Chlamydia question? Answers ASAP plz

Ra
My husband and I recently found out we had chlamydia.. Fast forward this afternoon we went to get treated. We didn't eat anything so we were given the prescription (4tabs) around 1pm I took mine after eating. I fault nauseated hours later. By 4pm I ended up getting sick and puking.. Am I safe for the 3 hr difference? Or do I have to take another dose?
