Why This Dysmenorrhea Drug Research Attracted Attention
A recent women’s health story drew wide attention in China: Professor Xiao Ruiping from Peking University spoke publicly about developing a new treatment direction after her daughter suffered severe menstrual pain related to endometriosis.
The investigational drug, HMI-115, has been studied for endometriosis-associated pain and has received breakthrough therapy designation from China’s Center for Drug Evaluation under the National Medical Products Administration. Public research updates report positive phase II clinical results, but the medicine remains an investigational therapy and should not be treated as an available self-care product.
What Is Dysmenorrhea?
Dysmenorrhea means painful menstrual periods. The pain is often felt in the lower abdomen and may spread to the lower back or inner thighs. Some people also experience nausea, vomiting, diarrhea, fatigue, headache, sweating or dizziness during painful periods.
Period pain is common, but severe pain should not be dismissed as “normal.” Pain that stops daily activities, requires repeated medication, or gets worse over time may need medical evaluation.
Primary vs Secondary Dysmenorrhea
| Type | What It Means | Common Features | What to Do |
|---|---|---|---|
| Primary dysmenorrhea | Period pain without an identified pelvic disease | Often starts in the teenage years or early adulthood; usually linked with uterine contractions and prostaglandins | Track symptoms and ask a healthcare provider about suitable pain management if needed |
| Secondary dysmenorrhea | Period pain caused by an underlying condition | May be linked to endometriosis, fibroids, adenomyosis, pelvic infection or other conditions | Medical evaluation is important because treating the cause matters |
Why Does Dysmenorrhea Happen?
Primary dysmenorrhea is often related to prostaglandins, hormone-like substances that help the uterus contract and shed its lining. Higher prostaglandin activity can cause stronger uterine contractions, which may lead to cramping pain.
Secondary dysmenorrhea is different. It is caused by another condition, such as endometriosis or uterine fibroids. In these cases, pain relief alone may not solve the underlying problem, so diagnosis and targeted treatment are important.
Why Endometriosis-Related Pain Needs Attention
Endometriosis happens when tissue similar to the uterine lining grows outside the uterus. It can cause painful periods, chronic pelvic pain, pain during or after sex, heavy periods, fatigue, digestive symptoms around menstruation, and fertility challenges.
Many women live with severe period pain for years before receiving a diagnosis. The public discussion around Professor Xiao’s research is valuable because it reminds families, schools, workplaces and healthcare systems that menstrual pain can be a real medical issue, not just a small inconvenience.
What Is HMI-115?
HMI-115 is an investigational monoclonal antibody targeting the prolactin receptor pathway. It is being studied for endometriosis-associated pain. Public updates from Peking University and Hope Medicine describe phase II clinical research showing improvement in dysmenorrhea scores and non-menstrual pelvic pain scores among participants with endometriosis-associated moderate to severe pain.
These results are encouraging, but more development, regulatory review and approval steps are needed before any new drug becomes widely available. Patients should not attempt to replace medical care with unapproved products or online claims.
How to Relieve Dysmenorrhea Safely
The best approach depends on whether the pain is primary or secondary dysmenorrhea. For primary dysmenorrhea, healthcare providers may recommend nonsteroidal anti-inflammatory drugs, hormonal options, heat therapy, exercise, rest or other approaches depending on the person’s health situation.
For secondary dysmenorrhea, the underlying cause needs to be evaluated. If the cause is endometriosis, fibroids or another condition, treatment may include medication, hormonal management, surgery or other medical plans recommended by a healthcare professional.
| Relief Method | May Help With | Important Reminder |
|---|---|---|
| Heat therapy | Lower abdominal cramps and muscle tension | Use safely and avoid burns |
| Gentle exercise | Tension, mood and general comfort | Choose movement that feels manageable |
| NSAIDs | Prostaglandin-related period cramps | Use according to label or medical advice; not suitable for everyone |
| Medical evaluation | Severe, worsening or unusual pain | Important for possible endometriosis or other causes |
| Cycle tracking | Understanding pain pattern and flow changes | Helpful when explaining symptoms to a doctor |
When Period Pain Should Not Be Ignored
Speak with a healthcare professional if you notice any of the following signs:
- Period pain that stops you from going to school, work or daily activities.
- Pain that becomes worse over time.
- Pain that does not improve with usual self-care or medication advice.
- Very heavy bleeding, large clots or bleeding between periods.
- Pain during or after sex.
- Pain when urinating or having a bowel movement during your period.
- Chronic pelvic pain outside your period.
- Difficulty getting pregnant.
- Fever, unusual discharge, dizziness or severe weakness.
What This Means for Women’s Health Awareness
The public response to HMI-115 shows that women’s pain is finally receiving more attention. Many people who experience dysmenorrhea are told to “drink hot water” or simply endure it. Comfort measures can help some people, but severe menstrual pain deserves real care, medical listening and proper diagnosis.
For families and partners, support can be simple but meaningful: take the pain seriously, help track symptoms, encourage medical evaluation when needed, and avoid dismissive comments.
How Period Care Products Can Support Daily Comfort
Sanitary pads cannot treat dysmenorrhea or endometriosis. However, comfortable period care products can support daily routines during menstruation by improving dryness, softness, breathability and leakage confidence.
Niceday supports period comfort through sanitary pads designed for soft skin contact, breathable structure and reliable absorbency. For brands and distributors, this also highlights a broader market direction: women expect period products that respect comfort, transparency and health awareness.
Frequently Asked Questions
What is dysmenorrhea?
Dysmenorrhea is the medical term for painful menstrual periods. It can include lower abdominal cramps, lower back pain, nausea, fatigue, headache, sweating or other discomfort during menstruation.
What is the difference between primary and secondary dysmenorrhea?
Primary dysmenorrhea is period pain without an identified pelvic disease and is often linked with prostaglandins. Secondary dysmenorrhea is caused by an underlying condition such as endometriosis, fibroids or other pelvic disorders.
Is HMI-115 a general medicine for all period pain?
No. Public research describes HMI-115 as an investigational drug being studied for endometriosis-associated moderate to severe pain. It should not be treated as a general over-the-counter medicine for all menstrual cramps.
Can painkillers help dysmenorrhea?
Some pain relievers, especially NSAIDs, may help primary dysmenorrhea by reducing prostaglandin-related cramping. They are not suitable for everyone, so users should follow medical advice or product labels and seek help for severe or unusual pain.
When should I see a doctor for menstrual cramps?
See a healthcare professional if pain affects daily life, becomes worse over time, does not improve with usual care, comes with very heavy bleeding, bleeding between periods, pain during sex, bowel or urinary pain, or chronic pelvic pain.
Can sanitary pads relieve dysmenorrhea?
No. Sanitary pads cannot treat dysmenorrhea or endometriosis. Comfortable pads may support dryness, softness and leakage confidence during menstruation, but severe period pain requires medical evaluation.
