Uses of Eltroxin Tablets
Eltroxin is a hormone replacement medicine usually given to patients with hypothyroidism.
Levothyroxine Sodium (the active ingredient in Eltroxin Tablets) is also frequently used to treat goiter because it usually lowers the levels of thyroid-stimulating hormone (TSH), a hormone that is considered goitrogenic (goiter-inducing). Eltroxin is also prescribed for the management of cancerous thyroid nodules.
Eltroxin Tablets - Dosage
Eltroxin Tablets are taken on an empty stomach approximately half an hour to an hour before meals. Eltroxin tablets have to be swallowed whole, and taken with a full glass of water. The tablets should not be split.
For adult hypothyroidism the recommended starting dose of levothyroxine is 50 to 100 micrograms daily. The dose is adjusted at four or six week intervals by 25 mcg/day (or 50 micrograms/day) until attainment of clinical and biochemical euthyroidism. Starting doses and dose changes may differ with individual patients based upon age, the presence of cardiovascular disease, the development of tolerance (reduced effectiveness with continued use), side effects to the medication, and blood levels of thyroid hormone. It may take one to three weeks after initiating therapy with levothyroxine or changing the dose before effects are seen. The goal of replacement therapy is to maintain a normal blood thyroxine level. In case the dose of thyorxine is increased too quickly, symptoms such as diarrhoea, nervousness, rapid pulse, insomnia, tremors and sometimes anginal pain in cases where there is latent myocardial ischaemia may occur. In such situations the dosage must be reduced or stopped for a day or two, then restarted at a lower level.
Drug Class and Mechanism
Levothyroxine is a synthetic (man-made) version of the principal thyroid hormone, thyroxine (T4) that is made and released by the thyroid gland. Thyroid hormone increases the metabolic rate of cells of all tissues in the body. In the foetus and newborn, the thyroid hormone is important for the growth and development of all tissues including bones and the brain. In adults, the thyroid hormone helps to maintain brain function, food metabolism, and body temperature, among other effects.
Take the missed dose of Eltroxin as soon as you remember.
Storage Instructions for Eltroxin Tablets
Levothyroxine tablets should be kept at room temperature, 15-30°C (59-86°F) in a light-resistant, tight container. Keep away from children.
Warnings and Precautions when using Eltroxin Tablets
There are foods and other substances that can interfere with absorption of thyroxine replacement. Patients under treatment ought to avoid taking calcium and iron supplements within 4 hours, as well as soy products within 3 hours of the medication, as these can reduce absorption of the drug. Grapefruit juice may delay the absorption of levothyroxine, but it is not believed to have a significant effect on bioavailability. Other substances that reduce absorption are aluminium and magnesium containing antacids, simethicone or sucralfate,cholestyramine, colestipol, Kayexalate. Different substances cause other adverse effects that may be severe. Ketamine may cause hypertension and tachycardia and tricyclic and tetracyclic antidepressants increase its toxicity. On the other hand Lithium can cause hyperthyroidism (but most often hypothyroidism) by affecting iodine metabolism of the thyroid itself and thus inhibits synthetic levothyroxine as well.
Side Effects of Eltroxin Tablets
Eltroxin dosing must be carefully controlled to achieve TSH levels within the normal reference range. Long term suppression of TSH values below normal values will frequently cause cardiac side effects and contribute to decreases in bone mineral density (in contrast too high TSH levels are also well known to contribute to osteoporosis).
