Synthroid Overdose

As a result, a Synthroid overdose can occur if you take even a little more of your dosage than prescribed. Overdose symptoms can be dangerous and may include seizures, heart palpitations, and strokes. Treatment options for a Synthroid overdose may include pumping the stomach and supportive care.

Treatment for a Synthroid Overdose

The treatment for a Synthroid overdose will also vary. If the overdose was recent, the healthcare provider may administer certain medicines or place a tube into the stomach to "pump the stomach." Treatment also involves supportive care, which consists of treating the symptoms that occur as a result of the overdose. For example, supportive treatment options may include:

  • Medications to control seizures, arrhythmias, or other symptoms
  • Other treatments based on the complications that occur.
It is important that you seek medical attention immediately if you believe that you may have overdosed on Synthroid.
