ObGyn Reacts: Unconscious Birth – Didn’t Know I Was Pregnant
  • #1 02-07-2008 11:18 PM by tbn1086Does using antibiotic eye drops while on the pill decrease its effectiveness? Im using ciprofloxacin 0.3% drops for an eye infection. I thought eye drops only have a local effect but I can taste it in the back of my throat so Im not really sure. Anyone know if antibiotic eye drops would decrease the effectiveness of the pill???
  • #2 02-08-2008 05:46 AM by IrishPrinces426Re: birth control and antibiotic eye dropsI was taking antibiotic eye drops for about two weeks and never heard anything about them effecting birth control. Usually my doctor will say something and there is a warning in the information I get on the drug from the pharmacy. The doctor didnt say anything to me and there was nothing about it effecting birth control on the drug information.If you are concerned get in touch with your doctor or pharmacist.IrishPrinces
  • 02-08-2008 03:20 PM by MusicElleRe: birth control and antibiotic eye dropsI think the reason antibiotics effect birth control has to do with how the birth control is absorbed in the digestive system, so I think you fine since your not taking the antibiotics orally.

How To Take Birth Control Pills Correctly

When used as directed, birth control pills are up to 99 percent effective in preventing pregnancy. Most birth control pills are taken daily for 21 days on and seven days off. Some pills are taken for 28 straight days and others for 91 straight days. Pills may be different colors to indicate different levels of hormones. Some days you may take pills that contain no hormones. Theyre meant to keep you in the habit of taking your pills.

Your doctor will advise you about when to start taking your pills. This is usually the first Sunday after your menstrual cycle starts or the first day of your menstrual cycle. You should take your pills at the same time each day. If you dont take your pills consistently, your risk of becoming pregnant increases.

Birth control pills are just one of many birth control options. Other options include:

  • pills
  • implants
  • diaphragms

The U.S. Department of Health and Human Services recommends asking yourself these questions when deciding which option is best for you:

  • Do you want to have children some day?
  • Do you have any medical problems?
  • How often do you have sex?
  • How many sex partners do you have?
  • Will the birth control prevent HIV and other sexually transmitted diseases?
  • How well does the birth control work?
  • What are the side effects?
  • Is it difficult or inconvenient to use?

What Do I Need To Know About Rifamycins

Rifamycins are a class of antibiotics. The most commonly prescribed rifamycin is known by the name rifampin. Rifampin is not prescribed very commonly in the United States.

Rifamycins, are most commonly prescribed for the treatment of mycobacterial infections, including tuberculosis , or for treating travelersâ diarrhea caused by E. coli .

Rifampin can sometimes be used in combination with other antibiotics to treat other bacterial infections too . .)

Rifampin, can speed up the liverâs ability to break down molecules and medications, including hormonal birth controls, which are processed continually through the liver .

For this reason, anyone taking any form of hormonal contraceptive, like the pill, patch, ring, mini-pill, and the implant, who is prescribed rifampin treatment should note that their hormonal contraceptive will not be as effective, and may increase their likelihood of becoming pregnant .

Rifampin does not interact with other forms of birth control, such as the contraceptive shot, the copper IUD, and the hormonal IUD, meaning that you can continue to use these types of contraception while undergoing rifampin treatment .

Anticonvulsants / Mood Stabilizers

If you have epilepsy or bipolar disorder, make sure you speak to your doctor about your medications possible interaction with hormonal birth control. Barbiturate medicines commonly used as anticonvulsants, sleep aids, and mood stabilizers have been known to interfere with birth control these include felbamate, lamotrigine, phenobarbital, and primidone. Other medicines for treating seizures and nerve pain, like oxcarbazepine, carbamazepine, phenytoin, and topiramate, are also known to make birth control less effective. Unfortunately, these negative interactions are a two-way street, meaning they weaken the effects of birth control and birth control weakens their effects too. In any case, if you are on a mood stabilizer or anticonvulsant and want to prevent pregnancy, talk to your doctor about your options.

