Product description

Vigalex Max is a preparation whose active substance is vitamin D3 (cholecalciferol), supporting the bone formation process. The indication for the use of the preparation is the prevention of vitamin D deficiency and conditions resulting from vitamin D deficiency in adults with obesity. Each tablet contains 40 mg of colecalciferol. Vitamin D3 (cholecalciferol) is produced in the body in the skin by the action of UV rays and is supplied with food. Vitamin D deficiency is associated with disorders of bone calcification (rickets) or loss of calcium from the bones (osteomalacia).

Side effects

This medicine can cause side effects, although not everybody gets them.

Not known (frequency cannot be estimated from the available data):

  • constipation
  • flatulence
  • nausea,
  • stomach pain or diarrhea
  • itchy skin
  • rash or hives
  • Hypercalcaemia (too much calcium in the blood) and hypercalciuria (excessive excretion of calcium in the urine) occur with prolonged use of high doses. Fatalities have been reported in individual cases.


  • The use of antacids containing aluminum, intended for the treatment of hyperacidity, when used together with Vigalex Max may increase the concentration of aluminum in the blood, increasing the risk of aluminum toxicity on bones.
  • Taking antacids containing magnesium simultaneously with Vigalex Max may increase the concentration of magnesium in the blood.
  • Certain antiepileptic, sedative or hypnotic preparations (containing phenytoin or barbiturates), used simultaneously with Vigalex Max, may reduce its effectiveness.
  • Certain diuretics can lead to hypercalcaemia (increased calcium levels) caused by decreased renal excretion of calcium. Serum and urine calcium levels should be monitored during long-term treatment.
  • Taking glucocorticosteroids (adrenal cortex hormones) at the same time may suppress the effect of Vigalex Max.
  • Vigalex Max may increase the effect and toxicity of digitalis glycosides, which creates a risk of developing cardiac arrhythmias. In this case, the physician should monitor the levels of calcium in the serum and urine of the patients, and perform periodic ECG tests.
  • The use of metabolites or analogues of vitamin D (e.g. calcitriol) and Vigalex Max is possible only on the recommendation of a doctor, only in exceptional cases, provided that serum calcium levels are controlled.
  • Rifampicin and isoniazid may reduce the effectiveness of Vigalex Max.

Warnings and Precautions

  • Talk to your doctor or pharmacist about the use of Vigalex Max.
  • Vigalex Max should be used under the supervision of a doctor:
  • while taking also other products containing vitamin D, because additional doses of vitamin D can only be taken under medical supervision,
  • if you have sarcoidosis (an immune system disease that can increase the amount of vitamin D in your body)
  • if you have kidney problems
  • during treatment with cardiac glycosides or diuretics,
  • when treatment with vitamin D is long-term (more than 3 months), as in this case the doctor should monitor the patient's serum and urine calcium levels, and check the kidney function by measuring the level of creatinine in the blood.
