[57], The serum concentration of prolactin can be given in mass concentration (g/L or ng/mL), molar concentration (nmol/L or pmol/L), or international units (typically mIU/L). As for the use of aripiprazole in combination with other antipsychotics, large clinical trials are needed. Baumgartner A, Graf KJ, Kurten I. Prolactin in patients with major depressive disorder and in healthy subjects. Most symptoms of hyperprolactinemia involve the reproductive system and are due to both a direct action of prolactin on target tissues and indirect effects mediated by the decrease in gonadotropin pulsatile secretion, that leads to gonadal dysfunction. Since prolactin levels affect milk production and menstrual cycles, it can be difficult to detect in men. Melkersson reported the following prevalence of treatment-induced hyperprolactinemia in 75 patients: risperidone (medium daily dosage 3 mg/day) 89%, olanzapine (medium daily dosage 10 mg/day) 24% and clozapine (medium daily dosage 400 mg/day) 0%. Effects of carbamazepine on prolactin secretion in normal subjects and in epileptic subjects. Longitudinal study of basal prolactin and post-TRH-stimulated prolactin levels. Hypoprolactinemia can result from hypopituitarism, excessive dopaminergic action in the tuberoinfundibular pathway and ingestion of D2 receptor agonists such as bromocriptine. [61][62] Previous standards relied on prolactin from animal sources. Whether you want to breastfeed exclusively or just more often, there are many ways to increase your breast milk supply. [11], It has been shown in rats and sheep that prolactin affects lipid synthesis differentially in mammary and adipose cells. Bromocriptine is taken 2-3 times a day and cabergoline is long acting and used once or twice a week. Among subjects treated for 28 days, milk prolactin levels decreased to The so-called typical antipsychotics are frequently responsible for drug-related hyperprolactinemia. II. (Paparrigopoulos et al 2006). Clonazepam (a central type benzodiazepine agonist) and diazepam (a mixed agonist) are reported to decrease prolactin levels, possibly through a direct action on the anterior pituitary gland (Jarvinen et al 1992) (Figure 2). A case report confirmed the successful strategy of switching to olanzapine while tapering risperidone: one month of titrated dose (15 mg) olanzapine normalized serum prolactin, restored menstrual regularity, resolved galactorrhea and improved the psychiatric condition (Canuso et al 1998). If this is the case, you can stimulate your breasts to build your breast milk supply by using a breast pump. Prolactin lowering and-releasing drugs. However, in 60 postmenopausal women receiving replacement therapy with estrogen plus anti-androgen cyproterone acetate, a significant increase in hyperprolactinemic response to dopaminergic drug sulpiride was observed (Paoletti et al 2001), though normal basal prolactin levels were confirmed. Accelerating Breakthroughs & Improving Care, Vaginal dryness, leading to pain during intercourse, Problems with menstruationhaving no periods or irregular periods, Production of breast milk when not pregnant or nursing, Erectile dysfunctiontrouble getting or keeping an erection, Mental health disorders (antipsychotics such as Risperdal and Haloperidol), High blood pressure (calcium-channel blockers and methyldopa), Depression (tricyclic and SSRI antidepressants), Chest-wall injuries or other conditions that affect the chest wall, such as shingles. It's essential for you to take care of yourself. At clinical doses, atypical neuroleptics occupy serotoninergic receptors near to saturation, but show considerable differences on D2 receptor occupancies, with clozapine showing the lowest degree of occupation, as confirmed by blunted prolactin responses to the acute administration of the dopaminergic drug haloperidol after olanzapine but not after clozapine administration (Markianos et al 2002). Medicines work well for most people with prolactinomas and are well tolerated. Little is known, however, about dose-dependency of estrogen effects on plasma hormone levels. Discontinuation of the bromocriptine treatment and increase in antipsychotic dosage resulted in complete remission. Our physician referral directory is comprised of over 6,500 members of the Society. Bromocriptine is taken 2-3 times a day and cabergoline is long acting and used once or twice a week. Int Breastfeed J. Tollin (Tollin 2000) reported 4 patients on risperidone, with significant hyperprolactinemia (65.5 to 209 ng/ml) that showed reduction of prolactin level and alleviated hypogonadism after dopamine agonists (bromocriptine or cabergoline) were added, without deterioration of psychotic symptoms. In that study (Paparrigopoulos et al 2006), mean prolactin increase was significantly greater in women than in men. