الإجابة: B. Drug effect: rifampicin colours urine red-orange
Rifampicin colours body secretions (urine, tears, sweat) red-orange. This harmless discolouration is mistaken for hematuria (pseudohematuria) in a patient who has just started RIPE therapy. The other options are not recognised adverse effects of these drugs in the sources.
