How long does a hormonal coil take to work for adenomyosis?

A hormonal coil sits inside the womb and releases a progestogen near the womb lining. This can make the lining thinner and reduce the amount of bleeding during periods. It may also lessen cramping over time, although the response depends on how adenomyosis affects your womb and on your symptoms before insertion.

Irregular bleeding, spotting and period-like cramps are common soon after insertion. These changes often settle gradually, but persistent or troublesome symptoms deserve a review. The coil does not remove adenomyosis, and it may not relieve every symptom, such as pressure or pain between periods.

Keep a simple record of bleeding days, pain and any medicines you use so you can describe the pattern at follow-up. Use pain relief only as advised for you, and check how to feel for the threads if your clinician recommends it. Ask when the coil should be checked and what improvement to expect by that visit.

Seek prompt medical advice for severe or worsening pelvic pain, fever, unusual or foul-smelling discharge, very heavy bleeding, dizziness, or concern that the coil has moved or come out. Sudden severe pain or fainting needs urgent assessment. Contact your clinician if pregnancy is possible with the coil in place.

Ask when your symptoms should be reviewed, which bleeding changes are expected, what alternatives are available if pain continues, whether the coil suits your pregnancy plans, and how its position will be checked if the threads cannot be felt.