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Levi-Minzi S, Bermanzohn PC, Siris SG. However, Schlienger et al showed that basal plasma levels of prolactin and delta prolactin response to TRH were increased in women on clomipramine but remained normal under maprotiline, in agreement with the different pharmacologic effect of these two classes of drugs, tricyclics mainly inhibiting serotonin, while tetracyclics rather norepinephrine recaptation (Schlienger et al 1980). This prolactin raising effect, that amoxapine shares with loxapine, a related compound widely used as neuroleptic (Robertson et al 1982), is reported in both female and male patients and may be explained with the blockade of dopamine receptors in central tuberoinfundibular pathways (Cooper et al 1981) or in the anterior pituitary gland (Robertson et al 1982) (Figure 2). Paoletti AM, Floris S, Mannias M, et al. This condition, referred to as macroprolactinemia, is characterized by normal levels of biological prolactin and lack of clinical symptoms (Gibney et al 2005). Opioids and the pulsatile prolactin secretory pattern: effects of hyperprolactinemia. This website is using a security service to protect itself from online attacks. Breast enlargement during chronic antidepressant therapy. David SR, Taylor CC, Kinon BJ, et al. 139.162.236.219 In the same study by Kearns et al, prolactin increase under risperidone was present in 12 out of 12 patients and was influenced by age and gender (but not by duration of the therapy), being higher in young females. Other antipsychotics, such as olanzapine, ziprasidone and clozapine, have been associated with attenuated dopamine-induced ERK phosphorylation (Bruins et al 2006). Mental health, attachment and breastfeeding: Implications for adopted children and their mothers. The abolishment of prolactin response to clomipramine after pre-treatment with serotonin receptor blockers clozapine and olanzapine (Markianos et al 2002) and its enhancement after L-tryptophan (Anderson and Cowen 1986) confirm the involvement of serotoninergic pathway in clomipramine-induced prolactin increase. So, how do prolactin and breastfeeding relate to one another? Bromocriptine for negative schizophrenia. The majority of breastfeeding mothers, however, already know that our bodies produce the most milk at night and in the morning. It has important cell cycle-related functions as a growth-, differentiating- and anti-apoptotic factor. The antihypertensive beta-blocker labetalol has been described to increase prolactin levels when administered intravenously in hypertensive patients, but not when administered orally (100 or 200 mg). Fairley KF, Barrie JU, Johnson W. Sterility and testicular atrophy related to cyclophosphamide therapy. It allows your child to breastfeed and stimulate your milk supply while getting the nutrition they need. A significant decrease in prolactin levels has been reported in patients treated with flutamide alone (Akaza et al 1993) or with flutamide and an oral contraceptive formulation with ethinyl estradiol and cyproterone acetate (Taner et al 2002). Cholinomimetic drugs with central effect, such as physostigmine, have been differently reported either to have no effect, to increase, or to inhibit prolactin release, though physostigmine may produce significant increases in plasma prolactin concentrations in humans after intravenous infusion. Correlated cholinomimetic-stimulated beta-endorphin and prolactin release in humans. Your Some end up breastfeeding less often or weaning earlier than they would likesometimes by choice, sometimes not. Newman ME, Shapira B, Lerer B. The effect of traditional tricyclic antidepressant imipramine on serum prolactin levels is controversial: oral administration of 100 mg, but not of 40 mg, led to consistent rise in prolactin levels, as measured in nine healthy young men, the effect being the result of serotonin enhancement following reuptake