If your lupus is drug induced.... and many drugs do cause it,
there is another test for that other than ANA. ANA markers can fluctuate quite a bit. People with lupus can test normal one time and elevated ANA another.

If you have angioedema...you will flush ....If you take SSRI antidepressants you will flush, if you have Carcinoid syndrome you will flush like that too. The flush can come from bradykinin (in HAE), or serotonin (drugs, or carcinoid). Not everyone with lupus gets the face butterfly red patch or flush.
I have my lupus flush on my forearms...it goes 1/2 way up. Sometimes it is faint and sometimes brighter.
When I was pregnant and had to take hydralazine for high blood pressure I got a drug induced lupus from that. My knees swelled up terribly for several months. Recently I had another spell of lupus from an Ace inhibitor Lisinopril...that reaction was much more severe.
