If a remedy that clearly helped is now making things worse, the problem may be how often it is being given rather than which one was chosen.
In true classical homeopathy a remedy is given as a single dose, and then you wait — often weeks — repeating only when the picture clearly relapses.
Some practitioners, sometimes described as "modern classical," dose far more frequently — daily or several times a day. For a sensitive child that difference matters a great deal.
So a child given a remedy known for rage and biting, daily for weeks, can develop more rage and more biting — and it is indistinguishable from the illness getting worse. Families then increase the remedy, which deepens the problem.
When a well-chosen remedy acts but does not last, classical practice looks for a maintaining cause — something actively regenerating the picture faster than the remedy resolves it. In a PANS child that is very often an untreated infection or exposure.
That is worth knowing, because it reframes the problem: the remedy is not failing. It is being asked to hold against a fire nobody has put out.
These are questions for your homeopath, not reasons to stop on your own — but they are fair questions to raise.
Want this answered for your own child? A Plan B synthesis reads every lab and note you have — together — and tells you what is driving the picture, what has never been checked, and what to ask for next.
The first one is free, and you keep the list either way. Phone photos of labs are fine.
Plan B for PANS is written by a parent, not a physician. Nothing here is medical advice or a substitute for your child's clinicians — it is meant to make you the best-informed person in the room when you talk to them.
