Antibiotic for acne
Some antibiotics are used to treatacne. In particular these are tetracycline, minocycline and doxycycline.
How do the antibiotics used for acne work?
These medicines combat the infection because of their bacteriostatic action. They enter the bacterial cells. They then inhibit the synthesis of bacterial proteins but do not kill the bacterium. They also have an anti-inflammatory action.
Do they have contraindications or precautions?
These antibiotics may cause skin photosensitivity. People taking them are therefore advised to protect themselves from sunlight whilst they are being treated. Headaches, dizziness and a risk of skin discolouration and bowel problems are amongst the most common side effects.
