It's quite strange. I do worry about that medication level even though the ingrediants have been around for years. Not eating since the meds started seems an alarm bell. The fish seem to be quite stressed, more so than I would expect or have seen.
A new tank with new fish is really hard if any infection strikes. About three years ago I had that and lost catfish to the meds. Next time if I used meds on a new tank, I would half dose.
I would keep up water changes (temp match) to remove the meds and also waste organics which would be using O2. The temp matching will mean your fish are not getting a bath of cold water after just getting used to hot and it prevents any cold spots where ich can make a come-back. Otherwise your filtration and everything sounds fine. I would leave temp as it is for another day or so to finish off as you suggested. If the fish were doing better I'd suggest lifting temp a tad to make sure and if I knew the ich was gone I would reduce it. When you do reduce the temp, lower it down gradually as well.
Generally you have to pick a method and stick with it as the fish will be stressed either way. Which is why combining methods is generally not suggested as well. For both methods extra aeration is useful. Have some links on desktop which I will post tonight.
More recently I thought the heat method would be fine over summer as the tank temp was already elevated and the previous summer had a tank temp higher so I knew the fish could adjust. Fish still hated adjusting

Thank you.
