Question: I am currently taking a low dosage of Tapazole (about 10 mg) for hyperthyroidism. I was wondering how long it takes for medication to “kick in”, so to speak, and start raising my TSH levels back to normal?
Answer: This is probably something that your own doctor or endocrinologist could probably answer, but I will take a stab at this one in general terms. Please note that every individual is different and, by no means, should you take my answer as “medical advice”.
With that being said, generally Tapazole will start to raise your TSH levels about a week after you start taking it. It takes the medication that long to work itself into your system and alter the hormonal “synergy” of your endocrine system.
As for how much Tapazole will raise your TSH levels, that depends A LOT on your own body’s chemistry and how well your body receives the medication. I have seen TSH levels change as little as 0.5 points per month on your dosage… and I have also seen the 10 mg dosage raise TSH levels a whopping 2.0 points per month. As I said, it depends on your own body and is difficult to accurately predict.
