Dosage Adjustment Pediatric Patients 6 to 12 Years of Age Who Fail to Respond to the Initial Starting Dosage of 2 mg Four Times a Day : For pediatric patients from 6 to 12 years of age who fail to respond to the initial starting dosage of 2 mg four times a day, the dosage may be cautiously increased stepwise, but not to exceed 24 mg/day (given in divided doses).
Adults and Pediatric Patients Over 12 Years of Age:
For adults and pediatric patients over 12 years of age, a dosage above 4 mg four times a day should be used only when the patient fails to respond to lower dose. The dosage should be cautiously increased stepwise up to a maximum of 8 mg four times a day as tolerated if a favorable response does not occur with the 4 mg initial dosage.
Elderly Patients and Those Sensitive to Beta-adrenergic Stimulators :
An initial dosage of 2 mg three or four times a day is recommended for elderly patients and for those with a history of unusual sensitivity to beta-adrenergic stimulators. If adequate bronchodilation is not obtained, dosage may be increased gradually as tolerated to as much as 8 mg three or four times a day.
The total daily dose should not exceed 24 mg per day in pediatric patients from 6 to 12 years of age and 32 mg in adults and pediatric patients over 12 years of age.
ADVERSE REACTIONS
The adverse reactions to albuterol are similar in nature to those of other sympathomimetic agents.

Although not reported for albuterol extended-release tablets in the above study, there have been reports of tremor in other trials. When all clinical experience is considered, the incidence of tremor is approximately the same as that seen with albuterol tablets.
A placebo-controlled trial of 4 weeks duration in 157 mild-to-moderate asthmatic children aged 6 to 12 years, demonstrated the safety of escalating doses of albuterol extended-release tablets. In this study, the starting dose of albuterol extended-release tablets was 4 mg twice daily.
Patients were advanced to a maximum of 12 mg albuterol extended-release tablets twice daily by the investigator, based on patient tolerance and response. Only one of the 79 children treated with albuterol extended-release tablets was advanced to the maximum daily dose of 12 mg twice daily.
WARNINGS
Paradoxical Bronchospasm Albuterol tablets can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs, albuterol tablets should be discontinued immediately and alternative therapy instituted.
Deterioration of Asthma Asthma may deteriorate acutely over a period of hours, or chronically over several days or longer. , corticosteroids. Use of Anti-Inflammatory Agents The use of beta-adrenergic agonist bronchodilators alone may not be adequate to control asthma in many patients.
, corticosteroids. Cardiovascular Effects Albuterol tablets, like all other beta-adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms.
Although such effects are uncommon after administration of albuterol tablets at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression.
The clinical significance of these findings is unknown. Therefore, albuterol tablets, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.
Immediate Hypersensitivity Reactions Immediate hypersensitivity reactions may occur after administration of albuterol, as demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm, anaphylaxis and oropharyngeal edema.
Rarely, erythema multiforme and Stevens-Johnson syndrome have been associated with the administration of oral albuterol sulfate in children.
CONTRAINDICATIONS
Albuterol tablets are contraindicated in patients with a history of hypersensitivity to albuterol, or any of their components.

The following treatment-related adverse events occurred in more than 5% of treated patients and were greater in albuterol extended-release tablets patients when compared to placebo: Incidence of Adverse Events (% of Patients) in a 4-Week Placebo-Controlled Trial in 157 Children 6 to 12 Years of Age Adverse Event Albuterol Extended-release Tablets % Placebo % Headache 22 9 Nervousness 13 6 Insomnia 11 5 Tremor 10 1 Palpitation 8 1 Tachycardia 8 1 Other adverse events were noted in 5% or fewer patients, or had equal or greater rates of occurrence in placebo patients than in albuterol extended-release tablets patients.
Cases of urticaria, angioedema, rash, bronchospasm, oropharyngeal edema and arrhytmias (including atrial fibrillation, supraventricular tachycardia, and extrasystoles) have been reported after the use of albuterol tablets. In addition to those adverse reactions reported above, albuterol, like other sympathomimetic agents, can cause adverse reactions such as angina, central nervous system stimulation, drying or irritation of the oropharynx, hypertension, unusual taste, and vertigo.
The reactions are generally transient in nature, and it is usually not necessary to discontinue treatment with albuterol tablets. In selected cases, however, dosage may be reduced temporarily; after the reaction has subsided, dosage should be increased in small increments to the optimal dosage.
