From the Terbutaline (Terbutaline Sulfate) label · effective 2019-11-15
Drug Interactions The concomitant use of terbutaline sulfate tablets with other sympathomimetic agents is not recommended, since the combined effect on the cardiovascular system may be deleterious to the patient.
If the patient needs more doses of terbutaline sulfate tablets than usual, this may be a marker of destabilization of asthma and requires reevaluation of the patient and the treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids.
Early consideration should be given to adding anti-inflammatory agents, e.g., corticosteroids.
Cardiovascular Effects Terbutaline sulfate, like all other beta-adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms.
