Hello! Three weeks ago I started experiencing the effects of being overmedicated on levothyroxine: jitteriness, insomnia, racing heart, anxiety, unable to exercise, etc. I've been overmedicated before, so these sensations were familiar. After getting labs done, I discovered that my TSH was .5 and my FT4 was 1.9. (Last Oct. I was feeling good at TSH 1.8 and FT4 1.6.) My doctor reduced my dosage from 88 to 75mcg. For the first week (while waiting to get lab results), I either skipped a dose or took only half. Beginning the second week I began taking the new, reduced dosage (75). By the end of the second week, I was beginning to feel like myself again--heart rate down, sleeping (finally!), no panic attacks, etc. However, starting yesterday (week 3), my overmedication symptoms started to return. The random panic attacks are especially strong. Since the middle of January, I have lost about 8 lbs., and I think the stress of knowing I was overmedicated caused me to lose a bit more. So, my question is this. Could the return of "hyper" symptoms mean that the new dosage is still too high? I'm wondering this since I was feeling my best two weeks after skipping/taking half of my med. I've heard that some people stop taking their meds altogether for a week or two after realizing they were overmedicated, so I found it odd that my doctor only minorly reduced my dosage and told me to wait 6 weeks. Any advice would be appreciated!
