Boi-k aspartic belongs to a group of medicines called "mineral supplements".

BOI-K aspartic is indicated in the following situations:

Treatment and prophylaxis of hypokalemia (potassium deficiency) in situations such as:

  • Potassium losses caused by treatment with diuretics (medicines that increase urine elimination), corticosteroids, and derivatives (medicines that reduce inflammation).
  • Potassium losses caused by vomiting, diarrhea, kidney problems, hyperaldosteronism (excessive production of the hormone aldosterone), and intense sweating (due to climate or physical exercise).
  • Situations where there is a deficit in potassium intake, such as malnutrition, deficient diets.

Situations where an additional intake of vitamin C is necessary.

2. Before taking BOI-K aspartic effervescent tablets

Do not take BOI-K aspartic effervescent tablets

  • If you are allergic (hypersensitive) to potassium hydrogen carbonate, ascorbic acid, aspartic acid, or any of the other components of BOI-K aspartic.
  • If you have high potassium levels in the blood (hyperkalemia).
  • If you have any of the following gastrointestinal diseases (stomach and intestine): intestinal obstruction, stenosis in the digestive tract, paralytic ileus, or any other process that hinders or prevents passage through the stomach or intestine.
  • If you have a peptic ulcer or gastrointestinal bleeding, as excessive potassium can cause gastrointestinal perforation.
  • If you have severe kidney failure, as potassium can accumulate in the kidney.
  • If you have any disease that causes a decrease in urine production.
  • If you have Addison's disease (a disease in which the production of hormones such as cortisol and aldosterone decreases).

Be careful withBoi-kaspartic effervescent tablets

  • If you have had kidney stones or gout.
  • During treatment, your doctor should monitor your potassium levels in the blood, especially in the case of the elderly, patients with heart disease, or kidney failure.
  • If you are being treated with amiloride, triamterene, or spironolactone, which are types of diuretics (medicines that increase urine elimination), hyperkalemia (high potassium levels in the blood) may occur.
  • If you are being treated with digitalis (medicines for heart problems), BOI-K aspartic can increase the toxicity of digitalis.
  • If you have had a peptic ulcer, as oral administration of potassium (a component of BOI-K aspartic) can cause irritation to the gastrointestinal mucosa.

If you take more than 1 g of vitamin C (ascorbic acid) per day, you may experience diarrhea, kidney stones, and abdominal cramps. There is also a risk of forming stones and precipitating acute gout attacks in individuals who are prone to them.

During treatment, your doctor will assess whether you need to undergo periodic electrocardiogram reviews, as if there are any alterations, the administration of potassium should be suspended.

Use in elderly people

Your doctor should monitor your potassium levels in the blood to rule out kidney failure.

In any of these situations, inform your doctor before taking BOI-K aspartic.

Use of other medicines

Inform your doctor or pharmacist if you are using or have recently used any other medicine, including those purchased without a prescription, homeopathic medicines, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose.

Consult your doctor if you take Boi-k aspartic with any of the following medicines:

  • Amiloride, triamterene, or spironolactone (medicines that increase urine elimination), ACE inhibitors (medicines for high blood pressure), angiotensin II receptor antagonists (medicines for high blood pressure), NSAIDs (non-steroidal anti-inflammatory medicines), beta-blockers (medicines used for heart rhythm disorders and high blood pressure), cyclosporine (a medicine used in transplants), heparin (to prevent blood coagulation). These medicines can promote potassium accumulation and lead to hyperkalemia (high potassium levels in the blood).
  • Laxatives, corticosteroids, amphotericin B (an antifungal antibiotic), aminoglycosides (gentamicin), penicillins (penicillin, carbenicillin, mezlocillin, piperacillin, ticarcillin), or polymyxin B (all of which are antibiotics). These medicines can lead to increased potassium elimination, potentially causing hypokalemia (low potassium levels in the blood).
  • Digitalis (medicines for heart problems), BOI-K aspartic can increase their toxicity.
  • Parenteral calcium salts, as cardiac rhythm disorders may occur.
  • Insulin or bicarbonate, as they can cause hypokalemia (low potassium levels in the blood).
  • Vitamin C (ascorbic acid) at high doses can alter the action of the following medicines: antidepressants, anticoagulants, high doses of salicylates, sulfonamides, trimethoprim/sulfamethoxazole, or hormonal contraceptives.

Never take another medicine on your own initiative without your doctor's recommendation, as some combinations should be avoided and in other cases, it may be necessary to adjust the treatment dose.

Interference with diagnostic tests

If you are going to undergo any diagnostic test (blood test, urine test, etc., including tests with reactive strips), inform your doctor that you are being treated with Boi-k aspartic, as it may alter the results.
