This article on Depo Provera Contraceptive Injection explains how it works, who the injection is suitable for, the risks, the side effects, and the advantages and disadvantages of Depo Provera.
What is a Depo Provera injection?
Depo Provera is an injection of progesterone, which is administered every 12 weeks. Progesterone is a female hormone, which occurs as part of the menstrual cycle and pregnancy.
Where and when can you get Depo Provera?
Depo Provera is available from your doctor, your Family Planning Centre or your midwife.
If you have just had a baby, you will be advised to wait 6 weeks before your first injection to reduce the risk of irregular bleeding.
How do Depo Provera injections work?
Depo Provera works by inhibiting, or preventing, ovulation each month. In other words the level of progesterone in the woman’s body prevents her from releasing an egg each month.
The progesterone also changes the lining of the womb, maintaining it as a thin layer, as opposed to the changing thickness that usually occurs during the menstrual cycle. The fertilised egg usually implants when the lining is thick and spongy.
If you receive your first Depo Provera injection within the first 5 days of your menstrual cycle (when your period starts) you will receive instant contraception. If it is later in your cycle then use additional contraception, such as condoms, for the first 7 days.
It is important to have an injection every 12 weeks – some women will get pregnant straight after these 12 weeks, even though for others it would take longer.
How much does Depo Provera cost?
Depo Provera contraceptive injections are available at Family Planning Centres in New Zealand at the following costs –
- The injections are free to women under 22 years.
- For women with a Community Service Card the cost is $5 per injection
- For women over 22, without a Community Service Card, the cost is $22.50 per injection.
Family doctors will also offer Depo Provera injections and prices may vary. Contact your local GP to find out the cost for you.
What is the success rate of Depo Provera?
Depo Provera is very effective in preventing unwanted pregnancy. It is more than 99% effective – so if 100 women use Depo Provera for one year, less than one will fall pregnant.
Depo Provera does NOT prevent sexually transmitted infections or STIs. It is necessary to use a condom also to prevent infection.
What are the risks with Depo Provera?
Depo Provera has been linked to reduced bone density, which is increased in post menopausal women.
This risk is reduced if
- you do not smoke
- you take a healthy diet, rich in calcium
- exercise regularly (e.g. walking or jogging).
What are the pros of these contraceptive injections?
- Depo Provera is suitable for almost all women, unlike contraceptives which combine progesterone with other hormones, namely the combined pill.
- Depo Provera reduces the risk of endometrial cancer – cancer of the lining of the womb.
- It does not interfere with love making
- It lasts 12 weeks
- There is no stress of remembering to take a pill every day.
- Periods are very light; some women get very few periods while they are receiving Depo Provera injections.
- Some women report an improvement in pre menstrual syndrome (PMS).
What are the cons?
- It is not suitable for women with breast cancer.
- It is not suitable for women who may wish to get pregnant in the near future. Depo Provera does not affect your fertility, but it may continue to prevent pregnancy for approximately 6 months after your last injection (and for up to 2 years in some cases).
- Some women experience irregular or prolonged bleeding when they first use Depo Provera. Speak to your doctor about this as this may be relieved by having your next injection sooner, or by taking oral contraceptives also for one month.
Some women experience side effects with hormonal contraception –
- Mood changes
- Weight gain or weight loss
- Decreased sex drive, or libido
- Vaginal dryness
- Headaches

Hi
I have just had my depo last Thursday arfternoon on the 5 of July and I have not had my period for the last ten years. Now I am 20 years old. I had sex for the first time on Sunday the 1st of July. Can I get pregnant when I have been on the depo jab for the last ten years.
Hi Libby, it possibly depends on how long it was before you had your last depo injection. Typically it takes around 6 months for your cycle to return to normal. That said, it’s plausible, and there are some small risks taking depo when you’re pregnant. So you may want to see your GP just in case. — Jarrod
hi, i stopped using this injection in june 2017, 9 mounths now i have not been to my periods. should i be worried?
Hello, I got my first injection the 3rd day of my period cycle here now is the 8th day and I am still bleeding tremendously and normally my period last up into 5days exact. Should I be worried?
Hae am stellah I had my injection on 15 of October last year and it ended on January 15 this year so I decided not to go for another injection.I used the ecp pill after a week from that 15 but I did not receive withdrawal bleeding after a week of taking the pill.could I be pregnant or????Advise me !!!
Hi Stellah. It would be difficult for us to tell, as everyone’s body is different. I’d suggest you try out our free online pregnancy test http://www.kiwifamilies.co.nz/articles/free-online-pregnancy-test/, and perhaps order a pregnancy test kit, or see your local doctor, if you’re still concerned. — Jarrod

