I had a bad cold this week, it peaked friday, today i have lost my voice, i have got to work monday, should i talk to my doctor about prednisone.

Iffy: If you have a cold, you should focus on rest and hydration. This should include resting your voice. This will increase your chances of having a working voice on monday. The steroids may give you a boost but, it's just a band-aid.

Could.: I would not prescribe Prednisone for loss of voice. It will clear with time. Seems like you are already getting better.
