Levothyroxine is an effective medication, used to treat hypothyroidism (underactive thyroid). The thyroid gland produces hormones to control growth and energy levels, but those with an underactive thyroid do not produce the necessary amount. Levothyroxine is used to replenish this.


What is Levothyroxine?


Levothyroxine is a medication that is used to treat hypothyroidism, which is also known as an underactive thyroid. The generic name is levothyroxine but its brand names include Levoxyl, Synthroid, Euthyrox, Tirosint, Unithroid and Tirosint-Sol. Having an underactive thyroid means that your body is not given the necessary hormones it needs to regulate metabolism and energy. To solve this problem, Levothyroxine provides the hormones that is normally produced by the thyroid gland. Other uses for this medication include treating and prevent goiter, which can be caused by a number of factors such as cancer, surgery, radiation treatment and hormone imbalances. 


What is hypothyroidism? 


Hypothyroidism refers to an underactive thyroid gland, which means that it doesn’t produce enough thyroid hormone that the body needs. This is usually caused by autoimmune diseases like Hashimoto’s thyroiditis, radiation treatment and surgical removal of the thyroid. When your body starts lacking in thyroid hormones, it can be difficult for it to function normally. 


For people suffering from hypothyroidism, they can experience being colder, getting tired more easily, their skin getting drier and them feeling more constipated. The symptoms for hypothyroidism might be easily confused with other diseases or conditions. The best way to determine if you have this condition or not is to subject yourself to a blood test for TSH. If you have other family members that suffer from thyroid disease, then you should get yourself checked as thyroid diseases can run in the family. 


How does Levothyroxine work?


Levothyroxine replenishes your body of the thyroxine hormone that is normally produced by the thyroid gland. If the thyroid gland cannot, for some reason, function as well as it used to, then Levothyroxine is a good alternative in ensuring that your body can still function well. This medication boosts thyroxine hormone levels.


What should you know before taking Levothyroxine? 


Not everybody is suited for Levothyroxine. When people misuse this medication, then it can be extremely dangerous as certain side-effects, even death, can happen to them. This shouldn’t be used to treat weight problems or obesity.

  • A thyroid disorder called thyrotoxicosis 
  • An untreated or uncontrolled adrenal gland disorder 
  • Symptoms of a heart attack, which includes pain spreading to the jaw or shoulder, nausea, a general ill feeling, swearing or pain the chest

It can be extremely harmful for you and the baby if thyroid hormone levels are suddenly changed. In this case, your doctor may give you a different dosage. This is the same if you are currently breastfeeding. Abrupt changes in your thyroxine hormone can be detrimental for you and your baby’s health.
