Levothyroxine sodium
Levothyroxine, the active substance of Levothyroxine Accord, is a synthetic thyroid hormone intended for the treatment of thyroid diseases and disorders. It has the same effect as the thyroid hormones that occur naturally in the body. Levothyroxine Accord is used:
Levothyroxine Accord 25 micrograms, 50 micrograms, 75 micrograms, 88 micrograms, and 100 micrograms are also used to balance thyroid hormone levels in patients who are taking antithyroid drugs due to excessive thyroid hormone production. Levothyroxine Accord 100 micrograms, 150 micrograms, and 200 micrograms may also be used in tests to assess thyroid function. Levothyroxine Accord, 12.5 micrograms:
Levothyroxine Accord should not be taken with antithyroid drugs if the patient is pregnant (see "Pregnancy and breastfeeding" below).
Before starting treatment with Levothyroxine Accord, the patient should inform their doctor about any of the following heart diseases:
Treatment of these disorders is necessary before starting treatment with Levothyroxine Accord and before performing a thyroid suppression test. During treatment with Levothyroxine Accord, it is necessary to frequently check thyroid hormone levels. In case of doubts about whether the patient has any of the above diseases or if they are not treated, the patient should consult their doctor. The doctor will perform the necessary tests to determine whether the patient has adrenal or pituitary disorders or a certain type of thyroid disorder with uncontrolled excessive production of thyroid hormones (autonomous thyroid function), as in such cases, appropriate treatment may be necessary before starting treatment with Levothyroxine Accord and before performing a thyroid suppression test. After starting levothyroxine treatment in premature infants with very low birth weight, it is necessary to regularly monitor blood pressure, as a sudden drop in blood pressure (called circulatory collapse) may occur. If it is necessary to change the medicine to another levothyroxine-containing medicine, a disruption of thyroid hormone balance may occur. The patient should consult their doctor if they have any questions about changing medicines. During the transition period, close monitoring of clinical and biochemical parameters is necessary. The patient should tell their doctor if they experience any side effects, as it may be necessary to increase or decrease the dose.
Disruption of thyroid hormone balance may occur when changing the levothyroxine-containing medicine to another. If the patient has any questions about changing the medicine to another, they should consult their doctor. Close monitoring of the patient (clinical and biological assessment) is necessary during the transition period. If any side effects occur, the patient should consult their doctor, as it may be necessary to increase or decrease the dose.
The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take, as Levothyroxine Accord may affect the action of these medicines:
The patient should ensure that the recommended time intervals are observed when taking any of the following medicines:
These medicines may reduce the effect of Levothyroxine Accord, so the patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take:
These medicines may enhance the effect of Levothyroxine Accord, so the patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take:
These medicines may affect the action of Levothyroxine Accord, so the patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take:
In this situation, regular thyroid hormone testing and dose adjustment may be necessary. If the patient is taking amiodarone (a medicine used to treat heart rhythm disorders), they should tell their doctor, as this medicine may affect thyroid function. The patient should tell their doctor about taking Levothyroxine Accord if they need to undergo a diagnostic or imaging test with a contrast agent containing iodine, as this test involves the administration of an injection that affects thyroid function. The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, including those that are available without a prescription. Thyroid hormones should not be used to reduce weight. Taking them will not lead to weight loss if thyroid hormones are maintained at the proper level. Increasing the dose without consulting a doctor may lead to serious and life-threatening side effects, especially when taking other weight loss medicines. If the patient is currently taking or has recently taken biotin, they must inform their doctor or laboratory staff if they are to undergo thyroid hormone laboratory tests. Biotin may affect the results of laboratory tests (see "Warnings and precautions").
If the patient's diet includes soy products, they should tell their doctor, especially if they change the amount of these products they consume. Soy products may reduce the absorption of Levothyroxine Accord from the gut, and therefore, it may be necessary to modify the dose of Levothyroxine Accord.
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine. Adequate amounts of thyroid hormone are necessary for a normal pregnancy. Therefore, during pregnancy, the patient should continue taking Levothyroxine Accord. During pregnancy, Levothyroxine Accord should not be taken if the patient is taking antithyroid drugs (thyreostatics). If necessary, the doctor may adjust the dose. If the patient becomes pregnant, they should contact their doctor. There is no evidence that taking Levothyroxine Accord during breastfeeding harms the baby with normal thyroid function. Levothyroxine Accord should not be taken if the patient is breastfeeding and taking antithyroid drugs (thyreostatics).
