As with other ergot derivatives, pleuritis, exudative pleura disease, pleura fibrosis, lung fibrosis, and pericarditis are seen. These side effects are noted in less than 2% of ...
Hormone secreting pituitary adenomas cause one of several forms of hyperpituitarism.The specifics depend on the type of hormone. Some tumors secrete more than one hormone, the most common combination [8] being GH and prolactin, which present as Gigantism or Acromegaly and unexpected lactation (in both men and women).
Individuals with hyperprolactinemia may present with symptoms including galactorrhea, hypogonadism effects, and/or infertility. The magnitude that prolactin is elevated can be used as an indicator of the etiology of the hyperprolactinemia diagnosis. Prolactin levels over 250 ng/mL may suggest prolactinoma.
