I had been doing Liver Flushes for six months before I ever heard of a parasite cleanse. Unless you are very sure that you do have parasites, you should be able to do a successful gallbladder/liver cleanse. In fact I only did my first parasite cleanse two weeks ago using real foods instead of a prepared program (raw pumpkin seeds, garlic, cayenne, and Black-Walnut hulls.) Doing the cleanse had no effect, good or bad, on the results of the liver cleanse. Use your own judgement, you know your body better than anyone.
