In most cases, you should not double the next dose of antibiotics if you’ve missed a dose. Taking a double dose of antibiotics will increase your risk of getting side effects. Take your missed dose as soon as you remember or, if it’s nearly time for your next dose, skip your missed dose altogether.
If you have been fever-free for 24 to 48 hours and are feeling significantly better, “it’s reasonable to call your doctor and ask if you can stop your antibiotic,” she says. And be reassured that “stopping short of a full course of antibiotics won’t worsen the problem of antibiotic resistance,” Peto says.Nov 14, 2018
A growing body of research finds that telling patients to finish a full course of antibiotics even if they’re already feeling better not only fails to prevent drug-resistant “superbugs” from forming, but also might make those pathogens stronger.Jul 28, 2017
Antibiotics, even used for short periods of time, let alone for life-long therapy, raise the issues of both toxicity and the emergence of bacterial antibiotic resistance. (Bacterial antibiotic resistance means that the bacteria do not respond to the antibiotic treatment.)
