Shot (Injectables)

There are two types of birth control shots: the combined shot and the one-hormone shot.

Combined shot

This method is very similar to the combined birth control pills.

The combined shots are a birth control method with a very low failure rate. It is an injection of two different hormones, estrogen and progestin. You have to have this injection every month. It stops your ovaries from releasing an egg, so you can’t get pregnant.

The combined shot is not common in Kenya.

One-hormone shot

The one-hormone shot is a birth control method with a very low failure rate: 4% in typical use and 0.2% in perfect use. It is an injection of just one hormone, progestin. You only have this injection every three months. It works by making the mucus around your cervix thicker so the sperm can’t get through. It can also stop your ovaries from producing an egg.

It’s often sold under the brand name Depo-Provera.


On the shot, your periods generally get lighter, some women even stop having periods altogether. Many women also have fewer period pains. There is a chance that the shot can help with preventing some cancers (endometrial and ovarian cancer).

This method is great for women with sickle cell disease.

Many women experience spotting and irregular periods during the first three months of being on injectables. There is also the risk of a possible increase in depression, anxiety, and other mood changes. Also, quite a few women gain weight while on the shot.

Another disadvantage is that you won’t be able to immediately get pregnant when you stop; it may take around ten months to get back to your normal fertility.

This is also a very private method. If you need to hide that you are on birth control, injectables are a great option.

      Hey Faliza, the Depo-Provera shot has a very low failure rate which means there is a really small chance one could get pregnant. This is why it is encouraged to use atleast two methods at a time to increase the rate of success. For instance, you could include condoms as part of prevention of unplanned pregnancy.

    Hi I took postinor 2 but not immediately after me and my husband had sex then three days later We had unprotected sex could I be pregnant though have already menstrated before all of this event

    1. Hi Joce, thank you for…

      Hi Joce, thank you for reaching out to us. You have asked a great question that is a little complicated to answer. First, if you take Postinor within 72 hours of having unprotected sex then you are within the protection window. However, if you have unprotected sex after taking the pill, you are not under the umbrella of the pill.

      Avoiding pregnancy with unprotected sex needs you to track your period. Your cycle begins on the first day of your period to the first day of your next period.

      To know how long your cycle is, you will need to track it closely for a few months. Most women’s cycle’s last between 28 and 30 days. However, yours may be longer or shorter. Day one through seven are considered to be infertile. Day eight through to day 19 are considered to be your most fertile. From day 20 to the day 26 to 30 are considered to be your infertile days.

      This article should provide more information. Please remember, that using this method can prevent pregnancy but you will still be exposed to STI’s. This method is not full proof and pregnancy could still occur.

    Hai I would like to know am avirgin gal en am 22yrs if I use injection ( shot) for one month what effect would I face

  19. Hi Angel, thank you for…

    Hi Angel, thank you for getting in touch and asking a great question. Whether you use them as a virgin or not, the possible side effects are still the same. Possible side effects of the contraceptive injection:

    • headache
    • abdominal pain
    • weight gain
    • nausea or bloating
    • dizziness
    • acne and other skin problems
    • fluid retention
    • weakness
    • irregular bleeding or spotting 
    • vaginal discharge
    • breast tenderness or pain
    • changes affecting your mood and sex drive
    • thinning of the bones

    In addition, once you stop taking the contraceptive injection, it may take up to a year for your periods and fertility to return to normal.

    The injection is not suitable for everyone and your doctor will have a consultation with you to determine whether you can use it or not. It is not suitable if you, are pregnant, have or have had breast cancer, suffer from vaginal bleeding between periods, have problems with your arteries (including if you have had a heart attack or stroke), have or have had liver cancer or severe liver disease, are allergic to any of the ingredients

    It may not be suitable for you if you suffer from certain other medical conditions so you should always chat with your doctor before starting this.

      Hi Sheila, 

      After about seven days after getting the shot. However, within the first 7 days after the start of your period, you’re protected from pregnancy immediately. Otherwise, you need to use some form of backup birth control e.g. a condom whenever you have sex during the first week after getting the shot.
