editing

...more needs to be added re other forms of levo bc/the pharmacology of the progestin, for general article about levornogestrel. recapping mechanism of action for ec is redundancy of ec article/doesn't explain pharmacology of levo in general...

this sentence: "...progestogenic effects, but also has androgenic and estrogenic effects" needs some vocabulary explanation for those of us that didn't go to medical school. Astragal 04:22, 28 August 2006 (UTC)[reply]

hi, i'll wikify them. (people who don't know can then click on links). they're not too complicated --they're the three main hormonal effects of sex hormones. for a good comparison of the relation of progestogenic/androgenic effects in progestins, check out the progestin article. in general, i think this article should look a lot more like ethinylestradiol does (a synthetic estrogen used in birth control).

it looks like all the progestin article are stubs/need a lot of work, and that this one is at least further along than say, norgestrel. hopefully others will pitch in on the whole project, but i will try to add more... Cindery 05:00, 28 August 2006 (UTC)[reply]

persons...

"the FDA in the United States to persons over the age of 18" The FDA Press Release says that Plan B was approved to /women/ over the age of 18 -- "persons" is an incorrect anti-sexism. Jkister

"was approved for over-the-counter sales to persons over the age

 of 18 on August 24, 2006.[1]"

approved where ? (i'm assuming US ?)
also, the [1] footnote seems to be missing

was supposed to be a link to the times article. don't know why it isn't working. don't know how to fix. the full history of the legalization in US, UK, and abroad is in the "Emergency Contraception" article. Will make link to that. -Astragal 16:03, 25 August 2006 (UTC)[reply]

there are no gender restrictions/men can buy it for women, i'm pretty sure... Cindery 04:39, 29 August 2006 (UTC)[reply]

in the UK women can purchase over the counter for own consumpution. It cannot be purcahsed 'on behalf'; therefore men cannot buy in UK

Emergency contraceptive

I looked at this article hoping to figure out the mechanism by which "Plan B" prevents pregnancy. It wasn't here, but I found an explanation from "American Family Physician" here http://www.aafp.org/afp/20001115/2287.html . This seems relevant to the article, since probably a high percentage of people reading it want to find out about Levonorgestrel as an emergency contraceptive. I can add the information myself, but it might be better if someone with a better understanding of medicine did it. Any thoughts or volunteers? Jermor 21:09, 9 April 2007 (UTC)[reply]

More detailed current information on the mechanism of action of levonorgestrel emergency contraception can be found in this March 2007 review by Trussell & Raymond (two recognized experts on emergency contraception): Emergency Contraception.

Apparently there is also a common misconception that Levonorgestrel (aka Plan B) is the same thing as Mifepristone (RU-486). Perhaps this article should contain a statement about this? Jermor 01:39, 23 October 2007 (UTC)[reply]

it most definitely should. I thought it was.65.127.11.162 (talk) 05:25, 9 September 2010 (UTC)[reply]

I don't know if it belongs in the article or not, but that's probably in part due to the fact that in popular culture Plan B has been called an "abortion pill." I can remember at least 2 episodes of TV shows which did this in the last couple of years.OckRaz ^talk 15:26, 30 January 2014 (UTC)[reply]

Not a good source

"In June 2012, a New York Times editorial..."

I don't think it's appropriate to use a NYT editorial under the "Emergency contraception" heading. It's certainly not a scientific source. It seems like an opinion piece by the NYT would be more appropriate under a "controversy" heading or something like that. — Preceding unsigned comment added by 24.14.88.182 (talk) 20:07, 30 August 2013 (UTC)[reply]

I think that's an excellent point. There ought to be a section about how early labeling based on supposition and popular assumptions made many believe it prevented implantation and made LNG EC controversial - but that later research came to the opposite conclusion. The opinion of the NYT editorial board recommending LNG EC is of questionable importance since the editorial board takes a pretty strong pro-choice stand anyway. The fact that pro-life groups who have moral objections to preventing embryo implantation have changed their views is more significant - eg, the Catholic church in Germany approving of it for rape cases.

Commercial use as birth control

This ref says 1980s.[1]

The primary sources shows that it was being studied not that it was commercially approved / used. Doc James (talk · contribs · email) 19:54, 17 April 2018 (UTC)[reply]

This ref says 1983 was commercially introduced [2]

But was first developed in 1966.

Yes as a combination it was introduced earlier. Doc James (talk · contribs · email) 05:28, 18 April 2018 (UTC)[reply]

Peer Review by Michelle Chou

It's a really good article! Sounds professional haha. I think the introduction is a little bit confusing, when you're describing the various birth control methods that Levonorgestrel is part of; I think it's better to list some of the examples all at once, and then explain each one by one, to make it more clear that you're still focusing on Levonorgestrel rather than plan B or the IUD, etc, rather than list one, explain it, and then move on to other examples. The brief section of Countraindications seems unnecessary, unless more will be added on later. I think 'Overdose' could probably be combined with 'Side Effects' or placed somewhere with medical information, because it isn't important enough to be its own subtitled part. I think the 'Chemistry' part could include some commentary that's easier for non-chemists / chemistry students to understand, even just like ("levonorgestrel consists of oxygen, hydrogen, cyclohexane rings, etc.").

Not sure what you mean by "when you're describing the various birth control methods that Levonorgestrel is part of; I think it's better to list some of the examples all at once". It is part of a number of birth control methods. Doc James (talk · contribs · email) 04:29, 5 June 2019 (UTC)[reply]

Linacre Q

This is not an appropriate source. It is not a mainstream medical journal but is published to push a religious POV. Doc James (talk · contribs · email) 04:28, 5 June 2019 (UTC)[reply]

levonorgestrel is in all morning after pills? plan b, is it abortion?

plan b does not allow begotten human emrbio to attach in the uterus:

L- or D-?

I know nothing about chemistry but doesn't the levo- imply that it's an L- molecule not a D- molecule? The sidebar says D-Norgestrel. — Preceding unsigned comment added by 72.74.254.148 (talk) 02:03, 31 January 2021 (UTC)[reply]

Add "Not to be confused" link to Medical abortion article?

It seems like lots of people confuse Plan B with the abortion pills RU486 (Medical abortion). Would it be useful to expand the current note at the top of the page "Not to be confused with.." to include Medical abortion? I'll add that 2nd link to the existing template. If anyone objects, we can remove it and discuss more. Noleander (talk) 02:34, 27 June 2022 (UTC)[reply]
