Does augmentin affect blood sugar?

If you’re reading this, chances are high that you’d rather be doing anything else. But, since you’re here, I’ll let you in on a secret: antibiotics aren’t exactly known for their fun side effects. Sure, they can help cure infections and save lives, but at what cost? One of the many concerns associated with antibiotic use is blood sugar levels. This article will dive deep into the relationship between augmentin and blood sugar to give some clarity on whether or not your sweet tooth should be worried.

What is Augmentin?

Before we talk about how augmentin affects blood sugar, let’s first establish what it actually is. Developed by GlaxoSmithKline in 1984, augmentin is a combination antibiotic medication containing amoxicillin and clavulanic acid that falls under the class of penicillins used to treat bacterial infections such as sinusitis, pneumonia, bronchitis, UTIs, skin infections, ear infections, among others.

How does Augmentin Work?

Now that we know what augmenting is let’s see how it works – nothing new right!Both amoxicillin and clavulanate work together synergistically to destroy bacteria by inhibiting bacterial cell wall synthesis making them great team players when fighting against diverse types of bacteria also called broad spectrum antibiotics.While Amoxicillin alone fights gram-negative bacteria like E.coli along with other gram-positive organisms(clusters stained purple) including Streptococcus pneumoniae., Clavulanic acid acts as a beta-lactamase inhibitor which alters beta-lactam enzymes produced by certain bacteria thwarting their survival instincts.Sucks if your goal was world domination huh!

Does Augmentin affect Blood Sugar?

So onto the million-dollar question – does all this conflict cause any trouble for people whose main priority isn’t destroying billions of bacterial lives? The answer is yes, augmentin can temporarily increase blood sugar levels. This happens because the medication disrupts the gut microbiome(the ecosystem of microbes that live in your digestive system).The already present harmful bacteria are first to survive and use up all the nutrients required by healthy species(dysbiosis) which translates into decreased insulin sensitivity and increased inflammation – factors contributing towards heightened glucose production.

How significant are Augmentin-induced Changes in Blood Sugar?

Don’t freak out yet though – there’s more to it than just a flat-out “yes.”Research shows that changes usually do not exceed 50ml/dl but remain within normal range AKA no life-threatening issues so far as long you’re monitoring yourself regularly prior taking antibiotic courses.Most often these values would normalize post-treatment.

Risk Factors

A number of factors contribute towards increasing risk for blood sugar variations such as:

  • Higher Body Mass Index(BMI)
  • Long-term diabetes
  • Age – Elderly people have decreased functional reserve capacity hence more susceptible.
  • Chronic kidney disease

It’s important to keep an eye on these if you fall under any of those categories because they could amplify chances of unexpected hyperglycemic episodes(opposite would be hypoglycemia ie low blood sugar levels).

Who should Avoid Augmentin Use due to High Blood Sugar Risk?

People with preexisting glucose-related health conditions like gestational or type 2 diabetes might want to steer clear from antibiotics containing clavulanic acid including Amox K Clav aka augmenting since we’re dealing with beta-lactams here.There’s a significantly higher chance for development time wise as well between usage seasons among individuals who frequently used courses.This may lead unpredictable control difficulties over chronicity when inevitable preventative medical situations arise making choices especially difficult.

Table: Risk Groups Involving Augmentin Usage

Risk Group Notes
Group 1 -Preexisting type 2 diabetes.

-High BMI

Group 2 -Elderly with or without chronic Kidney disease.

It’s better to prevent before regretting later.

This doesn’t mean that augmentin should never be used by people with glucose-related health conditions but rather just needs careful consideration especially from a professional Medical opinion as the intervention modalities will surely vary in such groups thereby leading good risk management strategies.

Clinical Manifestations of High Blood Sugar levels

Symptoms associated with increased blood sugar include lethargy, excessive thirst, headaches along with blurred vision which could potentially lead to hyperosmolar nonketotic coma(HONK) if left untreated. Just in case you were wondering,yes, it’s just as unpleasant as it sounds.

What about Low Blood Sugar?

Let’s slide into discussing low blood sugar – hypoglycemia since some readers might develop anxiety after reading articles related to high numbers.There is limited research validation throughout studies surrounding augmentin-induced hypo-glycemic events.Low sugars can still occur due to food intake changes while being under antibiotic medication affecting normal metabolism.So always Grab an apple or two to munch on every few hours and you’ll probably avoid this problem altogether while still maintaining healthy GI tract during your treatment course.And besides who doesn’t like apples?


While effectiveness wise looking at numerous systemic reviews that compared various beta-lactam antibiotics including amoxicillin-clavulanic acid ,Augmentin scores quite decent when treating respiratory,urinary skin,and soft tissue infections.Additionally,it also tends the make the patient recover back quickly; Curbing drug resistance also seems much effective for C.Difficile colitis which unfortunately represents one major downer – It shouldn’t be prescribed routinely for minor self-limiting ailments like viral URTI’s as a part of unnecessary prophylaxes.


Now, while augmentin-induced blood sugar changes aren’t exactly something to be laughed about(resulting in complex cascading treatments later on), It’s necessary to remember the association isn’t irreversible, and with proper management strategies in place you can emerge unscathed from your antibiotic regimen. So keep those glucose monitors at hand,satisfy your sweet tooth(hopefully not too much!),and all will be well!
