Proair Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Proair (albuterol sulfate) is used to prevent and treat wheezing and shortness of breath caused by breathing problems such as asthma and chronic obstructive pulmonary disease. It is also used to prevent exercise-induced asthma. Proair belongs to a class of drugs known as bronchodilators that relaxes muscles in the airways and increases air flow to the lungs. Common side effects include nervousness, shaking (tremor), headache, mouth/throat dryness or irritation, cough, nausea or dizziness.
Proair is inhaled by mouth as directed by a doctor, usually every 4 to 6 hours as needed. Dosage is based on your medical condition and response to treatment. Proair may adversely interact with other medications including diuretics (water pills), digoxin, beta-blockers, antidepressants, MAO inhibitors, and other bronchodilators. Tell your doctor all medications you are taking. This medication should be used only when clearly needed during pregnancy. Tell your doctor if you are pregnant. It is unknown if this medication passes into breast milk. Consult your doctor before breast-feeding.

Proair FDA Prescribing Information: Side Effects
Use of PROAIR HFA (albuterol sulfate inhalation aerosol) may be associated with the following:
- Paradoxical bronchospasm [see WARNINGS AND PRECAUTIONS]
- Cardiovascular Effects [see WARNINGS AND PRECAUTIONS]
- Immediate hypersensitivity reactions [see WARNINGS AND PRECAUTIONS]
- Hypokalemia [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
A total of 1090 subjects were treated with PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol, or with the same formulation of albuterol as in PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol, during the worldwide clinical development program.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adult and Adolescents 12 Years of Age and Older
The adverse reaction information presented in the table below concerning PROAIR HFA Inhalation Aerosol is derived from a 6-week, blinded study which compared PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol (180 mcg four times daily) with a double-blinded matched placebo HFA-Inhalation Aerosol and an evaluator-blinded marketed active comparator HFA-134a albuterol inhaler in 172 asthmatic patients 12 to 76 years of age. The table lists the incidence of all adverse events (whether considered by the investigator drug related or unrelated to drug) from this study which occurred at a rate of 3% or greater in the PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol treatment group and more frequently in the PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol treatment group than in the matched placebo group. Overall, the incidence and nature of the adverse events reported for PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol and the marketed active comparator HFA-134a albuterol inhaler were comparable.
Adverse Experience Incidences (% of Patients) in a Six-Week
|Body System/Adverse event (as Preferred Term)
||PROAIR HFA Inhalation Aerosol
(N = 58)
HFA-134a albuterol inhaler
(N = 56)
HFA-134a Inhalation Aerosol
(N = 58)
|Body as a Whole||Headache||7||5||2|
|* This table includes all adverse events (whether considered by the investigator drug related or unrelated to drug) which occurred at an incidence rate of at least 3.0% in the PROAIR HFA Inhalation Aerosol group and more frequently in the PROAIR HFA Inhalation Aerosol group than in the placebo HFA Inhalation Aerosol group.|
Adverse events reported by less than 3% of the patients receiving PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol but by a greater proportion of PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol patients than the matched placebo patients, which have the potential to be related to PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation
In small cumulative dose studies, tremor, nervousness, and headache were the most frequently occurring adverse events.
Pediatric Patients 4 to 11 Years of Age
Adverse events reported in a 3-week pediatric clinical trial comparing the same formulation of albuterol as in PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol (180 mcg albuterol four times daily) to a matching placebo HFA inhalation aerosol occurred at a low incidence rate (no greater than 2% in the active treatment group) and were similar to those seen in adult and adolescent trials.
The following adverse reactions have been identified during postapproval use of PROAIR HFA (albuterol sulfate inhalation aerosol) . Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Reports have included rare cases of aggravated bronchospasm, lack of efficacy, asthma exacerbation (reported fatal in one case), muscle cramps, and various oropharyngeal side-effects such as throat irritation, altered taste, glossitis, tongue ulceration, and gagging.
The following adverse events have been observed in postapproval use of inhaled albuterol: urticaria, angioedema, rash, bronchospasm, hoarseness, oropharyngeal edema, and arrhythmias (including atrial fibrillation, supraventricular tachycardia, extrasystoles). In addition, albuterol, like other sympathomimetic agents, can cause adverse reactions such as: angina, hypertension or hypotension, palpitations, central nervous system stimulation, insomnia, headache, nervousness, tremor, muscle cramps, drying or irritation of the oropharynx, hypokalemia, hyperglycemia, and metabolic acidosis.
