It comes in different forms. I use the 10% paste. You can find it in local feed store or at KV Pet Supply
Fenbendiazole is general dewormer. However, it comes in different concentrations and they need different conversions for reptile dosing. Why do you need a dewormer at this point? Have you performed a fecal? Remember, fenbendiazole does not kill all parasites...
where's website? that one you just recently posted a link right?I would still recommend taking it to get a fecal exam done. For all you know it could have Giardia, Coccidia, or even worse Cryptosporidiosis. Or what if it needs antibiotics?
Here is a website where you can find conversions and diffrent info about diffrent parasite and what drugs are needed to kill them. USE THIS AT YOUR OWN RISK! Scroll past the Parasite table and right below that you will see the conversion for fenbendiazole in blue. Also remember to give your gecko some sort of probiotic while they are on the medication. I would recommend bene-bac bird gel, you can find it on KV Supply's website as well.
I would still recommend you take it to a vet.
Good Luck.
