What should be avoided immediately after using an inhaler?

Avoiding consumption of food or drink immediately after using an inhaler is important primarily because it can ensure that the medication delivered through the inhaler is not washed away or diluted by anything consumed right afterward. This is particularly relevant when using a corticosteroid inhaler, as these medications are designed to coat the airways for effectiveness. Drinking or eating may interfere with the absorption or efficacy of the medication.

Engaging in physical activity, doing mouth exercises, or using a nebulizer may not have the same direct impact on how well the inhaler works. Physical activity may be advisable post-inhalation, especially if the inhaler is used as a bronchodilator prior to exercise. Mouth exercises don't typically interfere with the medication, and nebulizers serve a different purpose and are used at different times than inhalers. Therefore, waiting to consume food or drink allows for optimal absorption and effectiveness of the medication administered via the inhaler.
