magnesium chloride hexahydrate, sodium chloride, sodium bicarbonate, potassium chloride, disodium phosphate dihydrate 

What Biphozyl Hemodialysis / Hemofiltration Fluid is and what it is used for

This medicine is a fluid for dialysis treatment ( hemofiltration, hemodialysis, and hemodiafiltration) which is used to remove waste products from the blood when the kidneys are not working. This medicine is used in hospitals during intensive care with continuous kidney replacement therapy (CRRT).

This medicine is especially used to treat critically ill patients with acute kidney injury who have:

  • a normal potassium content (normal kalemi) in the blood
  • a normal pH in the blood
  • a normal phosphate level (normal phosphatemia) in the blood
  • a high calcium content ( hypercalcemia ) in the blood.

This medicine can also be used

  • when other bicarbonate sources are available or when citrate is used to prevent blood clotting in the extracorporeal pathway.
  • in case of drug poisoning or intoxication of dialyzable or filterable substances.

The active substances contained in Biphozyl may also be approved for the treatment of other diseases not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professionals if you have any further questions, and always follow their instructions.

2. What you need to know before you use Biphozyl, a hemodialysis/haemofiltration fluid 

Do not use Biphozyl, a hemodialysis/haemofiltration fluid 

Do not use Biphozyl if you have:

  • allergy to any of the active substances or any of the other ingredients (listed in section 6)
  • a low calcium level (hypocalcemia) in the blood
  • a high potassium content ( hyperkalemia ) in the blood
  • a high phosphate level ( hyperphosphatemia ) in the blood.

Warnings and cautions


Talk to your doctor, pharmacist, or nurse before using Biphozyl.

Biphozyl should not be used in patients with high blood potassium levels. The potassium content in your blood will be monitored regularly before and during treatment.

Because Biphozyl contains potassium, high levels of potassium in the blood may occur shortly after starting treatment. Your doctor will slow down the infusion rate and check that the potassium level has returned to the desired level. If the condition does not resolve, the doctor must immediately stop administering one. A potassium-free fluid may be used briefly to restore blood potassium levels.

Because Biphozyl contains phosphate, a high level of phosphate in the blood may occur shortly after starting treatment. Your doctor will slow down the infusion rate and check that the phosphate content has returned to the desired level. If the condition does not resolve, the doctor must immediately stop administering one.

Because Biphozyl does not contain glucose, low blood glucose levels may occur during treatment. Blood glucose levels will be monitored regularly. If low blood glucose levels occur, your doctor may use a fluid that contains glucose. Other corrective measures may be necessary to maintain the desired blood glucose level.

Your doctor will regularly check the electrolyte and acid/base parameters of patients treated with Biphozyl. Biphozyl contains hydrogen phosphate which is a weak acid that can affect your acid/base balance. If a decrease in blood bicarbonate levels develops or worsens during treatment with Biphozyl, your doctor will slow down the infusion rate. If the condition does not resolve, the doctor must immediately stop administering one.

The user instructions must be strictly followed.

The liquids in the two chambers must be mixed before use.

Use only with a CRRT dialysis machine.

Use only if the cover and fluid bag are undamaged. All seals must be intact. The use of contaminated fluid may cause sepsis and shock.

Use only with a suitable system for extracorporeal kidney replacement.


This medicine is calcium-free and may cause hypocalcemia. Infusion of calcium may be necessary.

Biphozyl can be heated to 37 ° C to increase patient comfort. Heating of the liquid before use must be carried out before preparation with only dry heat. Liquids must not be heated in water or in a microwave oven. Biphozyl should be visually inspected visually for particulate matter and discoloration prior to administration. Do not administer if the liquid is not clear or if the seal is not intact.

Your doctor will closely monitor the balance between your blood pressure and blood flow (hemodynamic status), fluid balance, electrolyte and acid/base balance throughout the procedure, including all fluid ( intravenous infusion ) and all fluid withdrawals (urine production), including those not directly related to CRRT.

This medicinal product has a hydrogen carbonate content that is in the low direction within the normal range of hydrogen carbonate content in the blood. This is suitable when citrate is used to prevent the blood from clotting because citrate is broken down into bicarbonate, or when pH values ​​(measures of the body’s acidity) have been restored to normal. The need for buffer should be evaluated by repeated measurements of the blood acid/base parameter and examination of the overall treatment. A liquid with a higher hydrogen carbonate content may be necessary.

In case of abnormally high fluid volume in the body ( hypervolemia ), the rate of net ultrafiltration prescribed for the CRRT unit may be increased, and/or the rate of administration of fluids other than replacement fluids and/or dialysis fluid may be reduced.

In case of abnormally low fluid volume in the body ( hypovolemia ), the rate of net ultrafiltration prescribed for the CRRT unit may be reduced, and / or the rate of administration of fluids other than replacement fluids and / or dialysis fluid may be increased.

Children and young people

No specific side effects are expected in children when using this medicine.

Other medicines and Biphozyl, hemodialysis/haemofiltration fluid 

Tell your doctor, pharmacist, or nurse if you are taking, have recently taken, or might take any other medicines, including medicines obtained without a prescription. This is important because the number of other medicines can be reduced in the body during dialysis treatment. Your doctor will decide if the dose of any of the medicines you are taking needs to be adjusted.

It is especially important that you tell your doctor if you use any of the following:

  • Additional sources of phosphate (eg nutritional fluids) may increase the risk of high phosphate levels in the blood ( hyperphosphatemia ).
  • Sodium bicarbonate may increase the risk of excess bicarbonate in the blood ( metabolic alkalosis ).
  • When citrate is used to counteract blood coagulation, as it can lower the calcium concentration in the blood.
