Post – If you’ve ever had a cold that keeps you up at night coughing or painful urinary tract infections that recur regularly, you may have been tempted to simply help yourself to the antibiotics you’ve been storing since last year in your medicine cabinet. Or you might ask a friend or family member for a few pills. But doctors don’t recommend taking the drugs without a current prescription, because numerous studies over the years have found that using antibiotics improperly can be risky.
