Hello,
Thanks for the query.
P. Roseae is a disease with varied cause. It can be associated with drug as mentioned by you, but that is rare.
The most common association is with herpes virus 7.
It will be better to try a course of anti viral like acyclovir.
You can XXXXXXX a dermatologist and request for a prescription.
I would like to see the lesions, this will help me in ascertaining that you dont have any other disease. Please upload a photograph of the lesion. There is an option to upload photographs on right side of query page.
Waiting for your response.
Thank you

Currently at work so it is not possible to send a photo. The diagnosis was made via a skin biopsy if that helps

Hello XXXXXXX
Thanks for the follow up.
If biopsy was done then the diagnosis must be correct.
Please XXXXXXX the doctor once again and discuss regarding anti viral treatment.
Thank you
