Microiodide 200 - instructions for use, dose, side effects, contraindications

Iodine refers to the essential microelements necessary for the normal functioning of the thyroid gland. When iodides enter the epithelial cells of the thyroid follicle, iodine ions under the influence of iodide-peroxidase enzyme are oxidized to form elemental iodine, which is included in the tyrosine molecule. In this case, one part of the tyrosine radicals in thyroglobulin is iodinated, resulting in the formation of tyronins, the main of which are thyroxine (T₄) and triiodothyronine (T₃). Tyronins form a complex with protein thyroglobulin, which is deposited in the colloid of the thyroid follicle. Iodine, entering the body in physiological quantities, prevents the development of endemic goiter associated with a lack of iodine in food; normalizes the size of the thyroid gland in newborns, children and adolescents; affects the ratio T₃/ T₄, level of thyroid-stimulating hormone.

Pharmacokinetics:

When ingested quickly and completely absorbed in the small intestine and within 2 hours is distributed in the intracellular space.

It accumulates mainly in the thyroid gland (concentration of iodide more than 500 μg / g tissue), as well as in the salivary and mammary glands, the mucous membrane of the stomach.

It penetrates well through the placenta.

It is excreted primarily by the kidneys (trace amounts are determined in the urine 10 minutes after admission, 80% of the dose is excreted within 48 hours, the rest - within 10-20 days), in part - with the secrets of the salivary, bronchial, sweat and other glands.

Indications:

- Prevention of endemic goiter, including during pregnancy;

- prevention of recurrence of goiter after completion of the treatment of goiter with drugs of thyroid hormones or after its surgical removal;

- treatment of diffuse euthyroid goiter in newborns, children, adolescents and adult patients of young age.

Contraindications:

- Expressed thyrotoxicosis;

- latent thyrotoxicosis (with doses exceeding 150 μg / day);

- herpetiform dermatitis;

- toxic adenoma, nodular goiter when applied at doses of more than 300 μg / day (with the exception of preoperative therapy for the purpose of blocking the thyroid gland);

- hypersensitivity to iodine.

Mikruodid 200 should not be taken with hypothyroidism, except when the development of the latter is caused by a pronounced iodine deficiency.

Prescribing the drug should be avoided with radioactive iodine therapy, if there is or suspected thyroid cancer.

Due to the presence of lactose monohydrate in the formulation, patients with rare hereditary diseases associated with intolerance to galactose, deficiency of lactase or glucose-galactose malabsorption, should not take the drug.

Carefully:Patients with impaired renal function.

Pregnancy and lactation:

During pregnancy and breastfeeding, the need for iodine increases. Mikrojodid 200 appoint or nominate under indications in those cases when receipt of an iodine from nutrition makes less than 200 mkg / sut. The drug penetrates well through the placenta and can cause the development of hypothyroidism and goiter in the fetus.

Iodine is also excreted in breast milk. Therefore, during pregnancy and breastfeeding, the drug should be taken only at recommended doses.

Dosing and Administration:

The daily dose of the drug should be taken in one meal after eating, squeezed with a large amount of liquid.

When prescribing to newborns and children under 3 years of age, it is recommended to dissolve the tablet in a small amount (1 tablespoon) of boiled water at room temperature.

If the doctor has not appointed otherwise, then follow the following dosage instructions:

Prevention of endemic goiter:

- newborns and children: 100 mcg per day,

- adolescents and adults: 100-200 mcg per day,

- during pregnancy and lactation: 150-200 mcg per day.

Prevention of recurrence of goiter after completion of treatment with drugs of thyroid hormones or after its surgical removal: 100-200 mcg daily.

Treatment of euthyroid goiter:

- newborns, children and adolescents: 100-200 mcg daily.

- adults and young patients: 300-500 mcg daily.

Taking the drug with a prophylactic purpose is carried out, as a rule, for several months or years, in the presence of indications - for life.

Treatment of goiter in newborns is an average of 2-4 weeks, children, adolescents and adults usually need 6-12 months, a long reception is possible. The duration of treatment is established by the attending physician.

Side effects:

When applying Microvoidida 200 according to the indications in the recommended doses, the occurrence of side effects is unlikely.

Allergic reactions: rarely - skin rash, edema Quincke.

Overdose:

When using the drug in a dose exceeding 150 mcg / day, latent hyperthyroidism can go into a manifest form.

With prolonged use of the drug in doses exceeding 300 mg / day, may develop iodine-induced hyperthyroidism (especially elderly patients suffering goiter for a long time, in the presence or toxic nodular goiter adenomas).

Symptoms of acute overdose: staining the mucous membranes in brown, reflex vomiting, abdominal pain and diarrhea (possibly, melena). In severe cases, the development of dehydration and shock is possible.

Treatment for acute overdose: gastric lavage, administration of sodium thiosulfate, symptomatic therapy of water-electrolyte balance disturbance, antishock therapy.

Chronic overdose can lead to the development of the phenomenon of "iodism": "metallic" taste in the mouth, edema and inflammation of mucous membranes (rhinitis, conjunctivitis, gastroenteritis, bronchitis), acne, dermatitis, salivary edema, fever, nervous excitability.

Treatment for chronic overdose: cancellation of the drug.

Interaction:

Simultaneous administration of antithyroid medications weakens the effect of potassium iodide (mutually).

Perchlorate and potassium thiocyanate inhibit the absorption of iodine by the thyroid gland. Thyrotropic hormone improves the absorption of iodine by the thyroid gland and stimulates the production of its hormones.

Simultaneous reception of inhibitors of angiotensin-converting enzyme (including captopril, enalapril, lisinopril) increases the risk of hyperkalemia. High doses of iodine in combination with potassium-sparing diuretics can lead to hyperkalemia.

Simultaneous administration of iodine therapy in high doses and lithium preparations promotes the development of goiter and hypothyroidism.

Reduces the grip of the thyroid gland 1311 and 1231.

Special instructions:

Before the beginning of treatment it is necessary to exclude malignant lesion of the thyroid gland, hyperthyroidism or nodal toxic goiter.

Against the background of drug therapy in patients with impaired renal function, it is possible to develop hyperkalemia (periodic monitoring of the level of potassium in the blood).
