Do pediatric bronchodilators have side effects?

Bronchodilators are actually an antiasthmatic drug that can relieve bronchospasm in patients. Generally speaking, some asthma patients often need to use bronchodilators during acute attacks. Bronchodilators generally do not have anti-inflammatory effects. When an asthma attack occurs, this bronchodilator works very quickly, but it may lead to drug dependence.

Bronchodilators that act on the sympathetic nerves can have some side effects of psychostimulation. If you experience other obvious symptoms after taking the medicine, such as nervousness, insomnia, trembling hands and feet, pale face, etc., you can try changing the medicine or adjusting the dosage. Severe overdose reactions include severe vomiting and convulsions, and the drug should be discontinued at this time. If you use an inhaled bronchodilator, side effects are rare because the concentration of the drug entering the blood is very low.

There are three main types of commonly used bronchodilators: anticholinesterase drugs, β2 receptor agonists, and methylxanthines. The first two can be taken by inhalation, and inhalation is currently recommended because it takes effect quickly and has few systemic adverse reactions. Inhalation devices include metered dose inhalers (MDI) and nebulizer inhalation devices. In order to improve the inhalation effect, a mist storage device can be added between the MDI and the oral cavity. In addition, there are dry powder inhalers (disc inhalers) and inhalation-triggered metered-dose inhalation devices (Dubao series), which are easier to master and have better inhalation effects. The key to inhalation therapy is that the patient must master the inhalation technique.

It should also be noted that although the more common bronchodilators have no side effects or have relatively few side effects, there is a type of bronchodilator that may cause some serious side effects, and that is theophylline. Bronchodilators containing theophylline may easily cause nausea and vomiting, abdominal discomfort, or tachycardia.
