Prolactinoma

Women with prolactinomas should be instructed that dopamine agonist treatment may restore ovulation and fertility within a very short time, thus contraception should be used to prevent unplanned pregnancy.

Patients with large macroprolactinomas must be warned about symptoms suggesting acute apoplexy (severe headache, vomiting, visual impairment, ocular palsy due to acute haemorrhagic or ischaemic infarction of the adenoma) while treated medically. Apoplexy may require urgent trans-sphenoidal pituitary decompression.