inhibition (Nutt et al 1987). Studies on both animals and humans demonstrated that endogenous opioids administered either intravenously or intraventricularly led to a rapid and dose-dependent plasma prolactin increase (Van Vugt and Meites 1980; Risch et al 1982). [68][69][70] However, different assays and methods for measuring prolactin are employed by different laboratories and as such the serum reference range for prolactin is often determined by the laboratory performing the measurement. Surgery: Surgery is usually done through the nose, to remove a tumor. Shin SH, Obonsawin MC, Van Vugt DA, et al. The hormone that causes breast milk production to be produced is called prolactin. The effects of lithium on prolactin secretion are controversial. Atypical antipsychotics are characterized by increased antipsychotic efficacy and fewer neurological and endocrine-related side effects as compared to classical antipsychotic drugs. Veldhuis JD, Borges JL, Drake CR, et al. Regarding age, data from studies performed with new atypical drugs in elderly patients and in youths are consistent with previous findings in adult patients: olanzapine appears to be a prolactin-sparing antipsychotic medication in the elderly (Kinon et al 2003c), and quetiapine produced significantly less frequent hyperprolactinemic events and lower mean elevation of prolactin levels than the conventional drug risperidone in children (Stevens et al 2005). Levels can rise after exercise, high-protein meals, minor surgical procedures,[45] following epileptic seizures[46] or due to physical or emotional stress. In some of these studies, no correlation was found between the dosage of estrogenic component of the combined oral contraceptives, or duration of their use, and prolactin levels (Reyniak et al 1980; Davis et al 1984). Slater SL, Lipper S, Shilling DJ, et al. government site. Arch Dis Child Fetal Neonatal Ed. Prolactin levels stay rather high for the first six months after giving birth while you are breastfeeding, unless youve had your first period since the baby, in which case they fall (As a result, some women experience a temporary decrease in milk supply during their period). Some of them, such as the tertiary amines imipramine (Nutt et al 1987), amitriptyline (Schlienger et al 1980) and clomipramine (Anderson and Cowen 1986) and the secondary amine desipramine (Price et al 1989), are thought to share a serotoninergic mechanism with SSRI. A recent study reported the rapid and complete reversibility of amisulpride-induced prolactin elevation in 17 psychiatric patients, with significant reduction after 14 to 51 days after discontinuation, independently from dosage (50800 mg/day) or treatment duration. Responsiveness to cAMP is mediated by an imperfect cAMPresponsive element and two CAAT/enhancer binding proteins (C/EBP). Amoxapine elevates serum prolactin in depressed men. A double-blind cross-over study. Symptoms of High Prolactin Levels - Verywell Health Pollock A, Mc Laren EH. Prolactin promotes neurogenesis in maternal and fetal brains. Prolactin levels may be checked as part of a sex hormone workup, as elevated prolactin secretion can suppress the secretion of follicle stimulating hormone and gonadotropin-releasing hormone, leading to hypogonadism and sometimes causing erectile dysfunction. After suspension of the oral treatment, prolactin returns to normal range within two to three weeks, depending on the half-life of the drug and its metabolites and on the storage in the fatty tissue, but remains above pre-treatment values for six months after discontinuation in case of intramuscular depot administration (Wieck and Haddad 2002). Accordingly, only monitoring of prolactin levels within the first 24 hours after oral administration of atypical antipsychotics may reveal early modifications: prolactin serum concentration increases within the first six hours after drug administration (up to two-fold from basal level) with a variable mean peak time, also in relation to the specific drug (120 min for risperidone, 180 min for clozapine and 290 min for olanzapine), and return to baseline values within 1224 hours. The neurobehavioral syndrome, that appears with the withdrawal of H2 receptors blockers and subsides with the restoration of the treatment or with the administration of a potent prolactin inducing drug as domperidone, should be related