Asthma medications: Know your options

Theophylline

You take this bronchodilator daily in pill form to treat mild asthma. Theophylline (Theo-24) relaxes the airways and decreases the lungs' response to irritants. Although theophylline isn't used much anymore, it can be helpful for nighttime asthma symptoms. You might need regular blood tests to make sure you're getting the correct dose.
