What are the major side effects of bromocriptine or cabergoline?
Both drugs may cause nausea, dizziness, and low blood pressure. The side effects can be lessened by starting therapy at a low dose and by taking the pills at bedtime and with food.
What happens if I stop the bromocriptine or cabergoline?
Prolactin levels will increase and the tumor will resume its original size.
Is a prolactinoma the same as a brain tumor?
No, prolactinomas are benign pituitary tumors that are not cancerous or malignant. The pituitary gland is below the brain and not part of it.
Is it necessary to continue bromocriptine or cabergoline during pregnancy?
No, small tumors rarely increase in size during pregnancy so there is no reason to continue either drug once pregnancy is confirmed. It is normal for the pituitary gland to increase in size during pregnancy, but this typically causes no problems.
How long will I have to take bromocriptine or cabergoline?
There is no definitive answer to this question. If you have a microadenoma, your doctor may recommend stopping or tapering the drug after 2 years of therapy. If you have a macroadenoma, long-term therapy is recommended and treatment will likely be life-long.
Can I take a birth control pill if I am taking cabergoline or bromocriptine?
If I have a prolactinoma, will I be able to have children?
