What treatment for neuropathic itch from chemo worked for you?

After my 1st infusions, (carboplatin, taxol, keytruda), I experienced itching in my hands and feet, it worsened after the 2nd infusion. Antihistamines / steroid creams do not work. The oncologist does not want to reduce my dose until I complete a round of gabapentin to see if that masks the itching.
The itch is so severe it is debilitating. Showering is out for me as water activates the itch which lasts around 4 hrs.
The oncology nurse said the neuropathy usually goes away within 3 months once the infusion series is completed. I think she is talking about peripheral neuropathy where you get numbness and tingling.
I am stage 4B so really need the chemo drugs to knock the cancer back but am wondering if I am left with this side effect the whole process was probably not worth it.
Anyone found an effective treatment for this condition?
