Edit list (add/remove drugs)

Interactions between your drugs

Moderate

fexofenadine resmetirom

Applies to: Allegra-D 24 Hour Allergy & Congestion (fexofenadine / pseudoephedrine) and resmetirom

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with resmetirom may increase the plasma concentrations and effects of drugs that are substrates of hepatic uptake transporters organic anion transporting polypeptides (OATP) 1B1, OATP 1B3, and/or the intestinal and hepatobiliary efflux transporter breast cancer resistance protein (BCRP). Resmetirom is both a substrate and an inhibitor of these transporters. Clinical studies exist for resmetirom with OATP1B1 and OATP1B3 substrates, simvastatin, and pravastatin; as well as with rosuvastatin and atorvastatin which are BCRP, OATP1B1 and OATP1B3 substrates. Resmetirom was shown to increase the systemic exposure (AUC) of simvastatin, pravastatin, rosuvastatin, and atorvastatin by 1.7-fold, 1.4-fold, 1.8-fold, and 1.4-fold, respectively. Clinical data are not available for other OATP 1B1, OATP 1B3 and/or BCRP substrates.

MANAGEMENT: Caution and closer monitoring may be advised if resmetirom is coadministered with drugs that are substrates of the OATP 1B1, OATP 1B3, and/or BCRP transporters. Dosage adjustments as well as clinical and laboratory monitoring for the development of adverse effects may be appropriate for some drugs whenever resmetirom is added to or withdrawn from therapy. Individual product labeling should be consulted for further guidance.

Drug and food interactions

Moderate

fexofenadine food

Applies to: Allegra-D 24 Hour Allergy & Congestion (fexofenadine / pseudoephedrine)

Consuming large amounts of certain fruit juices, including grapefruit, orange and apple, may decrease the levels of fexofenadine in your body. Fexofenadine should be taken with water and refrain from drinking large amounts of grapefruit, orange, or apple juice. This will make it easier for your body to absorb the medication.

Moderate

pseudoephedrine food

Applies to: Allegra-D 24 Hour Allergy & Congestion (fexofenadine / pseudoephedrine)

Consumer information for this interaction is not currently available.

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.
