Allergic reaction (rash) to Repatha or Praluent?

[granbo]

I got a terrible rash after taking it for 5 mos in 2018. Derm called it a "lichenoid drug eruption". (He blamed it on metroprolol. I'd taken that for 10 years with no problem.) Still hasn't completely cleared after stopping it both meds 9 mos ago.Turns out I'm allergic to latex, which a component of the Repatha injector pen. Has anyone had a problem with Praluent? It is not supposed to contain latex. Thank you.

Hello and welcome to the forum. Thanks for your question and sharing your experience.  That is interesting that a rash showed up 10 years into using the medication.  That's a little frustrating.  Here are side effects for Praluent https://www.webmd.com/drugs/2/drug-169420/praluent-pen-subcutaneous/details/list-sideeffects.  Rash is listed as infrequent but it is there.  However, your issue is with latex specifically.  A latex allergy in and of itself is not common with less than 1% of the general population having a latex allergy. It's really important for you to know and inform others of this allergy as about 50% of all medical devices contain latex!  Repatha specifically says to not use if you have a latex allergy but Praluent does not.  I understand your trepidation at this point in using it, but would also trust your doctor to have your best interest in mind and not prescribe something that would presumably cause an allergic reaction for you.  Perhaps they can test it to make sure with a reactive test for you.  https://www.praluent.com/what-is-praluent  Let us know what you decide.  best of health to you.
