There is an oral antidote to counteract the effects of an overdose of fluorouracil. The antidote is uridine triacetate. The antidote should be started as soon as possible after an overdose and should be continued for 5 days even when patients appear or feel well. In this case, the patient reported the overdose too late to start the antidote.
Here’s what you can do: If you or a family member are being treated for cancer and need to receive medicine using an infusion pump that is worn at home, be sure you know details about: 1) how the pump works, 2) how fast the medicine should run into the vein, 3) how long the medicine should last, and 4) the amount that should be left in the container after each day of treatment. If any errors occur, they should be reported to your doctor immediately, and emergency medical attention should be sought for any possible overdoses. Any delay in seeking medical attention is dangerous, even though you may not have any symptoms in the first few hours or even days after an overdose. Rapid reporting of an overdose allows prompt treatment with the antidote.
