Now i increased my dosage to 200mg of thyroxine. will it be sufficient to improve my level orelse am i required to do something else.

Thyroid: It depends. You need to wait a bit and then have your levels rechecked. Your doctor will adjust the dose accordingly. If your TSH is still high at that point, then you might need a referral to an endocrinologist. Ive seen people react differently to generic levothyroxine vs synthroid more than any other med so that might be something they'll consider.
