PROVEBLUE is also used:

  • To stain bacteria to make them easier to see
  • As a visible dye to help in the diagnosis of a number of conditions
  • As a stain to dye certain body tissues during surgery

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Your doctor may have prescribed it for another reason.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with PROVEBLUE and affect how it works. These include:

  • Medicines used to treat depression known as serotonin reuptake inhibitors (SRIs) such as fluoxetine, sertraline and paroxetine and others such as fluvoxamine, escitalopram and citalopram, and serotonin and noradrenaline reuptake inhibitors (SNRIs) like clomipramine, venlafaxine, duloxetine and sibutramine, and monoamine oxydase inhibitors (MAOIs). When used in combination with these medicines PROVEBLUE may cause serotonin syndrome, which can be potentially life-threatening
  • Opioids, such as, tramadol, pethidine, and dextromethorphan. When used in combination with these medicines PROVEBLUE may cause serotonin syndrome, which can be potentially life-threatening
  • Dapsone – a medicine used to treat bacterial infections

These medicines may be affected by PROVEBLUE or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect PROVEBLUE.

4. How do I use PROVEBLUE?

If you forget to use PROVEBLUE

PROVEBLUE should be given when you are told to by your doctor or nurse. If you miss the appointment for your dose, speak with your doctor or nurse.

If you are given too much PROVEBLUE

As PROVEBLUE is always given to you in a hospital under the supervision of a doctor, it is unlikely that you will receive an overdose.
