There is a condition called sterile gut and I would be concerned that you may have this happen using two products that have effects on parasites.
Acidophliz digestive tract condition contains live active bacteria to replace the natural bacteria in a bearded dragons digestive tract that is killed off with the good bacteria when using Albon or other meds that are intended to kill off coccidia or harmful bacteria.
Acidophliz or any acidophilus should be used when medicating bearded dragons with antibiotics (albon is an antibiotic), I think that is one thing that most vets are agreeing on now and I see or get more and more emails from owners and pictures from clinics of their labels on meds now saying this.
Now as far as parazap goes, we have used it successfully to lower a coccidia load or rid it from dragons who were not showing other signs of compromised health from coccida. I would not hesitate to use Albon or other antibiotics if the animals was showing other signs of health problems from coccidia, I just believe in giving they own immune system a chance to deal with the problem with a mad cleaning routine and parazap first if they seem fine otherwise.
