Howdy Matt,
The usual dose of Ponazuril to fight Coccidia in a typical chameleon has been 30mg for each Kg of chameleon weight. So, for example, if your chameleon weighs ~116grams then you'd dose at 3.5mg (which is what is in your 1ml of liquid). Usually a vet will have the pharmacy make the customer a bottle with hundreds of doses diluted to 30 or 60mg/ml (maybe a 100ml bottle) since it still costs less than $30 shipped. 30 or 60mg/ml is a lot more concentrated than your 3.5mg/ml which means that the more concentrated version would be given at fractions of a ml per dose. It works ok either way but with your concentration, they'd be sending you half a pint of liquid for a few hundred doses

. With the higher concentration (lower volume of fluid) it is easier to inject it in a feeder and have your chameleon eat the feeder right away than it is to squirt 1ml into his mouth. Each method has its own benefits but in the end, at least you've got the right drug

.
Don't be discouraged if the Ponazuril doesn't knock the Coccidia completely out in the first round of treatments. It probably will but if it doesn't, the good news is that a 2nd or even a 3rd round of treatments is well tolerated compared to the alternative drugs

. This is where having your own microscope is so handy. You can track every poop to see the progress
