Assessment of client suitability

History

Clinical history taking and examination allow an assessment of medical eligibility for DMPA use. In this context the history should include:

  • medical and drug history
  • family history
  • details of reproductive health and previous contraceptive use.
  • relevant social and sexual history (to assess risk of sexually transmitted infections – STIs)

Risk factors for osteoporosis should be assessed and alternative contraceptive choices discussed as appropriate.


Women should be informed that the efficacy of progestogen-only injectable contraception is not reduced with concurrent use of medication (including antibiotics and liver enzyme-inducing drugs) and the injection intervals do not need to be reduced

Patient self administration of Sayana Press

See procedure for self-administration


Examination

BMI should be noted where possible prior to commencement of the injection. Patient self-reported is adequate.

Administration

Shake syringe vigorously

SC DMPA

Activate the injector according to the manufacturer’s instructions.

  • Inject into upper anterior thigh or abdomen.
  • Point needle downwards (towards the floor) and inject over 5 to 7 seconds.
  • Licensed for self-administration and can be offered routinely by staff trained to instruct patients.
  • See procedure for self administration.

 

IM DMPA

  • IM injection into gluteus maximus or other muscle, e.g. deltoid.
  • IM administration into ventrogluteal site. This is the preferred site as it reduces the risk of superficial injection and sciatic nerve injury.
  • If not yet trained in ventrogluteal injection, or if client requests, the dorsogluteal site (upper outer quadrant of buttock) or deltoid should be used.

Management & timing of first injection
