Holding your breath for about 5 seconds after inhaling from an albuterol inhaler is crucial for ensuring that the medication reaches deep into the lungs where it can be most effective. This practice allows for better absorption of the medication into the airway tissues, maximizing its bronchodilator effects. The act of holding the breath prevents the medication from being immediately exhaled, increasing its therapeutic benefit.

Using an inhaler only during severe symptoms would not be effective since albuterol is often prescribed for prevention and control of symptoms, particularly for those with conditions like asthma. Administering the medication immediately before bedtime isn't generally recommended unless specifically advised by a healthcare provider, as it can lead to nighttime symptoms if the medication wears off. Using the inhaler every hour is inappropriate, as it may lead to overuse and potential side effects; albuterol is typically used on an as-needed basis or according to a prescribed schedule.
