I had a test done and the Dr. said my thyroid was too low and said I had to go up to 0.25. Is this a lower dose or a higher dose? Would it be due to high T4 levels or low T3 levels? I am confused. I've been steadly going up to the next dose each time I test. I've been at .175 for about 5 to 6 months. en-us Copyright 2009 Prescription Drug Info All Rights Reserved. 11/22/2009 3:01:30 AM 20 http://www.PrescriptionDrug-Info.com/threads/Drug-Strength-D76722_s2.htm#180745 Yes, 0.25 is a higher dose than 0.175. As to which levels your doctor is referring to, I have no idea, you would really need to ask them. <br> <br>It is normal to try a certain dosage for several months and then make adjustments as needed, this is done with virtually any kind of medication. <br> <br>Have you asked your doctor your questions?
