Theophylline is a prescription medicine that is used for the treatment of airway spasms caused by asthma or chronic obstructive pulmonary disease (COPD). It is available in several different forms, including capsules, tablets, an elixir, and an injection. Theophylline works by causing muscles around the airways to relax, which helps to improve breathing. Side effects of the medication can include headaches, vomiting, insomnia, and nausea.
What Is Theophylline?
Theophylline is a prescription medication used to treat airway spasms (called bronchospasms). Bronchospasms are most common in people with asthma but can also occur in people with chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema.
