Mirena Dosage: An Introduction
There is only one standard dose of Mirena®
. As always, do not adjust your Mirena dose unless your healthcare provider specifically instructs you to do so.
Mirena Dosing for Birth Control
Your healthcare provider will insert one Mirena device into your uterus, where it can stay in place for up to five years. If you desire, it can be removed earlier. After five years, if you wish to continue using Mirena, your healthcare provider can remove the old Mirena and insert a new one.
Each Mirena device contains a total of 52 mg of levonorgestrel (a progesterone hormone). At first, the hormone is released into the body at a rate of about 20 mcg per day, although this decreases over time.
Mirena should be inserted within seven days after the start of your period (this helps ensure that you are not pregnant). It can be inserted immediately after a first trimester
abortion or miscarriage, but should not be inserted immediately after birth or following a second trimester
abortion or miscarriage. In these cases, your healthcare provider will wait until your uterus has returned to its normal size before inserting Mirena.
