You need to ask specifically what his Coccidia count is, because a low count/load is normal and doesn't need to be treated if it's not causing symptoms like diarrhea, lack of appetite, lethargy, etc. Usually they only treat coccidia if the count/load is up in the Moderate to high range, which is where it needs to be to cause any issues in his health and behavior. If the count/load is in the low range, most experienced reptile vets won't treat it at all.
Also, if his coccidia count/load has been and is now again in the moderate/high range and you treated prior with a certain Antiprotozoan medication, you may want to try a different one, because there are different strains of Coccidia, and they aren't all sensitive to the same Antiprotozoan meds.
Toltrazuril has proven to be very effective in beardies as a coccidia treatment, in fact it usually only takes 1 dose, at most 2. It's proven safer and much more effective than Albon, so if he does need another Antiprotozoan medication to treat coccidia and he wasn't given Toltrazuril the last time, I'd highly recommend requesting it from your vet.
