medication

[lost fish]

Any advice as to what kind of medication I can use on a newly purchased fish before introducing him into the main? I am new at this hobby and just lost all my fish to ick because I did not quarantine, I assume. I have read that a newly purchased fish should be in a QT tank before placing him the main. Should I medicate for prevention? If so what should I use? Also, are cleaner shrimp valuable to combat this disease?
Thanks for any advice!