to a prompt reduction of prolactin levels (Rampello et al 1997). Influence of endogenous opiates on anterior pituitary function. Quetiapine interacts with a wide range of neurotransmitter receptors and has a high affinity for serotonin 5HT2A receptors and lower affinity for dopamine D2 receptors. Prolactinoma - NIDDK Prolactin is sometimes classified as a gonadotropin[16] although in humans it has only a weak luteotropic effect while the effect of suppressing classical gonadotropic hormones is more important. Atmaca M, Kuloglu M, Tezcan E, et al. Antipsychotics are the most common cause of pharmacologic hyperprolactinemia, and the majority of antipsychotic agents cause hyperprolactinemia (Molitch 2005). Benker G, Jaspers C, Hausler G, et al. Spitzer M, Sajjad R, Benjamin F. Pattern of development of hyperprolactinemia after initiation of haloperidol therapy. Laine K, Anttila M, Heinonen E, et al. 2006;1(1):5. doi:10.1186/1746-4358-1-5. The sucking action also aids in increasing milk supply, though care must be taken to ensure a good latch as incorrect latching will not propel milk or formula through the tube. These signals are carried by nerve fibers through the spinal cord to the hypothalamus, where changes in the electrical activity of neurons that regulate the pituitary gland increase prolactin secretion. "Thyroid Cancer | Endocrine Society." Zotepine is another drug reported to cause prolactin elevation during both acute and chronic administration (Von Bardeleben et al 1987). The hypothesis of a transient blockade of D2 receptors has been supported by PET scans showing that haloperidol constantly binds to D2 for 24 hours, while receptors occupation by atypical drugs is significantly shorter and mostly expired at the 24th hour (Seeman 2002), supporting the hypothesis of a transient D2 blockade. Prolactin levels in schizophrenic patients receiving perospirone in comparison to risperidone. In the study by Luciano et al, hyperprolactinemia, assessed by multiple blood sampling, appeared transient and resolved spontaneously in about 50% of cases (Luciano et al 1985). A study published in 1996 on 449 men receiving verapamil showed significantly higher prevalence of hyperprolactinemia in the treated group than in the control group (8.5% vs 3%); serum prolactin levels returned to normal in all patients that discontinued the therapy, while 93.3% of patients still on verapamil had persistent hyperprolactinemia, thus confirming the causal role of verapamil treatment in the development of hyperprolactinemia (Romeo et al 1996). Macroprolactin does not cause any health problems. Hyperprolactinemia is the most frequent abnormality of the anterior pituitary tumors, termed prolactinomas. However, the effect on prolactin levels is unlikely related to 5HT2 receptors binding, which would result in inhibition of prolactin secretion. Higher levels of prolactin are associated with an increase in milk production and a greater supply of breast milk. Hyperprolactinemia complicating juvenile granulosa cell tumor of the ovary. Breastfeed More. [47][48] In a study on female volunteers under hypnosis, prolactin surges resulted from the evocation, with rage, of humiliating experiences, but not from the fantasy of nursing.

Neuropsychological change in early phase schizophrenia during 12 months of treatment with olanzapine, risperidone or haloperidol. Kinon BJ, Basson BR, Gilmore JA, et al. This drug is used for the treatment of schizofrenia, bipolar disturb, acute mania, dementia, Tourette syndrome and autism. However, the safety and efficacy of the combined use of aripiprazole with other antipsychotics, for the treatment of drug-induced hyperprolactinemia, need to be demonstrated in large, controlled trials (Cassano et al 2007). Among antypsychotic, classical drugs, and more specifically haloperidol, chlorpromazine, thioridazine and thiothixene, induce sustained hyperprolactinemia. In conclusion, dopamine agonist therapy is not generally advisable (Miller 2004), even though successful cases are reported of risperidone-induced hyperprolactinemia treated with the addition of either cabergoline or bromocriptine, without worsening psychotic symptoms (Tollin 2000). [6][7], Discovered in non-human animals around 1930 by Oscar Riddle[8] and confirmed in humans in 1970 by Henry Friesen,[9] prolactin is a peptide hormone, encoded by the PRL gene.
