Painful menstruation, also known as dysmenorrhea, is a common problem affecting a significant percentage of women. In the United States and Europe, nonsteroidal anti-inflammatory drugs (NSAIDs) and oral contraceptives are the most commonly prescribed treatments for this condition. However, in China, oral contraceptives are not commonly prescribed for unmarried women. Acu-injection, a procedure involving the injection of vitamin K into acupuncture points, has become standard treatment for dysmenorrhea at many Chinese health care facilities. This trial will assess the willingness of young Chinese women to participate in an acu-injection trial, explore the utility of pain measurements after injection, and determine the effectiveness of the injections. This study will also help in planning larger acu-injection clinical trials.
This study will last for five menstrual cycles. Participants will be randomly assigned to one of three groups. Group 1 participants will receive a vitamin K3 injection in an acupuncture point of both legs and a saline injection in the right buttock. Group 2 participants will receive a saline injection in an acupuncture point of both legs and a saline injection in the right buttock. Group 3 participants will receive a saline injection in a pseudo-acupuncture point of both legs and a vitamin K3 injection in the right buttock. Injections will be administered one time during the first 2 days of the first menstrual cycle for participants who are experiencing menstrual pain. Participants will record their level of menstrual pain before injection and at 2, 5, 30 and 60 minutes after the injections. Participants who do not respond to or are not satisfied with the acu-injection treatment will be offered either Chinese herbal medicine or NSAIDs within 1 hour of the injection. After the injection visit, participants will be asked to complete questionnaires about any menstrual pain or side effects they may be experiencing for five subsequent menstrual cycles.
