Painful periods are common and usually due to uterine cramps, and taking Colimex once or twice a month for relief is generally safe for most women when used as needed and not in excessive doses, with a low risk of long-term side effects. However, if pain is frequent or severe, better-studied options like NSAIDs (such as mefenamic acid or ibuprofen) are often more effective because they directly reduce the cause of pain (prostaglandins). Non-medical measures like using a heating pad, regular exercise, and stress reduction can also help. If your pain is worsening, interfering with daily life, or associated with heavy bleeding or irregular cycles, it is important to consult a doctor to rule out conditions like endometriosis and to choose the most suitable treatment.
