The script is for grisovin - 100 tablets with 2 repeats. It seems a little extreme?
I recall there was another choice but the course was longer so I chose the shorter option as we had been dealing with the issue for a couple of months and it was in his hair follicles.

You could always keep the script on hand for jic they are persistent or come back. Remember to keep applying the cream for 2 weeks after they look like they are gone. The mistake I made was stopping too soon and they came back plus more they were already in his hair though so it was never going to go away with just cream.
