Question: can doxycycline treat a boil?
Answer: If there are concerns about the seriousness of the infection, blood tests may be needed. The doctor may prescribe antibiotics if the infection is severe, such as sulfamethoxazole/trimethoprim (Bactrim), mupirocin (Bactroban), cephalexin (Keflex), clindamycin (Cleocin), doxycycline (Doryx), or vancomycin (Vancocin).
