Yes you can use liquid dewormers on freeze dried & flake foods, however they aren't that good when mixed with flake. Freeze dried or frozen (but defrosted and with the liquid drained off) is better than flake.
Flake food absorbs the liquid medication quickly and easily but also loses it quickly when put in the aquarium water. So if it isn't eaten instantly, there is a chance the medication can leach into the water and the fish don't get treated. The bulkier food like freeze dried bloodworms or frozen (but defrosted & drained) bloodworms hold the medication for longer when they are in the tank water, so there is more chance of the fish eating the medication on the food.
---------------------
Liquid dewormers are not always as good as the dry tablet form because the liquid breaks down the active ingredient quicker and they need to add preservatives to keep the Praziquantel viable. And if the liquid medication is kept warm it will break down faster than if kept in a cool environment. The best place for medications and test kits is in a cool dry place. I kept mine in a plastic icecream bucket in the bottom of the fridge.
*NB* Make sure children and animals cannot get the medications or chemicals/ test kits because most of them are poisonous. Praziquantel is pretty safe tho.
The same with test kits and any medications be they liquid or dry. Heat destroys them so check the expiry date before buying them and make sure they are not being kept in a fish room or near a heat source or in a warm area. On a shelf in an air conditioned shop is fine but if the medication is sitting on a window sill or next to a refrigerator and the air around the product feels warm, it might be stuffed.
