How long should i take prednisone for my poison ivy? doc said 2 weeks, this seems a tad long???

Poison ivy sucks: I would follow your docs instructions. Poison ivy can be pesky to treat and the oils that cause reaction tend to spread to other parts of the body. 2 weeks prednisone shouldn't cause any long term complications in the grand picture of things, as long as it isn't a regular thing.

Depends: If your skin lesions have cleared and you have cleaned out all of the articles which have been in contact in poison oak, you may consider stopping the prednisone. On the other hand, a 2-wk course of prednisone is unlikely to cause you any harm other than perhaps some weight gain.
