What does it do?
As of May 2020, new supplies of benzbromarone have become hard to get worldwide. You will need to switch to another gout preventing medicine, such as allopurinol. Please contact your specialist or GP for advice.
Benzbromarone is used to prevent gout. It helps your kidneys remove uric acid from your blood.
Before you start
- Tell your doctor if you have liver problems, or ever had kidney stones.
- Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
How should you take it?
Take benzbromarone regularly as directed with a glass of water.
What if you forget a dose?
Take the missed dose if you remember on the same day. If not, skip the dose and carry on as normal. Do not take two doses at the same time.
Can you take other medicines?
Some medicines available without a prescription may react with benzbromarone including:
- fluconazole (e.g. Diflucan®)
Benzbromarone can increase the effect of warfarin. If you are taking warfarin and start or stop benzbromarone, your warfarin dose will need to be changed and you will need more regular INR blood tests. Discuss with your healthcare professional.
Tell your pharmacist or doctor about all medicines or treatments that you may be taking including vitamins, herbal products or recreational drugs.
