1  | BACKGROUND

In 2012, the International Federation of Obstetrics andGynecology(FIGO)producedachartdetailingrecommendeddos-agesofmisoprostolwhenusedalone,foravarietyofgynecologicandobstetricindications.Inlightofnewevidence1–13andthroughexpertdeliberation,thischarthasnowbeenrevisedandexpanded(Fig.1).Someareaswereparticularlychallengingtodevelopgiventhe limited, low-quality, or inconsistent evidence. The presentcommentaryisintendedtoexplainsomeofthechangesanddeci-sionsmade.

2  | GENERAL CHANGES

Thelayoutisnowcategorizedverticallybygestationandhorizontallyby indication.Gestation is labelledandreferredtoasthenumberofweeksofgestation (<13weeks,13–26weeks, and>26weeks),withthefinal columnbeing forpostpartumuse.However, in the caseofincompleteabortionunder13weeks,andinevitableabortionbetween13–26weeks,womenshouldbetreatedonthebasisoftheiruterinesizeratherthanlastmenstrualperioddating.Recommendationshavebeenaddedforinevitableabortionandcervicalpreparationbetween

13 and 26weeks, and for termination of pregnancy at more than26weeks.

thatcompleteexpulsioncanbesafelyachievedbycontinuingtheregi-menupto72hours,withoutcompromisingthewoman’ssafety.9

4  | ROUTE OF ADMINISTRATION

Given recently published evidence,2–9 we have added alternativeroutes for taking misoprostol; in most cases, this has meant theadditionofthebuccalroute,inwhichthetabletsareplacedinthecheekfor30minutesafterwhichanyremnantsareswallowed.Thisroute has a similar pharmacokinetic profile to the vaginal route.Furtherongoingstudiesareindicatingthistobeapromisingrouteforother indicationson the chart, but these indicationshavenotbeen included because data on efficacy have not been reported.Future studies will continue to provide evidence on what mightbe a variety of effective regimens and routes of administration.Althoughthiscouldresultinseveralavailableoptionsforproviders,it will also enable women’s preferences to be taken into consid-eration.Women’spreferences canvary,with somepreferring thevaginalroute(ifinsertingthepillsthemselves)andsomepreferringnon-vaginalroutes.However,thevaginalrouteshouldbeavoidedwhenthereisbleedingand/orsignsofinfection.Thechartdoesnotinclude the rectal route.We recommend against using this routebecausethepharmacokineticprofileisnotassociatedwiththebestefficacy.

5  | MISOPROSTOL USE IN PREGNANCIES WITH PREVIOUS CESAREAN OR TRANSMURAL UTERINE SCAR

The use of misoprostol at 13–26weeks’ gestation in women withpreviouscesareanortransmuraluterinescarwasdebatedbecauseofconcernsaboutan increasedriskofuterinerupture.Forfetaldeath,aCochranemeta-analysis15reportedmixedfindings,concludingthatthedatawereinsufficienttoassesstheoccurrenceofuterinerupture.Afewstudieshavereportednoincreasedlikelihoodofrupture,16 but oftenwomenwithpriorcesareanoruterinesurgeryareexcludedfromstudiesorreviews,ortrialsareinsufficientlypoweredtodetectadif-ferenceinsafetyoutcomesasaresultoftherarityofmajoradverseevents.Thereissomeevidencethat,forterminationsinthisperiod,theriskofuterineruptureamongwomenwithapriorcesareandeliveryusingmisoprostolislessthan0.3%1,17;otherstudies9,18–20concludedthattherearenosignificantdifferencesinoutcomesforwomenwithpreviouscesarean(s).Wethereforeconcludedthatmisoprostolcanbeusedforwomenwithpreviouscesareanorothertransmuraluterinescarthroughout13–26weeks.

Thereisinsufficientevidenceavailabletorecommendaregimenofmisoprostolforuseatmorethan26weeks’gestationinwomenwho have had a previous cesarean or transmural uterine scar.Therefore,withoutevidencetosupportasaferegimen,wedonotprovide one, other than to recommend following local protocol inthesecases.

6  | MANAGEMENT OF PREGNANCY TERMINATION AND FETAL DEATH OVER 26 WEEKS’ GESTATION

Althoughthere issomeevidencetosupportadecreasingdosewithincreasinggestationalage,thereislittleevidencetosupporttheadvicegiven in some international and national clinical guidelines to uselowerdosesofmisoprostolincasesoffetaldeath.Irrespectiveoftheissueofrecommendationsfordifferentdoses,variousreviews15,20,21 haveconcludedthatthereisinsufficientevidenceoverallofsuperior-ity of onedoseor schedule ofmisoprostol over another for use inpregnancies at or over 13weeks’ gestation. In making recommen-dations,weacknowledged thatprovidersmightbekeen to identifylowestpossibledosesbecauseofreducedadverseeffects,21butthatitwasalsoimportanttoconsidersuccessratesandtimetodelivery:lowdoseshavebeenshowntobeassociatedwithalongerinduction-to-delivery interval and lower overall effectiveness,15,21 and evi-dencehassupportedthesafetyofthe“higher”dosesforwomen.7–9 Recommendationsinthechartwerecompiledwiththisinmind,whilealsoacknowledgingthatitispossiblethatarangeofdosagescouldbeeffectiveandsafe.

7  | RETAINED PLACENTA

Therehavebeentwostudiesoftheuseofmisoprostolforthetreat-mentofretainedplacentafollowinglivebirth,neitherofwhichshowany benefit over placebo.22We therefore do not recommendmis-oprostolforretainedplacentainlatepregnancy.

8  | SECONDARY PREVENTION OF POSTPARTUM HEMORRHAGE FOR COMMUNITY- BASED PROGRAMS

Secondaryprevention isacommunity-basedstrategy thathasbeenshown to be a comparable alternative to a universal prophylaxisapproachintwolargecommunitytrials(oneinpress).12Ratherthanmedicatingallwomenduringthethirdstageoflaborwithaprophy-lacticdose,aregimenof800μgsublingualmisoprostol(thesameasfor treatment) can be used to treat onlywomenwith higher-than-averagebleeding(e.g.approximately350mLormore).Althoughthereislimitedpublisheddata,itwasagreedthatsecondarypreventionofPPHisastrongalternativeapproachtouniversalprophylaxis,becauseit involves medicating far fewer women (5%–10% vs 100%), thuscausingfeweradverseeffectsandreducingcosts.
