Personally I would not give meds without a real diagnosis... Vets do things like run a fecal to confirm if there are parasite issues, take blood work to check kidney function, listen to their breathing and inspect the mouth if they suspect a Respiratory Infection. The exam comes first then proof of what is happening to know how to medicate.
Certain meds can be hard on their organ function. So without a real diagnosis based on more then his idea of her symptoms this is pretty absurd to me. You can not visually look at a chameleon and say parasites with most of the parasites that they would carry. Those are microscopic and in the fecal matter.
Might I suggest you fill out the help form So we can make sure that it is not something in your husbandry causing the lack of appetite.
