Combination beats misoprostol monotherapy on cost effectiveness

Research is clear, policy needs to catch up

“There is clear research showing that using mifepristone with misoprostol to medically manage early pregnancy loss is significantly more effective than misoprostol alone,” Sarah Prager, MD, of the University of Washington, Seattle, said in an interview. “The combination protocol does include an expensive medication, so it’s important to evaluate if the cost of this more effective method is ‘worth it,’ ” she said. “What this research shows is that, not only does the combination method work better at treating miscarriage, it is also cost effective based on many factors, including fewer projected days off work and fewer patients needing procedures to complete their miscarriage.”

Dr. Prager said she was not surprised by the study findings because similar results have been found in other studies evaluating treatment of abortion with misoprostol alone versus mifepristone and misoprostol. “When something is significantly more effective, it usually will also come with a cost benefit.”

Potential barriers to the use of combination therapy are related to policy rather than drug safety or effectiveness, according to Dr. Prager.

“The primary barrier is that mifepristone use is regulated by a REMS [Risk Evaluation and Mitigation Strategy] restriction which requires that providers dispense the medication directly to patients, rather than being able to prescribe it and have patients then pick it up at a pharmacy,” she said. “This restriction is typically used for medications that are dangerous and need to be closely controlled. In the case of mifepristone, the restriction does not serve a safety purpose; it simply limits access to the medication which is still primarily used to medically treat abortion.

“The secondary barrier is stigma against using a medication that is seen as an abortion medication. I fear many providers or practices may avoid putting it on formulary due to this stigma,” Dr. Prager noted.

“There is already sufficient evidence that the combination therapy is superior to monotherapy, and there is also evidence that mifepristone can be safely prescribed [not dispensed] and does not need the REMS requirement,” Dr. Prager said. “I don’t believe more research is needed; just policy change.”

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Prager had no financial conflicts to disclose.
