OverviewDosageSide EffectsInteractionsHalf-Life

Below are the general guidelines for dosing albuterol. Note that these dosages may be adjusted on a case-by-case basis for individual patients. Always follow your prescribing physician’s instructions for taking albuterol.

The following information comes from DailyMed, an FDA label information provider.

What if I miss a dose of albuterol?

According to Mayo Clinic, if you miss a dose of albuterol, take it immediately, unless you are closer to your next dosing time. If the latter is true, skip the missed dose and wait until the next one. Never double dose. Always take this medication as prescribed. Generally this medication is an as needed medication, and not required to be on a set schedule.

What if I overdose on albuterol?

The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of symptoms such as seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmias, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, and exaggeration of the pharmacological effects listed in ADVERSE REACTIONS. Hypokalemia may also occur. As with all sympathomimetic aerosol medications, cardiac arrest and even death may be associated with abuse of albuterol sulfate inhalation solution. Treatment consists of discontinuation of albuterol sulfate inhalation solution together with appropriate symptomatic therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of albuterol sulfate inhalation solution.

The oral median lethal dose of albuterol sulfate in mice is greater than 2000 mg/kg (approximately 580 times the maximum recommended daily inhalation dose of albuterol sulfate inhalation solution on a mg/m2 basis). The subcutaneous median lethal dose of albuterol sulfate in mature rats and small young rats is approximately 450 mg/kg and 2000 mg/kg, respectively (approximately 260 and 1200 times the maximum recommended daily inhalation dose of albuterol sulfate inhalation solution on a mg/m2 basis). The inhalation median lethal dose has not been determined in animals.

Dosage and Administration

The usual starting dosage for patients 2 to 12 years of age is 1.25 mg or 0.63 mg of albuterol sulfate inhalation solution administered 3 or 4 times daily, as needed, by nebulization. More frequent administration is not recommended.

To administer 1.25 mg or 0.63 mg of albuterol, use the entire contents of one unit-dose vial (3 mL of 1.25 mg or 0.63 mg inhalation solution) by nebulization. Adjust nebulizer flow rate to deliver albuterol sulfate inhalation solution over 5 to 15 minutes.

The use of albuterol sulfate inhalation solution can be continued as medically indicated to control recurring bouts of bronchospasm. During this time most patients gain optimum benefit from regular use of the inhalation solution.

Patients 6 to 12 years of age with more severe asthma (baseline FEV1 less than 60% predicted), weight > 40 kg, or patients 11 to 12 years of age may achieve a better initial response with the 1.25 mg dose.

For patients older than 12 years or older follow your physicians instructions, but similar dosages to pediatric patients may be suitable for adults aswell.

Albuterol sulfate inhalation solution has not been studied in the setting of acute attacks of bronchospasm. A 2.5 mg dose of albuterol provided by a higher concentration product (2.5 mg albuterol per 3 mL) may be more appropriate for treating acute exacerbations, particularly in children 6 years old and above.

If a previously effective dosage regimen fails to provide the usual relief, medical advice should be sought immediately, as this is often a sign of seriously worsening asthma which would require reassessment of therapy.

The drug compatibility (physical and chemical), clinical efficacy and safety of albuterol sulfate inhalation solution, when mixed with other drugs in a nebulizer have not been established.

The safety and efficacy of albuterol sulfate inhalation solution has been established in clinical trials when administered using the Pari LC Plus™ nebulizer and Pari PRONEB™ compressor. The safety and efficacy of albuterol sulfate inhalation solution when administered with other nebulizer systems have not been established.

Albuterol sulfate inhalation solution should be administered via jet nebulizer connected to an air compressor with adequate air flow, equipped with a mouthpiece or suitable face mask.
