Frequently asked questions

How should Kaldyum be taken?

The medicine should be used strictly according to the doctor's instructions. The capsule should usually be swallowed whole with a glass of water, during or after a meal. If the daily dose exceeds 2 capsules, it should be divided into at least two portions.

When should you not use this medicine?

It must not be used in case of hypersensitivity to potassium or any of the ingredients of the medicine, excess potassium in the body (hyperkalemia), severe kidney disease, Addison's disease (untreated), acute dehydration, or gastrointestinal obstruction or esophageal stricture.

Can this medicine be used with other preparations?

Caution should be exercised, as some drugs (e.g., ACE inhibitors, potassium-sparing diuretics, antihypertensive drugs, or digitalis glycosides) may interact and lead to a dangerous increase in potassium levels. It is also important to avoid consuming foods very rich in potassium (e.g., bananas, tomatoes, orange juice) during treatment.

What side effects may Kaldyum cause?

Nausea, vomiting, diarrhea, or abdominal pain may occur. You must immediately discontinue use and contact a doctor if black stools or symptoms of high potassium concentration appear, such as burning, tingling, muscle weakness, irregular heartbeat, or low blood pressure.

What should you do in case of overdose?

If you take too large a dose, you must contact a doctor immediately. Symptoms of overdose include, among others, muscle weakness, a drop in blood pressure, and cardiac arrhythmias.

1. What Kaldyum is and what it is used for

Kaldyum is used for the prevention and treatment of potassium deficiency in the body. Potassium deficiency
may be caused by taking certain medicines, e.g. diuretics (water tablets), or
certain diseases (e.g. gastrointestinal disorders associated with vomiting or
diarrhoea).

2. Important information before using Kaldyum

When not to use Kaldyum

  • if the patient is allergic to potassium or any of the other ingredients of this medicine (listed in section 6);
  • if the patient has hyperkalemia (excess potassium in blood serum), caused by certain diseases or medications [hyperkalemia may occur, for example, when taking certain diuretics (potassium-sparing diuretics) or antihypertensive drugs (e.g. so-called ACE inhibitors), in adrenal cortex insufficiency, kidney failure, acidosis (blood acidification, e.g. in diabetic patients), or after tissue injuries (severe burns affecting a large body surface)];
  • if the patient has severe kidney disease;
  • if the patient has Addison's disease (chronic adrenal insufficiency) and is not being treated for it;
  • acute dehydration;
  • if the patient has gastrointestinal obstruction or esophageal stricture that makes swallowing difficult.

Warnings and precautions
Before starting treatment with Kaldyum, discuss it with your doctor or pharmacist.
Before prescribing the medicine, the doctor may check blood potassium levels and perform an ECG.
Inform your doctor if you have ulcers or other gastrointestinal disorders.
If you are taking cardiac glycosides (medicines used in heart diseases), inform your treating physician, as abruptly stopping Kaldyum may be harmful.
In certain conditions, your doctor may prescribe a different potassium-containing medicine; in other cases, additional medication may be recommended to be taken together with Kaldyum.
Follow the diet prescribed by your doctor.

Kaldyum and other medicines
Tell your doctor or pharmacist about all medicines you are currently taking, have recently taken, or plan to take.
Exercise caution when using Kaldyum together with the following medicines:

  • ACE inhibitors (medicines used to treat hypertension), potassium-sparing diuretics, as concomitant use may lead to very high potassium levels in blood serum;
  • potassium-rich food products and herbal remedies (e.g. leaves and roots of dandelion, bananas, tomatoes, orange juice) which increase the risk of elevated serum potassium levels;
  • angiotensin II receptor blockers and aliskiren (medicines used to treat high blood pressure and certain heart conditions) which may lead to increased serum potassium levels;
  • proton pump inhibitors (medicines that reduce gastric acid secretion) which may lead to increased serum potassium levels;
  • nonsteroidal anti-inflammatory drugs, anticholinergic medicines, as they may exacerbate adverse effects in the gastrointestinal tract;
  • cardiac glycosides (used in the treatment of heart failure), beta-adrenergic agents (used to treat hypertension and/or cardiac arrhythmias), heparin (a blood anticoagulant), cyclosporine (a cytostatic medicine). Your doctor may perform regular monitoring of serum potassium levels when any of these medicines are used concomitantly with Kaldyum.

If you have any doubts regarding medicines you are taking, consult your doctor.
