Ponstel and Zevalin In-111

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 ibritumomab tiuxetan together with mefenamic acid may increase the risk of bleeding. In clinical studies, treatment with ibritumomab tiuxetan alone has been associated with severe and sometimes fatal hemorrhage. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should seek immediate medical attention if you experience any unusual bleeding or bruising, or have other signs and symptoms of bleeding such as dizziness; lightheadedness; red or black, tarry stools; coughing up or vomiting fresh or dried blood that looks like coffee grounds; severe headache; and weakness. 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 CLOSELY: Coadministration of ibritumomab and drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Ibritumomab commonly causes severe and prolonged thrombocytopenia, and the risk is increased further in patients with mild thrombocytopenia at the initiation of therapy. Hemorrhage, including fatal cerebral hemorrhage, has occurred in a minority of patients in clinical studies. The median time to thrombocyte nadir was 7 to 9 weeks, and the median duration of thrombocytopenia was 22 to 35 days. However, in less than 5% of the cases, patients experienced severe cytopenia that extended beyond 12 weeks following administration of the ibritumomab therapeutic regimen. Platelet transfusions were given to 22% of patients in clinical trials.

MANAGEMENT: Caution is advised if ibritumomab is used in combination with drugs that interfere with platelet function or coagulation. Close clinical and laboratory observation for bleeding complications is recommended during and after ibritumomab therapy.
