On the heels of the formula crisis, leaving thousands of parents struggling to find enough food to feed their babies, amoxicillin, one of the country’s most commonly used antibiotics to treat bacterial infections such as bronchitis or pneumonia, is the latest shortage to plague parents during peak cold season, officials say. The Food and Drug Administration (FDA) added amoxicillin to its list of drug shortages, specially the “Amoxicillin Oral Powder,” which pharmacists use to mix liquid amoxicillin for infections on October, 28, especially problematic for parents with little ones who are sick and can’t swallow capsules. “The FDA is aware of some intermittent supply interruptions of amoxicillin products in the U.S, and is currently working with the approved manufacturers,” a spokesperson for the FDA told The Post in an email. In addition shortages of liquid amoxicillin, The American Society of Health-System Pharmacists, on Oct. 31, also added various dosages of the capsules and tablets, according to its website.
