Gelong ammonium bromide cream is used for local antiperspirant under the armpit. Common local adverse reactions include dry skin, itching, and erythema, which are mostly mild to moderate and can gradually alleviate with prolonged use. Scientific management can improve tolerance and compliance.

1、 Dry skin

Drying is one of the most common reactions. It is recommended to ensure that the skin under the armpit is completely dry before medication, and apply a thin layer to avoid excessive or repeated application. The humectant without essence and low irritation can be used daily, but it should be staggered with the time of application: those who use it before sleep can moisturize after cleaning in the morning of the next day to avoid that the humectant and drug can be applied at the same time to affect absorption or increase irritation. The temperature of the bath water should not be too high, and the use of alkaline soap should be reduced.

2、 Itching sensation

Mild itching can be observed first, avoiding scratching to prevent skin damage and secondary infection. Can be relieved by cold compress, wear loose and breathable clothing to reduce friction. If the itching persists or worsens, the medication can be suspended for 1-2 days and resumed after the symptoms subside; When it repeatedly occurs, consult a doctor to evaluate whether to adjust the frequency of medication or change the plan. Avoid using other irritating topical products simultaneously.

3、 Red Spot

Mild erythema usually does not require discontinuation of medication. Pay attention to keeping the area clean and dry, avoiding hot water washing and rubbing against tight clothing. If the redness area expands, accompanied by a burning sensation or swelling, medication should be suspended and medical attention sought. Confirm that the skin is not damaged before medication, and the damaged area should not be applied.

4、 Overall recommendations

For the first use, you can try it out on a small area and observe the reaction for 24 hours. Record the time and severity of symptoms to facilitate doctors' judgment. Seek medical attention promptly when severe or persistent skin reactions or signs of secondary infection occur. Pregnant women, lactating women, and children should consult a physician before taking medication. Standardized dosage, thin application, and staggered moisturizing time are key to reducing local side effects.
