Suppression of Lactation
On this page
Direct answer
Suppression of lactation is the deliberate stopping of milk production after birth, usually when the baby has died, the mother has a condition that makes breastfeeding unsafe, or she chooses not to breastfeed. Non-drug measures such as avoiding stimulation, supportive care and analgesia come first. Where drugs are needed, cabergoline is the usual choice, and bromocriptine is no longer advised.
What you must remember
- Indications: Stillbirth or neonatal death, maternal drug toxicity or serious illness, and maternal choice.
- Non-drug measures: Supportive bra, cold packs and analgesia, with avoidance of breast stimulation.
- Expression: Avoid expressing milk, since removal of milk maintains production and prolongs engorgement.
- Cabergoline: A dopamine agonist that lowers prolactin, given as a short oral course per local protocol.
- Bromocriptine: No longer advised for suppression because postpartum use has been linked to serious cardiovascular and cerebrovascular events.
- Adverse effects: Nausea, headache, dizziness and postural hypotension with cabergoline.
- Caution: Use dopamine agonists carefully in hypertensive disorders and in women with psychiatric illness.
A graded approach from comfort to drugs
The approach is graded, starting with comfort and removal of stimulation before drugs are added. Drugs are reserved for women who remain engorged or distressed after the simple measures.
- Counsel first: Explain that milk production falls over several days and that the process is temporary, with symptoms settling over about one to two weeks.
- Avoid stimulation: Stop feeding and expressing from both breasts, since milk removal keeps production going.
- Relieve discomfort: Use a supportive bra, cold packs and analgesics such as paracetamol or an NSAID as tolerated.
- Check blood pressure: Measure blood pressure and confirm there is no hypertensive disorder before starting cabergoline.
- Give cabergoline: Prescribe a short oral course per the local protocol, using the standard regimen rather than an improvised one.
- Monitor for complications: Review for engorgement, mastitis and breast abscess over the following days, since milk stasis drives infection.
A woman who is comfortable and has no engorgement may need no drug at all.
Where the exam tries to catch you
Questions test the drug of choice, the drug to avoid and the complications to watch for.
- Trap: Using bromocriptine because it is the classic lactation suppressant. Correct: Bromocriptine is no longer advised because it has been linked to serious cardiovascular and cerebrovascular events.
- Trap: Expressing milk to relieve pain. Correct: Expression stimulates production and prolongs engorgement, so analgesia and supportive care are better.
- Trap: Giving a dopamine agonist to a woman with hypertension without review. Correct: Blood pressure is checked first, and caution is needed in hypertensive disorders and psychiatric illness.
- Trap: Assuming suppression is complete within 24 hours. Correct: Production falls over several days, so women need follow-up for engorgement and infection.
Frequently asked questions
Which drug is used for suppression of lactation?
Cabergoline is the drug most commonly used for suppression of lactation in current practice. It is a dopamine agonist that lowers prolactin and is given as a short oral course per local protocol. Bromocriptine is no longer advised because of cardiovascular risks.
Why is bromocriptine no longer used to suppress lactation?
Bromocriptine is no longer used to suppress lactation because postpartum use has been linked to serious cardiovascular and cerebrovascular events, including stroke. Cabergoline has largely replaced it in practice. Its risk profile is the main reason for the change.
Is breast binding recommended to stop milk production?
Tight breast binding is no longer recommended for suppression of lactation because it can cause pain and mastitis. Supportive bras, cold packs and analgesia are preferred instead. Avoiding stimulation is the main non-drug measure.
What complications should be watched for during lactation suppression?
Engorgement, mastitis and breast abscess are the main complications to watch for during lactation suppression. Women should seek care for fever, a red and painful breast or a hard lump. Monitoring matters because milk stasis is the main driver of infection.
