Norplant, a levonorgestrel contraceptive implant, showed no adverse effects on liver function in Bangladeshi women over two years. This progesterone-based contraceptive appears safe for liver health, unlike combined pills.

Area of Science:

  • Reproductive Health
  • Hepatology
  • Pharmacology

Background:

  • Combined oral contraceptives are associated with adverse liver function.
  • Progesterone-based contraceptives are considered potentially safer for liver health.
  • Norplant (levonorgestrel implant) is a widely used hormonal contraceptive.

Purpose of the Study:

  • To evaluate the effect of Norplant on liver function in reproductive-aged women.
  • To assess potential hepatobiliary changes associated with levonorgestrel implants.

Main Methods:

  • A study involving 149 Bangladeshi women of reproductive age.
  • Liver function tests (LFTs) and hepato-biliary ultrasonography performed pre- and post-implantation.
  • Follow-up period extended up to two years.

Main Results:

  • Non-significant transient increases in serum bilirubin and slight liver enlargement observed in the first year.
  • No significant changes noted in AST, ALT, alkaline phosphatase, total protein, albumin-globulin ratio, or prothrombin time.
  • Overall, liver function remained stable throughout the study period.

Conclusions:

  • Norplant (levonorgestrel implant) demonstrates no adverse effects on liver function.
  • Progesterone-based contraceptives like Norplant are a safe option for women concerned about liver health.
  • The study supports the safety profile of levonorgestrel implants regarding hepatobiliary function.
