Can Antibiotics Interfere With An Iud

What Else Should I Know About Birth Control And Antibiotics

Pharmacology – Antibiotics, Antinfectives nursing RN PN (MADE EASY)

Some antibiotics can cause nausea, vomiting, and diarrhea. Too much of this could mean your body canât absorb enough of the hormones in your birth control pills to prevent pregnancy.

Your body probably wonât take in enough hormones if you vomit or have a lot of diarrhea within 2 hours after taking a progesterone-only pill or less than 3 hours after taking a combined birth control pill. If this happens, take another pill right away, and your next pill at your regular time.

If you donât get sick again, youâre still protected against pregnancy. If your vomiting or diarrhea goes on for more than a day, your pill may not work as well to prevent pregnancy. Keep taking your pills but use a back-up birth control method and check with your doctor or pharmacist about what to do next.

Finally, remember that no birth control method prevents 100% of pregnancies. Youâll get the most protection from your hormonal birth control if you:

  • Take your pills at the same time each day.
  • Keep patches in place and change them once a week.
  • Get your shot on schedule every 3 months.
  • Replace your vaginal ring as often as directed.

Mood Stabilizer & Epilepsy Medicines

Women taking some medicines to treat bipolar disorder or epileptic seizures have a double reason to choose their birth control carefully:

1) Many of the medicines used to treat epilepsy and bipolar disorderBarbituates, Carbamazepine, Oxycarbazepine, Phenytoin, Primidone, Topiramate, Felbamate, and Lamotrigine when taken alonemake the pill, patch, ring and mini-pill less effective, increasing the chance of an accidental pregnancy.

2) Theres some evidence that these methods of birth control change the effectiveness of those particular medicines, too. That increases the chance of having a seizure, or a manic or depressive episode. If you have epilepsy or bipolar disorder, its really important to talk with your provider about what birth control method is best for youthere are still good options!

The Risk Of Expulsion And Perforation Are Very Low But They Do Occasionally Happen

IUDs come with a small risk of expulsion, which is when your body starts to push the IUD out of you. There isnt a ton of research on this out there, but the average expulsion incidence rate is between 2 to 10% of users, the ACOG says. Risk factors include recently having had the IUD inserted, getting it placed right after childbirth, and history of heavy or prolonged periods, among others. Though you dont really need to stress about this possibility, if it were to happen to you, you might experience symptoms like bleeding and cramping, feel something hard coming from your cervix, or see the IUD somewhere outside of your body however, it is possible to experience an expulsion without any major symptoms.

IUDs can also cause perforation, which is when the device pushes through the wall of your uterus. It sounds alarming, but again, the risk is really low. According to a 2015 study published in the journal Conception, out of 61,448 people who had an IUD, only 20 with the copper form experienced a perforation. In fact, perforation most often happens due to an error during placement. Much like with expulsion, this isnt something that needs to keep you up at night, but if you were dealing with perforation, you would potentially experience pelvic pain , though you might not experience any major symptoms at all.

Other Medications That Mess With Birth Control

Grab the Condoms  These Are the Medications That Affect Birth Control

While antibiotics have been taking the unplanned pregnancy fall for years, there are other medications that may actually be making your birth control less effective. Any medication that has vomiting or diarrhea as a side effect or if youre experiencing vomiting or diarrhea because of your illness has the potential to make oral hormonal birth control less effective. Thats because if youre taking it orally , then it could be coming back up or processed too quickly through your intestine to get enough of the hormones in your blood stream. Without those hormones at sufficient levels to block ovulation, you could ovulate and therefore could get pregnant if you have sex at the right time of the month.

And remember how I said that the reason rifampin messes with your birth control is because its enzyme-inducing? Well, it turns out its not the only one. Other drugs that are enzyme-inducing include Modafinal , some epilepsy drugs , and some antiretroviral drugs that are used to treat HIV . So if youre taking one of those medications, consider either using back up contraceptives or switching to a new method altogether.

Not Taking Oral Contraceptives Each Day At The Same Time Can Reduce Their Effectiveness

If you’re relying on a birth control pill to prevent pregnancy, sticking to a consistent pill-taking routine is important.

“For oral contraceptives, the most important thing is to take the pill every day at the same time. Missing one pill, especially if it is the first pill in the pack, increases the risk of getting pregnant,” Dr. Tsvetelina Velikova of MedAlertHelp told INSIDER.

If you do miss a pill, you may want to speak to your healthcare provider and use another form of birth control, such as a condom while you figure out your next steps. Planned Parenthood’s website also has a tool that can help you identify which steps to take if you have missed a pill based on the brand of oral contraceptive you’re taking.

Medications That Interfere With Birth Control

Which Medications Stop Hormonal Contraceptives From Working

Progestin is a hormone that is a common ingredient in different types of hormonal birth control. It protects against pregnancy by stopping ovulation and/or thickening the cervical mucus.

In most birth control pills, patch, and vaginal ring, estrogen is combined with the hormone progestin in order to prevent ovulation.

And although human behavior and error is a common reason why hormonal birth control may fail, other factors including medications may also make them less effective.

Heres how these medications can interact with a certain type of hormonal contraceptive method:

Search Methods For Identification Of Studies

Chances of pregnancy with IUD if taking contraceptives after unprotected contact? – Dr. Shailaja N

Electronic searches

In February 2012, we searched the computerized databases MEDLINE using PubMed, POPLINE, and the Cochrane Central Register of Controlled Trials . In addition, we searched for recent clinical trials through and the International Clinical Trials Registry Platform . The search strategy is given in Appendix 1. The previous search strategy, which also included EMBASE, can be found in Appendix 2.

