An Introduction to Levoxyl Side Effects
As with any medicine, side effects are possible with
Levoxyl® (
levothyroxine sodium). However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well.
(This article covers many, but not all, of the possible side effects with Levoxyl. Your healthcare provider can discuss a more complete list of side effects with you.)
Possible Levoxyl Side Effects
Side effects typically occur when the
Levoxyl dosage is too high. Too much Levoxyl causes symptoms of an overactive thyroid (known medically as hyperthyroidism). These symptoms can be dangerous, and any of these symptoms should be reported to your healthcare provider (as they may signal that your Levoxyl dosage needs to be decreased). These side effects may include:
As with any medication, Levoxyl can also cause allergic reactions. Seek medical attention immediately if you develop signs of an allergic reaction, including:
- An unexplained rash
- Hives
- Itching
- Wheezing or difficulty breathing
- Unexplained swelling (especially of the lips, mouth, or throat).
