I have had excellent results with 2 treatments for ich in puffers.
Hybrid TTM and Coppersafe.
Coppersafe seems to be the least harsh when treating puffers using copper. But you need to keep it at theraputic levels and need to make sure it stays there. Testing needs to be done with something like a hanna copper or a decent sopper test kit. You also have to watch ammonia very closely. Puffers, once eating, are waste producing machines.
Hybrid TTM is a lot of work, but works well and puffers do not seem to stressed when swapped from tank to tank like other fish. It does require h202 baths in between the transfers though. ALso, ammonia is not as much of an issue, as the fish gets new water each transfer. The down side is 2 tanks to do it, must wash and disinfect old tank after transfer and make sure not to cross contaminate from tank to tank. This is made a little easier, for cross contamination, as there are dips in between the transfers. This is now my preferred method for treatment of puffers, as there is no copper to suppress appetite.
Both methods mentioned above are easy to find via search or a sticky in the fish disease section of this forum.
