No, low to moderate levels of either Coccidia or Pinworms should not be treated at all, as #1) Most all bearded dragons live with low levels of both in their GI tracts throughout their entire lives with no issues at all, and #2) The medications to treat both of these causes far more issues than the low to moderate levels of either Coccidia or Pinworms do.
I've had the same Certified Reptile Vet for almost 15 years and he only ever treats either Coccidia or Pinworms if they are found to be in either "High" or "Too numerous to count" loads/counts, or if the dragon is exhibiting signs that the Coccidia or Pinworms are causing them grief, mainly lowering their appetites or causing great lethargy. Otherwise you should NEVER treat low to moderate levels of Coccidia or Pinworms, it causes more harm than good. In fact, if you were to do a fecal test (either a gram stain or just a fecal float) on any number of randomly chosen, healthy, active bearded dragons, most if not all of them would test positive for low to moderate levels of Coccidia or Pinworms. This also goes for most species of reptiles and amphibians. Now if there are different types of parasites detected in even low counts, like other types of worms, protozoa, bacteria, etc. that are not normally found in the GI tracts of reptiles, then they may need to be treated immediately because they are not supposed to be there and any amount of them may cause illness. But as far as Coccidia and Pinworms go, they should never be treated if they are found in low to moderate counts or unless they are causing severe appetite loss or lethargy.
