On the basis of patient's necessity and take of vital analog scale we profile of indometacin suppository in study group and voltaren Amp in control group. Pethedin ampoules were indicated if further necessity were objected. This research was prolonged with 24 hours after operation. Results: In the end after assembling and analyses of information we observed that indomethacin and voltaren both have positive effective on severity of pain after cesarean section (P<0.5), but in comparison with them the voltaren have better effectiveness than indometacin after 4 hours from first dose (p<0.05). There was no difference in two group in necessity by more sedative. But the side effects was lower in study group than control group (P<0.05).
