A “low” fluticasone might be 100 µg per actuation, whereas a “high” budesonide could be 800 µg. Don’t compare numbers across different drugs without a conversion chart – the potency varies.
When you feel your symptoms getting better, resist the urge to cut back on your own. Instead, set a follow‑up appointment after 4–6 weeks. Your doctor can look at your symptom diary and decide if a step‑down is safe.
If you keep having night waking or need rescue inhalers more than twice a week, that’s a sign the dose may be too low. Ask for an increase rather than adding another medication first.
Side effects like hoarseness or oral thrush are common if the inhaler isn’t rinsed properly. After each use, spit out the water and rinse your mouth – it cuts down on problems without changing the dose.
For kids, dosing is weight‑based. A child under 20 kg might need a quarter of an adult’s low dose, while older teens often follow adult guidelines. Always double‑check pediatric charts before making changes.
Sometimes doctors switch you to a combination inhaler that adds a long‑acting bronchodilator (LABA). The ICS part stays the same; the LABA helps open airways faster. If you’re moving to a combo, keep an eye on how often you need your rescue inhaler – it should drop.
Remember: never share your inhaler and don’t use someone else’s dose. Each person’s airway size and disease pattern are different.
In short, start with the doctor‑recommended strength, track symptoms daily, rinse after each puff, and schedule a check‑in to fine‑tune the amount. With these steps you’ll keep your lungs happy without extra side effects.