Searching other resources

For the initial review, we reviewed the reference lists of identified articles and wrote to IUD experts on several continents to seek trials we might have missed. The pilot study for the Los Angeles trial was published separately as Walsh 1994. We contacted these investigators to get the number of women who made one or more unscheduled visits, but this information had not been collected in the pilot phase. Since the pilot study for the main Kenya trial was not published, we contacted the investigators to get these data. We attempted to contact one author by mail but without success.

How Do These Meds Mess With Birth Control

For the science geeks among us, heres how this works: its all about metabolism, the process by which our bodies use and clear medicines. Just like with food, the body has an intricate and multi-step process for breaking down medicines, using them, and then clearing them from the body.

One of the key players for medicines is an enzyme called the P450 system. The P450 system helps process both of the hormones in the pill, the patch, and the ringestrogen and progestin. Some medicines speed up or slow down this enzyme system. If the system is revved up, it will go to work breaking down and removing the hormones faster than normal, resulting in lower levels of the hormones to get the job done. It can result in such low levels of hormone that the pill, patch, or ring dont work.

Get A Fertility Cleanse

Getting fertility cleanse will prove to be a great way to normalize your body after an IUD removal as the IUD affects the cervical mucus and uterine environment. A fertility cleanse helps remove toxins from your body to improve the overall health. But it primarily helps clean the liver, fertility, and the uterus, which thus makes the body ready for conception.

What To Do If Youre On A Medication That Might Affect Your Contraception

If youre on medication that can change how effective your hormonal contraceptive is, its important to take other steps to avoid an unintended pregnancy. This means using a barrier contraceptive like a condom or diaphragm.

Dont try to cancel out the antibiotics by doubling up on birth control pills the way the medications interact in your body is complicated and unpredictable, so taking a bigger dose of contraceptives doesnt work.

It isnt always clear how long antibiotics continue to affect hormonal birth control, so doctors usually recommend continuing to use a barrier method or alternative to hormonal contraception to prevent pregnancy for at least seven days after the end of the antibiotic course. This can be a nice time to try other ways of having sex or being intimate.

How Does It Happen

Can My Medications Interfere With My Birth Control?

There are a few reasons pregnancy could occur in people with an IUD. In some cases, a person could become pregnant before the IUD is effective since not all types are effective immediately.

Copper IUDs, like Paragard, protect against pregnancy immediately because the copper changes the environment in the uterus, making it toxic to both the sperm and the egg. This prevents the sperm from reaching the egg and the egg from attaching to the uterine wall.

Hormonal IUDs, like Mirena or Kyleena, take about seven days to start working. These types are generally considered effective immediately if inserted during your period because of where you are in your menstrual and ovulation cycles.

If you have a hormonal IUD inserted, its recommended to use a backup contraceptive method or abstain from intercourse for seven days.

In other cases, pregnancy could occur if the IUD shifts its position. In a small number of people, the IUD may slip partially or entirely out of the uterus . If the IUD shifts, even partly out of position, it will no longer be fully effective at preventing pregnancy.

Another potential way pregnancy can occur is if the IUD remains in your body longer than its recommended expiration date. The amount of time an IUD can stay in and remain effective depends on the type of IUD. The manufacturer recommendations for a few IUDs are:

  • Skyla: Up to three years
  • Kyleena: Up to five years
  • Mirena: Up to seven years
  • Paragard: Up to 10 years

What Does The Research Say

According to the clinical advice, experts and womens health providers, only one antibiotic – rifampin , and to a lesser extent rifabutin – have been proven to make the birth control pill less effective.

  • Rifampin lowers the effectiveness by decreasing the birth control hormone levels in women taking oral contraceptives. The hormone levels are needed to prevent ovulation.
  • Rifampin can induce enzymes in your liver that will break down estrogen faster than normal. Lowering hormone levels can reduce the effectiveness of your birth control.
  • Rifampin can also lower the effectiveness of the transdermal birth control patch and the vaginal ring , so an added barrier method of birth control should be used with these products.
  • A nonhormonal method of birth control – for example, a condom, diaphragm, or copper IUD, is recommended with rifampin use. Depo-Provera, the birth control shot, may be another option.

A 2018 review published in the American Journal of Obstetrics and Gynecology concurred with this information. Researchers completed a literature review of multiple studies that met inclusion criteria. The authors concluded that most women can expect no reduction in effectiveness with the use of hormonal contraceptives and antibiotics .

A review from the Journal of the American Academy of Dermatology states that pharmacokinetic evidence demonstrates that levels of oral contraceptive steroids are unchanged with combined administration of antibiotics, including:

Will Emergency Contraception Like Plan B Work If I Am On These Medications

Emergency contraception like Plan B may not work if you:

  • Weigh over 165 pounds

  • Take anti-seizure medications, antibiotics for TB, HIV medications, or St. Johns Wort

  • Have recently used anti-seizure medications, antibiotics for TB, HIV medications, or St. Johns Wort

In these cases, the best method of emergency contraception is the copper IUD, for example, ParaGard. This will need to be inserted by a trained healthcare professional within 5 days of having unprotected sex. For more information about emergency contraception, see our blog post here.
