The only antibiotic known to affect birth control is rifampin. Most others have been shown to not significantly increase risk of pregnancy, though studies are not perfect as birth control use is not perfect either. If you are that worried, just use backup protection for the time you are on the antibiotic.

Antibiotics and Birth Control

Yes, but your doctor wouldn’t give you an antibiotic for no reason. Using backup protection is your best bet

Yes you need to use back up protection the whole duration your on your antibiotics and not miss a dose of your birth control if taking the pill!

Yep, my pharmacist told me this with Amoxicillin.

Again with this question???

Yes. If you are on birth control and take antibiotics then you should use condoms or abstinence until after the next month or you might end up pregnant…

Yes, they should tell you that when you are given them! Don’t have sex when you are taking antibiotics! A kid is NOT worth not holding out for a bit🤣

I am surprised everyone doesn’t know this…

I am a pharmacist and most commonly prescribed antibiotics don’t actually have any interaction with birth control. Rifampin is the main exception, but it is not a super common antibiotic used. I used to believe this prior to pharmacy school, but in general it is a myth.

Yes some can!Talk to the pharmacist when getting antibiotics to see if that kind affects BC.

yes it does, I got pregnant all three times while on antibiotic while on birth control, it wasn’t till my third pregnancy the doctor said something about antibiotics making birth control ineffective. No one told me that till after I was pregnant for the third time.

You should check with your doctor for your specific birth control and antibiotics but yes, my doc has always told me to use backup non-hormonal birth control (condoms) when I’m on an antibiotic even for a short time after finishing the prescription.

I used the pill for yrs and was always told to use another form as well when taking antibiotics because it can interfere. Also with some to eat yogurt as it can interfere with the good bacteria in the stomach and cause issues. You can always ask your Dr but best bet is just use other forms of protection for now if your concerned.

Absolutely! They mess with the effectiveness. Just like if you vary on the times you take them can also. I got pregnant with my 2nd child because I switched the time I took my pills because of taking a 3rd shift job.

Yes they do. That’s how I got pregnant on the depo cause my doctor never told me. When I brought it up to her she said “I just assumed everyone knew” it’s okay though cause I’m blessed with a little boy who will be here in about 2-2.5 weeks.

Yes it dose. I had baby number 2 that way. I was off the antibiotics for 2 months. Thought we where go to go but we weren’t.

100% they always recommend an alternative protection during the course of them and up to 7 days after.

No form of birth control is 100% effective. When you hear stories of “I took XYZ antibiotic when I was on birth control and I got prevent” it’s a coincidence. The pregnancy rate in similar populations who conceived while on that same birth control but who weren’t taking XYC is statically the same.

For over 20 years available scientific and pharmacokinetic data do not support the hypothesis that antibiotics (with the exception of rifampin) lower the contraceptive efficacy of oral contraceptives.

You might have heard this myth from your doctor, but anyone who is keeping abreast of research knows this to be false.

Besides, pharmacists are the ones you should be asking about drug to drug interactions. It’s their speciality.

Yes. And it’s recommended to use a secondary form of birth control (condoms) for the duration of the antibiotics as well as for seven days after your last dose of the antibiotics.

The pill it does. Ask your dr which are good with antibiotics.

Yep. That’s how I got child # 2

YES! As far as the birth control pill. Your doctor should have told you that.

I am living proof that they indeed do

Yes that’s how I got pregnant with my first child!

My doctor had always told me to be careful and use a condom with my bc while I took antibiotics just to be safe.

Unless you have the coil IUD, yes it does!

Yes. It even says in the pamphlets for your birth control. And your dr and pharmacist should tell you that you will need to abstain or use condoms to prevent pregnancy while taking and for 7-14 days after stopping the meds depending on which one.

It happened to me. My 38 year old daughter is proof.

Yes! That’s how my birth control failed with my son lol.

They say yes for the pill, definitely ask if your on different kind

Depends on the medication. When you get a prescription filled just ask the pharmacist. I recently got one and the pharmacist told me it will effect it and I’m using a IUD.

Yes some do. I got pregnant with my first born that way. I had no clue antibiotics could do that. Be careful if your unsure about a drug you are taking use extra protection if you don’t want a wee little one :wink:

Yes my daughter was 6 months old and I was on birth control and had an ear infection dr. gave me antibiotic and I got pregnant

Yesssss it does,so if you are on antibiotics I suggest you finish the course & do not have unprotected sex unless you wanna have an unplanned pregnancy

I was blessed with a daughter because of this exact thing. Thank goodness for those antibiotics though!

Obviously, I never needed antibiotics, birth control could have used.

Yes,that’s how I got my fifth grandson, and we love him

Yes. This is how I wound up with my 13 year old

Depends on the antibiotic, and is it not common knowledge to know this? It’s not new information.
