###Human: I have pink rash on the side of my nose that gets worsened in sunlight. What could it be? ###Assistant: Hi. After carefully reading your history I came to a conclusion that there are two possibilities of your rash. Drug reaction: Photoallergic dermatitis: I would advise you take Prednisolone 40 mg in tapering doses and sunscreen with at least 50 spf, thrice daily at 8 AM,11 AM AND 2 PM, with 2.5 finger tip unit (one finger tip unit is the amount of ointment expelled from a tube with a nozzle of 5 mm diameter, from the skin crease that is closest to the end of the finger, to the tip of the index finger) for at least face.
