EryPed and Lotronex

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using erythromycin together with alosetron can increase the blood levels or add to the side effects of alosetron. Contact your doctor if you experience constipation or signs and symptoms of ischemic colitis such as rectal bleeding, bloody diarrhea, and new or worsening abdominal pain. If your doctor does prescribe these medications together, you may need a dose adjustment or special tests to safely take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with potent inhibitors of CYP450 3A4 may increase the plasma concentrations of alosetron, which has been shown in vitro to be partially metabolized by the isoenzyme. In 38 healthy female subjects, pretreatment with ketoconazole (200 mg twice a day for 7 days) increased the area under the plasma concentration-time curve (AUC) of alosetron (1 mg single oral dose) by 29% compared to administration of alosetron alone. Concomitant administration of alosetron with other CYP450 3A4 inhibitors has not been evaluated.

MANAGEMENT: Because alosetron is associated with potentially serious and life-threatening, dose-related gastrointestinal adverse effects, caution is advised during concomitant use with potent CYP450 3A4 inhibitors such as itraconazole, ketoconazole, voriconazole, nefazodone, delavirdine, protease inhibitors, and ketolide and certain macrolide antibiotics. Patients should be advised to immediately discontinue alosetron and notify their physician if they experience constipation or signs and symptoms of ischemic colitis such as rectal bleeding, bloody diarrhea, and new or worsening abdominal pain. Alosetron should not be resumed if ischemic colitis is diagnosed. Ischemic colitis and other serious complications such as obstruction, perforation, impaction, and toxic megacolon have resulted in hospitalization, blood transfusion, surgery, and death.
