The choice of antibiotic for a skin infection depends on several factors, including the severity of the infection, the suspected bacteria causing the infection, and the patient's medical history (especially allergies). Treatment should always be guided by a healthcare professional.
First-Line Oral Antibiotics
For many skin infections, oral antibiotics are the first line of defense. Common choices include:
- Flucloxacillin: This is often the initial choice for many bacterial skin infections.
- Penicillins (e.g., amoxicillin, penicillin V, augmentin): These are broad-spectrum antibiotics effective against various bacteria.
Alternatives for Penicillin Allergy or Flucloxacillin Unsuitability
If a patient has a penicillin allergy or flucloxacillin isn't suitable, alternative oral antibiotics may include:
- Clarithromycin: This macrolide antibiotic is a common alternative.
- Erythromycin (oral): This is sometimes used, particularly in pregnancy.
- Doxycycline (oral): Another tetracycline antibiotic that can be an effective option.
Severe Infections & Intravenous Antibiotics
In cases of severe skin infections (e.g., rapidly spreading cellulitis, necrotizing fasciitis), intravenous antibiotics may be necessary. These are administered directly into the bloodstream, offering faster and more effective delivery of the medication. Examples of intravenous antibiotics used for serious infections include:
- Vancomycin: This is often considered first-line for serious MRSA (methicillin-resistant Staphylococcus aureus) infections.
Topical Antibiotics
For minor skin infections, a topical antibiotic ointment may be sufficient. However, these are generally not effective for more serious or widespread infections.
