1. what duosol with 4 mmol/l potassium is and what it is used for

Duosol with 4 mmol/l Potassium is a solution for haemofiltration. It is intended for use in patients with acute kidney failure, when the kidneys are no longer able to remove waste products from the blood. Continuous haemofiltration is a procedure which is used to remove the waste products from the body which would otherwise be excreted via the kidneys in urine. The solution corrects the fluid balance and ensures that salt (electrolyte) losses are replaced following treatment.

2. what you need to know before you are given duosol with 4 mmol/l potassium

Duosol with 4 mmol/l Potassium should not be given if – you have an abnormally high blood potassium level (hyperkalaemia)

• – your blood contains abnormally low acid levels (metabolic alkalosis).

The haemofiltration procedure itself should not be used if – you have kidney failure in combination with a very high metabolic turnover (hypercatabolic state), in which situation the accumulation of waste products in your body can no longer be corrected by haemofiltration

• – you have poor blood flow from the site of insertion of the cannula in the vein

• – you have a high risk of bleeding because you receive drugs to prevent blood clotting (systemic anticoagulation).

Warnings and precautions

Talk to your doctor or pharmacist before you are given Duosol with 4 mmol/l Potassium.

Before and during haemofiltration your blood pressure, fluid balance, salt (electrolyte) balance, acid-base balance and kidney function will be monitored. Your blood sugar and phosphate levels will regularly be checked.

Furthermore serum potassium concentration will be monitored before and during haemofiltration.

Other medicines and Duosol with 4 mmol/l Potassium Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

The level of other medicines in your blood may be reduced during haemofiltration and your doctor will take this into account.

Interactions with other medicines can be avoided by ensuring that the correct dose of the solution for haemofiltration is used and by careful monitoring.

The following interactions will be considered:

• – Infusions given in intensive care may change the composition of your blood and your fluid status.

• – Toxic effects of certain medicines used to treat heart weakness (medicines containing digitalis) may not become apparent if your potassium or magnesium levels are too high or your calcium levels are too low. If those levels are corrected by haemofiltration, the toxic effects may then occur and cause for instance an abnormal heart rhythm. If you have low potassium levels or high calcium levels in your blood, digitalis may have toxic effects at doses lower than those usually used for therapy.

• – Vitamin D and medicines containing calcium can increase the risk that the calcium level in the blood rises to abnormally high values (hypercalcaemia).

• – Additional use of sodium hydrogen carbonate can increase the risk of abnormally low acid levels in the blood (metabolic alkalosis).

3. how to use duosol with 4 mmol/l potassium

You will only be given this medicine under the direction of a doctor with experience in haemofiltration techniques.

Your doctor will decide on the proper dose for you, taking into account your clinical status, your body weight and your metabolic condition. Unless otherwise prescribed, a filtration rate of 20–25 ml/kg body weight per hour is recommended for patients of all ages for the removal of those substances which are normally excreted in the urine.

You are given the ready-to-use solution for haemofiltration via the tubing of the haemofiltration apparatus (the so-called extracorporeal circulation) using an infusion pump.

The treatment of acute kidney failure is carried out for a limited time period and ends when kidney function is fully restored.

If you are given more Duosol with 4 mmol/l Potassium than recommended

There have been no reports of life-threatening situations following the administration of the prescribed dose of this medicine. The administration can be stopped immediately, if required.

Unbalanced administration can result in too much or too little fluid being present in the body (hyperhydration or dehydration). This situation can become apparent through changes in blood pressure or pulse.

Hydrogen carbonate overdose can occur if a too large volume of solution for haemofiltration is given. This can lead to abnormally low acid levels in the blood (metabolic alkalosis), less calcium dissolved in the blood (decrease of ionised calcium) or muscle cramps (tetany).

An overdose can be the cause of a heart failure and/or congested lung and can cause changes in the salt (electrolyte) balance and acid-base balance.

Your doctor will decide on the appropriate treatment.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

At present, no side effects associated with this medicine have been reported, however, the following side effects are possible. The frequency of these side effects is not known (cannot be estimated from the available data):

Too much or too little fluid in the body (hyperhydration or dehydration), abnormal salt (electrolyte) levels – for instance too much potassium in the blood (hyperkala-emia) -, low blood phosphate levels (hypophospha-taemia), high blood sugar levels (hyperglycaemia), abnormally low acid levels in the blood (metabolic alkalosis), high or low blood pressure (hypertension or hypotension), feeling sick (nausea), being sick (vomiting) and muscle cramps.

Reporting of side effects

If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

Instructions for preparation of the ready-to-use solution for haemofiltration

The container and the solution must be visually inspected prior to use. The solution for haemofiltration must only be used if the container (outer wrap and two-chamber bag), peel seam and connectors are undamaged and intact and if the solution is clear and colourless and free from visible particles.

Remove outer wrap only immediately before use.

Administration of the ready-to-use solution for haemo filtration

The solution for haemofiltration should be warmed to approximately body temperature by an integrated or external heater. The solution must not be infused under any circumstances if below room temperature.

During application of this medicinal product, white calcium carbonate precipitation has been observed in the tubing lines in rare cases, particularly close to the pump unit and the heating unit. Therefore, the solution in the tubing lines should be closely visually inspected every 30 min during haemofiltration in order to ensure that the solution in the tubing system is clear and free from precipitate. Precipitations may occur also with substantial delay after start of treatment. If precipitate is observed, the solution and the tubing lines must be replaced immediately and the patient carefully monitored.

For single use only. Any unused portion of solution and any damaged containers must be discarded.

Press with both hands on the smaller chamber of the bag until the peel seam opens fully along its entire length.

4 Ensure the contents are thoroughly mixed by twisting the bag 5 times back and forth.
