Drug Interaction Report

Using carvedilol together with racepinephrine may reduce the benefits of both medications, since they have opposing effects in the body. In addition, carvedilol can sometimes cause narrowing of the airways, which may worsen your breathing problems or trigger severe asthmatic attacks. Carvedilol is normally not recommended if you have asthma, a history of asthma, or severe chronic obstructive pulmonary disease (COPD). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact or are less likely to interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
