many of my patients keep a stock supply of antibiotics they don’t finish from a previous infection in an effort to save time and money. you should always finish your medications when you have an infection even if you feel better. what many people do not know is that when you don’t complete your full course of antibiotic therapy you can actually get a more severe infection because the medication did not fully fight all the infection the first time. rather than using tetracycline that may or may not treat the infection you have i would recommend receiving another prescription from your health care provider. it is better use the right drug to fight the right bug.
i lost my cephalexin prescription. can i use my tetracycline in place of the cephalexin?
