What is theophylline?

Donna Hill Howes, RN
Family Practitioner

Sustained-release theophylline (Theo-24, Theochron, Uniphyl) helps to open airways and reduce inflammation in the lungs in people with COPD or asthma. It can also improve your response to corticosteroid drugs.

It is not the first drug a doctor would prescribe for the treatment of chronic obstructive pulmonary disease (COPD), because it is less effective and has more side effects than newer medications. Theophylline is usually only added when inhaled bronchodilators or corticosteroids aren't controlling your symptoms.

Theophylline is sometimes prescribed, in combination with an inhaled corticosteroid, when asthma is not well controlled with an inhaled corticosteroid and a leukotriene modifier. This combination may be appropriate for people with a poor response to a long-acting beta-agonist, a strong preference for oral therapy, or a concern about cost.  However, it should be used only by adults and children of ages 5 or older.
