Drug Interactions between sertraline and Wegovy

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of sertraline. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills. In addition, limited clinical data suggest that consumption of grapefruit juice during treatment with sertraline may result in increased plasma concentrations of sertraline. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism by certain compounds present in grapefruit. An in-vitro study demonstrated that grapefruit juice dose-dependently inhibits the conversion of sertraline to its metabolite, desmethylsertraline. In a study with eight Japanese subjects, mean plasma levels of sertraline increased by approximately 100% and maximum plasma concentrations increased by 66% after the ingestion of three 250 mL glasses of grapefruit juice per day for 5 days and administration of a single dose of sertraline 75 mg on the sixth day. In another small study with 5 patients, mean sertraline trough levels increased by 47% after taking sertraline for at least 6 weeks, then taking sertraline with 240 mL grapefruit juice daily for 1 week. The clinical significance is unknown; however, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability. The possibility of significant interaction in some patients should be considered.

MANAGEMENT: Patients receiving sertraline should be advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how sertraline affects them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities. Some authorities recommend that consumption of grapefruit juice should be avoided during sertraline therapy.

ADJUST DOSING INTERVAL: Taking oral semaglutide with food, beverage, or other oral medications may alter semaglutide absorption and exposure. In a controlled study with healthy volunteers, limited or no measurable semaglutide exposure was observed in subjects that were fed 30 minutes prior to taking oral semaglutide, while all subjects that fasted overnight and 30 minutes after the oral semaglutide dose had measurable semaglutide exposure. Area under the curve (AUC) and semaglutide peak plasma concentration (Cmax) were approximately 40% greater in subjects that fasted compared to those who did not. AUC and Cmax were also increased with a post-dose fasting period greater than 30 minutes.

MANAGEMENT: It is recommended that oral semaglutide be taken 30 minutes before the first food, beverage, or other oral medications of the day with no more than 4 ounces of plain water to ensure its efficacy. Fasting longer than 30 minutes after the oral semaglutide dose may lead to increased gastrointestinal side effects including nausea, vomiting, or diarrhea.
