How Antibiotics Might Affect Birth Control

Some types of antibiotics have the potential to affect birth control because they can alter the bodys hormone levels. Hormonal birth control methods that these antibiotics might impact include:

All four of these birth control methods contain the hormones estrogen and/or progestin which thickens the mucus in the cervix, making it difficult for sperm to fertilize an egg, and thin the lining of the uterus to reduce the chance of getting pregnant. The methods that contain estrogen also prevent you from ovulating, while progestin-only methods stop ovulation but not consistently. Certain antibiotics can lower the levels of estrogen and progestin in your body, potentially to the point of affecting your birth control.

Theoretically, antibiotics might also reduce your birth controls efficacy by interrupting the recirculation of estrogens in the body a process called enterohepatic circulation. They do this by killing the bacteria in the small intestine that help break the hormone down and redistribute it within the body.

For these reasons, many manufacturers have historically placed warnings on antibiotic labels to inform women about this risk. Over the years, scientists have done many studies on various types of antibiotics effects on hormonal birth control to determine which ones you should and should not take at the same time.

Antibiotics That Can Affect Birth Control

Researchers have only proven that two types of antibiotics can affect the efficacy of your birth control:

  • Rifampin: Health care providers prescribe this medication to treat tuberculosis. Rifampin causes the enzymes in your liver to break estrogens down faster than normal, lowering those hormone levels in your body and possibly reducing your birth controls efficacy. Some women might experience spotting between their periods while taking rifampin, but this doesnt mean their birth control isnt working.
  • Rifabutin: Health care providers prescribe this medication to prevent an infection called mycobacterium avium complex in HIV patients, as well as to treat tuberculosis. It, too, reduces the levels of birth control hormones that suppress ovulation but to a lesser degree than rifampin.

Both of these medications belong to a class of antibiotics called rifamycins. Scientists have not been able to prove that any other rifamycins, however, affect birth control.

  • The area around the implant may be bruised and tender for a few days.

Acne With Other Types Of Birth Control

Acne can be a side effect of other types of progestin-only birth control. These methods include:

  • Hormonal intrauterine devices : After a healthcare provider inserts an IUD in your uterus, it can last for 37 years, depending on the brand.3
  • Mini-pill: You would take this pill daily to prevent pregnancy.13
  • Birth control shot: A healthcare provider would give you this injection of progestin every three months.13

Your skin may respond differently to each progestin-only method. Similar to Nexplanon, scientists don’t know whether these hormonal contraceptives are responsible for the acne.8,10 But research suggests that IUD users with a previous history of acne were more likely to have severe acne and need antibiotic treatment.10

Does Nexplanon Become Less Effective

Nexplanon prevents pregnancy by continually releasing a low dose of progestin over a three-year period. The amount of progestin released slowly decreases over time. By the end of the third year, the dose released is too small to prevent pregnancy, which is why the implant must be removed at that time.

How To Prevent Birth Control Ineffectiveness

Always talk with your doctor about birth control interactions before taking new medications, including vitamins or over-the-counter medications. Ask if the medication or supplement will interfere with your birth control effectiveness. Even if more research is needed, its generally better to err on the side of caution. You can use backup forms of birth control in addition to oral contraceptives when taking medications that interfere with the effectiveness.

If you forget to use a backup method, you can take over-the-counter emergency contraception for up to five days after intercourse. For long term medications, such as retrovirals, diabetes medications, or anticonvulsants, it is best to talk with your provider about other contraception methods, such as long-acting reversible contraception or injectable progesterone.

How Is A Contraceptive Implant Fitted Or Removed

The Nexplanon implant is an incredibly quick and painless procedure. First, a local anesthetic will be applied to the upper arm to numb the area, then your doctor or nurse will inject the small flexible rod just under your skin.

The incision is slightly bigger than a typical injection, but there will be no need for stitches and any bleeding will subside relatively quickly.

After 3 years, it will be time to have your implant removed. This process is equally straight forward that involves a minimal incision and removal via a tweezer-like instrument.

When It Starts To Work

Although the implant can be administered at any time, if it is fitted after the first 5 days of your menstrual cycle, you will be required to still use other forms of contraceptive for the subsequent 7 days. Protection is immediate if fitted during the first 5 days of your cycle, before day 21 of giving birth, andimmediately after an abortion or miscarriage.
