Hello Doctor, I Visited A Doctor For My Skin Rash

Hello Doctor,
I visited a Doctor for my skin rash on the fold of my upper left leg which is very itchy. The Doctor advised me to take the following medicines.
1 Eltocin DS 500 mg - twice daily after meal (7 days)
2 Tyza 250 mg - two tablets at a time after dinner. (7 days)
3. Tyza cream - application once at bed time.
4. AS 400 - one tablet each week (Two tablets prescribed)

Is these doses harmful

Thanking you
