What Antibiotics Are Used for Skin Rashes and Itching?

Published in Skin Antibiotics 2 mins read

Oral antibiotics are used to treat skin conditions, including some that present with rashes and itching. While antibiotics primarily target bacterial infections and are not the first line of treatment for general skin rashes or itchiness, certain skin infections with these symptoms may require them. According to the reference, some common antibiotics used include dicloxacillin, erythromycin, and tetracycline.

Understanding Antibiotics for Skin Issues

It's important to understand that antibiotics are not a universal remedy for all skin rashes or itching. They are specifically effective against bacterial infections. If a skin condition is caused by viruses, fungi, allergies, or other factors, antibiotics will not help and may even lead to unnecessary side effects.

Examples of Bacterial Skin Infections Treated with Antibiotics

Certain bacterial skin infections which might present with rashes and itching, and for which antibiotics may be prescribed, include:

  • Cellulitis: A common bacterial infection of the skin and underlying tissues. It often appears as a red, swollen, and painful area of skin.
  • Impetigo: A highly contagious bacterial infection that causes red sores, often around the nose and mouth.
  • Folliculitis: An infection of the hair follicles, which can cause small red bumps or pimples.

Types of Antibiotics Used

The choice of antibiotic will depend on the specific bacteria causing the infection. As previously noted, some common oral antibiotics used for skin infections are:


Antibiotic Use
Dicloxacillin Often used to treat infections caused by staphylococcus bacteria.
Erythromycin A macrolide antibiotic used to treat a variety of bacterial infections, sometimes used if other antibiotics cannot be.
Tetracycline A broad-spectrum antibiotic, used for some skin infections, among other conditions.


Important Considerations:

  • Consultation: Always consult a healthcare professional before starting any antibiotic. They will diagnose the condition and prescribe the most appropriate treatment.
  • Antibiotic Resistance: Overuse or improper use of antibiotics can lead to antibiotic resistance, making future infections harder to treat. Always follow your doctor's instructions exactly and complete the full course of prescribed antibiotics, even if symptoms improve.
  • Side Effects: All antibiotics can cause side effects. Discuss any concerns or allergies with your doctor or pharmacist.


In summary, while certain antibiotics like dicloxacillin, erythromycin, and tetracycline are used to treat bacterial skin infections that may cause rashes and itching, they are not a cure-all. It’s important to consult a medical professional for accurate diagnosis and treatment.
