An inhaler delivers medication directly into the lungs to manage respiratory conditions. Proper use, including the timing between puffs, is important for the medication’s effectiveness.
Types of Inhalers and Their Use
Inhalers fall into two main categories: quick-relief (rescue) and long-term control (maintenance). Rescue inhalers provide rapid symptom relief by quickly opening airways, used as needed for flare-ups or before exercise. Maintenance inhalers are taken regularly, usually daily, to prevent symptoms and reduce airway inflammation.
Inhalers also come as metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). MDIs deliver medication as a fine mist, often requiring coordination. DPIs deliver medication as a dry powder, activated by a quick, deep inhalation. Technique and timing recommendations vary by inhaler type.
Specific Waiting Times Between Puffs
When taking multiple puffs from the same metered-dose inhaler, a waiting period is recommended. For most MDIs, especially quick-relief medications like albuterol, wait 30 to 60 seconds between puffs. This pause allows the first dose to begin opening airways and the inhaler to reset for the next puff.
If using different inhalers sequentially, such as a rescue followed by a maintenance inhaler, the waiting time is longer. Use the quick-relief inhaler first, wait 5 to 10 minutes, then take the maintenance inhaler. This sequence allows the rescue medication to open airways, making the maintenance medication more effective. Always follow specific instructions from your healthcare provider or medication packaging, as timings can vary based on the specific drug and device.
Why Proper Timing Matters
Proper timing between inhaler puffs is important for both medication effectiveness and to reduce side effects. When using an MDI, waiting between puffs allows the medication and its propellant to remix inside the canister. This ensures the second puff delivers the correct dose. Failing to wait can result in an incomplete or less effective dose.
The initial puff of a bronchodilator can start to widen the constricted airways in the lungs. This widening creates a more open pathway, allowing the second puff to penetrate more deeply into the lungs. By reaching the smaller airways, the medication can work more efficiently, leading to better symptom control and optimal drug absorption. Proper timing also helps prevent a high concentration of medication from settling in the mouth or throat, which can reduce local side effects.
Ensuring Correct Inhaler Technique
Correct inhaler technique for each puff is important for the medication to reach the lungs effectively. Before each use, shake metered-dose inhalers to ensure the medication and propellant are well mixed. For both MDIs and DPIs, exhaling completely before inhaling the medication creates space in the lungs for the medicine.
A tight seal around the mouthpiece is also necessary to prevent medication from escaping. After inhaling, holding your breath for about 5 to 10 seconds allows the medication particles to settle in the lungs. Using a spacer device with metered-dose inhalers can also improve medication delivery, especially for those who find coordinating breath and activation difficult, helping more medicine reach the lungs and less settle in the mouth.
