Theophylline is no longer commonly used due to its narrow therapeutic index, which makes it difficult to manage safely, and its potential for significant side effects, including cardiac and central nervous system toxicity. Additionally, newer medications for asthma and chronic obstructive pulmonary disease (COPD) offer more effective and safer options, leading to a decline in theophylline's use.
