Scientific Name: levothyroxine sodium 

Drug Class: thyroid hormones 


Synthroid (levothyroxine) is an oral prescription drug indicated as replacement therapy for thyroidal, pituitary, and hypothalamic congenital or acquired hypothyroidism. It is also prescribed for pituitary thyrotropin suppression. It is given as an adjunct to surgery and radioiodine therapy to manage thyrotropin-dependent well-differentiated thyroid cancer. 

This is not indicated to suppress benign thyroid nodules and nontoxic diffuse goiter among iodine-sufficient patients. It is also not indicated to treat hypothyroidism in the recovery phase of subacute thyroiditis. 

Synthroid Dosage Forms 

This is available in Synthroid 0.025 mg, 0.15 mg, 0.075 mg, 0.088 mg, 0.100 mg, 0.112 mg, 0.125 mg, 0.137 mg, 0.175 mg, 0.200 mg, 0.300 mg tablets. 

Synthroid Mechanism of Action 

This hormone’s main action focuses on controlling DNA transcription and protein synthesis. This is a synthetically prepared levo-isomer of thyroxine or T4, which acts as a replacement. It is responsible for increasing the metabolic rate and decreasing thyroid-stimulating hormone production. 

How to Take Synthroid 

Before taking this medication, it is necessary to read the information leaflet or medication guide given by a healthcare professional. You must not take any medication unless you have understood all the information regarding it. Ask your doctor or pharmacist for further medical advice or additional details. 

The only way to take this pill is by mouth. This is usually prescribed once daily and should be taken on an empty stomach, not less than 30 minutes before breakfast. Swallow the tablet entirely. Cutting or crushing the medication is not recommended. Drink a full glass of water after. 

Make a dosing schedule. Do not increase/decrease your Synthroid dosage, and do not take it more frequently than prescribed. Taking too much Synthroid can result in adverse effects similar to hyperthyroidism.
