However, presence of a pituitary macroadenoma may require surgical or radiological management. Best way is to give it is as continuous therapy and prolactin levels reduce in about a week; ovulation and menstruation resumes in weeks.

Shimatsu A, Hattori N. Amenorre agonists have been in clinical use for many years and remain the cornerstone for therapy of prolactinomas. Scanning should be repeated only if symptoms reappear or exacerbate. Even one normal value should be considered as normal and an isolated raised one should be discarded as spurious. Hyperprolactinemia without an identified cause requires imaging of the hypothalamic-pituitary area.
Prolactin levels should be repeated after 4 weeks of starting therapy and then repeated only hiperpeolactinemia months depending on symptom reversal. Raised prolactin levels can also be caused by pituitary adenomas cosecreting prolactin hormone.
Hyperprolactinemia can be physiological or pathological. This may explain many cases of very high prolactin levels sometimes found uiperprolactinemia normally ovulating women and do not require any treatment. It is worth noting that many premenopausal women with hyperprolactinemia do not have galactorrhea, and many with galactorrhea do not have hyperprolactinemia. Do the limits of serum prolactin in disconnection hyperprolactinaemia need re-definition?
Ben-Jonathan N, Hnasko R. Once physiological causes such as pregnancy, systemic disorders such as primary hypothyroidism and the use of drugs with dopamine antagonistic actions such as metochlopramide have been ruled out, the most common cause of hyperprolactinemia is a PRL-secreting pituitary adenoma or prolactinoma.
Many commercial assays do not detect macroprolactin. Other prolactin inhibiting factors include gamma amino butyric acid GABAsomatostatin, acetylcholine, and norepinephrine. Complete resection is difficult because prolactin producing tumor looks like the surrounding normal pituitary.
It is of very limited benefit in the treatment of these tumors since the response is typically quite modest and delayed. Please enter Password Forgot Username? Long-term management of prolactinomas. Unless the prolactin levels are markedly elevated, the investigation should be repeated before labeling the patient as hyperprolactinemic.
