Some of the severe side effects of Levothyroxine are: mental or mood changes (eg, anxiety, irritability, nervousness); muscle weakness; seizures; severe or persistent headache or fatigue; shortness of breath; stomach cramps; tremors; trouble sleeping; wheezing. These side effects could cause dizziness, however you must seek medical advice at the soonest, hope this helps?

* difficulty breathing, wheezing, or shortness of breath
* chest pain

I hope this help, what other meds r u on? it´s because of the interactions.
