A recent school of thought among many practicing Dermatologists across the world is to avoid antibiotics as much as possible except only when needed to curb the emerging antibiotic resistance.

Types Of Antibiotics For Acne
Antibiotics used in acne treatment are of two kinds– oral and topical. Oral antibiotics (systemic) work internally by treating inflammation occurring around glands while topical antibiotics (surface) permeate the epidermis, reduce inflammation and help in preventing the occlusion of the pores.
Your dermatologist may advise the use of either form of medications depending on the severity of the concern. He/She may even prescribe a combination of both to treat acute cases of acne.
- Oral Antibiotics For Acne
These are great for treating moderate to severe acne, with the tetracycline group being the first choice of medication. A dermatologist is the best person to advise the dose of antibiotics and the duration for which you may need them.
Oral antibiotics are more effective in treating acne when used along with topical retinoids and benzoyl peroxide. This combination can reduce the risk of developing antibiotic resistance.
Common antibiotics used in acne treatment are Tetracycline group which may include Doxycycline, Minocycline, Trimethoprim and Cotrimoxazole for example.
- Topical Antibiotics Used In Acne Treatment
Topical antibiotics are available in the form of cream, gel, or lotion that you need to apply to the affected area as advised by the doctor for the stipulated period of time. They help in inhibiting the growth of bacteria and reducing inflammation. Though these topical antibiotics are effective, dermatologists generally recommend them along with other methods of acne treatments.
Topical medications containing benzoyl peroxide or salicylic acid (please note salicylic acid and benzoyl peroxide are antibiotics) though they are not proper antibiotics have proven efficacy in clearing mild to moderate acne by various other mechanisms though benzoyl peroxide has good antibacterial activity. Clindamycin or dapsone are the two main active ingredients present in the antibiotic creams that are popular in India.
- Benzoyl peroxide – It is a drug from peroxide family which has a keratolytic (exfoliative), comedolytic (anti-clogging), anti-inflammatory and antibacterial activity. It is an antibacterial agent that doctors use in combination with other antibiotics for specific treatment of acne. For example, clindamycin works with benzoyl peroxide and erythromycin with benzoyl peroxide.
- Salicylic acid – It helps to exfoliate the skin and prevent hair follicles from clogging. It is also used as a chemical peel as it has an anti-inflammatory effect while removing the top layer of skin.
- Dapsone, 5% gel – It helps treat cases of inflammatory acne. Dermatologists may recommend the antibiotic cream in a case-specific manner.

Controversies Around The Use Of Antibiotics For Acne
