Bedwetting is a disorder that affects children who are old enough to regulate their urine while sleeping but cannot do so. Nildep Tablet can help your child stop wetting the bed at night. Nildep Tablet works by preventing the bladder muscles from responding to a natural molecule called acetylcholine. This avoids nighttime bladder overflow. However, this medication should only be taken at night to treat bedwetting and should not be given to children under the age of six.
