What Experts Say
Mefenamic Acid works by blocking the cyclooxygenase enzymes that produce prostaglandins, the chemicals responsible for pain, swelling, and uterine cramping. Doctors in Pakistan often recommend it for period pain because it addresses the underlying cause of cramping rather than only masking discomfort.
Most physicians advise taking Mefnax with food to protect the stomach lining and limiting use to five to seven days at a time. Longer or repeated use without medical supervision raises the risk of stomach irritation and should be avoided, especially in people with a history of ulcers or acid reflux.
Self medicating with painkillers is common in Pakistani households, but experts caution against combining Mefnax with other NSAIDs like ibuprofen or aspirin without medical advice. Anyone with kidney disease, high blood pressure, or a bleeding disorder should consult a doctor before starting this medicine.
