Hi, I have an outbreak of ich in my aquarium and am using QuICK Cure. Can I use stress coat at the same time?

I spotted some ich in my aquarium yesterday. The affected fish are lethargic and now getting picked on by others ( i keep South American cichlids). Because of this they are even more stressed and have fin damage. I'm in college so I have no quarantine tank. Is it save to use stress coat in conjunction with QuICK Cure or will it harm my fish and/or decrease the effectiveness of the ich medication? (I also have catfish so I'm using a half dose of QuICK Cure)
