3. How to take Lidervit film-coated tablets

Follow exactly the administration instructions of this medication indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

The recommended daily dose is 1 tablet per day, taken before meals.

Your doctor will determine the duration of treatment with Lidervit film-coated tablets. Do not suspend or prolong it.

If you take moreLidervitfilm-coated tablets than you should

Very high doses of folic acid and vitamin B12, higher than those of Lidervit film-coated tablets, are well tolerated, so intoxication is very unlikely even in case of accidental massive ingestion.

In case of poisoning by the components of Lidervit, the symptoms that may occur are alterations in sleep patterns, difficulty concentrating, irritability, hyperactivity, and confusion, due to excess folic acid.

Excess vitamin B12 can cause mild and transient diarrhea, transient exanthema, itching, sensation of generalized swelling, formation of thrombi in small veins, anaphylaxis, pulmonary edema, and heart failure.

In the case of iodine, administration of high doses or for long periods can produce a picture of iodism, characterized by metallic taste, burning in the mouth and throat, painful sensitivity in teeth and gums, increased salivation, inflammation of the nasal mucosa, sneezing, and eye irritation with swelling of the eyelids. It can also cause severe headache, cough, edema in the lungs, and swelling and discomfort of the parotid and submaxillary glands (glands located below the lower jaw). The pharynx, larynx, and tonsils can also become inflamed. In seborrheic areas, moderate eruptions (rashes) may appear, although rarely severe. Gastric irritation is common when very high doses are ingested and can cause diarrhea, sometimes with blood. The use of large doses of potassium iodide or for long periods can cause an increase in the size of the thyroid gland, goiter, and severe hypothyroidism.

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

Regarding excess iron, the initial symptoms are related to the irritating contact of iron with the intestinal mucosa: nausea, vomiting, diarrhea, epigastric pain, hematemesis, and rectorrhagia. This situation can evolve, and subsequent complications are hypotension, coma, liver necrosis, and kidney failure.

In case of overdose or accidental ingestion, consult your doctor or pharmacist or call the Toxicology Information Service, Telephone 915 620 420, indicating the medication and the amount used.
