Drug Interactions between Qulipta and Zyrtec

Alcohol can increase the nervous system side effects of cetirizine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with cetirizine. Do not use more than the recommended dose of cetirizine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

MONITOR: Coadministration with grapefruit products or green tea, inhibitors of CYP450 3A4, may increase the plasma concentrations of atogepant, which is primarily metabolized by the isoenzyme. When atogepant was administered with the potent CYP450 3A4 inhibitor itraconazole in healthy study subjects, atogepant peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 2.2- and 5.5-fold, respectively. However, moderate and weak inhibitors may interact to a much lesser extent. Population pharmacokinetic modeling has suggested that moderate (e.g., cyclosporine, ciprofloxacin, fluconazole, fluvoxamine, grapefruit juice) or weak (e.g., cimetidine, esomeprazole) CYP450 3A4 inhibitors may increase atogepant AUC by 1.7- and 1.1-fold, respectively. The changes in atogepant exposure when coadministered with moderate or weak CYP450 3A4 inhibitors are not expected to be clinically significant.

MANAGEMENT: Caution is advised for patients taking atogepant and consuming grapefruit products, large amounts of green tea beverages or green tea extract. Patients should be monitored for nausea, constipation, and fatigue.
