I have taken 7 out of 10 of my doses of Levaquin (was prescribed one tab daily for 10 days) for a sinus infection. I want to stop taking the Levaquin and start Augmentin which has been prescribed twice a day for 10 days. This is due to the fact that I am breastfeeding and Augmentin is safer than Levaquin. Do I have to take the full course of the Augmentin or do I just have to take 3 days to make a total of 10 days of antibiotic therapy? Thanks.
