Breast Feeding Summary
Doxycycline is excreted into breast milk. Oral doxycycline, 200 mg followed after 24 hours by 100 mg, was given to 15 nursing mothers (1). Milk:plasma ratios determined at 3 and 24 hours after the second dose were 0.3 and 0.4, respectively. Mean milk concentrations were 0.77 and 0.38 g/mL.
Theoretically, dental staining and inhibition of bone growth could occur in breast-fed infants whose mothers were consuming doxycycline. However, this theoretical possibility seems remote, because in infants exposed to a closely related antibiotic, tetracycline, serum levels were undetectable (less than 0.05 g/mL) (2). The American Academy of Pediatrics considers tetracycline compatible with breast feeding (3). Three potential problems may exist for the nursing infant even though there are no reports in this regard: modification of bowel flora, direct effects on the infant, and interference with the interpretation of culture results if a fever workup is required.

Questions and Answers
If I get pregnant while taking Doxycycline can it harm the baby? I was put on this and my doctor said to keep trying to get pregnant while on it, is it ok ?
no, the worst it can do is cause tooth discoloration. and that usually happens when you take it during the third trimester. i wouldn't recommend using it for long periods of time. it can cause your hair to fall out.
I am trying to get pregnant, my doctor put me on Doxycycline and said I could keep trying, is that really ok? I started the antibiotic the day after I ovulated, I will be done with it after 10 days of being on it, so implantation would occur around 7 days of being on it, since the pregnancy would be so early on do you think it's ok to take it?
I am sure if your doctor said it is ok then it is. If he knows you are ttc then he would warn you about the side effects on an unborn baby. Best wishes!!!!!!!!
is it okay to take doxycycline hydrochloride if you're pregnant?
No its not. I wanted to take it for medical reasons but my doctor said no its not safe during pregnancy. I suggest you speak to the doc to get an alternative.
Don't take any medications unless you ask the doctor.
doxycycline hyclate does it kill a new born in a pregnant?
It will most likely not kill the fetus but cause serious harm to the fetus.
Pregnancy Category D There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
can doxycycline hyclate harm you if you are pregnant?
YES. You should not take this medication if you are pregnant! It can seriously harm your baby.
Am I pregnant?I had 2 IUI done 2 weeks ago & took Doxycycline & I missed my period? I never ever missed my pe? I missed my perioed ,which never ever ever happens...its always on time or maybe a few days early but NEVER late. I have weird feeling in my stomuch that I never had before. I took the pregnancy test on my second date that I was late and it came out negative?? Could this test be wrong? please help, I need an expert's advice.
It is possible that you are pregnant, but of course you should see a medical professional, regardless of a home pregnancy test's results.
Doxycycline is an antibiotic; most antibiotics will cause estrogen-based daily birth control options (Loestrin, etc.) not to work.
Depending on the sensitivity of the OTC test you used, it could be incorrect. Most, however, are accurate from the time of the missed period. If the test was an "early detection" test (usable up to five days before the missed period), more than likely you are not pregnant. If you took the test a day after your missed period, and then again a couple weeks after, and the results are still negative, you are more than likely not pregnant. False negatives are VERY rare. (Again, GO TO THE DOCTOR!)
Again, go to your doctor as soon as possible. Even if you do not have a health care provider or insurance, Planned Parenthoods or other pregnancy resource centers will provide comfortable atmospheres and accurate pregnancy testing. Definitely choose somewhere you will be comfortable and only go with someone who will be supportive of you in every way. (I advocate non-religious based women's health clinics, because they will give you the most accurate information with the least clouding of any issues.) Counselors can give you honest and non-judgmental advice about what to do if you are pregnant. If you are planning to carry to term, it is essential to get the advice of a medical professional on diet and self-care for every part of your pregnancy.
A few scattered words on pregnancy and menstruation: 1) It is possible to have a period that is late at any age, no matter if you've been as regular as a Swiss watch up until that point. It's possible that if you are somewhat stressed about the possibility of being pregnant, even if it is a welcome pregnancy, that your period will start late. Stress, whether over an exam or relationship or possible pregnancy, has a mean tendency to mess with our monthlies. 2) If this is your first pregnancy, about a month and a half after your last menstrual cycle, you may begin to feel very queasy with so-called 'morning sickness' which unfortunately has free reign to hit you at any time of the day. Ginger ale with real ginger, crackers, almonds, Jell-o, and other bland foods will be your friend during this time.
I hope this was informative. :) Let us know any further informtaion that you'd like to share.
is it possible to get pregnant while you are on birth control? i take doxycycline hyclate for my acne. and im going to get birth control within the next week.
is it possible to become pregnant while on birth control if i am taking that medication?
I also am taking doxycycline (100mg) along with birth control pills. My pharmacist warned me that it will make the birth control pills less effective, so it's a good idea to use a second method, along with the pill.
Keep in mind that any antibiotic is going to make the pill less effective so be careful =)
-EDIT-
Yes, I think it'd definitely be a good idea to use condoms, too...Just to be on the safe side =)
Good luck!
Can I give Doxycycline to a Mommy rat nursing her babies? Here's the story, bought a rat from the pet store, got attached to the little thing only to find out she was pregnant and sick. I've tried over the counter antibiotics--no dice. So I'm looking into this drug. Any advice would be greatly appreciated....Oh, and I'm very apprehensive of taking her to the vet, heard way too many horror stories about vets not really knowing what they're doing with little ratties!
Please hold off giving Doxy to her until I get confirmation from the vets/vet techs on my rat groups. There might be a better way to help her out.
You're right about vets not knowing much about rats, and trying to find one within a reasonable distance is time consuming and next to impossible. But I can guarantee that if you join one of the pet rat-only groups, you will get the help that you need from the rat savvy vets and vet technicians, pharmasists and lab techs, and professional rat keepers, who have joined these groups to help us.

Doxy is a prescription-only drug and needs to be prescribed by a vet who will want to see the rat first.
The following pages have been used to help open-minded vets learn about rats. Close-minded vets continue to ignore our teachings.

Being armed with information and the backing of knowledgeable rat-keepers, before going to the vet, has helped new rat-keepers get what they need from a vet even though they don't know much about rats.
E-mail me privately for more info. spazrats@yahoo.ca There is a lot more info I could provide for you off-list.
Edit:
From a vet tech:
"Use Amoxicillin for pregnant or nursing rat mothers. After weaning, if she is still clinically ill, change to doxy or Baytril or a combination of the two".
From an experienced rat-keeper:
"No, Doxy isn't recommended for a pregnant or nursing mother"
From another tech:
"Doxycycline interferes with bone development. Please
consult vet on
clavamox or other antibiotic. Baytril is not for rats
under 3 mos. of age"
From an experienced rat-keeper:
"No!"
From the Rat Guide:
http://ratguide.com/meds/antimicrobial_a...
"*Note: animal studies indicate that the tetracyclines (Doxy is a family member of these drugs) cross the placenta
and penetrate fetal tissue, as well as being excreted
in breast milk. It is recommended that it not be given in pregnancy or during lactation."
