9 Mirena Side Effects You Should Know About
You know those boots you never knew you needed until you tried them on, and now you can’t live without them? Well, the Mirena IUD is the birth control version of black ankle booties — versatile, durable and with the added bonus of preventing pregnancy.
Mirena is basically a “set it and forget it” contraceptive. You don’t have to do anything to maintain it, you can leave it in for up to five years, and since it’s 99 percent effective it’s more reliable than the Pill or condoms. Insertion is pretty simple, too. Your doc can do it in their office and you should be in and out in under 15 minutes.
Planned Parenthood: the copper IUD, which uses copper ions to prevent fertilisation, and hormonal IUDs, which include Mirena. by slowly releasing progestin, a synthetic form of the hormone progesterone, into your uterus. The progestin thickens your vaginal mucous, thins out your uterine lining, and can prevent your ovaries from releasing an egg, all of which prevent any rogue sperm from making a baby in you, explains Dr Sherry Ross, an ob-gyn, women’s health expert and author of She-ology., according to
Considering getting the Mirena? There are few Mirena side effects — good and bad — you should know about first. “What side effects you experience really depends on how sensitive you are to man-made or synthetic progesterone hormones and that will be different from woman to woman,” Ross says. Here what to look out for:
1. Say Bye-Bye To Your Period
In most cases, your period will become significantly lighter and shorter; for 20 percent of women, it will disappear all together. “The Mirena was designed to give you a lighter or non-existent period, which is a welcomed side effect for many women,” Ross says. In fact, doctors often use the Mirena to treat women with irregular and heavy periods or conditions like endometriosis, she adds.
2. Or Hello To The Longest Period Ever
A small percentage of women using the Mirena have persistent irregular bleeding or spotting, Ross says. It’s normal to have some bleeding and cramping in the week after insertion, and spotting for up to three months afterward as your body adjusts to the hormone, but if the bleeding lasts longer than three to six months, you need to see your doctor and discuss getting it removed, she says.
3. Prepare For Nausea
Nausea or an upset stomach is a commonly reported side effect of all types of hormonal birth control, including Mirena. However, an IUD like Mirena is the best of the hormonal options for women with sensitive tummies. Because of its location in the cervix, it bypasses the stomach all together, unlike a pill you have to swallow or an injection that goes through your blood stream, Ross says.
4. Watch Out For Cysts On Your Ovaries
The Mirena causes about 12 percent of women to grow one or more ovarian cysts, sometimes called enlarged follicles. These cysts normally go away on their own, and you likely won’t even know they are there. But in rare cases, they can cause pain or require surgery. If you feel sharp pains that last more than a few hours or increasing pain on either side of your abdomen, give your doc a call, Ross says.
5. Know That In Very, Very Rare Cases, It Could Fall Out
This may be due to improper placement of the Mirena, pregnancy, or something (like a menstrual cup) accidentally dislodging it, according to the manufacturer. “Symptoms of partial or complete expulsion may include bleeding, pain and an increase in menstrual flow,” they write. (Side note: It is also possible for the Mirena to “migrate” to places it shouldn’t be or become embedded in the uterus or other tissues.) “If this occurs, Mirena may be replaced within seven days of a menstrual period after pregnancy has been ruled out. If you think that Mirena has come out, use a back-up form of birth control such as condoms and spermicide and call your healthcare provider,” the Mirena website instructs.
6. Monitor Changes In Mood
Mess with your hormones and you have the potential to mess with your mood, Ross says. How, exactly, the Mirena changes your mood, and how intensely you feel the change, depends on your unique body chemistry.
Some women report feeling more even and stable while others report an increase in depression and anxiety, she says. If you’re unsure how you’ll be affected, it’s worth it to keep careful notes after the insertion, tracking your mood. Talk to your doctor if you feel like it’s hurting your mental health, she says.
7. Be Aware Of Increased Risk Of Infection
All IUDs, including the Mirena, up your risk for bacterial vaginosis, an infection characterised by a “fishy” or bad smell, says Dr Richard Krauss. You may also have discoloured discharge and pelvic pain. These symptoms warrant a call to your doc ASAP before the infection spreads. The infection can be treated with a course of antibiotics.
8. Count On Changes In Your Cramps
One of the most commonly reported side effects of the Mirena are intense cramps, particularly in the month after insertion. However, these should lessen considerably as your body adjusts, Krauss says. In fact, over time the Mirena can actually reduce the pain and cramping you used to experience with your periods, he adds. If yours get worse or lasts more than a month, it’s time to check in with your doctor to make sure it hasn’t moved or become displaced.
9. Be Ready For A Bit Of Bloat
While it’s not listed on the official side effects, lower-belly bloating is a relatively common complaint Ross hears. This may be because of progesterone’s natural muscle-relaxing properties, making your gut a bit slower. On its own this isn’t much to worry about but if you experience a lot of pain with it or severe constipation, call your doc, she adds.
