Is hormone replacement therapy done with micronised progesterone?

Oestrogen can stimulate the lining of the womb. Micronised progesterone is a form of progesterone used to help counter that stimulation, reducing the chance that the lining becomes too thick. It may be taken by mouth or used vaginally, depending on the prescribed plan. The schedule can be continuous or arranged for part of a cycle, particularly while periods are still occurring. The choice depends on symptoms, menstrual pattern, whether the womb is present, and other health factors.

Tell the prescriber about unexplained vaginal bleeding, previous blood clots, liver problems, migraine, breast concerns, and medicines or supplements. Keep a record of bleeding and symptoms after starting treatment. Follow the prescribed timing and route; do not add progesterone or change the dose independently. The treatment plan may need adjustment if bleeding continues, sleepiness occurs, or symptoms remain troublesome.

Arrange prompt clinical advice for unexpected, heavy, prolonged, or recurrent bleeding, especially after a period without bleeding. Seek urgent help for chest pain, sudden breathlessness, coughing blood, one-sided leg swelling, severe headache, weakness, or trouble speaking. These symptoms need assessment regardless of how long you have used hormone therapy.

Ask whether micronised progesterone is needed with your oestrogen, which route and schedule fit your situation, how bleeding will be monitored, and what symptoms should trigger a review.
