Use caution in patients with cardiovascular disease (arrhythmia or hypertension or CHF), convulsive disorders, diabetes, glaucoma, hyperthyroidism, or hypokalemia. Beta agonists may cause elevation in blood pressure, heart rate, and result in CNS stimulation/excitation. Beta2 agonists may increase risk of arrhythmia, increase serum glucose, or decrease serum potassium.
Do not exceed recommended dose; serious adverse events including fatalities, have been associated with excessive use of inhaled sympathomimetics. Rarely, paradoxical bronchospasm may occur with use of inhaled bronchodilating agents; this should be distinguished from inadequate response. All patients should utilize a spacer device when using a metered-dose inhaler; in addition, face masks should be used in children <4 years of age.
Because of its minimal effect on beta1-receptors and its relatively long duration of action, albuterol is a rational choice in the elderly when an inhaled beta agonist is indicated. Oral use should be avoided in the elderly due to adverse effects. Patient response may vary between inhalers that contain chlorofluorocarbons and those which are chlorofluorocarbon-free.

Syrup: Store at 2°C to 30°C (36°F to 86°F)
Onset of action: Peak effect: Nebulization/oral inhalation: 0.5-2 hours; Oral: 2-3 hours
Duration: Nebulization/oral inhalation: 3-4 hours; Oral: 4-6 hours
Metabolism: Hepatic to an inactive sulfate
Half-life elimination: Inhalation: 3.8 hours; Oral: 3.7-5 hours
Excretion: Urine (30% as unchanged drug)
Oral:
Children: Bronchospasm (treatment):
2-6 years: 0.1-0.2 mg/kg/dose 3 times/day; maximum dose not to exceed 12 mg/day (divided doses)
6-12 years: 2 mg/dose 3-4 times/day; maximum dose not to exceed 24 mg/day (divided doses)
Extended release: 4 mg every 12 hours; maximum dose not to exceed 24 mg/day (divided doses)
Children >12 years and Adults: Bronchospasm (treatment): 2-4 mg/dose 3-4 times/day; maximum dose not to exceed 32 mg/day (divided doses)
Extended release: 8 mg every 12 hours; maximum dose not to exceed 32 mg/day (divided doses). A 4 mg dose every 12 hours may be sufficient in some patients, such as adults of low body weight.
Elderly: Bronchospasm (treatment): 2 mg 3-4 times/day; maximum: 8 mg 4 times/day
Inhalation: MDI 90 mcg/puff:
Children
12 years:
Bronchospasm (acute): 4-8 puffs every 20 minutes for 3 doses, then every 1-4 hours; spacer/holding-chamber device should be used
Exercise-induced bronchospasm (prophylaxis): 1-2 puffs 5 minutes prior to exercise
Children >12 years and Adults:
Bronchospasm (acute): 4-8 puffs every 20 minutes for up to 4 hours, then every 1-4 hours as needed
Exercise-induced bronchospasm (prophylaxis): 2 puffs 5-30 minutes prior to exercise
Children
4 years and Adults: Bronchospasm (chronic treatment): 1-2 inhalations every 4-6 hours; maximum: 12 inhalations/day
NIH guidelines: 2 puffs 3-4 times a day as needed; may double dose for mild exacerbations
Nebulization:
Children
12 years:
Bronchospasm (treatment): 0.05 mg/kg every 4-6 hours; minimum dose: 1.25 mg, maximum dose: 2.5 mg
2-12 years: AccuNeb™: 0.63 mg or 1.25 mg 3-4 times/day, as needed, delivered over 5-15 minutes
Children >40 kg, patients with more severe asthma, or children 11-12 years: May respond better with a 1.25 mg dose
Bronchospasm (acute): Solution 0.5%: 0.15 mg/kg (minimum dose: 2.5 mg) every 20 minutes for 3 doses, then 0.15-0.3 mg/kg (up to 10 mg) every 1-4 hours as needed; may also use 0.5 mg/kg/hour by continuous infusion. Continuous nebulized albuterol at 0.3 mg/kg/hour has been used safely in the treatment of severe status asthmaticus in children; continuous nebulized doses of 3 mg/kg/hour ± 2.2 mg/kg/hour in children whose mean age was 20.7 months resulted in no cardiac toxicity; the optimal dosage for continuous nebulization remains to be determined.
Note: Use of the 0.5% solution should be used for bronchospasm (acute or treatment) in children <15 kg. AccuNeb™ has not been studied for the treatment of acute bronchospasm; use of the 0.5% concentrated solution may be more appropriate.
Children >12 years and Adults:
Bronchospasm (treatment): 2.5 mg, diluted to a total of 3 mL, 3-4 times/day over 5-15 minutes
NIH guidelines: 1.25-5 mg every 4-8 hours
Bronchospasm (acute) in intensive care patients: 2.5-5 mg every 20 minutes for 3 doses, then 2.5-10 mg every 1-4 hours as needed, or 10-15 mg/hour continuously
Hemodialysis: Not removed
Peritoneal dialysis: Significant drug removal is unlikely based on physiochemical characteristics
Inhalation: MDI: Shake well before use; prime prior to first use, and whenever inhaler has not been used for >2 weeks, by releasing 4 test sprays into the air (away from face)
Oral: Do not crush or chew extended release tablets.
Self-administered inhalation: Do not freeze. Shake canister before using. Sit when using medication. Close eyes when administering albuterol to avoid spray getting into eyes. Exhale slowly and completely through nose; inhale deeply through mouth while administering aerosol. Hold breath for 5-10 seconds after inhalation. Wait at least 1 full minute between inhalations. Wash mouthpiece between use. If more than one inhalation medication is used, use albuterol first and wait 5 minutes between medications. Prime inhaler prior to first use, and whenever the inhaler has not been used for more than 2 weeks, by releasing 4 test sprays into the air (away from face). Discard inhaler after labeled number of doses are used, even if the canister does not feel empty. Ventolin® HFA: Discard canister after 200 actuations or 3 months after removal from foil pouch, whichever comes first. Store with mouthpiece down. Do not allow metal canister to become wet.
Self-administered nebulizer: Wash hands before and after treatment. Wash and dry nebulizer after each treatment. Twist open the top of one unit dose vial and squeeze contents into nebulizer reservoir. Connect nebulizer reservoir to the mouthpiece or face mask. Connect nebulizer to compressor. Sit in comfortable, upright position. Place mouthpiece in your mouth or put on face mask and turn on compressor. If face mask is used, avoid leakage around the mask to avoid mist getting into eyes which may cause vision problems. Breathe calmly and deeply until no more mist is formed in nebulizer (about 5 minutes). At this point treatment is finished.
Volmax®: Tablets should be swallowed whole; do not crush or chew. Outer coating of tablet is not absorbed and may be found eliminated in stool.
Wait at least 1 minute between first and second puff of MDI. Because of its minimal effect on beta1 receptors and its relatively long duration of action, albuterol is a rational choice in the elderly when a beta agonist is indicated. All patients should utilize a spacer device when using a metered-dose inhaler.
