Question for Dr. Psisci

In your own professional opinion (and YES i will follow up with my own doc) What would YOU say is the average time that I should have to let pass by after I have stopped taking my Sulfasalazine to see if it is the reason for my RASH, (or not the reason)?

It have been a full week (seven days) so far...... I see my Rheumatologist in 3 weeks.

Thanks...
