I have read your question,
Since you said acne
which is an anti-biotic tab is not needed unless there is any severe bacterial infection , and generally it is not prescribed . So I suggest you to discontinue it immediately.
I had a previous patient using similar drugs and after using the ointment there may be red patches and scars
on the face.
For you I would recommend using an ayurvedic ointment under brand name "Tadheen balm" for atleast a fortnight for effect.generally this medicine does not have any side effects but if you feel any allergic reactions discontinue it immediately.Further I suggest you to drink a lot of water and B-complex(Vitamin) tabs along with the medication I mentioned above. Steaming can also be done for faster relief.
If the Problem persists I suggest you to consult a Dermatologist
Wishing you a good health,
