How to take Postinor 2? Morning After pills

How do u take postinor-2?
According to,
1)Manufacturer leaflet: one Postinor-2 within 72 hours following intercourse and another 12 hours after taking the first pill.2) Martindale reference: levonorgestrel may be given alone by mouth in a single dose of 1.5 mg (2 tablets) within 72 hours of coitus (preferably as soon as possible).
Alternatively, a dose of 750 micrograms (1 tablet) is given within 72 hours of coitus (preferably as soon as possible), and repeated after 12 hours.

3) BNF 53rd Ed Sept 2007: 1.5mg as a single dose as soon as possible (preferably within 12hours but no later than after 72 hours.

Ask the PharmacistDue to popular search, I have decided to answer most of the questions posted by my reader here

1) I would advise them to take as single dose, ie 2 tab at once as soon as possible for increased compliance and to follow the latest advise from British National Formulary. Actually the pills can be taken up to 120 hours after sex, without regard to menstrual cycle, but the efficay reduced as the time pass. The pregnancy rate if taken after one day is 0.4%, 2 days is 1.2% and 3 days is 2.7%.

After u have taken the 2 pills, u may experience menstrual bleeding within one week of the expected time. If u took the pills late into the cycle, your next menses will be prolonged.

2) After u have taken postinor, if u have unprotected sex again, u may become pregnant. So u can take another 2 pills again as the max doses is 4 pills /month.
If u vomited within one hour, take a vomiting pills together with postinor again.

3) The safest unprotected sex is few days before your menses come.
Just use the other methods if u r not sure, ok? Dont understand? Use barrier. DONT UNDERSTAND? USE CONDOM lar ...hehe....

4) Consult a pharmacist if u take any anti convulsant or epileptic medicine such as phenytoin, carbamazepine, and valproic acid etc. Sorry as i wont be replying to the comments here anymore. If you have further questions, pls click like on my facebook account and message me there.

Hi
My husband and I have unprotected sex after being off BC for almost two weeks.
We want to wait at least three months before having our first born being that I've been on BC for almost seven years now

We purchased postinor 2 the very same day and I took both pills as one dosage within 4 hours of having intercourse.

Will this still be effective as taking it 12 hours apart?

Also will this in anyway harm/affect my future pregnancies?


Please advice

What are the chances she would get pregnant?? REPLY ASAP

I had sex last 27 hours,but after sex,I've taken Prostinor 2 after 12 hours,2 pills after meal,I didnt take it 1 by 1..as the pharmacist told me to take it 2 in one go.. But that night after I've taken my pills we masturbated,but no semen contact with vagina. Am I going to be pregnant? How am I going to make sure that the pills worked on me? And if I were to use pregnancy test how soon after sex do I take,the test? And what's the next solution if I'm pregnant? Abortion pills? But any way is it not aborting? it's 27 hours passed by now. HELPP A.S.A.P

Hi! Name is Taylor.
I and my gf use Postinor2 and somewhat trust it but I would like to study it more, hopefully with your help. So far, the only side effect I have noticed is an early OR delayed menses and spotting which mostly do not lead to pregnancy. Are there any other effects? Long term ones?

hi, my friend took postinor2 11 days ago and she felt the cramped and all but the period still have not came around yet. She had unprotected sex on the 12th days and the guy wasnt sure he ejaculated inside or outside. is it safe to take postinor2 again or just wait till the period comes?

Tiger Lilly said...

Hi PharmaLogik,

I had an intercourse a week after my period has done, and in less than 24 hrs I took 2 tabs of Postinor-2. I felt a little bit nausea after that.
I'm so worried of getting pregnant so i took another tablet (one tablet) within 12-hrs after the first two tabs.
Would it affect my chance to be pregnant in the future? I still want to have baby but not at this time

Hi pharmalogik,

I am writing here because i am very nervous and paranoic , i had relations with my girlfriend who she is 20 years old, when he had relations the condom didn't break BUT it stayed their in her vagina at the moment of "detaching" from her but i didnt came unto her i just decided to stop because i was feeling uncomfortable at the moment and well like i said at the moment of detaching from her the condom stayed inside of her , so we got very scared and went to our nearest pharmacy 2 blocks away

she took the pill in 10pm approx - 11pm approx , just an hour of difference.

Additional Information: she has never used one of this pills its her first time.

her period is in February 2 or 3 and all this happen Jan 21,2012

16 hours passed since she took the pill and then she vomited.

the condom contained spermicide

My questions are ..

how effective is all this pill by the info i gave you ?

when can she take a pregnancy test just to be sure ?

can she take any other medicine that has nothing to do with all this, like medicine to help her against the nausea and other side effects? she also takes special vitamins to help against her insomnia problem ...

how long will the side effects last ?

Thanks

maggie said...

hey, i would like to know the effectiveness of postinor if i took it after 36 hours from intercourse and i am on rifampicin. I postponed the time when i usually take rifampicin so that i took it at equal times from the two postinor pills ( i took one pill of postinor, after 6 hours i took rifampicin, and after other 6 hours i took the second postinor pill). Is postinor going to be as effective as written in your post or rifampicin can lower its efficiency seriously?
Thank you

pharmalogik said...

maggie, if you are on rifampicin, i will suggest your partner to use condom. Rifampin can cross over to the placenta and it can cause harm to the fetus. The worse situation is the fetus may get TB too if you are pregnant.

Half life of Rifampin is about 4 hours. that means after 4 hours, 50% of rifampin concentration is still in the blood. after 8 hours, 25% is still there. So your method will not work. The chances of your contraceptive failure is very high.

i would advise you to consult your nearby pharmacist to get a better explanation if you need any.

to my other readers, if you have important questions, pls msg me in facebook by clicking on the link above.

maggie said...

Hello again and thank you for your answer. It seems that you know a lot of things about postinor 2 and its efficiency. Can you tell me please whether it would be better to take both tablets of postinor 2 after unprotected intercourse and the rifampicin eight hours after postinor? Or it would be better to take one tablet of postinor and after 8 hours the rifampicin and the next day (after about 24 hours from the first postinor tablet) the second postinor tablet? ( in order to make everything clear, let's just say that I take the first postinor tablet at 12 am, rifampicin at 8 pm, and the second postinor tablet at 12 am the next day). Would this plan be more effective than taking the tablet as i took it? I am asking you this because maybe this situation will happen again in the future. For now, I can just keep my fingers cross. By the way, we used condom, but it broke. I do not use any regular contraceptive method cause it is inneficient due to the same rifampicin. On the other side, i have chronic TB so the acute stage might come back any time in life. I am asking you this in order to know what to do in the future. Thank you so much for your valuable advices.

to all my readers, please click like on the facebook link above and msg me directly becoz i wont be answering any more replies here on this topic. the comments section here has become too long to manage.

Please read my blog post before asking. question like taking 2 tab asap better or take 1 tablet then another 1 tablet after 12 hours wont be entertained. thank you for your support.
