Antibiotics effect on birth control

Common Questions and Answers about Antibiotics effect on birth control

antibiotics

Avatar f tn Im not 100 percent sure about the injectitons but I would assume that it can effect your birth control like it does all of the others. Antibiotics have a half life that can temporarily effect birth control, but not permanetly. Ask your doctor for more advise, he/she will be able to tell you immediately.
Avatar f tn I recently had my first depo birth control shot and had to get on antibiotics for a week. How long must I wait to have unprotected sex and not get pregnant?
Avatar n tn My boyfriend and I had unprotected sex mid -month when I would have normally been ovulating but a couple days later I started taking antibiotics. The nurse told me it would void my birth control so we needed to use another method in the mean time. Is it possible that I could still get pregnant from when we had sex before I started the antibiotics now that the pill isn't really that effective for me?
Avatar n tn My girlfriend had been on birth control for about two years. She always had her period on a saturday. Always. She had to stop taking the pills for a month (her prescription was messed up), but once she got her pills back, she didn't wait for her period to start before starting the pills. So my question is, would it be normal for her period to start on a saturday still? Because the period after she started the pills again started on a saturday and lasted for nine days.
Avatar m tn Antibiotics have no effect on condoms, and for even greater protection using a condom correctly during all intercourse while also on birth control pills (which may be less effective while on antibiotics) would offer extremely effective birth control...But still nothing short of complete abstinence is 100% Also, you might look into getting a prescription for topical antibiotic treatment instead of the oral..but the oral antibiotics are probably more effective.
Avatar f tn A lot of antibiotics cause birth control to be ineffective.
Avatar f tn Does antibiotics lessen the effect of depo? What are the chances of getting pregnant while on antibiotics and taking depo?
Avatar f tn zithromycin (z-pack) I DON'T think is known to affect birth control but I'm not 100% on it. I know it has a warning on the indications but all birth controls do...but I've always heard that it was the cillins you had to worry about. Mirena does have the hormones so there may be a slim possibility that it affected it, but have you tested? if you got pregnant during the time you took the antibiotics it would def.
Avatar m tn last month was my first time of using birth control pills. I was expecting my period to come on the first week of March and on the 6th of this month i had spotting. Thought it was the beginning of my period (that would be my first period using pills) but to my surprise it lasted only for 1 day. 2 days later I started taking antibiotics (for cough) for a week . Now is the 23 and still i havnt got my period. What could possibly be the reason? Am I pregnant?
Avatar f tn s always a chance. Doctors always say to use backup protection when taking birth control and antibiotics at the same time.
Avatar f tn So I've been on depo for 9.months now and got my renewal shot and antibiotics for 10 days on the same day, how long should I wait before having unprotected sex? How will they effect eachother????
Avatar n tn yes bc as stated above, z-pac is an antibiotic and when taking them while on birthcontrol, and for some reason when on antibiotics and birth control the antibiotics effect the birthcotrol and don't work i don't if this makes sense or not but i don't know how to put into words for say lol
Avatar f tn ok, one you should know taking antibiotics render the birth control useless while you are taking them,about the other medicines i dont no, but if the doc gave them and he knows you on which birth control then you shouldnt worry,unless you having side effect, try checking on the leaflet that comes with pills, they usually tell you which medicines you shouldnt mix with.
Avatar n tn I was freaked out and thought that the antibiotics may still have an effect on my normal birth control so I bought plan B that week and used protection regularly.. So now, its week three and I didn't use protection.. I have two colored pills left until placebo week and I've been having (un-gas related) cramps... I'm hoping that its from my impending period. I've got my normal breakouts... My mood swings have increased about a MILLION-fold..
Avatar n tn Condoms are not a 100% effective and neither is birth control. I've had 3 friends get pregnant while taking birth control and 1 friend get pregnant using condoms. The odds maybe low but it happens all the time. If you're that worried, then maybe you shouldn't be having intercourse. Oral is always safe (if you don't want a baby).
Avatar n tn I personally have not had this kind of effect from my birth control. Perhaps you should contact your doctor about this and see if a smaller dosage/different contraceptive will help resolve this problem. But when I think on it, I did have a friend with a similar problem as you and she was on bc as well. It could also be a lack of clitoral stimulation. I suggest using a lubricant till the problem can be resolved.
Avatar f tn Also they ask if you are on birth control because antibiotics decrease the effectiveness of oral contraceptives and therefore a second method of birth control is necessary while taking them.
Avatar f tn ( i have to wait more then 10 days as a started my sugar tablets the day i finished the antibiotics). i have only been on birth control for about 2 months. i took my first sugar tablet on friday, last time i got my period on the 3rd day of sugar tablets, it is now the 5th and i havent gotten it. I have only had sex twice after the antibiotics, once using the morning after pill and once using a condom.
Avatar f tn Has anyone conceived while on birth control? I am a mom of one and have been on bc ever since. I was supposed to get my period last week, it never came. I took 2 home pregnancy tests and both came out positive. I never skipped and pill. I was just wondering if this has happened to anyone else.
Avatar f tn Ok.. Thanks. I did went ahead and started my next pack of bcp.
Avatar f tn There is a chance of you being pregnant since Amoxicillan can effect birth control and make it piratically useless. If your boyfriend did not ejaculate inside of you, precum could still potentially make you pregnant however I will say it is HIGHLY unlikely.
Avatar f tn I had no spotting or anything and even tho I was on antibiotics by taking my new pack of birth control I was still able to skip my period with no spotting or anything. So that must mean my birth control had to be working to some degree right? I'm just terrified because I should never have done it, it was a one time thing and if I would become pregnant it wouldn't be a good situation. I have really bad anxiety and about a week ago got back on paxil for it.
Avatar f tn Well im 20 years old and this is the first time ill be on birth control. i tried the pill once when i was younger but i only took em for a month cus i kept forgetting to take them. anyway, i was just wondering.. how many of you have been on the pill and did it work? for how long? what were your side effects? amd how long after you stopped taking them did it take for you to get preggo? just wanting to hear some different storir and points of view.
Avatar n tn I had my son 4 months. And I'm on my birth control called jencycla.it's hormones insteasd of the regular birth control so it wont effect my milk supply I've been on it for 3 months now. The first month my period was normal. The second month I spotted enough to feel up one tampon. And havent had any signs of it so far. Everytime I bf my son I get extremely nauseated. And sometimes I don't have to even be breastfeeding to feel sick. I'm scared I could be pregnant.
