Synthroid (Levothyroxine), which is used for treating sluggish thyroids or hypothyroidism as well as for weight loss and muscle growth,is usually taken once a day about an hour before the breakfast. But new studies raise the questionon Synthroid dosage: whether it’s better to use the medication weekly or daily.

Research made in Park Hospital ofGuragaon, India, in 2016 suggests that weekly doses of Synthroid work as well. The study involved 40 women with hypothyroidism, who took a weekly dose of Synthroid (seven times their daily dose) for six months.

Synthroid dosage: weekly or daily?

American endocrinologists still prefer daily dosing. Jacqueline Jonklaas from Georgetown University Medical Center, Washington, D.C., says that daily therapy is preferable because there are minimal ups and downs in the blood level.

"If you give a larger dose on a weekly basis there are big peaks and troughs, - she explains. - This means that a patient may have symptoms of too much thyroid hormone right after the dose is given and symptoms of too little right before the next dose is due to be given".

According to the expert, only those who could not be kept with normal thyroid levels on daily therapy might take weekly dosages.

Older people should reduce the dose to not more than 1 mcg/kg/day. Usually it’s recommended for them to start with 25-50 mcg/day gradually increasing the dose.

Common usage is half an hour – one hour before breakfast and at least four hours apart from other drugs that could interfere it’s absorption or affect it somehow.