What Are My Options

Most types of emergency contraception are pills, often called the âmorning afterâ pill. Depending on the brand and dose of emergency contraception pills, you might get one pill or two. These include:

Hormone-based emergency contraception pills. These contain a hormone called levonorgestrel. Levonorgestrel pills are specifically packaged as emergency contraception and do not require a prescription. They include Plan B One-Step and Preventeza, as well as the generic levonorgestrel pills My Way and Take Action.

Ella . Ella is a nonhormonal pill. It contains ulipristal, a nonhormonal drug that blocks the effects of key hormones necessary for conception. It is available only by prescription.

Birth control pills. These can also be used as emergency contraception, but you have to take more than one pill at a time to keep from getting pregnant. This approach works, but it is less effective and more likely to cause nausea than levonorgestrel pills.

Do not take regular birth control pills this way unless you talk to your doctor first. If you are interested in this option, check with your doctor to make sure you are taking the correct pills and dose.

Foods Herbs And Supplements That Can Make Your Birth Control Less Effective

You might not realize that there are certain foods, supplements, and other things you consume that can be getting in the way of how well your birth control works. It sounds crazy, but its actually really easy to stop contraception in its tracks, so make sure its not happening to you by keeping these 14 things out of your diet:

Licorice Its delicious as a snack, but avoid too much of it if youre on the birth control pill. Licorice can boost your blood pressure which isnt a good thing since oral contraceptives do the same thing. It can also effect your reproductive hormones, which could make you fall pregnant!

Grapefruit Its a healthy, tasty fruit, but it can affect your intestinal enzymes that control how your body absorbs certain medicines. Grapefruit also decreases how much estrogen gets broken down by the body, which boosts the hormones presence. It could therefore potentially cause your contraception side effects to be increased.

St. Johns wort This is a herbal remedy people use for treating depression, but it can decrease how well your birth control works, according to Brown University in Rhode Island. Be sure that any liquid extracts, pills, or herbal teas you consume dont contain this flowering plant.

Red clover If youre suffering from bad PMS symptoms, you might reach for red clover to treat it but dont. It contains isoflavones that act like estrogen, so it can increase the estrogen-related side effects of your birth control.

Additional Contraception When Taking Antibiotics

If you’re going to take rifampicin or rifabutin for more than 2 months, you may want to consider starting, or changing to, a contraception method that’s not affected by these medicines.

You should consider doing this if you’re currently using:

If you’re taking rifampicin or rifabutin for less than 2 months and want to continue using the same hormonal contraception, you must discuss this with your doctor.

You may be asked to take this contraception in a different way from usual and use condoms as well.

You’ll need to continue this for 28 days after finishing the antibiotics.

One option for women who have a contraceptive implant and need to take a short dose of rifampicin is a single dose of the progestogen injection.

The implant can stay in place while you’re covered by the injection.

You and your doctor can get up-to-date guidance about contraception and antibiotics from the Faculty of Sexual and Reproductive Healthcare.

You do not normally need to use additional contraception if you’re taking antibiotics other than rifampicin and rifabutin.

But if the antibiotics or the illness they’re treating cause diarrhoea or vomiting, absorption of the contraceptive pill may be affected.

How Does Plan B Work

Whats the Deal with Antibiotics and Birth Control?

It is possible to take the Plan B pill up to 3 days after unprotected sex, even though many people call it the morning-after pill. However, the sooner a person takes Plan B following unprotected intercourse, the more effective it is in preventing pregnancy.

The Plan B pill contains 1.5 milligrams of the hormone levonorgestrel. Levonorgestrel is a synthetic chemical that mimics the natural hormone progesterone. It triggers several responses in the body that prevent pregnancy.

Levonorgestrel ensures that the body is:

  • Preventing ovulation, the process by which the ovary releases an egg. If there is no egg to fertilize, pregnancy is not possible.
  • Thickening the mucus in the cervix, which helps prevent sperm from reaching the uterus and combining with an egg.
  • Thinning the uterine lining, which reduces the likelihood of a fertilized egg attaching to the uterus.

