I have the same problem, usually i just took normal painkillers (ibuprofen and paracetamol) but they weren't really working, so i asked my doctor yesterday and he's prescribed me some different type of painkillers specifically for period pain (Mefenamic), he told me it's an ibuprofen based painkiller but there's other ingredients in it that help with period pains.
I'm not sure if you can buy it over the counter, but if your girlfriend (or you) go into a pharmacy or chemist and ask if they have anything for it they should be able to recommend something for her with you having to go to the doctor.
It also helps if you taking painkillers leading up to your period as that can stop the pain she could get before had (i know i do), and also it's already kind of left in her system so would stop the actual period pain being so bad.
Hope that helps.
