Background
Emergency contraceptive pills (ECPs) are one of the means by which women can use after intercourse to prevent pregnancy. ECPs can be used to reduce the prevalence of unwanted pregnancies and unsafe abortions. This study investigated awareness and use of ECPs among reproductive age (15-49 years) women in Tamale, Ghana. Factors associated with the use of ECPs were also investigated.

Methods
This cross sectional study was conducted among 200 women of reproductive age (15-49 years) in Tamale, Ghana. Data on socio-demographic variables, awareness and usage of ECPs were assessed by means of a previously validated questionnaire. Univariate and multivariate logistic regression analyses were performed to identify factors associated with the use of ECPs.

Results
Awareness level of ECPs were found to be 69.0% (n = 138); 42.8% (n = 59) got the awareness from a health worker, 31.8% (n = 44) from the radio/TV and 25.4% (n = 35) from family members/friends. Eighty-five percent (n = 117) knew the correct time-frame for an effective use of ECP to prevent pregnancy. Forty percent (39.9%, n = 55) of the participants who had awareness have ever used ECPs. Factors that were found to be associated with the use of ECPs were; participants who said ECPs were affordable (AOR = 6.1, 95% CI = 2.51 – 10.40, p = 0.001), available (AOR 2.1, 95% CI = 0.61 – 6.01, p = 0.001), cultural (AOR = 3.5, 95% CI = 1.01 – 10.15, p = 0.011) and religious unacceptable (AOR = 4.0, 95% CI = 1.02 – 10.0, p = 0.005).

Conclusion
A relatively high level of awareness and usage of ECPs was found. Factors that were associated with the use of ECPs were availability and affordability. Cultural and religious unacceptability did not hinder the use of ECPs. Health authorities should continue to make ECPs available to women of reproductive age.
