Study on Pain Relief Purchases for Period Cramps
A large-scale study analyzing supermarket till receipts has indicated that many women might not be selecting the most effective pain relief medication for period cramps. The research examined a decade's worth of loyalty card data, covering 211 million transactions from an unnamed chain of high street stores in England. It found that paracetamol was the most frequently purchased painkiller alongside tampons and sanitary towels.
However, experts suggest that ibuprofen could be a more suitable option for many women, as it is more effective in addressing muscle cramps associated with menstruation.
Insights from Transaction Data
The transaction data sheds light on the "scale and impact" of period pain and the ways individuals manage it, an area that has been under-researched until now, according to the study's authors. The higher purchase rate of paracetamol may be due to its greater familiarity among consumers.
While paracetamol remains an effective painkiller, ibuprofen is often recommended for period pain because it inhibits the production of prostaglandins—the chemicals responsible for causing the cramping contractions of the uterine muscles.
In contrast, paracetamol primarily acts in the brain to block pain signals, making it effective for headaches and also useful for reducing fever, such as in cases of influenza.
Study Details and Findings
The researchers analyzed purchases made by 3.4 million shoppers between 2006 and 2015. The study, published in the PLoS Digital Health journal, found that half of all transactions involving menstrual products also included a pain relief product. Of these pain relief purchases, approximately two-thirds were paracetamol-based, with the remaining third being ibuprofen.
Co-researcher Dr Anya Skatova from Bristol University emphasized that the data provides a snapshot rather than a fully representative picture of the nation’s buying habits. Nevertheless, it offers valuable insights into what women are purchasing for period pain relief.
Understanding Menstrual Cramps and Prostaglandins
Menstrual cramping is typically a normal part of the menstrual cycle, occurring when the uterine muscles contract to shed the lining during a period. During this process, the body produces hormone-like substances called prostaglandins. Elevated levels of prostaglandins have been associated with more severe menstrual cramps.
Professor James Goulding from Nottingham University, an investigator on the study, highlighted the opportunity for public health education and the lack of research in this field.
"I don't think I'm going out on a limb here by saying that if men got period pain, we'd know a lot more about it by now," he told .
Ibuprofen vs. Paracetamol for Period Pain
Ibuprofen is classified as a non-steroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain, as well as lowering prostaglandin levels. Paracetamol does not possess anti-inflammatory properties.
The charity Endometriosis UK advises that ibuprofen is most effective when taken the day before or several days before the onset of a period or anticipated pain, as this timing helps prevent prostaglandin production.
When to Consult a Doctor
The NHS recommends consulting a doctor if severe period pain interferes with daily activities or causes concern. Such pain may indicate underlying health issues, including endometriosis or fibroids.
Medication Precautions
As with all medications, pain relief tablets can cause side effects. Ibuprofen is not suitable for everyone, and users should carefully read the product information included in packaging before use.