Hi there, i got this injection on 10th march and until now i did not have my mensus..is this normal??
Hi,
So I got my first ever depo provera injection and had unprotected sex after four days and not 7 as it’s adviced,particularly because my nurse told me that I’d be safe the 3rd day after the injection. I’m now scared because on googling I see it’s 7 days and not actually 3. What are the chances that I’ve conceived?
Hey Rochelle
I’ve been on the depo shot for two weeks now (as of today )
And I had unprotected sex today….am I protected already ?
Hi Estefania – usually it takes 7 days for the Depo to become effective. Kind regards, Rochelle
I am a British citizen and I’m traveling to NZ on a working holiday visa for a year to two years I have been getting the depo jag for over a year now and I am not sure what I can do when in New Zealand. Is it possible for me to get this here/would it cost/do I need something to get this or prove that I get this back home. The nurses here are unsure and I go away in April!
Hi Sarah, It’s likely that you can just get this from a family doctor or Family Planning clinic. Contraception in New Zealand is heavily subsdised but I’m unsure whether this would apply to you. You could try contacting Family Planning http://www.familyplanning.org.nz/contact and they should be able to offer more advice. Good luck!
Hi. So i had unprotected on the night of my seventh day after the depo, could i get pregnant from this? (First time on the depo by the way).
Hi. Im now 42. Yeah right… first time on this contraception. Always used the pill but its not convenient as sometimes i take it late or forget. So i decided on the injection. Im having my period now for 19 days straight. It was ok at first. But 4 days ago it became less bleeding. But an extreme pain. I did not had sex for about a month now and know im not pregnant due to my busy lifestyle of my career. Was this the wrong decision ay my age? My kids are 22 and 14. I am surely too… Read more »

Hi…I’m hoping someone can help me out here…I have been on depo for about 5 years and came off last month, and since then I have had an IUD put in.

A couple of weeks ago I was in a dark period in my life, the man I love to bits had gone off with someone else, that was when I was told about this Esango Priest. Well he told me he could see that we would get back together that gave me hope, and he was right, because this week we have moved in with each other and are so happy. A big thank you to Esango Priest. If you are in need of an angel please get in touch with my Esango Priest via email:esangopriest@gmail.com
I received the depo shot ( for the first time ever) Monday around 1 and later that day around 5 I started to have extreme lower back pains. It has been continuous since then ( almost 30 hrs) and I’ve tried pain meds. Nothing is working and it’s almost unbearable. Could it be from the shot or maybe something else like a kidney infection? Please help I’d hate to wait this out and it gets worse.
Hi Mercades, Sounds like you really need to visit your GP 🙂
My husband and I have been trying to get pregnant for six years now. We recently have been seeing a fertility specialist. We have done one IUI with no luck. My husband has a sperm count which goes up and down,(the doctor has recomended him taking the Proxeed supplement which he is doing going on the second month now. He also has low motility and morphology. The fertility treatments are already getting so expensive, we may have to stop real soon. The doctor has recomended that we I take injections of HMG to bring on ovalutation, followed by another IUI.… Read more »

Hi I’ve had my period for 4 weeks now. And I’m just wondering if that’s just my body reacting to it or something else?? This is my second time on the jab and I’ve never had my period that bad before? Pls help!?!?
Hi Ladylike, If you’re concerned, the best thing to do is visit your GP or local Family Planning clinic. Good luck!

I have had the depo-provera injection and it expired on 28 August. I have only had the first injection. I am currently trying to plan another baby. Will the injection still continue to prevent pregnancy for approximately 6months – 2years or not as I have only had the one injection?
Hi Danny,
Unfortunately, it’s impossible to say as everyone is different and you never know what else may affect your fertility. Good luck with trying to conceive 🙂

So on Thursday I got my shot but was late getting it. By a couple days did not have sex in those days. but on Friday I had unprotected sex. Then Saturday I have a mucusy blood coming out. And now by.Wednesday I still have it. And I have sharp pains on the bottom left of my stomach where my ovaries are where it kills to walk and cough . Could I be pregnant what is wrong??
I have only had one shot of the depo, my last injection was due july 12th 2013 it is now 4th of august (ino a very short time) but me an my partener are wanting a baby 🙂 We realise we may have to be patient but i started bleeding 4 days after the 12th of july (day my jab ran out) does this mean i may able to become pregnant faster as i bleed straight away? Ive read most women dont start bleeding/spotting for up too 18 months after their last jab.

Been on the needle for 11yrs. Spotted only when I was late getting the nredle. This time I was on time. But she injected me in the back. Next day back aches. Then abdominal pains and back pain together. Spotted for a few days. Should I be worried???
What happens if the nurse injected the depo into the back instead of the butt?
