Painkillers for menstrual pain are often non-steroidal anti-inflammatory drugs, such as the common ibuprofen extended-release capsules, diclofenac sodium, indomethacin, etc. However, if these drugs are taken too much, they may cause gastrointestinal discomfort phenomena, such as causing stomach pain, and may also cause gastric ulcers or duodenal ulcers, and in serious cases may lead to gastric perforation. Therefore, long-term use of painkillers is prohibited for women who have stomach problems. In case of primary dysmenorrhea, it is advisable to consult a Chinese medicine practitioner and prescribe herbal medicine for continuous treatment. In the case of secondary dysmenorrhea, the cause of the dysmenorrhea should be identified and treated, such as ovarian chocolate cysts, which may require surgery to remove the cysts.
