Efficacy Study of Prophylactic Ibuprofen Versus Placebo on Pain Relief and Success Rates of Medical Abortion

February 15, 2012 updated by: Prof. Daniel Seidman, Sheba Medical Center

The Effect of Prophylactic Ibuprofen Versus Placebo on Pain Relief and Success Rates of Medical Abortion: A Double-blind Randomized Placebo Controlled Study

In the current study, we want to evaluate the prophylactic use of ibuprofen versus a placebo for medical abortion by mifepristone and misoprostol, at a gestational age of up to 7 weeks, in regard to the effect on pain relief and the overall procedure success.

expected results:

The prophylactic use of NSAIDs could offer significant pain relief and thereby a reduction in the need for additional pain relievers compared to the placebo, without interfering with the outcome of medical abortion

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ibuprofen
the group will receive 2 tablets of ibuprofen 400 mg at the time of misoprostol administration. The information about the effect of the analgesics on the pain, and on the course of medical abortion, will be prospectively gathered from questionnaires completed by the study participants
Drug: ibuprofen
The most common side effect observed during medical abortion using mifepristone together with misoprostol is abdominal pain. The use of ibuprofen was not shown to interfere with the action of misoprostol to induce uterine contractions and pregnancy expulsion.
Other Names:
  • ibuprofen - Nonsteroidal anti-inflammatory drugs (NSAIDs)
No Intervention: placebo
this group will receive 2 placebo tablets together with the misoprostol

Secondary Outcome Measures

Outcome Measure
Time Frame
• Success of medical abortion as assessed by follow-up ultrasound examination and the frequency of surgical intervention was recorded.
