May i know for what use this question is for? Anyhow, to answer your question, the dosage varies for different age groups, body weight and to the specific condition the patient has. Overdosing yourself will lead to palpitations, nausea, increased appetite, insomnia. I guess you can add more details about this question. And of course, if you're not in a hurry, please visit your local Endocrinologist so you will be provided with the right dosage and right meds. cheers!
