I know it says wait 24 hours til you Do a water change can you do it a few hours earlier or a few hours later or can something happen ?

I like you might get a few different views. I think it’s ok. I personally would but  a few hours late. @Columight have a better view.

I would follow the instructions on the box personal if I use levamisole I add it to food and feed for 7 days using this recipe

So better off letting it stay in the tank longer

Levamisole likely does most of what it’s going to do within the first hour it’s in the tank.  Timing of the water change is unlikely to be an issue as long as you wait at least 12 hours after dosing but closer to 24 is much better.  You want the fish to have time to expel the worms before you do your water change so they will be siphoned out with the water change.  Getting the meds into the food is even better than dosing in water, but not all fish will eat the medicated food (pea puffers just scoff at prepared foods and give you “the eye”).

Praziquantal (PraziPro) is definitely best left in the water and the directions on the package reflect that.
