Should You Try a Birth Control Cleanse?

Most birth control methods are already out of your system in a few days

The idea of hitting a reset button for your body and your fertility after getting off birth control may be tempting. But is it realistic? Or necessary? Ob/Gyn Ashley Brant, DO, sets the record straight on birth control cleanses.

What is a birth control cleanse?

Birth control cleanses are products — most often drinks — sold with the premise that your hormones should be rebalanced and your uterus detoxed after getting off birth control. They often include vitamins, minerals and herbal supplements like chasteberry.

“Most birth control cleanses are like a multivitamin. But they’re not approved or regulated by the U.S. Food and Drug Administration,” Dr. Brant says.

Manufacturers claim the types of birth control methods that release synthetic hormones into your body (we’re looking at you, pill) upset your body’s natural state. They claim they wreak havoc on your:

  • Fertility.
  • Hormone levels.
  • Liver health.
  • Uterine health.

How long does birth control stay in your system?

“Most birth control methods are completely out of your system within a few days,” says Dr. Brant. “That’s why you take birth control pills every day — they wear off within 36 hours. There’s no harmful buildup of hormones in your system.”

The effects of an intrauterine device (IUD) last slightly longer. “But even the most conservative estimates say your body is clear of synthetic hormones within a week of having the IUD removed,” Dr. Brant explains.

The one exception? The Depo-Provera® shot, a progestin-only contraceptive injection you get every three months. Progestin is the synthetic version of progesterone, a hormone your ovaries naturally release.

“While the injection’s effects are intended to last for at least three months, there’s some evidence that it can take up to a year for fertility to return after your last shot,” Dr. Brant says, “but there’s no evidence that taking vitamins or supplements speeds up that process.”

Do birth control cleanses work?

In short, no. “A cleanse is not necessary after birth control. There’s no evidence that taking vitamins helps you more quickly process the hormones in birth control. Your liver quickly processes most reproductive hormones, such as progesterone and estrogen, on its own,” Dr. Brant explains.

Side effects of birth control cleanses

While you don’t need to do one, Dr. Brant says there’s probably no harm in birth control cleanses. “There have, however, been a few case studies where people have overdosed on over-the-counter vitamins, so buyer beware of that potential risk,” she warns. “The quality of vitamins and supplements can also vary from product to product.”

Another potential birth control cleanse side effect has to do with your bottom line.

“They’re a marketing gimmick. Manufacturers prey on people’s fears and concerns about hormones so you’ll buy these expensive products,” she says. “Taking a prenatal vitamin would be a lot cheaper for similar potential benefits.”

But what about post-birth control syndrome?

The term “post-oral contraceptive syndrome” was first coined in 2008 in a book written by a doctor/herbalist. Now known as post-birth control syndrome, naturopathic doctors describe it as a set of symptoms that may happen after you stop taking birth control pills. These symptoms can include:

  • Acne.
  • Digestive problems, including gas, bloating and upset stomach.
  • Fertility problems.
  • Hair loss.
  • Irregular, heavier or more painful periods.
  • Migraines.
  • Weight gain.

But here’s the catch: “Post-birth control syndrome is not a medically accepted term. It’s not well defined and doesn’t have diagnostic criteria in the medical field,” Dr. Brant says. “Birth control often treats and prevents these troublesome symptoms — so, it’s more likely that birth control had been masking these problems when you were on the pill, not that going off of birth control caused them.”

It’s also important to note that the idea that birth control negatively affects future fertility is more superstition than science. In fact, studies show that it doesn’t affect your ability to conceive after you stop using it.

But if you just don’t feel right after getting off birth control, Dr. Brant says self-treating with a cleanse isn’t your best option. “Instead, talk to your doctor,” she advises. “It’s rare for ovulation to take a while to come back. Most people will start ovulating again within one to two months. But if not, there are things we can do to help get you back on track.”
