Side Effects of Levothyroxine

The side effects of Levothyroxine differ from individual to individual. That does not mean that you stop taking the medication entirely especially if you happen to suffer from abnormal thyroid function like hypothyroidism. However, some people still make the mistake of skipping on their meds just because they are afraid of possible side effects.


The Thyroid

In general, the thyroid is a small pear shaped gland that is responsible for secreting hormones which in turn regulate your metabolism. The hormones are also responsible for regulating your body temperature, heart rate and energy levels.

Some of the very common excuses most patients give are –

  • Why should I take more when I don’t feel any better with it?
  • Prescription medication scares me.
  • My health was perfectly fine before I started taking my meds. The side effects are not making it worth my while.
  • Natural remedies are safer.
  • I forget when I am supposed to take it every day. It’s a bother having to double my dosage just to keep up.
  • It makes me feel worse.


Levothyroxine is just one of the drugs that are used to combat thyroid related medical issues. Other like thyroid dysfunctions that warrant specific medication are –

This condition indicates an over active thyroid. It can be caused due to an overproduction of the thyroid hormone by the thyroid gland or by their excessive intake of drugs that trigger overproduction.



This condition indicates an under active thyroid. Like the name implies, it happens when the thyroid gland does not secrete as much hormones as are needed to keep the body’s metabolism in check. The effects are felt throughout the whole body due to which it eventually stops to function as efficiently. The condition usually occurs in adults but children are also known to develop it on some occasions. For example, congenital hypothyroidism is a thyroid related condition that is present from birth.


 A more serious form of the condition is Myxedema or advanced hypothyroidism. The condition is an unfortunate product in patients with long term undiagnosed hypothyroidism. According to research, women are more likely to develop the condition as compared to men.


All of these are counteracted with conventional thyroid medication. However the same drugs also happen to involve radioactive iodine treatment, synthetic hormones as well as others. Needless to say, such treatments do have a propensity to end up in serious side effects which means that patients have to be monitored on a regular basis.


The symptoms related to thyroid dysfunctions themselves are almost negligee and might also imitate other diseases. The side effects of the medications that are used to treat them, however, can be more serious. This is also why it is important for patients to determine whether their poor health is due to thyroid malfunction or something else. The side effects of Levothyroxine as well as other thyroid medication can become fatal if you are not careful on how you use them.
