Medicines are one of the treatments used for heavy periods. A number of factors are considered when working out the best medicine for you.
The medicines below are used to reduce heavy periods. The choice of which treatment is recommended for you will depend on your need for birth control (contraception), whether you wish to have children in the future and other medical concerns you may have.
The Mirena IUD is a small plastic device that is inserted into your womb. It slowly releases a small amount of the progestogen hormone (as levonorgestrel) directly onto the lining of your womb. This makes the lining of your womb thinner, making you less likely to have menstrual bleeding and reducing heavy periods.
Once fitted, the Mirena lasts for up to 5 years. It can reduce menstrual (period) bleeding by up to 90%. It also acts as a contraceptive. However, it can cause irregular bleeding when first inserted. Read more about Mirena IUD for heavy periods.
