Levothyroxine and insomnia help
Once synthroid dosage is properly calibrated, severity and/or occurrence of side effects usually subside. Understand that the severity and number of side effects you experience will be subject to individual variation and dose-dependent. Synthroid (Levothyroxine) Side Effects & Adverse Reactions (List)īelow is a list of side effects and adverse reactions associated with synthroid. Many synthroid users complain of unwanted adverse reactions that may be unavoidable. Despite the proven therapeutic efficacy of synthroid for the treatment of thyroid-related conditions, it isn’t devoid of side effects. In addition to treating hypothyroidism, synthroid is commonly prescribed to lower thyroid-stimulating hormone (TSH), thereby: preventing recurrent bouts of thyroid cancer, inhibiting growth of goiters, and managing nodular thyroid disease (lumps on the thyroid gland). This yields favorable metabolic effects via modulation of DNA transcription and protein synthesis. Sometimes referred to as L-thyroxine, synthroid functions by mimicking the effects of the endogenous hormone thyroxine (T4) manufactured by the thyroid glands. The World Health Organization regards synthroid as an “essential medicine” or among the most important pharmaceuticals necessary in a basic health system. As a pharmaceutical, synthroid is among the most prescribed medications in the United States, with upwards of 20 million prescriptions filled for the drug annually.
It was initially synthesized by British chemists Charles Robert Harington and George Barger in 1927. Synthroid (Levothyroxine) is a synthetic thyroid (T4) hormone commonly administered to treat hypothyroidism (or thyroid deficiency).
