Yup I know someone who got pregnant using only spermicides. It’s reeeeeally easy to use them wrong. Plus if your partner is not circumcised, the spermicide also kills the friendly bacteria on his penis, which makes it easier for him to get a yeast infection in the foreskin. Not a fan of spermicides as the only method of birth control.

It depends on the pill and the antibiotic. Not every antibiotic renders BC ineffective,  in fact very few do.

@AeroLove:  Hmm…not really sure about the BC and antibiotic thing, but the fact is that no birth control is 100% effective (other than abstinence). When googled, I saw it said that when used properly, it is about 92% effective (which is lower than most other birth controls). Given that you are normally on BC, you might be ok.

In the future, if you find yourself in a similar situation, you might want to consider using condoms for added protection/prevention.

Were you told by your doctor they wouldn’t work? I’d do some research into the antibiotics and BC, and what effect they have on eachother before you panic!

ETA: any idea where in your cycle you are? If not, start tracking things, it helps my keep my mind at ease!

Ah, well, I’m still getting periods, but you could look at temp tracking? Then as long as you’re not unwell, you should be able to tell if you ovulate. I use Period tracker, (app on ipone/ipod) it’s got all sorts of excellent charts for tracking pretty much everything that might be an indicator.

I think it might help to have something to reasuure you. even if it’s not as clear as tracking periods.

You can’t track your cycle on the pill because you don’t have a cycle. If you’re taking the pill correctly, you won’t ovulate.

@AeroLove:  There is only one known antibiotic that renders birth control pills useless. It is a tuburculosis antibiotic called Rifampin. It is the “only” (I use this term loosely because all medications affect people differently) antibiotic that it is heavily advised to use a backup method with. It is a very old wives tale, so you shouldn’t worry too much about antibiotics.

Spermicide, however, when used perfectly has an 8% failure rate. Spermicidal chemicals are not considered to be an effective form of birth control. It is intended and designed to be used with another method (Cervical sponge, male or female condoms, diaphram, etc.) and it is not intended to be used on its own.

About 15 in 100 women per year get pregnant using spermicide – and that’s using it perfectly – when used by itself. It has a very high failure rate when used by itself.

@Hyperventilate:  It’s the only one that has that advice because it’s the only one that’s been thoroughly tested. Thus, they can’t make an accross-the-board suggestion on all types of antibiotics, or even the ones with similar structures/mechanisms of action.

@Hyperventilate:  said,

Spermicide, however, when used perfectly has an 8% failure rate. Spermicidal chemicals are not considered to be an effective form of birth control. It is intended and designed to be used with another method (Cervical sponge, male or female condoms, diaphram, etc.) and it is not intended to be used on its own.

This info is 100% correct.

I know lots of women my age (50s) and older… who “thought” that spermicide alone was a viable contraceptive (jelly, gel, foam etc) … and they have babies / grown children to prove that info WRONG

Used with another method of contraception… like a diaphram… the combined method is very highly rated.

And something that many Drs do recommend, if someone has to give up hormonal BC for any reason (there is “backup” in case a condom breaks etc…)

I myself used it in combo with a Diaphragm for many many years, and only had babies when I chose to

Anyone using condoms only… spermicides is a nice extra precaution for the time of the month when one normally ovulates (a few days either side for insurance)

In your case, I honestly wouldn’t worry to much (I know easier said than done)…

Because, as mentioned… if you are on regular hormonal BC, then the chances of getting pregnant would be low any how, as it would either be totally effective still… or the residual elements would still have you covered most likely.

@AeroLove: BCPills do a combo of things… indeed they stop / alter ovulation… but they also provide an enviroment in the womb that is not friendly to implantation IF ovulation should happen.

I know someone who got pregnant using just spermicide, a few years back.  The FH thought that spermicide only was birth control and was shocked when I told him the rate was about (if used solo) 75-85% and for me not high enought I got an IUD.

The topic ‘Spermicide only?’ is closed to new replies.
