Period pains: Can anti-inflammatory drugs help?
Anti-inflammatory painkillers like diclofenac, ibuprofen and naproxen can help relieve severe period pain. These medications sometimes have side effects such as stomach problems.
Period pain and cramps (dysmenorrhea) are common. Most girls and women have pain of varying intensity at some point during their period. In some women the pain is so bad that they're unable to carry out their usual daily activities, like going to work or school, on one to three days every month.
In women who have bad period pains, the womb often produces too much of the chemical messenger prostaglandin. This leads to painful cramps in the lower abdomen that might also radiate into the back or thighs. Benign (non-cancerous) growths such as fibroids sometimes play a role too. Very severe period pain can also be a symptom of endometriosis, where the type of tissue that lines the womb grows outside of the womb.
