Acne pimples can be treated with metronidazole gel, but this medication is not a first-line medication.
Acne vulgaris is related to the overproliferation of Propionibacterium acnes, which is an anaerobic bacterium, and metronidazole gel is effective in inhibiting the anaerobic bacterium and can improve the condition. However, the use of antibiotic drugs for acne can easily induce drug resistance in Propionibacterium acnes, so it is not recommended to be used alone or not as a first-line drug.
Clinically, the drugs of choice for treating acne vulgaris are retinoids and benzoyl peroxide and azelaic acid. Retinoids can improve follicular sebaceous gland duct keratinization, and benzoyl peroxide and azelaic acid can kill Propionibacterium acnes and dissolve acne. If the inflammation is more pronounced, a combination of antibiotic medications is needed, usually fusidic acid cream and clindamycin ointment.
Metronidazole gel may cause adverse reactions, such as dry skin, burning sensation and skin irritation, pregnant and breastfeeding women should not use it, avoid contact with the eyes and other mucous membranes when using the drug, and it is contraindicated for those who are allergic to metronidazole or any of the ingredients in the drug.
Acne pimples should be treated according to the severity of the choice of appropriate medication under the guidance of a doctor, it is not recommended to blindly use their own medication to avoid adverse reactions.
