Can phenacetin-caffeine tablets treat dysmenorrhea?

In general, phenacetin-caffeine tablets can help relieve pain caused by primary dysmenorrhea. However, if the dysmenorrhea is secondary (due to underlying diseases) or accompanied by severe pain and abnormal symptoms, using phenacetin-caffeine tablets alone may not provide a cure and could pose health risks. If in doubt, it is advisable to consult a healthcare professional in advance. Detailed analysis is as follows:

If the dysmenorrhea is primary (without organic pelvic lesions, mostly caused by elevated prostaglandin levels) and the pain is mild to moderate, taking phenacetin-caffeine tablets can inhibit prostaglandin synthesis and alleviate pain, temporarily improving menstrual discomfort such as abdominal cramps and lower back pain, thereby helping maintain normal daily activities. However, the dosage should strictly follow the instructions to avoid exceeding the recommended amount, which could increase the burden on the body.

If the dysmenorrhea is secondary (caused by conditions such as endometriosis or uterine fibroids), or if the pain is severe and accompanied by abnormally heavy menstrual bleeding, fever, or other symptoms, phenacetin-caffeine tablets can only provide temporary pain relief and do not address the underlying cause. Moreover, they may mask the condition and delay proper diagnosis and treatment. In such cases, the root cause must be identified first, followed by targeted medical intervention. Relying solely on this medication may worsen health risks.

Before taking phenacetin-caffeine tablets for dysmenorrhea, ensure there is no history of drug allergy or severe liver or kidney dysfunction. Continuous use should not exceed three days. If pain persists or worsens, seek medical attention promptly.
