Research methods – webometric, comparative analyses; systematization of data. As of September 2022, eletriptan, zolmitriptan, rizatriptan, sumatriptan, frovatriptan are registered in Ukraine. The most complete information on the use of sumatriptan is presented in the instructions for «Sumamigren», «Antimigraine-Zdorovya». Summarized information from all the instructions: «The use of sumatriptan is possible only in cases where the expected benefit for the mother exceeds possible risks for the fetus». The information in the instructions for rizatriptan is practically identical for Rizamigren and Rizoptan, and for Rizatriptan-Pharmaten it is presented significantly more succinctly: «During pregnancy, should be used only in case of urgent need». The instructions for zolmitriptan «Zolmigren Spray» indicate: «use of the drug by pregnant women is possible only when the expected therapeutic effect for the woman exceeds the potential risk for the fetus/child».
