Treatment of hyperprolactinemia varies greatly depending on the cause. For example, if the increase in the hormone prolactin is related to some type of drug, stopping this medication would restore ovulation and thus fertility.
Otherwise, medical treatment for about 6 months with dopamine agonists can restore menstrual cycles if there is no other associated factor.
Dopamine agonists are drugs that mimic dopamine and can bind to its neuronal receptors, allowing them to perform their function of inhibiting the production of prolactin in the pituitary gland.
Finally, when large prolactinomas are the cause of hyperprolactinemia, surgery may be used. However, surgery does not ensure that the prolactinoma will not reoccur and further treatment will be necessary.
