[Prevention and treatment of intrauterine device caused abnormal menstruation by huan-an powder].

Huan-an Powder (HA) was used to prevent and treat the intrauterine device (IUD) caused abnormal menstruation in 155 cases, who were divided into the prevention group and treatment group. In the former, 70 cases had taken the powder, resulting in no obvious difference in their amounts of menstrual blood, menstrual period, menstrual cycle and hemoglobin between after and before the applying of IUD (P > 0.05). In the latter, there were 85 cases, of whom, 30 with hypermenorrhea, 30 with menostaxis, and 25 with preceded menstrual cycle, the total effective rate was 90%, 93% and 88% respectively. After HA was used, the amount of the menstrual blood was significantly reduced, the menstrual period markedly shortened (P < 0.01), while the menstrual cycle was prolonged and hemoglobin increased significantly (P < 0.01). The results showed that HA is a good recipe in preventing and treating abnormal menstruation caused by applying IUD, with highly effective and safe, and without any side effects and contraindications.
