Levothyroxine Side Effects

levothyroxine tabletsLevothyroxine has been shown to cause serious side effects, such as:
  • dyspnea, or shortness or breath, that can signal respiratory side effects
  • tremor or muscle weakness
  • cardiovascular symptoms, such as palpitations, increased blood pressure or pulse, chest pain, and in rare cases heart attack and cardiac arrest
  • hair loss
  • flushing
  • decreased bone density
  • seizures
  • allergic reaction, which is characterized by rash, flushing, itching, swelling of the face, mouth, lips, or tongue, and difficulty breathing
Overdosage of  levothyroxine is often the culprit of most serious side effects, and it can also cause more serious complications such as shock, coma, cerebral embolism, or even death. If you experience any of these serious side effects, contact your doctor immediately. Levothyroxine may also cause common side effects, such as:
  • menstrual irregularities
  • difficulty getting pregnant
  • lastorm2

    If the disease process is Graves Disease (autoimmune disorder), with surgical removal of the thyroid gland leaving approx. 5%, is Levothyroxine the best hormone replacement?

      I would not use that. Go for the natual pork derivative. Less side effects and Levothyroxine is pushed on people because of the drug-rep kickbacks they recieve to push it on patients.

    Doctors do not like to prescribe the natural alternative to this drug because they don’t get the kickbacks as much. This is a dangerous drug and almost ruined my life. My hair is still very thin and I only used Levothyroxine for a few months and it has been several months stince I’ve been off of it. It has caused irreversable damage. DO NOT let your doctor just give you this. Ask questions and demand lists of alternatives. And I would advised against seeing a nurse practitioner for anything thyroid related. . Always see a real dotor.
