Levothroid treats hypothyroidism, a condition that causes low thyroid function. By replacing the hormone normally produced by your thyroid, Levothroid increases your body's metabolism and energy levels. In some cases it's also used to prevent an enlarged thyroid gland, which is caused by a variety of conditions. While you may be aware of its efficacy you also need to be aware of Levothroid's side effects to make a sound decision regarding your treatment plan.
Most Likely to Occur
The most common side effects of Levothroid occur with higher doses, as stated by eMedTV.com. If your dose is too high you may begin suffering from an overactive thyroid. A simple adjustment in your medication may be all that is needed; however, in the meantime you may suffer from side effects such as feeling hot, fever, high blood pressure and bone fractures. These are due to Levothroid weakening your bones, making them more fragile. Muscle weakness may also occur, along with a fluctuation in your emotions. At times you may also feel shaky.
