Common side effects of bronchodilators (including products like Broncol) include trembling, nervousness, heart palpitations and muscle cramps[1]. Some people may also experience rapid heartbeat, anxiety, headache, throat irritation, nausea, and vomiting[1]. Other reported effects are shakiness in the hands or feet, and less commonly, chest tightness or paradoxical bronchospasm (worsening of breathing or wheezing)[2][4].
Albuterol, a commonly used bronchodilator, may cause tremor, nausea, rapid heart rate, palpitations, and nervousness[3]. Other bronchodilators like levalbuterol hydrochloride have reported side effects including bronchitis, dizziness, pain, and vomiting[3].
Less frequent but serious reactions can include allergic reactions (rash, facial swelling, difficulty breathing), paradoxical bronchospasm (opposite to the intended effect), and serious cardiovascular events like arrhythmias or cardiomyopathy[1][5][8]. Theophylline, used less often due to its side effect profile, can cause rash, fainting, seizures, and unusual heart rhythms[1][7].
Anticholinergic bronchodilators (another class) may cause dry mouth, blurred vision, urinary retention, and, in rare cases, acute delirium, particularly in older adults[6][8].
Other possible adverse effects include:
- Dizziness
- Muscle pain or cramps
- Restlessness or hyperactivity
- Digestive upset (diarrhea, stomachache)
- Hallucinations (rare)
Always report persistent or severe side effects to a healthcare provider, as dose adjustment or alternative therapy may be required.
