thanks for mposting your question -
if your prolactine level was so high - one should look for the cause.
The tablets will only reduce the output of prolactine levels - but not always deal with the cause.
Prolactine is a homrone which is produced by the pituary gland.
It can be high in : breast feading (which you are obviously not), if you have thyroid
if you are taking drops or tablets for your stomache , or if you are a number of other meidines esp. medicines such as anti-depressants or other psychiatric medicines.
It can also be high if you have a small benigne tumor
in the pituary gland. Go back and see your doctor and ask if they can check which would be the most likely cause of your high prolactine levels. Only if you have a benigne tumor shoudl you take the prescribed medication you have been taking in all other cases you have to deal with the cause and not just the symptom.
