Potaba is an antifibrosis agent, which acts by increasing oxygen uptake by the tissues.

structure (e.g. benzocaine, procaine, ethyl parahydroxybenzoate) or any of the other
ingredients of this medicine (listed in section 6)
• if you have kidney disease
• if you have a raised level of potassium in your blood (each sachet contains 669 mg potassium)
• if you are taking sulfonamides or combinations of sulfonamides with other antibiotics (e.g.
sulfamethoxazole, sulfadimidine or co-trimoxazole)
• if you have severe liver damage
Warnings and precautions
You may need to stop taking Potaba Powder for a while if you are not eating enough food (e.g.
if you are fasting, have anorexia or are feeling sick). This is to reduce the risk of your blood
sugar levels falling too low (see section 4).
Your condition will need to be carefully monitored by your doctor to ensure you do not become
over-sensitive to the medication, in which case treatment with Potaba will be stopped.
Symptoms of this include fever, rash and tiredness.
Talk to your doctor or pharmacist before taking Potaba Powder:
• if you have kidney problems or any other condition that may cause high blood levels of
potassium, Potaba Powder should be used with caution because of the risk of high levels of
blood potassium, which can cause abnormal heart rhythm
