Progestogen-only injectable contraceptive: Experience of women in Osogbo, southwestern Nigeria
Abstract
Background: Progestogen-only injectable contraceptive is a long-acting contraceptive given intramuscularly to give protection against unwanted pregnancy for a period of 2 or 3 months, depending on the type. Alterations in menstrual pattern are a well known side effect of this effective contraceptive method.
Objectives: To determine the characteristics of women accepting the method, complications and indications for discontinuation.
Materials and Methods: This was a retrospective review of clients using progestogen-only injectable contraceptive between 1st January, 2001 and 31st December, 2009. Relevant information extracted from the case notes was analyzed. Survival analysis was carried out using Log-Rank Chi-square test to measure association over 12-month period of usage. Level of significance was set at P value less than 0.05.
Results: A total of 1,967 women used contraception during the study period and 433 (22.1%) made progestogenonly injectable their method of choice. 199(45.96%) used NET-EN, while DMPA was used by234 (54.04%) women. Many of the women (197, 45.5%) used the method for terminal fertility control. Menstrual abnormality was the commonest (264, 71.4%) complaint about progestogen-only injectable contraceptive, of which amenorrhea was experienced by constituted 176(66.7%). Eighty-three (22.4%) women had discontinued the contraceptive, and menstrual abnormality was the commonest reason for the discontinuation (68, 81.9%). No pregnancy was reported among the women that came for follow up while on the method.
Conclusion: Short duration of POIC use that is within 12 months is still high. However the main reason for discontinuation was found to be due to menstrual irregularities, hence the need for effective education of the women about this side effect, thus increasing the acceptance and continuation rate of the contraceptive method.
