Hi,I'm female, 28 y.o, 5'5 ht., 58 kgs. in wt. and suffering from mild acne for a year now,i have tried different topical solutions such as Dalacin and Zinert for treatment of acne but none of these made an improvement on my face. So i went back to my GP again and was prescribed with Tetralysal antibiotic for 2 months. I had finished the full course treatment and it really improved my skin. My acne was gone. After two weeks of not taking the antibiotic, my acne came back and I'm really worried about it now. What should I do? Should I go back to my GP and ask for another prescription ? I'm just worried that prolong use of antibiotic may cause more problems in the future. Hope you could help me with this matter. Thank you.
