What Regiocit is and what it is used for

This drug is a haemofiltration fluid that prevents the blood from clotting during continuous kidney replacement therapy (CRRT), which is a form of dialysis treatment. This medicine is used in seriously ill patients, especially when the medicine heparin, which is usually given to prevent blood clotting, can not be used. The effect on the blood’s ability to coagulate is achieved by citrate binding to calcium in the blood.

The active substances (citrate, sodium, chloride) contained in Regiocit may also be authorized for the treatment of other diseases not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before using Regiocit

Do not use this medicine in case of:

Allergy to the active substances or any of the other ingredients (listed in section 6)

Severe hepatic impairment

Significantly reduced blood flow in the muscles

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before using this medicine.

This medicine is not intended for direct intravenous infusion. It should only be used with a machine that can perform continuous kidney replacement therapy (CRRT) which is a type of dialysis used specifically for seriously ill patients with kidney failure. The CRRT machine must be suitable for use with citrates that counteract the clotting ability of the blood.

Regiocite can be heated to 37 ° C to increase patient well-being. Heating the liquid before use may only be done with dry heat. Liquids should not be heated in water or a microwave oven. Regiocite should be inspected visually for particulate matter and discoloration before administration. Do not administer unless the liquid is clear, free of visible particles and the seal is intact.

If the cover or liquid bag is damaged, the liquid may be contaminated and must not be used. The treatment includes other fluids given by infusion in addition to this medicine. The composition or rate of administration of these other liquids may need to be adjusted to fit well with this medicine.

Your doctor will closely monitor the balance between your blood pressure and blood flow ( hemodynamics status), fluid balance, blood sugar level, electrolyte – and acid/base balance before and during treatment. Sodium, magnesium, potassium, phosphate, and calcium will be closely monitored.

The treatment will be adjusted if necessary.

Regiocite does not contain calcium . Use of Regiocite may lead to low levels of calcium in the blood (hypocalcemia).

Regiocite does not contain magnesium. The use of Regiocite may lead to low levels of magnesium in the blood (hypomagnesemia). The level of magnesium in the blood will be closely monitored and infusion of magnesium may be necessary.

Regiocite does not contain glucose. The use of Regiocite may lead to low blood glucose (hypoglycemia). Blood glucose levels should be monitored regularly.

Regiocite does not contain potassium. Serum potassium levels must be monitored before and after treatment.

Your doctor will pay special attention to the infusion rate of citrate. Too much citrate leads to low blood levels of calcium and a high pH in the blood, which can cause neurological complications and heart complications. A high pH in the blood can be corrected by adjusting the dialysis settings and by infusing 0.9% sodium chloride solution after the hemofilter or changing the composition of the CRRT fluid. Low blood levels of calcium can be treated by infusion of calcium.

Your doctor will pay special attention to whether you suffer from liver failure or shock. Because the breakdown of citrate can be significantly reduced, leading to accumulation of citrate and a low pH in the blood. Your doctor will decide if your treatment needs to be adjusted. If the ratio of total / ionized calcium exceeds 2.3, the citrate buffer should be reduced or stopped.

If Regiocit is administered to patients with hepatic impairment, frequent monitoring of pH, electrolytes, and the ratio of total / ionized calcium to systemic ionized calcium is important to avoid electrolyte and/or acid/base imbalance. Do not use it if you have severe hepatic impairment.

In case of the abnormally high volume of fluid 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 fluid and/or dialysate may be reduced.

In case of the abnormally low volume of fluid 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 fluid and/or dialysate may be increased.

Regiocite is hypoosmolar/hypotonic about common CRRT replacement fluids and should be used with caution in patients with traumatic brain injury, cerebral edema, or elevated intracranial pressure.

The user instructions must be strictly followed. Improper use of outflow ports or other flow restrictions can lead to an improper weight loss in the patient and trigger the dialysis machine alarm. If treatment is continued without addressing the cause of the problem, it could lead to patient injury or death.

Other medicines and Regiocit

Tell your doctor, pharmacist, or nurse if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. This is important because the concentration of other medicines may decrease during dialysis treatment. Your doctor will decide if the dosage of any of the medicines you are taking needs to be adjusted.

You must tell your doctor if you are taking medicines that contain:

  • Vitamin D and other drugs containing calcium and drugs containing calcium chloride or calcium gluconate; as may increase the risk of a high concentration of calcium in the blood (hypercalcemia) and may lead to a reduced anticoagulant effect.
  • Sodium bicarbonate, as can increase the level of bicarbonate in your blood.

Pregnancy, breastfeeding, and fertility


No effects on fertility are expected as sodium, chloride, and nitrate are normal components in the body.

Pregnancy and breast-feeding:

There are no data on the use of this medicine during pregnancy or breastfeeding. This medicine should only be given to pregnant or breastfeeding women if there is a clear need.

Driving and using machines

Regiocit has no known effect on the ability to drive or use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

How to use Regiocit

For intravenous use. This medicine should be used in a hospital and should only be given by healthcare professionals. The volume used, and thus the dose of the medicine depends on your condition. The dose-volume will be determined by your doctor.

The recommended rates of administration of this drug in adults and adolescents:

  • In continuous venovenous hemofiltration
    • 1-2.5 l / h with a blood flow rate between 100 and 200 ml/min.
  • In continuous venous-venous hemodiafiltration
    • 1-2 l / h with a blood flow rate between 100 and 200 ml/min.

Use in the elderly:

The recommended flow rates are the same as for adults and adolescents.

Use in children:

In neonates and infants (0 to 23 months), a dose of 3 mmol citrates per liter of blood flow Regiocit should be sought, in continuous venous-venous haemofiltration or haemodiafiltration. In children (2 to 11 years), the dosage should be adjusted according to both the patient’s weight and the blood flow rate.

Liver failure or shock:

In these conditions, the initial starting dose of citrate should be reduced.

Instructions for use

Regiocit will be given to you at a hospital. Your doctor will know how to use Regiocit.
