Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
Elevated SGPT may be due to drug induced in you as both dapsone
cause deranged LFT.So if feasible ask your treating Doctor to replace them.
Although it appears to be drug induced in you but still some more common and treatable cause should be looked for like Hepatitis B
and hepatitis C
, ANA and SMA for autoimmune liver disease and lipid profile
I hope I have answered your query and this will help you. Remain in touch
