Relevance: 08.04.2023 Reviewer: Shkutko P.M., M.D., in

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.

Consumer:

Ifosfamide may cause central nervous system side effects such as drowsiness, confusion, hallucinations, blurred vision, abnormal behavior, abnormal muscle movements, seizures, and even coma in some cases. Combining it with other medications that can also affect the nervous system such as chlorpheniramine may increase the risk and/or severity of these effects. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid driving, operating machinery, or engaging in potentially hazardous activities requiring mental alertness and motor coordination until you know how the medications affect you. 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.

Professional:

MONITOR: Centrally-acting agents such as antiemetics, sedatives, narcotics, or antihistamines may add to the neurotoxic effects of ifosfamide. Administration of ifosfamide can cause CNS toxicity, which necessitates careful monitoring of the patient. Neurologic manifestations include somnolence, confusion, hallucinations, blurred vision, psychotic behavior, extrapyramidal symptoms, urinary incontinence, seizures, and in some instances, coma. There have also been reports of peripheral neuropathy. Ifosfamide neurotoxicity may occur within a few hours to a few days after initial administration and typically resolves within 48 to 72 hours of ifosfamide discontinuation. However, symptoms may persist for longer periods of time, and recovery has occasionally been incomplete. Fatal outcomes have been reported. There have also been reports of recurrence of CNS toxicity after several uneventful treatment courses.

MANAGEMENT: Due to the potential for additive effects, centrally-acting agents should be used with caution in combination with ifosfamide. Patients should be advised to avoid driving, operating machinery, or engaging in potentially hazardous activities requiring mental alertness and motor coordination until they know how the medications affect them. If ifosfamide-induced encephalopathy occurs, both ifosfamide and non-essential concomitant CNS agents should be discontinued. Supportive therapy should be initiated and maintained until complete resolution of neurotoxicity.
