Which birth control is best during perimenopause?

If you’re in your 40s or 50s, then you’d be forgiven for assuming that using birth control is a thing of the past. After all, sex education classes have led lots of us to believe that you can’t get pregnant after 40 without the help of fertility treatment. But that’s not always the case. 

Research shows that pregnancy is still possible during perimenopause (the years transitioning through menopause), even though your fertility does start to decline after the age of 35. And there’s another important reason to think about contraception. 

Combined oral contraceptive pills have been found to act like hormone replacement therapy (HRT), so they can be used by some people to help with perimenopause symptoms like hot flashes, irregular periods, and mood swings.

Let’s get the expert lowdown on birth control for perimenopause, from the type that may be best for you to when to stop taking it.

Key takeaways

• During perimenopause, you still have a chance of getting pregnant every cycle.
• Even if your periods are irregular, it’s possible to ovulate (when your ovary releases an egg), which means you can still get pregnant.
• To avoid an unplanned pregnancy, you will need to use contraception until you have officially reached menopause (12 months after your last period).
• Combination oral hormonal contraceptives may also help to relieve hormone-related perimenopausal symptoms, such as hot flashes and mood swings.

Why take birth control during perimenopause?

There are two main reasons why you might consider taking birth control during perimenopause: to prevent unplanned pregnancy and/or to manage perimenopausal symptoms.

Before we dive into the best birth control for perimenopause, let’s clear up any confusion about what perimenopause actually means. Perimenopause is the years leading up to menopause (your final period) and the 12 months after. It can begin somewhere between your late 30s and 50s. You might experience symptoms like hot flashes, brain fog, and mood swings during perimenopause. 

You’re then officially diagnosed as having hit menopause when you haven’t had a period for 12 months (usually between the ages of 45 and 55). It’s a retrospective diagnosis, which basically means the diagnosis happens after the event. From that point on, you are postmenopausal. You don’t need to use contraception to avoid pregnancy anymore, but you might still want to take the pill to help with symptoms. Remember too that you can still catch sexually transmitted infections, so using condoms is still important. 

Can you still get pregnant during perimenopause?

Research shows that pregnancy is still possible during perimenopause. If you’re not planning on getting pregnant, then it’s important to use contraception. You might think that if your periods have become more irregular or you’ve started to notice some symptoms associated with perimenopause, then this doesn’t apply to you, but it does. 

“Most women at this time still ovulate, although ovulation may be irregular and may involve more than one egg per cycle,” says Dr. Ruth Olumba, obstetrician, gynecologist, and gynecologic and cosmetic surgeon, Texas, US. “Without a form of birth control, women can get pregnant as long as they are ovulating, even during perimenopause, although their fertility rate is lower.” 

How can birth control help with perimenopause symptoms?

Taking birth control can help with symptoms like hot flashes, mood swings, and irregular periods, which can be hard to navigate during perimenopause.

“Combination oral hormonal contraceptives that include both estrogen and progestin are useful as both birth control and to manage symptoms of perimenopause,” Dr. Olumba, OB-GYN, explains.

Why? Well, hot flashes are known as vasomotor symptoms. These are thought to be caused by fluctuations in your hormones, specifically estrogen. Like hormone therapy, the combined pill works by regulating your hormone levels, so those annoying perimenopause side effects should ease off if you only need a low dose.

The best contraceptive for perimenopause

The best contraception for perimenopause really depends on the person taking it. We are all different, and certain types of birth control may suit you better than others. The options include pills, injections, implants, intrauterine devices (IUDs), and barrier methods.

Which birth control pills can you take during perimenopause?

While there are lots of different brands, they can be split into two main types: 

Combined oral contraceptive pill

The combined oral contraceptive pill (COCP) includes both the hormones estrogen and progestin (the synthetic version of progesterone). You might consider taking the COCP instead of hormone therapy to help regulate your periods and relieve perimenopause symptoms. 

However, not everyone can take COCP. This is because estrogen-based contraceptives can slightly increase the risk of some medical conditions (including breast cancer and blood clots). Your doctor will ask you about your family and medical history before prescribing it. They’ll also consider age and some lifestyle factors, like weight and whether you smoke.

Progestin-only pill

As the name suggests, the progestin-only pill (POP or the mini pill) only contains progestin. It suits some people better than other birth control options, as it has fewer associated risks and can also help to regulate heavy and painful periods. If you take POPs, your periods might become irregular or stop altogether. 

However, “Progestin-only birth control, although effective in preventing pregnancy, will not offer the additional benefit of perimenopause symptom prevention or therapy,” says Dr. Olumba, OB-GYN. This is because it doesn’t contain estrogen.

Is the contraceptive injection a good option in perimenopause?

The contraceptive injection is a good option if you get heavy periods or frequently forget to take a daily pill. It lasts eight or 13 weeks, depending on the type of injection you have. 

While some types of contraceptive injection release only the hormone progestin into your bloodstream to prevent pregnancy, they don’t have the benefits of soothing estrogen-related symptoms, which is something to think about.

How can the implant help during perimenopause?

The contraceptive implant may help with heavy, painful periods, but because there’s no estrogen, it won’t relieve vasomotor symptoms, like hot flashes and night sweats.

The implant is a small plastic rod that is inserted under the skin in your upper arm. It contains progestin and helps prevent pregnancy by pausing ovulation. 

Why should you use barrier methods in perimenopause?

Barrier methods are the only contraception that reduces both the risk of unplanned pregnancy and catching/spreading sexually transmitted infections. But they’re nonhormonal, so they won’t help manage hot flashes or mood swings.

Barrier contraceptive methods include male (external) condoms, female (internal) condoms, diaphragms, and cervical caps. You can use these forms of birth control on their own or alongside others. 

What types of IUD can you use during perimenopause?

There are two different types of intrauterine devices (IUDs) to choose from: copper IUDs or hormonal IUDs.

An IUD or coil is a small, T-shaped device that is inserted through your cervix and placed inside your uterus to prevent unplanned pregnancy. You might have heard IUDs referred to as long-acting reversible contraception. This means that you can have the IUD inserted and then don’t need to think about it. 

Copper IUD 

The copper IUD is a nonhormonal device that releases copper to stop you from getting pregnant. You can have a copper IUD for up to 10 years, which means it’s a great option if you don’t want to switch up your birth control method for a while. However, since they don’t have any hormones, they won’t have any hormone replacement therapy (HRT) impact, and you might end up with heavier periods.

Hormonal IUD

Like the copper IUD, a hormonal IUD is inserted into your uterus. These release progestin to stop ovulation and protect you from unplanned pregnancy. If you have heavy or irregular periods, then your doctor might recommend a hormonal coil. Don’t be fooled by the name. These IUDs are estrogen-free, so they won’t help with vasomotor symptoms alone, but can be used with estrogen as HRT. If you combine birth control alongside HRT, it’s always a good idea to talk to your doctor about any side effects or risks.

When can you stop taking contraception?

Choosing when you might want to stop taking contraception is just as personal as picking the right type for you. There’s no one-size-fits-all answer. It’s totally dependent on what you need and if you’re experiencing symptoms associated with perimenopause. Generally speaking, if you’re otherwise healthy and have passed menopause, your doctor may recommend that you stop taking birth control after the age of 55. 

If you’re thinking about stopping birth control, then your first step should be a conversation with your doctor. This is especially important if you think you might be postmenopausal. “When a woman is no longer ovulating, there is a decision to be made as to whether to go off birth control and transition in an immediate or delayed fashion to hormone replacement therapy if desired,” Dr. Olumba, OB-GYN, says.
