I'm 25 years old and undergoing medications for thyroid and pcod. NW I'm taking thyronorm 50 mg. T3 and t4 are n normal range but tsh s 13.4.prolactin is 40. My doctor don't prescribe tablets to lower prolactin level. She said due to increase in tsh level prolactin are elevated so it's not necessary to take tablets separately for this. My doubt is whether I need to take tablets to lower prolactin prob. I have started taking thyroid tablets for almost 28 days. When should I take blood test again to check my tsh level.
