Yes, Xylocaine NF is used in combination with prilocaine for premature ejaculation. It improves sexual satisfaction and ejaculatory control by decreasing the sensation of the genital skin. It has no systemic effects and has minimum local side effects. Premature ejaculation can be psychological or biological. It could be because of over-sensitive genital skin, extreme arousal, infrequent sexual activity, hyperactive reflexes, fear, performance anxiety, use of alcohol and other substances, inflammation of the urethra, prostate, etc. In addition, it is also important to take treatment and comply with it completely.

According to an FDA warning published in 2014, a 2% solution of Xylocaine NF should not be used in infants and young children (5 months to 3.5 years old), as too much application of Xylocaine NF or accidental swallowing may cause serious brain injury, seizures, and heart problems. Therefore, for treating teething pain, one must take the advice of their doctor and follow his recommendations completely.
