Levoxyl Overdose

Because Levoxyl is a "narrow therapeutic index" medication, taking just a little too much of it can cause an overdose. The symptoms of a Levoxyl overdose can be very dangerous and may include things such as strokes, heart palpitations, and even a coma. Treatment options for a Levoxyl overdose may include pumping the stomach and providing supportive care.

Levoxyl Overdose: An Introduction

Levoxyl® (levothyroxine sodium) is a synthetic version of a naturally occurring thyroid hormone. Taking too much Levoxyl can result in hyperthyroidism, a condition that can be quite dangerous. The specific effects of a Levoxyl overdose will vary depending on a number of factors, including the Levoxyl dosage and whether it was taken with any other substances.
 

Symptoms of a Levoxyl Overdose

The symptoms of a Levoxyl overdose can be very dangerous. Some of the most dangerous symptoms include:
 
Levoxyl is a "narrow therapeutic index" drug, which means that the safe and effective dose is usually very close to the toxic dose. Therefore, a Levoxyl overdose can result from taking just a little too much Levoxyl.
 

Treatment for a Levoxyl Overdose

The treatment for a Levoxyl 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:
 
  • Fluids through an intravenous line (IV), if necessary
  • Medications to control arrhythmias, seizures, 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 Levoxyl.
