1. What is Kaldyum and What is it Used For

Kaldyum is used for the prevention and treatment of potassium deficiency in the body. Deficiency may be caused by taking certain medications, such as diuretics (water pills), or by certain diseases (e.g., gastrointestinal disorders with vomiting or diarrhea).

2. Important Information Before Using Kaldyum

When Not to Use Kaldyum:

  • if the patient is allergic to potassium or any other component of this medication (listed in section 6);
  • if the patient has hyperkalemia (excess potassium in the blood), caused by certain diseases and medications [hyperkalemia may occur, among others, in the case of taking certain diuretics (potassium-sparing diuretics) or antihypertensive medications (e.g., ACE inhibitors), in adrenal insufficiency, kidney failure, acidosis (blood acidification, e.g., in diabetic patients), or after tissue damage (severe burns covering a large body surface area)];
  • if the patient has severe kidney disease;
  • if the patient has Addison's disease (chronic adrenal insufficiency) and is not being treated for it;
  • severe dehydration;
  • if the patient has gastrointestinal obstruction or esophageal narrowing that makes swallowing difficult.

Warnings and Precautions

Before starting to use Kaldyum, discuss it with your doctor or pharmacist.

Read the Leaflet Carefully Before Taking the Medication, as it Contains Important Information for the Patient.

  • Keep this leaflet, so you can read it again if you need to.
  • In case of any doubts, consult your doctor, pharmacist, or nurse.
  • This medication has been prescribed specifically for you. Do not pass it on to others. The medication may harm another person, even if their symptoms are the same as yours.
  • If you experience any side effects, including those not listed in this leaflet, tell your doctor, pharmacist, or nurse. See section 4.

1 of 4
Before prescribing the medication, your doctor may check your blood potassium levels and perform an EKG.
Tell your doctor if you have ulcers or other gastrointestinal diseases.
If you are taking digitalis glycosides (medications used for heart conditions), inform your doctor, as sudden discontinuation of Kaldyum may be harmful.
In some cases, your doctor may prescribe another potassium-containing medication, while in other cases, they may recommend taking an additional medication with Kaldyum.
Follow the diet prescribed by your doctor.

Kaldyum and Other Medications

Tell your doctor or pharmacist about all medications you are currently taking or have recently taken, as well as any medications you plan to take.
Be cautious when taking Kaldyum with the following medications:

  • ACE inhibitors (medications used to treat high blood pressure), potassium-sparing diuretics, as concurrent use may lead to very high potassium levels in the blood;
  • potassium-rich food products and plants (e.g., dandelion leaves and roots, bananas, tomatoes, orange juice) increase the risk of elevated potassium levels in the blood;
  • angiotensin II receptor blockers and aliskiren (medications used to treat high blood pressure and certain heart conditions) may lead to increased potassium levels in the blood;
  • proton pump inhibitors (medications that reduce stomach acid production) may lead to increased potassium levels in the blood;
  • nonsteroidal anti-inflammatory medications, anticholinergic medications, as they may exacerbate gastrointestinal side effects;
  • digitalis glycosides (used to treat heart failure), beta-adrenergic medications (used to treat high blood pressure and/or heart rhythm disorders), heparin (a medication that prevents blood clotting), cyclosporine (a cytostatic medication). Your doctor may regularly monitor your blood potassium levels if you are taking any of these medications with Kaldyum.

In case of doubts about the medications you are taking, consult your doctor.

Pregnancy and Breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before using this medication.
Kaldyum can be used during pregnancy and breastfeeding, in accordance with the indications and recommended dosage.

Driving and Operating Machinery
