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