What is the difference between clavamox and amoxicillin?

When it comes to antibiotics, there are many different types out there. Some are more powerful than others, while some may be better suited for certain conditions. Two commonly prescribed antibiotics are clavamox and amoxicillin but what exactly is the difference between these two drugs? In this article, we’ll get down to the nitty-gritty details of clavamox vs amoxicillin.

The Basics: What Are Clavamox and Amoxicillin?

Before we dive into their differences, let’s first discuss what each drug actually is:


Clavamox is a combination antibiotic that contains both amoxicillin trihydrate and clavulanate potassium. Essentially, this means that it has a broader spectrum of activity against bacteria than just regular old amoxicillin.

Clavulanate potassium helps prevent bacterial resistance by inhibiting enzymes produced by bacteria that could potentially destroy or neutralize the effectiveness of standard antibiotics like amoxicillin.


Amoxicillin itself belongs to a group of medicines called ‘penicillins’ (not to be confused with pencil-necks). This type of antibiotic works by killing bacteria cells in order tåo stop them from growing further.

Fun fact: penicillins were discovered last century when Alexander Fleming noticed something odd growing on one of his Petri dishes – talk about serendipity!

Now that we’ve got the basics covered, let’s move onto understanding how these two differ in terms of usage.

Differences in Usage

While they have similar properties,there are important distinctions between clavamox and amoxicllin:

When Should You Take Clavanomx Over Other Antibiotics?

  • Respiratory infections
    Acute respiratory tract infections such as pneumonia require alternatives such as clavamox due to their broader spectrum of activity.

  • Ear, skin & urinary tract infections
    Veterinarians may prescribe Clavamox for a bacterial infection related to these specific areas.

  • Antibiotic resistant bacteria

Some strains have become immune to the effects of certain antibiotics, and in such cases, clavamox could be prescribed because it has additional chemicals (like the aforementioned clauvlanate potassium) that can inhibit bacteria growth where standard drugs cannot.

It’s true that both agents work against a variety of gram-positive (+) and gram-negative (-) bacterias – this means they improve nutrition-absorption processes while also fighting off harmful pathogens. However,they differ in terms of dosage guidelines:

How are Dosages Determined?

When I talk about ‘dosage’, I am actually referring to how much medication needs to be given based on weight or dose strength. This applies for every type of drug out there from cold medicine all the way up to antipsychotic medications used for mental illnesses!

Dosages suggested by veterinarians will depend on various factors such as your dog’s weight or health condition(s). For example:

Amoxicillin dosing

When considering dosing with amoxicillin,vets take note of age differences:

Age Dose
Pups 50 mg/kg orally once daily
Adult dogs 5–20 mg/kg PO q8h

For both adult dogs and puppies, duration time usually lasts between seven days up until fourteen days but would still depend largely on what exactly is being treated.

Clavanomx dosing

All things considered,there shouldn’t be too many significant variances when it comes down measuring doses rather than physicality assessments made beforehand:

Weight Range Oral Tablet Strengths
22 – 44 lb 62.5mg Amoxicillin/Clavulanate
44 – 88 lb 125 mg Amoxicillin / Clavulanate
88+ lbs To be determined by the Vet

Both amoxicillin and clavanomx must never be given to dogs unless they advise or write a prescription for you specifically-it’s better safe than sorry as under dosage can result in ineffective treatments or worse, antimicrobial resistance.

Possible Side Effects To Look Out For

Like any other medication, these two antibiotics may have potential side effects that come hand-in-hand with their ingestion:

Common Short-Term Adverse Reactions

Common short-term adverse reactions for both drugs include:

  • Diarrhea
  • Vomiting

As we noted earlier,clavamox comes with extra antibiotics within it (in order to prevent bacterial resistance) which also makes it more complex in terms of possible side effects experienced:

Scalp Skin Lesion

This scalp skin reaction could manifest typically between two weeks after hair loss , discharge secretions – this is very rare

Excessive Panting

When taken at overly high doses over a long period of time (which shouldn’t happen if dosages are strictly adhered to), excessive panting may become present when taking clavanomx orally.

Signs like vomiting and diarrhea could potentially log more frequently while but will not always occur.

If there are any unusual symptoms constantly occurring, make an appointment with your vet immediately.

Differences In Costs Between These Medications?

It goes without sayingthat what plays a major role ultimately in going towards either drug would possibly depend heavily on cost differences
Your veterinary care size would determine pricing ultimately though others factors determine prices generally such as;

• Size & Weight – dosages required vary based on this metric so some caregivers might need to use more medication than others
• Health of dog – dogs with pre-existing conditions might require different dosages as well

All in all, while some antibiotics are certainly pricier compared to others,there aren’t generally any feasible differences in costs when comparing Clavamox vs. Amoxicillin since they’re offered per pill.

At the end of the day, prevention is worth a cure; you won’t need much drugs If your furry bundle of joy exercises frequently and consistently by taking him for walks around your neighborhood streets or even in wooded natural areas generously sprinkled with fauna and flora!

Conclusion: Which Drug Wins?

If we had to judge simply based on their effectiveness relative to one another, neither wins outright – efficacy rates are high for both amoxicillin and clavamox respectively. Most times doctors will decide what works best depending on type(s) presentations presented ie. coughing fits/hotspots that would lead them towards recommending either drug against another.Primarily though it still ultimately depends on who amongst these two can ruin your wallet less because there just isn’t too much differentiation between factors such as side-effects or contraction timeframes

And with that said,I’d like to give my K9 sergeant (you guessed it right – I’m definitely not human!) standing beside me off camera (well … virtually… he’s lying next to me snoring happily away),a treat made up of this kind: low-fat cream cheese,Salted peanut butter mixed together poured into silicon tray-shaped mini-molds,frozen then taken smack dab outta the freezer for consumption!!

Stay safe folks!
