If you take more Yoduk Complex than you should

Very high doses of folic acid and vitamin B12compared to Yoduk Complex are well tolerated, so there is no risk of poisoning even in accidental massive ingestion.

In the case of iodine, the administration of high doses (in the range of milligrams) or for long periods of time can produce a condition of iodism, characterized by a metallic taste, burning sensation in the mouth, painful sensitivity in teeth and gums, increased salivation, sneezing and eye irritation with swelling of the eyelids. It can also cause severe headache, cough, pulmonary edema and swelling and discomfort of the glands located below the lower jaw. The pharynx, larynx and tonsils may also become inflamed.

The signs and symptoms of iodism usually disappear spontaneously after a few days of discontinuing treatment.

In seborrheic areas, moderate eruptions may appear, rarely severe eruptions (eczema) may occur.

Gastric irritation is common whenever very high doses are ingested.

The use of large doses of potassium iodide or for long periods of time can produce hyperplasia (increase) of the thyroid gland, goiter and severe hypothyroidism.

Excessive iodine is harmful to the fetus.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service, phone 91 562 04 20, indicating the medication and the amount ingested (or go to a medical center).
