This is a crucial sign that you need to talk to your doctor about adding or adjusting a&nbsp;long-term \u201ccontrol\u201d medication (like an inhaled steroid).&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Technique is Everything<\/strong><\/h3>\n\n\n\n<p>Shake the inhaler well before each puff. Exhale fully, inhale slowly and deeply as you press the canister, and then hold your breath for up to 10 seconds.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Wait One Minute<\/strong><\/h3>\n\n\n\n<p>If you need a second puff, wait at least one full minute before taking it.
