Adding my two cents worth. He needs to keep himself well hydrated. I have a 24 ounce glass and fill it three times a day and make certain that I drink each one. I also take one 500 mg Cranberry Capsule or Pill every day. I had 6 UTI's in a 4 month period but once I started this regimen I haven't had another. Of course this worked for my system, may not works for his, especially if their is something else in his system that needs attention. He needs to be seen again soon.
