The Most Frequent Questions about Synthroid Answered


Synthroid and weight loss

Weight loss is a common effect of hormonal therapy with Synthroid, as an underactive thyroid usually leads to what is commonly called a slow metabolism and thus to weight gain. It is for that reason that some people who don’t suffer from any thyroid problems start taking levothyroxine in hopes of stimulating their metabolism and losing weight.

Taking unnecessary hormones can cause a hormonal imbalance which comes with numerous health risks including that of cardiovascular disease, so it’s not recommended to take Synthroid purely for weight loss unless the patient actually has a preexisting thyroid condition.

Synthroid/Levothyroxine price

The price may vary in a wide range depending on the region. Synthroid prices usually start at around $25 for a pack of 30 tablets. This is consistent for most dosages. 90 tablet boxes, however, can get as expensive as $60.

Prices for generic levothyroxine, however, can be much lower, around $15 for a 30 tablet pack.

How long does it take for Synthroid to work?

Levothyroxine prescriptions will vary depending on the patient’s age, build and the severity of their condition, so the period that will pass before it starts to fully work will also vary in each case. Patients can experience severe side-effects at first, before it reaches its peak effect, but those should start easing until the supplement really kicks in, at about 4 to 8 weeks into treatment.

Does Synthroid cause weight gain?

No. In theory, an underactive thyroid should lead to weight gain, which means that if hypothyroidism is corrected with hormonal therapy like taking Synthroid, for instance, the patient should be losing instead of gaining weight.

However, in some rare cases levothyroxine users report weight gain. The cause of this phenomenon is yet unknown, but some theories suggest that just a wrong diagnosis or prescription could be behind it.

Generic name for Synthroid

The generic name of Synthroid is Levothyroxine. Other brand names for the drug include Levothroid, Levoxyl, Tirosint, Unithroid and Levo-T.

How to take Synthroid

Patients are often told to take Synthroid first thing in the morning, or at least 30 minutes before their first meal, as food – and some foods in particular, like soybeans, diet fibers, papaya or grapefruit – can inhibit the absorption of this medicine and thus keep the adequate level of thyroid hormone from getting to the bloodstream. To solve this problem, some people take this medication before going to bed, which is usually a few hours or more after they ate their last meal of the day. Users should also take Synthroid at least 4 hours before any other medications because they could interact with the drug.

What is levothyroxine sodium?

Levothyroxine sodium or Synthroid is a thyroid medication, which is used to treat several thyroid-related conditions. It acts as a hormonal replacement for the thyroid hormone, which is usually produced by the thyroid gland and is responsible for regulating the metabolism and energy levels. The medicine is more commonly prescribed for hypothyroidism – a low thyroid hormone or a less active thyroid – but it can also be used to treat goiters – an engorged thyroid gland – or even thyroid cancer.

Synthroid and coffee

Drinking coffee right before or after taking levothyroxine doesn’t have any obvious, externally noticeable side effects. However, the two do interact in a negative way. Studies reveal that consuming coffee within 60 minutes after taking Synthroid reduces the level of absorption of the hormone by at least 25%, which is a percentage to be reckoned with. High levels of cortisol, which can also be associated with regular coffee consumption, also hinder the production and absorption of the hormone, further worsening patients’ chances of getting effective treatment from the drug.

What happens if I stop taking levothyroxine?

Hormonal replacement therapy treatments like what is done with levothyroxine are usually meant to be followed for life, so stopping or discontinuing the treatment without medical guidance is strongly unadvisable. Stopping the treatment will create a hormonal imbalance similar or worse than the preexisting one which led the patient to take this supplement. The severity of the physical manifestations of this imbalance will depend on the severity of the patient’s preexisting condition, the dosage that had been administrated and how long the treatment had been administered for.