There are many misconceptions regarding how the Plan B pill works. The pill is not an abortion pill as it does not destroy or damage a fetus. Instead, it prevents a pregnancy from occurring in the first place. Once an embryo has implanted in the uterus, Plan B will not disrupt it or cause an abortion.

Anyone who has had unprotected sex or failure of their birth control method can take the Plan B pill. This pill is available without a prescription and has no age restrictions.

Some people should avoid taking Plan B, including those who are:

Most Antibiotics Dont Make Birth Control Less Effective

Reproductive experts told USA TODAY the claim in the Facebook post is false, with one exception: rifampin.

Only rifampin-like antibiotics make your birth control less effective birth control meaning the pill, patch and ring, Dr. Melissa Simon, vice chair of research at Northwestern Universitys Department of Obstetrics and Gynecology, said in an email.

Rifampin, known in the U.S. by the brand names Rifadin and Rimactane, is used in tandem with other medications to treat tuberculosis in numerous parts of the body, according to the Mayo Clinic. It may also be prescribed to asymptomatic patients with meningitis in their nose or throat to prevent spreading bacteria to others.

Dr. Neel Shah, an assistant professor of obstetrics, gynecology and reproductive biology at Harvard Medical School, said rifampin is an older and rarely used antibiotic. But that doesn’t mean contraceptive users shouldnt be wary of other medications and supplements.

Fact check:Pfizer’s FDA-approved vaccine is available in US

There are other examples of prescription medications and herbal remedies that can interact with oral contraceptives, including certain sleep medications and St. John’s wort, Shah said in an email.

I would encourage people to be open with their concerns and communicate with their doctor to make sure they are being prescribed the medications they need effectively, Shah said.

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.

This can be a nice time to try other ways of having sex or being intimate.

Antibiotics May Lessen Effectiveness Of Hormonal Contraception

Birth control: Do antibiotics affect my birth control? | Nurx (2020)

Its safest to take extra precautions to avoid unintended pregnancy, advise researchers

Antibiotics may lessen the effectiveness of hormonal contraceptives, finds an analysis of unwanted side effects associated with the combined use of these drugs, and published in BMJ Evidence Based Medicine.

Women on the Pill should be advised to take extra precautions to avoid unintended pregnancy, when prescribed antibiotics, advise the researchers.

Suspicions that antibiotics, particularly those that cover a wide range of bacteria, known as broad spectrum antibiotics, might reduce the effectiveness of hormonal contraceptives, date back to 1973. Since then several anecdotal reports have also implicated various antibiotics in weakening the effects of hormonal contraceptives.

Current advice, which is based on a few small studies, is that antibiotics, other than those that prompt the production of certain enzymes, dont interfere with hormonal contraceptives.

To explore this further, the researchers drew on reports of suspected unwanted drug side effects, known as Yellow Cards, flagged up by clinicians and the public to the UKs drug and medical devices regulator, the Medicines and Healthcare products Regulatory Agency .

They compared the number of unintended pregnancies reported in 74,623 Yellow Cards for antibiotics in general and in 32,872 for enzyme-inducing drugs with those reported in 65,578 other types of drugs.

How Do I Correctly Take Birth Control Pills

Birth control pills typically come in either 21-packs or 28-packs that include seven sugar pills that make it easier to stay in the habit of taking your contraceptive on the seven “off” days. Some brands can be taken continuously for up to 91 days, so you only have to experience a period four times a year.

Regardless of which brand you take or how frequently you pause for seven days, oral contraceptives should be taken at the exact same time every day to be maximally effective. This is especially true for progestin-only pills.

Another factor that may reduce the effectiveness of birth control pills is proper absorption doesn’t take place. For example if you vomit shortly after taking a dose, it’s unlikely that your body had a chance to absorb the hormones in the pill.

If the antibiotic you’re prescribed causes symptoms of nausea and vomiting, you may want to consider scheduling the time you take your pill when you know you won’t have these symptoms, such as after any bout of nausea has passed or right before you go to sleep.

While it should be taken at the same time each day, you can start taking the pill at any point in your monthly cycle. For example, you can start taking it even if you’re having a period.
