I have taken the Depo Provera Jab in Jan before I visited my boyfriend in Canada. Upon returned to SG, I did not continue the quarterly jab. I will be visiting him again sometime in first quarter of 2018. Can I take the jab again? Will I still be protected if I am only taking the jab in an ad-doc basis?
I am 50 yrs old female single.
Appreciate your advice. Thank you
Assuming I understand completely, your last shot was in Jan 2017, before you visited your boyfriend.
Depo Provera is 99% effective at preventing pregnancies for up to 12 – 14 weeks.
I do not know if you had sex 12 weeks after your last shot (ie, from April 2017 onwards). If you did, there’s a chance of pregnancy, and doctors will request for a pregnancy test before restarting you on Depo Provera contraception.
Can I take the jab again?
Yes, you can restart Depo-Provera, but please bear in mind that use for longer than 2 years MAY increase the risk of osteoporosis, and may not be the most suitable contraception option for your requirements.
I’d suggest for you to consult a doctor formally – he will be able to best advise you on the right contraception choice to suit your needs.
Will I still be protected if I am only taking the jab in an ad-doc basis?
If you abstained from April 2017 onwards, then yes, getting the jab before you visit your boyfriend will protect you from pregnancy, for up to 12 weeks afterwards.
Generally the contraceptive effect of Depo-provera will kick in within two weeks of the injection or within 24 hrs if the injection was received during the first five days of your period.
Each injection gives protection against pregnancy which will last about twelve weeks. Yes it can be used at at an interval longer than 3 months ; ie on a “ad-hoc” basis.
Once you are menopausal ( have not had a period for more than 12 months), the likelihood of natural conception is very low and you would not require contraception at that point.
