Antibiotics are only used to treat skin rashes caused by bacteria. If the rash is caused by a virus or an allergy, antibiotics will not be effective.
Common oral antibiotics used for skin and soft tissue infections (SSTIs) include:
- Penicillins: amoxicillin, penicillin V, augmentin
- Cephalosporins
- Dicloxacillin
- Clindamycin
- Vancomycin
- Erythromycin
- Tetracycline
It is important to consult with a doctor to determine the best course of treatment for your specific skin rash.
