Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket, health food shop, herbalist or naturopath.
Some medicines and PROVEBLUE may interfere with each other. 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
- 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.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while being given this medicine.
How PROVEBLUE is given
PROVEBLUE must only be given by a doctor or nurse.
How it is given
PROVEBLUE can be given in two ways depending upon what it is being used for. It can be given:
- as an injection into a vein either diluted or undiluted
- by mouth after dilution
How much is given
Your doctor will decide what dose of PROVEBLUE you will receive and how long you will receive it.
This depends on your medical condition and other factors such as your weight.
Sometimes only a single dose of PROVEBLUE is required.
If you are given too much (overdose)
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.
Symptoms of an overdose are the same as side effects but may be more severe. The symptoms of a side effect are listed under Side effects below.
If you notice any symptoms of an overdose immediately contact your doctor or go to the Emergency Department at the nearest hospital.
Contact the Poisons Information Centre on 13 11 26 for further advice on overdose management.
While you are being given PROVEBLUE
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you have been given PROVEBLUE.
Tell any other doctors, dentists, and pharmacists who treat you that you have been given this medicine.
If you become pregnant while being given this medicine, tell you doctor immediately.
If you are about to have any blood tests, tell your doctor that you have been given this medicine. It may interfere with the results of some tests.
Keep all of your doctor's appointments so that your progress can be checked.
Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Things to be careful of
Be careful driving or operating machinery until you know how PROVEBLUE affects you. This medicine may cause dizziness in some people. If you feel dizzy do not drive, operate machinery or do anything else that could be dangerous.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
PROVEBLUE can cause a photosensitivity reaction in the skin (sunburn-like reaction) when exposed to strong light sources, such as lights in operating rooms.
Protective measures against light exposure should be taken.
Tell your doctor or nurse as soon as possible if you do not feel well while you are being given PROVEBLUE.
