The data is clear: many women in England are reaching for the wrong remedy to ease their period cramps. A decade-long study of supermarket purchases has revealed that despite expert advice, paracetamol remains a firm favourite among pain relief shoppers – often at the expense of ibuprofen, which is generally considered more effective.
The research, published in PLoS Digital Health, drew on a staggering 211 million transactions from over 3.4 million shoppers between 2006 and 2015. What's striking is that nearly half of all menstrual product purchases were accompanied by a pain relief item – with paracetamol dominating the market at two-thirds to ibuprofen's one-third.
While paracetamol is, of course, an effective painkiller for various ailments, its limitations in tackling period pain are well-documented. Unlike ibuprofen, which works by blocking prostaglandins – the hormone-like substances responsible for muscle contractions during menstruation – paracetamol's primary mechanism of action is to block pain signals in the brain.
Co-researchers from the Universities of Bristol and Nottingham suggest that paracetamol's popularity may stem from its familiarity, rather than a thorough understanding of its limitations. Dr Anya Skatova notes that while the data offers valuable insights into purchasing habits, it provides only a snapshot of the nation. Meanwhile, Professor James Goulding highlights the need for improved public health education on period pain relief – an area that has historically been overlooked.
As always, patients should be aware that ibuprofen may not suit everyone and can have side effects. Reading the product information leaflet before use is crucial. Endometriosis UK advises starting ibuprofen a day or two before a period to pre-empt prostaglandin production – which makes sense, given its anti-inflammatory properties.
It's also worth remembering that severe period pain can be a sign of an underlying condition such as endometriosis or fibroids. If you experience persistent discomfort or disruption to daily life, the NHS recommends consulting your GP for further guidance.
