Background
Sayana® Press (SP), a subcutaneous formulation of depot medroxyprogesterone acetate (DMPA) in Uniject™, has potential to be a valuable innovation in family planning (FP) because it may overcome logistic and safety challenges in delivering intramuscular DMPA (DMPA IM). However, SP's acceptability is unknown. We measured acceptability of SP among DMPA IM users.

Study design
This open-label observational study was conducted in clinics in three districts in Senegal and community-based distribution services in two districts in Uganda. Experienced DMPA IM users were offered SP by community health workers (CHWs) or clinic-based providers. SP decliners were asked to discuss their reasons. Those who received SP were interviewed pre- and postinjection and 3 months later, when they were asked if they would select SP over DMPA IM if it were available.

Results
One hundred twenty women in Uganda and 242 in Senegal received SP (117 and 240 were followed up, respectively). Nine Ugandan and seven Senegalese SP decliners were interviewed. Three months after receiving SP, 84% [95% confidence interval (CI)=75%–93%] of Ugandan participants and 80% (95% CI=74%–87%) of Senegalese participants said they would select SP over DMPA IM. Main reasons for selecting SP were fewer side effects, liking the method, fast administration, less pain and method effectiveness. Thirty-four adverse events were reported but were not serious. No pregnancies were reported.

Conclusion
Current DMPA IM users in Senegal and Uganda accepted SP, and most preferred SP over DMPA IM. SP can be safely introduced into FP programs and administered by trained CHWs, with expectation of client uptake.

Implications
We found SP acceptable and safe in diverse settings among current intramuscular DMPA users, including those who received SP from CHWs. This provides evidence that SP would be used and could therefore reduce unmet family planning needs if introduced into family planning programs.
