What medication can be used to treat body odor?

Generally, under a doctor's guidance, patients can use medications such as compound glutaraldehyde solution, urotropine solution, chlorhexidine acetate solution, botulinum toxin type A for injection, and potassium permanganate solution to treat body odor (bromhidrosis). Detailed explanations are as follows:

1. Compound Glutaraldehyde Solution

Compound glutaraldehyde solution has disinfectant and antibacterial properties. It can inhibit bacterial growth under the armpits, reduce the decomposition of apocrine gland secretions by bacteria, and thus alleviate odor. This solution should be diluted as directed by a physician and must avoid direct contact with damaged skin. It is suitable for daily odor relief in patients with mild to moderate bromhidrosis.

2. Urotropine Solution

Urotropine solution suppresses apocrine gland secretion by constricting sweat gland ducts, thereby reducing sweat output. It also has certain antibacterial effects, helping to reduce odor at its source. This medication is suitable for bromhidrosis caused by excessive sweat gland secretion. Care should be taken not to use excessive amounts, to avoid skin dryness or irritation.

3. Chlorhexidine Acetate Solution

Chlorhexidine acetate solution is a commonly used disinfectant that effectively kills both Gram-positive and Gram-negative bacteria. It helps eliminate harmful bacteria under the armpits and prevents the bacterial breakdown of sweat that causes odor. It is suitable for patients with bromhidrosis accompanied by localized bacterial infection. It can be applied after cleaning the underarm area to reduce odor intensity.

4. Botulinum Toxin Type A for Injection

Botulinum toxin type A injections work by inhibiting the release of acetylcholine at nerve endings, reducing the neural stimulation of apocrine glands, thereby decreasing sweat gland secretion and reducing sweating and associated odor. This treatment must be administered by a qualified physician. The effect typically lasts for several months and is suitable for patients with moderate to severe bromhidrosis.

5. Potassium Permanganate Solution

Potassium permanganate solution has strong oxidizing properties and can kill bacteria under the armpits, disrupt odor-causing substances produced by bacterial breakdown of sweat, and also has a mild astringent effect, reducing sweat secretion. The concentration must strictly follow medical instructions to avoid skin burns due to excessive concentration. It is suitable for short-term odor improvement in patients with mild bromhidrosis.

Maintaining good daily habits is also important. Bathe and change clothes regularly, wear loose and breathable cotton clothing to keep the underarm area dry and clean. Avoid consuming spicy and pungent foods such as garlic, onions, and chili peppers, which may exacerbate odor secretion.
