Hello Doctor, I Have Been Prescribed GUPISONE 20MG For 10

Hello Doctor,
I have been prescribed GUPISONE 20MG for 10 days due to some acne issues on my face.
As I understand it contains Steriods and I am concerned for weight gain.

Also DOUGLAS 20MG for 30 days x 2 tablets

Kindly let me know if that's an issue as I don't want to gain weight and if possible not have this medicine.

Thanks & Regards
