摘要
Carvedilol is a nonselective beta-blocker and can cause bronchospasm that opposes theophylline's effect. It may also reduce theophylline clearance, raising levels and risk of toxicity.
用白話說明這項交互作用的意義
Carvedilol and Theophylline can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
