Xerac AC when applied to the underarms, should be applied to absolutely dry skin. Only apply Xerac AC before bedtime, since medication should be kept on the skin for 6-8 hours. To reduce irritation, let the alcohol evaporate, leaving a thin film of antiperspirant on the skin. Wear a T-shirt, while sleeping to prevent medication from being rubbed off on the bed linens. Do not apply Xerac AC to broken, irritated or recently shaved skin. Wash the treated area next morning with soap and water. Do not apply other deodorants or antiperspirants while using Xerac AC.
