Which medication class is contraindicated in children with asthma?

Cough suppressants are generally contraindicated in children with asthma because they may inhibit the natural cough reflex, which is important for clearing mucus from the airways. Coughing can help prevent mucus build-up and facilitate better airflow, which is crucial in managing asthma. By suppressing the cough, these medications can potentially worsen respiratory distress and lead to complications in asthmatic children.

In contrast, bronchodilators are often used to relieve symptoms of asthma by relaxing the muscles around the airways, making it easier to breathe. Antihistamines are typically used to manage allergies and can sometimes help alleviate asthma exacerbations caused by allergic reactions. Corticosteroids are used to reduce inflammation in the airways and are essential in the long-term management of asthma, making them a critical part of asthma treatment regimens.
