Interactions between your drugs

ritodrine doxepin topical

Applies to: ritodrine and doxepin topical

MONITOR: Concomitant use of beta-2 adrenergic agonists with tricyclic antidepressants (TCAs) may increase the risk and/or severity of cardiovascular adverse effects such as hypertension, palpitation, chest pain, and arrhythmia. In addition, both classes of drugs have been reported to produce electrocardiographic changes including flattening of the T wave and prolongation of the QTc interval, and these effects may be additive during coadministration.

MANAGEMENT: Caution is advised if beta-2 agonists are used with TCAs, or within two weeks of discontinuing the latter. Cardiovascular status should be closely monitored.

Drug and food interactions

Moderate

ritodrine food

Applies to: ritodrine

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
