I had an allergic reaction (fixed drug eruption) from Etoricoxib and got relief with Atarax, Dazit, and Momate cream, but it left black marks on my back. How can I remove these marks that are now three months old?
The allergic reaction's post-inflammatory hyperpigmentation is what causes the black spots, which typically go away gradually over several months. Fading can be accelerated by using sunscreen every day and a lightening product (such as azelaic acid or moderate retinoids) prescribed by a physician.
