Brief summary

The goal of this clinical trial is to determine whether adding vitamin E to mefenamic acid reduces menstrual pain more effectively than mefenamic acid alone in women with primary dysmenorrhea. Primary dysmenorrhea refers to painful menstrual cramps that occur without an underlying pelvic disease. The main question this study aims to answer is: • Does the combination of vitamin E and mefenamic acid reduce menstrual pain more than mefenamic acid alone? Researchers will compare two groups of women aged 15-35 years who experience primary dysmenorrhea. One group will receive mefenamic acid together with vitamin E, while the other group will receive mefenamic acid alone. A total of 60 participants will be enrolled and randomly assigned to one of the two treatment groups. Participants in the combination group will take mefenamic acid 400 mg with vitamin E 400 IU at the start of their menstrual cycle. Participants in the comparison group will take mefenamic acid 400 mg alone at the start of their menstrual cycle. Pain will be measured using a Visual Analogue Scale (VAS), where 0 represents no pain and 10 represents severe pain. Pain scores will be recorded at the time of enrollment and again during the second menstrual cycle after starting treatment. The study will evaluate whether the average pain score during the second menstrual cycle is lower in women who receive vitamin E together with mefenamic acid compared with those who receive mefenamic acid alone. The findings may help determine whether adding vitamin E can improve the management of primary dysmenorrhea.

Interventions

All participants will be given 250 mg of Mefenamic acid (Tablet Ponstan), twice daily, for 5 days: two days before the start of menstruation to three days in menstrual cycle

All participants will be given 200 mg of Vitamin E (Evion capsule), twice daily, for 5 days: two days before the start of menstruation to three days in menstrual cycle
