what happens when a patient doesn't take the full course of antibiotics

by Thomas Feil 8 min read

If you stop taking your antibiotics early, the bacteria causing your infection may not have been completely cleared, and your infection could return. It’s also possible that these remaining bacteria could develop resistance to the antibiotic. Antibiotic resistance is a major public health concern.

“When you halt treatment early, you allow a small portion of bacteria to remain in your body and that bacteria has the potential to strengthen, change, and develop resistance.” So even if you're feeling better after a few days, that doesn't mean all of the bacteria which made you sick is actually gone yet.Aug 27, 2019

What happens if you cut antibiotics short?

The kind of antibiotics prescribed by your doctor, and the length of the course, are based on the best evidence for what will kill all of the bacteria.

How long should antibiotics be given?

Here’s the bottom line 1 Antibiotics are a limited resource, and they should be used wisely and selectively. 2 Antibiotics may also have serious side effects, such as the major intestinal ailment Clostridium difficile colitis. 3 There is no evidence that longer courses prevent the development of antibiotic resistance. In fact, just the opposite may be true. 4 Instructions about length of antibiotic therapy are sometimes arbitrary, and some patients may recover faster and need fewer days of antibiotics than others. 5 You should still follow your doctor’s instructions about the length of antibiotic therapy. 6 If you are feeling better and think that you may not need the entire course, be sure to ask your doctor first. 7 Antibiotic administration is not necessary for all infections. In particular, most upper respiratory infections are viral, and do not respond to antibiotics.

What is the blood test for antibiotics?

Doctors are studying new clinical tools to help limit unnecessary antibiotic use. One of these is a blood test called procalcitonin. Levels of procalcitonin rise in patients with serious bacterial infections. In patients with viral infections, which do not respond to antibiotics, procalcitonin levels are suppressed.

Why is procalcitonin suppressed?

In patients with viral infections, which do not respond to antibiotics, procalcitonin levels are suppressed. Currently, procalcitonin levels are used in the hospital setting to help decide whether patients with flares of COPD (chronic obstructive pulmonary disease) or pneumonia are likely to need antibiotics or not.

How long does it take for a bloodstream infection to cure?

Today, we know that patients with bloodstream infections may require several weeks of antibiotics for cure, and those with active tuberculosis need many months of multiple antibiotics. But these patients are not representative of most people who receive antibiotics today.

Can antibiotics cause colitis?

Antibiotics are a limited resource, and they should be used wisely and selectively. Antibiotics may also have serious side effects, such as the major intestinal ailment Clostridium difficile colitis . There is no evidence that longer courses prevent the development of antibiotic resistance. In fact, just the opposite may be true.

Do you need antibiotics for upper respiratory infections?

If you are feeling better and think that you may not need the entire course, be sure to ask your doctor first. Antibiotic administration is not necessary for all infections. In particular, most upper respiratory infections are viral, and do not respond to antibiotics.

Is antibiotic resistance a threat?

Antibiotic resistance is an emerging threat to public health. If the arsenal of effective antibiotics dwindles, treating infection becomes more difficult. Conventional wisdom has long held that stopping a course of antibiotics early may be a major cause of antibiotic resistance. But is this really supported by the evidence?

How many antibiotics are unnecessary?

According to the Centers for Disease Control and Prevention (CDC) Trusted Source. , roughly 1 in 3 antibiotic prescriptions outside of a hospital setting are unnecessary. Total “inappropriate” antibiotic use, which includes incorrect dosing and duration, is nearly 50 percent.

What is the message of taking until you feel better?

Doctors would have to convey a message to patients that is both safe and effective. A message such as “take until you feel better,” is somewhat ambiguous and could create problems in an outpatient setting. “What people are tolerant of in terms of symptoms can matter,” said Olden.

Do you have to take all your antibiotics?

No Need to Take All Your Antibiotics, Researchers Say. Scientists say the ‘complete the course’ recommendation isn’t backed by science and may be encouraging antibiotic resistance. Some doctors agree.

Is the complete the course message unnecessary?

Researchers argue that not only is the “complete the course” message unnecessary, it is actively contributing to the growth of antibiotic-resistant bacteria — not preventing it.

Is it necessary to finish all antibiotics?

An article in the BMJ argues that contrary to long-given advice, it is unnecessary to make sure you finish all the antibiotics you’re prescribed. The article sparked debate among experts and more worryingly widespread confusion among the general public, who are still getting to grips with what they need to do to stem antibiotic resistance.

Can antibiotics be useless against a recurrent infection?

If the latter is true, the persistent population in your body that is causing your recurrent infection could well be resistant to that first set of antibiotics, meaning those antibiotics may well be useless against your infection. Antibiotic resistance is about survival of the fittest.
