2. BEFORE YOU TAKE GENFURA
Do not take Genfura and tell your doctor if:

• you have problems with your kidneys (other than infection). Your doctor will assess whether you may take Genfura depending on how well your kidneys are working.
• you have a blood problem known as porphyria where you may have too many red blood cells
• you have glucose-6-phosphate dehydrogenase (G6PD) deficiency. This is a genetic disorder where the red blood cells are broken down under stressful conditions or due to taking medicines
• you are breast-feeding an infant with G6PD deficiency
• you are in the last month of your pregnancy.
This medicine should not be given to infants under 3
months old.

• you have anaemia or diabetes
• you have a vitamin B deficiency, especially folate

medicine.
Having tests
Your doctor will monitor you closely for any effects on your liver, lungs, blood or nervous system, especially if you are taking Genfura for long-term treatment.
If you are having urine tests, tell the doctor that you are taking Genfura as it may interfere with the results.
Taking other medicines
Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, even medicines bought without a prescription. This is because Genfura can affect the way some other medicines work. Also, some medicines can affect the way Genfura works.
In particular, tell your doctor or pharmacist if you are taking any of the following:
• Other medicines to treat bacterial infections such as Quinolone antibiotics (e.g. Norfloxacin)
• Medicines to make your urine less acidic such as Sodium Bicarbonate
• Antacids for indigestion or heartburn such as Magnesium Trisilicate
• Barbiturates or Phenytoin for epilepsy
• Probenecid or Sulfinpyrazone to treat pain and swelling of the joints (gout)
• Medicines called Anticholinergics (e.g. Atropine) used for lots of different types of illness such as eye, kidney, breathing or bowel problems
• Carbonic Anhydrase Inhibitors
(e.g. Acetazolamide) to treat increased eyeball pressure (glaucoma).
Genfura can make birth control pills less effective. An additional form of contraception should be used.
Taking Genfura with food and drink
Genfura should be taken with food or milk. This lowers the chance of getting an upset stomach.
Avoid alcohol whilst taking Genfura.
Pregnancy and breast-feeding
