Depo-Provera is most commonly given in the UK and lasts for 13 weeks. Occasionally, Noristerat may be given, which lasts for 8 weeks. Sayana Press also lasts for 13 weeks, but it’s a newer type of injection so is not available at all clinics or GP surgeries. You usually have the Depo-Provera and Noristerat injections in your bottom, but you can have them in your upper arm. You can have the Sayana Press injection in your tummy (abdomen) or thigh and would normally learn to do this yourself.
