How long does it take for Dr. Zaxx to work?
It typically takes about 2 minutes for Dr. Zaxx to start working. Providing you are not experiencing particular discomfort when using Dr. Zaxx, you should use it for up to 5 minutes and no more than 3 times a day. If your headache is gone in less than 5 minutes, simply stop at that point. If you still have a headache after 5 minutes, you should stop using Dr. Zaxx, try relaxing for a while, and try your Dr. Zaxx again after half an hour.
