What is Lactation suppression and explain in detail?
Lactation suppression refers to the act of suppressing lactation by medication or other non pharmaceutical means. The breasts may become painful when engorged with milk if breastfeeding is ceased abruptly, or if never started. This may occur if a woman never initiates breastfeeding, or if she is weaning from breastfeeding abruptly. Historically women who did not plan to breastfeed were given diethylstilbestrol and other medications after birth to suppress lactation. However, its use was discontinued, and there are no medications currently approved for lactation suppression in the US and the UK. Dopamine agonists are routinely prescribed to women following a stillbirth in the UK under the NHS.

Reasons
After birth, some women may desire to stop the production of breast milk, for example when the mother decides to bottle feed from birth, or in the case when the infant dies or is surrendered at birth. Additionally, women who are breastfeeding may need to stop breastfeeding abruptly, for instance if she is taking medication contraindicated for breastfeeding or undergoes surgery. The abrupt weaning process may lead to severe engorgement, extremely painful breasts, and possibly mastitis. Up to one third of women who do not breast-feed and who use a brassiere or binder, ice packs, or analgesics may experience severe breast pain. Specific studies of nonpharmacologic methods of lactation suppression were limited and inconclusive. Available data suggest that many women using currently recommended strategies for treatment of symptoms may nevertheless experience engorgement or pain for most of the first postpartum week.

Methods
Medication
Dopamine agonists are currently the preferred medication for suppressing lactation, which work by suppressing prolactin production. Cabergoline (Dostinex™) is currently most effective option currently available, as it is available as a single dose (as opposed to bromocriptine which must be taken twice daily for 2 weeks.)  It may be prescribed in the case of breast abscess. Although the preferred method of treatment for breast abscess and mastitis is actually to continue breastfeeding, if the decision is made to stop breastfeeding, then chemical lactation suppression is indicated, particularly for severe cases. Carbergoline is not indicated for treatment of discomfort caused by engorgement.  In the UK dopamine agonists are routinely prescribed following a stillbirth. Pre-eclampsia is a contraindication for prescribing dopamine agonists.In the past, hormonal therapies such as diethylstilbestrol were routinely used in the postpartum period, but these are no longer recommended due to side effects such as nausea and vomiting, and severe potential side effects such as thromboembolism, cerebral accident, and myocardial infarction. Estrogen containing birth control pills may have the same side effect, but like diethylstilbestrol is inappropriate for use in the postpartum period due to the risk of side effects
