You fail to specify whether there are any orders in place concerning custody or parent-time. If there are, then you will need to review the current order, in detail, presumably with an experienced family law attorney.
Then, if everything is in order, you will need to take the father to court and either enforce the current orders, or create more specific orders concerning the medications. In doing so, you might be able to be awarded your attorney fees for the work.
You really should communicate with an experienced family law attorney.
