PIP: 35 predominantly multiparous, sexually active women aged 25-44 years were fitted with levonorgestrel 20 T (Schering) IUDS in the post- menstrual phase, or in rare instances, right after abortion. the devices contained 60 mg of levonorgestrel releasing 20 mcg/day with the life span of 5 years. The patients were followed up every 3-6 months to detect side effects and complications. The first year contained a total of 339 months of observation, while the figure rose to 461 months in the second year. Spotting lasting 15-20 days followed insertion, but in later months only 7% of patients complained of bleeding or menstrual spotting. 7-8% of cases tended to have oligomenorrhea in the first year; 1/3 to 1/2 of them had hypomenorrhea during the first and second year. True amenorrhea started in 20-30% of women, persisting through both years. Longer duration of flow occurred in 32.4-4.57.1% of cases during these 2 years. Hormonal effects (headache, acne, hirsutism, depression, mastalgia, and inflamed varicose veins) ranged from 18.2- 33.3%. Levonorgestrel 20 T demonstrated more superior contraceptive efficacy than Progestasert; however, serious menstrual cycle disorders associated with it also increased. All progestin-releasing devices (the minipill, Norplant, Progestasert) induced menstrual changes, thus their use is preferable for therapeutic indications such as hypermenorrhea and uterine fibroid.
