I had RAI treatment back in early June and my thyroid finally changed to hypo and started to die towards the end of October. I was originally told that it would take 4 to 6 weeks to see results. That’s a much longer wait than 6 weeks.
As a result of officially being hypothyroidism now, I have now started taking Levothyroxine on a once-daily schedule.
It’s important to understand that Levothyroxine takes 4-6 weeks to build up in your system and do its job, which is why you should have your levels checked again after that period of time. My endocrinologist asked that I have my blood tested after 4 weeks and see her the following week. She explained that until we found the correct dosage for my body, we would be seeing each other every 4 to 6 weeks to get my blood tested and see how I’m doing.
So keep in mind that your body needs to get used to this sudden hormone replacement. You should give it a least a few days to settle down before asking for a dosage adjustment.
My prescription was quite precise to take the pill in the morning and wait 30 minutes before eating and to wait 4 hours in the case of iron or calcium.
What my endocrinologist and my pharmacist both failed to advise me about is that the combination of levothyroxine and antidepressants increase its toxicity. I changed the times that I take my pills to make sure they are 2 hours apart. The good thing is I now understand why I’ve been feeling off. The bad thing is it looks like I’m going back through the new medication adjustment period. I look like an exhausted blowfish this morning and had to remove my wedding ring. I hate being a newlywed and not wearing my rings. Fun! (heavy on the sarcasm).
I’ve had my first blood test results after being put on Synthroid. My results were better, but I am still in hypo. My endocrinologist adjusted my prescription for a higher dose.
I have to keep in mind that ever after my thyroid labs are within range it will take time for my body to return to a healthy state. My body will need time to adjust from functioning in hyper speed to hypo to normal speed.
