Hi there, thank you for your question
As long as you finish all 14 pills and do your best to take a pill twice a day for the remaining duration of treatment you should be fine. There will be no need to re-treat. If you are concerned, you can return to the clinic for a “test of cure” 4 weeks after you started the treatment, to make sure the infection is gone.
Let us know if this does not answer your question or if you have any more questionsor concerns.
