Understanding Your Asthma Inhaler: Rescue vs. Maintenance

If you or someone you care for has asthma or COPD, you've probably been handed more than one inhaler at the pharmacy. It can be confusing — they look similar, but they work very differently. Using the wrong one at the wrong time can leave you undertreated or cause unnecessary side effects.

The Two Main Types

Rescue inhalers (also called short-acting bronchodilators) work fast — usually within minutes. They relax the muscles around your airways to open them up quickly. Albuterol (ProAir, Ventolin, Proventil) is the most common. You use these when you feel symptoms coming on: tightness, wheezing, shortness of breath.

Maintenance inhalers are taken every day, whether you feel symptoms or not. They work slowly to reduce inflammation and keep airways open over time. Examples include:

• Inhaled corticosteroids (ICS) like fluticasone (Flovent)
• Long-acting bronchodilators (LABA) like salmeterol
• Combination inhalers like Advair (fluticasone + salmeterol) or Symbicort

A Common Mistake

Many patients use their rescue inhaler daily and skip their maintenance inhaler because "it doesn't feel like it does anything." This is backwards. The maintenance inhaler is preventing the attacks — you don't feel it working because it's keeping you stable. The rescue inhaler is for emergencies, not daily use.

If you're using your rescue inhaler more than twice a week, that's a sign your asthma isn't well-controlled and you should talk to your doctor.

Checking Availability

Albuterol inhalers have been subject to periodic shortages. Before heading to the pharmacy, use MedTrack to check which locations near you have your specific inhaler in stock. This is especially important if you're running low — don't wait until you're out.

Inhaler Technique Matters

Even the best inhaler won't work if you're not using it correctly. Key tips:

• Shake the inhaler before each use (for MDIs)
• Breathe out fully before inhaling
• Inhale slowly and deeply
• Hold your breath for 10 seconds after inhaling
• Use a spacer if recommended by your doctor

Ask your pharmacist to watch your technique — they can spot problems you might not notice.