Levothyroxine sodium should not affect the ability to drive and use machines.
This medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means it is considered "sodium-free". The 25 microgram tablet contains orange yellow S (E 110), which may cause allergic reactions. The 75 microgram tablet contains Allura red AC (E 129), which may cause allergic reactions. The 88 microgram tablet contains tartrazine (E 102), which may cause allergic reactions. The 100 microgram tablet contains tartrazine (E 102) and orange yellow S (E 110), which may cause allergic reactions. The 125 microgram tablet contains orange yellow S (E 110) and Allura red AC (E 129), which may cause allergic reactions.
This medicine should always be taken exactly as prescribed by the doctor or pharmacist. In case of doubts, the patient should consult their doctor or pharmacist. The doctor will determine the appropriate dose for each patient based on clinical assessment and laboratory tests. Treatment usually starts with a small dose, which is increased every 2 to 4 weeks until the full dose is reached, adjusted individually for each patient. In the first weeks of treatment, laboratory tests will be necessary to allow the doctor to adjust the appropriate dose. If a child is born with a thyroid disease characterized by insufficient production of thyroid hormones, it is essential to supplement them quickly. Therefore, the doctor may recommend a higher initial dose of 10 to 15 micrograms per kilogram of body weight per day for the first 3 months. Then, the doctor will adjust the dose individually. Typical dose ranges are presented in the table below. Smaller, individually adjusted doses may be sufficient for:
Administration of Levothyroxine Accord | Recommended daily dose of Levothyroxine Accord | |
Treatment of mild goiter in patients with normal thyroid function |
| |
Prevention of goiter recurrence after surgery |
| |
Supplementation of natural thyroid hormone deficiency when the thyroid gland does not produce enough hormones
| Adults
| Children and adolescents 12.5 – 50 micrograms
|
Inhibition of tumor growth in patients with thyroid cancer |
| |
Normalization of thyroid hormone levels during treatment of excessive thyroid hormone production with antithyroid drugs |
| |
Thyroid function tests | Levothyroxine Accord, 100 micrograms: Start 2 weeks before the test – 200 micrograms (2 tablets) Levothyroxine Accord, 150 micrograms: Start 4 weeks before the test – 75 micrograms (½ tablet) for 2 weeks, and then 150 micrograms (1 tablet) until the test Levothyroxine Accord, 200 micrograms: Start 2 weeks before the test – 200 micrograms (1 tablet) |
Method of administration
Levothyroxine Accord is intended for oral use. The single daily dose should be taken in the morning, on an empty stomach (at least half an hour before breakfast), preferably with a small amount of liquid, e.g., half a glass of water. Infants should be given the entire daily dose of Levothyroxine Accord once a day, at least half an hour before the first meal of the day. Immediately before administration, the tablet should be crushed and mixed with a small amount of water, and the resulting suspension, which should be prepared freshly each time, should be given with a small additional amount of liquid. Duration of treatment
The duration of treatment may vary depending on the reason for taking Levothyroxine Accord. The doctor will discuss with each patient how long they need to take the medicine. Most patients need to take Levothyroxine Accord for the rest of their lives.
In case of taking a higher dose than recommended, the following symptoms may occur: rapid heartbeat, restlessness, excitement, or involuntary movements. In patients with neurological disorders, such as epilepsy, single seizures have been observed. In patients with psychotic disorders, symptoms of acute psychosis may occur. In such cases, the patient should consult their doctor.
The patient should not take a double dose of the medicine to make up for a missed dose. The next day, they should take the usual dose of the medicine. In case of doubts about taking Levothyroxine Accord, the patient should consult their doctor or pharmacist.
Like all medicines, Levothyroxine Accord can cause side effects, although not everybody gets them. All medicines can cause allergic reactions, but severe allergic reactions are rare. If the patient experiences sudden symptoms such as wheezing, difficulty breathing, swelling of the eyelids, face, or lips, rash, and itching (especially all over the body), they should contact their doctor immediately. In case of poor tolerance to the prescribed dose or if the patient takes a higher dose of Levothyroxine Accord than recommended, symptoms similar to hyperthyroidism may occur, especially if the dose is increased too quickly at the beginning of treatment. The following side effects have been observed (frequency not known):
If the patient experiences any of the above symptoms, they should contact their doctor. The symptoms usually disappear after dose adjustment.
If the patient experiences any side effects, including any side effects not listed in this leaflet, they should tell their doctor, pharmacist, or nurse.
