Key points

  • Period pain is very common but shouldn't stop you living your life.
  • First line: NSAIDs (ibuprofen, naproxen, mefenamic acid) — start before pain peaks.
  • Heavy periods may need tranexamic acid or hormonal treatment.
  • Endometriosis or fibroids cause severe pain — investigate if not responding.
  • An online GP can prescribe stronger options.

Self-care

  • Heat (hot water bottle, heat pads).
  • Gentle exercise.
  • Ibuprofen 400 mg every 6 hours — most effective started before pain peaks.
  • Tracking cycle and symptoms helps identify patterns.

Prescription options

  • Mefenamic acid 500 mg three times daily during periods.
  • Tranexamic acid 1 g three times daily for heavy periods.
  • Combined contraceptive pill — reduces pain and lightens periods.
  • Mirena IUD — significantly reduces pain and bleeding.
  • Investigation for endometriosis if severe.
