The deworming pill and the symptoms you described have nothing to do with each other, if he is losing his fur and losing weight he is suffering from something serious. Sudden weight loss is always a very big warning light that should not be taken lightly, it's usually a sign of an internal disease that needs to be investigated, i strongly recommend taking him to the vet in order to get it checked, he will need to have a blood test done and possibly an xray as well in order to attempt to diagnose the reason for these symptoms.
