My son aged 9 usually have a habit of sneezing in the morning when i wake up. This habit is continuing for last few years. Every morning when he wake up, he continue to sneeze again & again for 15-20 times. After some time, he get normal. Sometimes, when he sleep in the evening, and then wake up, again the same problem of sneezing some times. he has been advised MONTECK LC KID daily once in night. If he takes the tablet he is ok, but if he stops the next day the same symptoms start. What treatment should he take. Is it safe to take the tablets for a long period. If so how many months...
