I have been receiving Kyprolis infusions on day 1 and day 15, and a Dara Faspro injection on day 15 of treatment for the past three and a half years. On Thursday of last week I received both Kyprolis and Dara. Three days after the treatment I woke up with a severe case of hives. This has not happened previously. I do take Claritin the day before, day of, and day after treatment and 4 mg. of Dex the day of treatment. Has anyone experienced this?
