1. What is Neo-tomizol and what is it used for

Neo-tomizol is a medicine (antithyroid) that acts by controlling the overproduction of thyroid hormones in the thyroid gland.

It is used in children and adolescents (3-17 years) and in adults for the treatment of:

• Hyperthyroidism, i.e., a situation in which the thyroid gland is more active than normal. Carbimazole reduces the formation of thyroid hormones.

• If you are going to undergo thyroid gland surgery.
• Treatment of other conditions such as the restoration of normal thyroid function after surgical intervention in which the thyroid has been partially removed.
• Sudden worsening of hyperthyroidism symptoms (thyrotoxic crisis or thyroid storm)

2. What you need to know before you take Neo-tomizol

Do not takeNeo-tomizol

• if you are allergic (hypersensitive) to carbimazole or any of the other ingredients of this medicine (listed in section 6)
• if you are breastfeeding
• if you have blood disorders, low blood cell count such as leukocytes or neutrophils
• if you have liver disorders, high liver enzyme values, or biliary flow obstruction not caused by hyperthyroidism
• if you have suffered bone marrow damage during previous treatments with other antithyroid drugs such as thiamazole
• if you have suffered from pancreatitis (acute pancreatitis) after administration of carbimazole or thiamazole in the past.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Neo-tomizol.

If your disease symptoms worsen or persist, consult your doctor.

• Tell your doctor about the onset of any disease, especially sore throat, bleeding, mouth ulcers, fever, or malaise, as they may represent initial symptoms of a blood disorder (agranulocytosis) that can have serious consequences in patients.

• If you are pregnant, think you may be pregnant, or are planning to become pregnant.

• Tell your doctor if you experience symptoms such as (abdominal pain, loss of appetite, generalized itching) as they may be related to symptoms of liver damage.

• Carbimazole administration should be temporarily discontinued if radioactive iodine is administered.

• If you have a goiter (swelling in the front of the neck), treatment with Neo-tomizol should be carried out under strict medical control.

• Tell your doctor if you experience symptoms of mental confusion or memory loss.

• There is a risk of cross-allergy between carbimazole, the active metabolite thiamazole (methimazole), and propylthiouracil.

• Tell your doctor immediately if you experience fever or abdominal pain, as they may be signs of pancreatitis (acute pancreatitis). It may be necessary to discontinue Neo-tomizol administration.

• Neo-tomizol may harm the fetus. If you can become pregnant, use a reliable contraceptive method from the start of treatment and during treatment.

Your doctor may ask for blood tests during treatment to determine how you are responding to it.

Using Neo-tomizol with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

In particular, you should inform your doctor if you are taking:

• Theophylline used in the treatment of asthma or respiratory problems.
• Anticoagulants used to thin the blood, such as warfarin.
  • Medicines used for hypertension, heart failure (propranolol or other beta-blockers).

3. How to take Neo-tomizol

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

Do not increase or decrease the dose. Consult your doctor or pharmacist if you have doubts.

This medicine is administered orally. The tablets can be administered with a sufficient amount of liquid and can be used with or without food.

Your doctor will decide when to discontinue treatment. Occasionally, blood tests may be requested to determine how you are responding to treatment.

Radioactive iodine is another type of treatment for hyperthyroidism. If you are going to be treated with radioactive iodine, your doctor will tell you to temporarily discontinue carbimazole treatment.

If you think the effect of Neo-tomizol is too strong or too weak, inform your doctor or pharmacist.

Recommended dose:

Adults:The normal starting dose is 20-60 mg of carbimazole per day orally (4-12 Neo-tomizol tablets) depending on the degree of hyperthyroidism, divided into 2-3 doses per day. The initial treatment should be established until the patient's thyroid function normalizes.

Subsequent treatment can be administered in two different ways:

Maintenance regimen:

The maintenance dose is usually 5-15 mg of carbimazole (1-3 Neo-tomizol tablets) per day. Treatment should continue normally between 6 and 18 months.

It is recommended to perform analytical controls of thyroid function and adjust the dose if necessary to maintain normal thyroid hormone levels.

Block and replacement regimen:

The dose is maintained at the initial level of 20-60 mg of carbimazole per day orally (4-12 Neo-tomizol tablets). A dose of l-thyroxine 50-150 mg per day is administered concurrently to prevent hypothyroidism. Treatment should continue between 6 and 18 months.

Children and Adolescents (3-17 years old):

The normal starting dose is 0.75-1 mg/kg/day divided into equal doses and administered every 8 hours and adjusted according to thyroid hormone levels. The maintenance dose will be half (50%) of the initial dose (0.4-0.5 mg/kg/day).

Administration of Neo-tomizol is not recommended in children under 3 years old.

If you take moreNeo-tomizolthan you should

Overdose causes hypothyroidism, with symptoms of reduced metabolism and activation of the adenohipophysis with subsequent goiter growth. This effect can be avoided by reducing the dose when normal thyroid hormone levels are reached and, if necessary, by administering additional levothyroxine (thyroid hormone).

If you or someone else ingests more tablets than they should, contact your doctor or go to the nearest hospital emergency department immediately. Bring the box and bottle to quickly identify the product and dose.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount ingested.

Do not take a double dose to make up for forgotten doses.

If you stop takingNeo-tomizol

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
