Background: Hormonal contraceptive use can be a trigger to altered levels of haemoglobin in
reproductive age group women leading to anaemia. The objective of this study was to evaluate levels of
haemoglobin in women of reproductive age using hormonal contraceptives. Methods: It was a case
control study conducted in Family Health Hospital, Johar Town, Lahore. The study group women
attending the Family Planning Unit were using low dose COC pills, Depomedroxyprogesterone acetate
(DMPA) 3-monthly injection, or Norethisterone-enanthate (NET-EN) 2-monthly injections. Blood
samples were obtained and haematological tests were run on the samples. Results: Tests revealed that
women using injectable hormonal contraceptives were more prone to decreased haemoglobin levels
after prolonged use as compared to those using COC pills. Conclusion: Long term use of progestin
only injections can lead to anaemia as compared to COC pills in women of reproductive age group.
