answer:Well, it’s a crap shoot probably. How often an antibiotic is prescribed has to do with it’s half life, usually taking the next dose as the levels of medication in your blood stream reaches half as the body breaks it down, we take the next dose. Low levels by skipping a pill means the actions of reducing the bacteria being treated is hampered. The antibiotics are systematically killing of bacteria and stopping it from multiplying. A basic example is let’s say you have 1 million bacteria causing your illness. The first pill might reduce it to 800,000; the second pill 600,000; the third pill 400,000, going down until you are well. The reason they say take the medication until the end even if you feel better is because one might be asymptomatic when the numbers of bacteria are low, but if not obliterated, once you stop taking the medication they just start multiplying up again. Skipping a pill means the bacteria possibly had opportunity to build back up in numbers again. If the drug you take is once a day, it has a long half life and possibly you are ok if you took it as soon as possible, I would not wait 24 hours to take the next pill at the regular time, it is probably almost akin to starting new as if you never took a pill in the first place. Most likely any instruction that came with your medication states to take a missed dose as soon as you realize, but don’t take two pills together. You would have to check your paperwork to know. You can call your doctor or pharamicist for advise as well. Obviously, no information on the internet should be taken as medical advice. I’m not a doctor and the numbers I stated in the example are just for examply, totally made up.
