Not taking it because you are worried about having the rash is not being non-compliant.
I am not sure that's what it will turn out to be; I'm trying to remember this for sure but I think the rash nearly always is on the face or chest or is everywhere. I don't remember it being common on extremities so with luck that won't be what you have (but assume it is until proven otherwise or you'll be like me, 7 or 8 years later telling people how you let the rash spread all over and nearly wound up on IV steroids when it wasn't necessary).
How long have you been on it? At 25 mg I assume not too long. I did it my own way; however long the risky period is I did great through that and then 2 weeks after it was over I got the rash. Which is partly why I didn't identify the risk initially although mostly it was denial or just plain not thinking or something else not very smart. I made it even better for myself in having a cold and the only cold med I could take then (and I think now with MAOI restrictions) I had been on for several days and now I'm considered allergic to that med too. So no cold meds at all for me.

And that stuff was new and I'd not had a cold med in several years when I was allowed to take that so it had been exciting.
You can also take benadryl. I wound up on vistaril along with topical steroids and took quite a bit of it for the week I had the rash. I mostly slept through it. I remember what it looked like, that water made it burn and so I took few showers during that time and that it was itchy and that's about all I remember from the time I first saw my family dr for diagnosis (he immediately called my pdoc) and when it got better. I do remember that I got it badly on a Wednesday and worked part of that day which was really convenient because I couldn't work for a week but only missed 3 days (I also hit a holiday weekend).
Just try to not worry too much about it (just worry more than I did

) and it will be fine. I know it's really hard. I just started a 2nd AP and have a history of extrapydramidal syndrome on other meds and this one is an older drug so more risky. The 2nd or 3rd day I got really anxious because I had a lot of muscle pain and hadn't done anything to cause it. It turned out that someone on here told me it was probably from dropping my Seroquel dose and even though it was a tiny drop I think they were right as it was better the next day and then gone. Tomorrow I increase the dose and will go through another few days of being afraid of side effects, even though I have a script for cogentin so that if anything starts I can treat it immediately.
Meds are tough. Necessary sometimes but tough.
