Probenecid

pro-ben-eh-sid

What does it do?

Probenecid is used to prevent gout, and sometimes for other conditions.

Before you start

  • Tell your doctor if you have kidney, liver or stomach problems.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take probenecid regularly as directed. Take with food and a glass of water.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with probenecid including:

  • anti-inflammatories, such as diclofenac (e.g. Voltaren®), ibuprofen (e.g. Nurofen®), or aspirin (e.g. Disprin®, in doses used for pain relief). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).
  • low-dose aspirin (e.g. Cartia®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.

Other information:

  • Probenecid can cause kidney stones if you do not drink enough fluid. Discuss with your healthcare professional.
