Uniject as a delivery system for the once-a-month injectable contraceptive Cyclofem in Brazil.
This study assessed the administration of Cyclofem using prefilled Uniject devices. A total of 480 injections were administered divided equally between standard syringes and Uniject. The majority of women (82%) reported that they felt anxious prior to receiving the injection with Uniject. After injection, more than 80% expressed no anxiety about the appearance of Uniject or about the technique of injection. A total of 96.3% of the participants reported slight to no pain with Uniject. In comparison to the standard syringe, 5.6% expressed having had more pain with Uniject. Ninety percent of the service providers reported that Uniject was easy to activate and inject and that it was reassuring for users to know that the syringe and needle had never been used previously. Only two service providers demonstrated difficulties in activating the device. No accidental punctures occurred during the manipulation, and incomplete emptying of the Uniject was not observed. In conclusion, Uniject is a good device for the administration of the injectable contraceptive Cyclofem. It is likely to be appropriate for the delivery of other injectable contraceptives after the necessary stability tests have been performed.
