Flukicides are mainly never for milking animals, it can be really tough.
Albendazole and oxyclozanide i believe are your best options, with milk withdrawals listed for cattle that can be applied to goats, triclabendazole only comes in one formulation for milking animals which is i believe fasinex 240 but still has i think a 60 day milk withdrawal.
Then you can use another wormer for roundworms if required, i use eprinex which has 0 milk withdrawal.
Talk to your vet about the need for flukicide or round wormer as combinex does both and they may be able to let you know if you're actually not a risk area for fluke, or if resistance to roundwormer is low, you may be able to just use albendazole if there isn't white wormer resistance.
It is tough as vet school doesn't teach us much about either goats or wormers, let alone those with milk withdrawal periods suitable for goats!
