Dysmenorrhea (Menstrual Cramps)
Dysmenorrhea is painful menstrual cramping in the lower abdomen that occurs before or during a period. It's extremely common and very treatable, and can be assessed confidentially without an in-person exam in uncomplicated cases.
Could It Be Dysmenorrhea?
- Cramping or throbbing pain in the lower abdomen, typically starting just before or at the onset of a period
- Pain that comes in waves and eases as the period progresses (usually resolving within 2–3 days)
- Dull, constant ache that radiates to the lower back or thighs
- Nausea, fatigue, headache, or loose stools alongside cramps
- A predictable pattern that occurs with most menstrual cycles
- Pain that's manageable with rest or over-the-counter pain relief, though sometimes severe enough to disrupt daily activities
Treatment
- Prescription-strength NSAIDs (naproxen, mefenamic acid, ibuprofen, diclofenac, ketoprofen, flurbiprofen, celecoxib, ASA) to reduce prostaglandins that drive cramping and pain
- Guidance on timing doses (starting at first sign of period or cramping, and continuing on a scheduled basis) for best relief
- Advice on heat therapy, exercise, and lifestyle measures to complement medication
- Ontario pharmacists can assess and prescribe directly for uncomplicated primary dysmenorrhea

Frequently Asked Questions.
What causes dysmenorrhea?
Prostaglandins released by the uterine lining cause the uterus to contract, which reduces blood flow and triggers cramping pain. Primary dysmenorrhea has no underlying condition; secondary dysmenorrhea is linked to conditions like endometriosis or fibroids.
How is dysmenorrhea treated?
NSAIDs are first-line treatment, working by reducing the prostaglandins that cause cramping. Ontario’s minor ailments program allows pharmacists to assess and prescribe prescription-strength NSAIDs directly for uncomplicated cases.
How long until symptoms improve?
NSAIDs typically start relieving pain within 30 to 60 minutes when taken at the first sign of cramping, with cycle-to-cycle improvement often noticed once dosing is started early and taken consistently through the first 2–3 days of the period.
Is period pain always normal?
Mild to moderate cramping is common, but pain that’s severe, worsening over time, or not relieved by standard NSAID doses may point to an underlying condition such as endometriosis, adenomyosis, or fibroids, which is why symptom pattern and history are reviewed as part of the assessment.
Are there other causes of pelvic pain I should be aware of?
Yes, conditions like ovarian cysts, pelvic inflammatory disease, or endometriosis can cause similar pain, which is why timing, severity, and associated symptoms are always reviewed before confirming primary dysmenorrhea.
When should I seek in-person care instead?
Seek in-person care for pain that doesn’t improve with prescription-strength NSAIDs, pain that’s new, worsening, or different from your usual pattern, heavy bleeding or blood clots, pain outside of your period, fever, or symptoms suggesting pregnancy or another gynecological condition.
