Euthyrox Side Effects

If taken according to the directions and under the physician's supervision, side effects are not to be expected during treatment with Euthyrox. If the individual tolerance limit for levothyroxine is exceeded or in the case of overdosage, the known symptoms of hyperthyroidism may occur, especially if the dose is increased too quickly at the start of treatment. Such symptoms include finger tremor, palpitation (pounding of the heart), heart rhythm disturbances, excessive sweating, diarrhea, weight loss, sleeplessness or restlessness.
Consult the physician immediately if any side effects are observed, the patient will take any appropriate counter measures if necessary. If signs of hyperthyroidism is observed, the physician will recommend the patient to discontinue the medication if necessary, and will start on a lower dose again once the complaints have disappeared.
