The antibiotics that I commonly use are Doxycycline(Vibratabs), Cotrimoxazole(Septrim, Bactrim) and Ciprofloxacin(Ciproxin).
Rationale for Use:
The antibiotics treat any infection present in the nose and sinuses.
If you are taking the Pill all antibiotics have the potential to alter its efficacy. You should plan on taking alternative contraceptive measures.
