It is used to replace the thyroid hormone deficiency in an underactive thyroid, and comes in different strengths including 100 mcg to suit individual doses.<\/p>\n<hr \/>\n<h2 id=\"uses\"><span class=\"ez-toc-section\" id=\"Uses_of_Euthyrox\"><\/span>Uses of Euthyrox<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Euthyrox levothyroxine<\/strong> is prescribed to treat an underactive thyroid, after total or partial thyroid removal, to suppress goiter, and within follow-up of some thyroid-cancer cases. Determining use and dose is done by a doctor based on tests.<\/p>\n<hr \/>\n<h2 id=\"dose\"><span class=\"ez-toc-section\" id=\"Dosage_and_how_to_use_it\"><\/span>Dosage and how to use it<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The dose is individual, set by the doctor starting from a low dose then adjusted based on TSH. It is taken in the morning on an empty stomach 30\u201360 minutes before breakfast with water, and taking it at the same time daily is essential. Do not double the dose if you miss one.<\/p>\n<hr \/>\n<h2 id=\"duration\"><span class=\"ez-toc-section\" id=\"Expected_time_to_improvement\"><\/span>Expected time to improvement<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Symptoms improve gradually over weeks, but setting the ideal dose may take months of follow-up.
