Augmentin is a prescription antibiotic that combines amoxicillin and
clavulanate potassium. Healthcare professionals may prescribe it for
certain bacterial infections when this combination antibiotic is considered
appropriate.
One commonly used tablet formulation contains 500 mg of amoxicillin
and 125 mg of clavulanate. Because the two components total 625 mg, this
formulation is sometimes referred to as Augmentin 625 mg.
Augmentin is not appropriate for every infection. Antibiotics do not
treat viral illnesses such as the common cold or flu, and choosing an
antibiotic requires consideration of the suspected infection and the patient's
individual circumstances.
A healthcare professional may consider symptoms, medical history,
medication allergies, current medications, previous antibiotic use, and other
relevant factors before determining whether Augmentin or another treatment is
appropriate.
What Is Augmentin?
Augmentin contains two active components:
- Amoxicillin, a
penicillin-class antibacterial medication
- Clavulanate, a
beta-lactamase inhibitor
Amoxicillin works by interfering with bacterial cell-wall synthesis in
susceptible bacteria.
Some bacteria produce beta-lactamase enzymes that can inactivate certain
penicillin-type antibiotics. Clavulanate inhibits certain beta-lactamase
enzymes, helping protect amoxicillin from degradation and extending its
activity against some beta-lactamase-producing bacteria.
This does not mean Augmentin is automatically better or “stronger” than
amoxicillin or another antibiotic. The appropriate antibiotic depends on the
infection being treated and individual clinical circumstances.
What Does Augmentin 500 mg/125 mg
Mean?
The 500 mg/125 mg formulation contains:
- 500 mg of
amoxicillin
- 125 mg of
clavulanate
Together, these active components total 625 mg, which is why the
formulation may sometimes be referred to as Augmentin 625 mg.
Using 500 mg/125 mg is a more precise way to describe the amounts
of the two active components.
Augmentin is available in different formulations and strengths. Patients
should not independently select a formulation, strength, or dosing schedule.
What Is Augmentin Used For?
Augmentin may be prescribed for certain bacterial infections caused by
susceptible organisms.
According to U.S. prescribing information, appropriate uses may include
certain:
- Lower
respiratory tract infections
- Acute bacterial
sinus infections
- Ear infections
- Skin and
skin-structure infections
- Urinary tract
infections
The presence of symptoms associated with one of these conditions does not
automatically mean Augmentin is appropriate.
Respiratory symptoms, sinus discomfort, cough, sore throat, and other
symptoms can have bacterial, viral, or other causes.
A healthcare professional can evaluate the patient's symptoms and health
information before determining whether an antibiotic is needed and, if so,
which antibiotic may be appropriate.
Does Augmentin Treat Viral Infections?
No. Augmentin is an antibacterial medication and does not treat viruses.
It therefore does not treat viral illnesses such as the common cold or
influenza.
Using an antibiotic when it is not needed can expose a patient to
unnecessary medication side effects and contribute to antimicrobial resistance.
This is one reason clinical evaluation is important before beginning
antibiotic treatment.
Why Clinical Evaluation Matters
Selecting an antibiotic involves more than matching symptoms to a
medication.
Before prescribing Augmentin, a healthcare professional may consider:
- The suspected
or confirmed infection
- Symptoms and
their duration
- Severity of
illness
- Relevant
medical history
- Medication
allergies
- Previous
reactions to antibiotics
- Current
medications
- Recent or
previous antibiotic use
- Other
individual clinical considerations
Another antibiotic, additional testing, an in-person examination, or a
non-antibiotic approach may sometimes be more appropriate.
Patients should not take Augmentin simply because they previously
experienced similar symptoms or because another person received it for a
similar condition.
Augmentin Dosage and Proper Use
There is no single Augmentin dosing schedule appropriate for every
patient or infection.
The formulation, dose, frequency, and treatment duration should be
determined by the prescribing healthcare professional according to the
condition being treated and individual patient considerations.
If Augmentin is prescribed, patients should:
- Take the
medication exactly as prescribed
- Follow the
instructions on the prescription label
- Avoid
independently increasing or decreasing the dose
- Avoid taking
medication prescribed for another person
- Contact the
prescribing healthcare professional before changing or stopping treatment
- Ask a
healthcare professional or pharmacist about missed doses or administration
questions
Some formulations have specific instructions related to administration
and food. Patients should follow the directions provided with their particular
prescription.
This article provides general educational information and does not
provide individualized dosing instructions.
Common Side Effects of Augmentin
Like other prescription antibiotics, Augmentin can cause side effects.
Commonly reported effects may include:
- Diarrhea or
loose stools
- Nausea
- Vomiting
- Stomach or
abdominal discomfort
- Skin rash
Other side effects can occur.
Patients should review the medication information accompanying their
prescription and contact a healthcare professional if symptoms are persistent,
unexpected, or concerning.
Serious Reactions and Safety Warnings
Serious reactions can occur with Augmentin.
Patients should seek appropriate medical attention for symptoms that
could indicate a severe allergic reaction, such as:
- Difficulty
breathing
- Significant
swelling
- Widespread
hives
- Severe or
rapidly developing skin reactions
Severe or persistent diarrhea, including watery or bloody diarrhea, can
also require medical evaluation.
Augmentin also has warnings involving liver-related reactions. Patients
experiencing concerning symptoms should contact an appropriate healthcare
professional.
Augmentin and Penicillin Allergies
Augmentin contains amoxicillin, which belongs to the penicillin class of
antibacterial medications.
Before taking Augmentin, patients should tell their healthcare
professional about previous allergic or hypersensitivity reactions to:
- Penicillins
- Cephalosporins
- Other
beta-lactam antibiotics
- Amoxicillin
- Amoxicillin/clavulanate
A history of serious hypersensitivity reactions is particularly important
when determining whether treatment is appropriate.
Patients should not try to determine the significance of a previous
antibiotic reaction themselves. A healthcare professional can evaluate the
patient's allergy history when selecting treatment.
Other Important Safety Considerations
Patients should provide their healthcare professional with complete
information about their medical history and medications before taking
Augmentin.
Relevant considerations can include:
- Medication
allergies
- Previous
antibiotic reactions
- Current
prescription medications
- Over-the-counter
medications
- Vitamins and
supplements
- Kidney
conditions
- Liver
conditions
- Previous
reactions associated with amoxicillin/clavulanate
- Other medical
conditions relevant to treatment
This information helps the prescribing healthcare professional determine
whether Augmentin is appropriate.
Augmentin vs. Amoxicillin: What's the
Difference?
Augmentin and amoxicillin are related, but they are not the same
medication.
Amoxicillin contains the penicillin-class antibacterial medication amoxicillin.
Augmentin combines amoxicillin with clavulanate.
Clavulanate inhibits certain beta-lactamase enzymes that can inactivate
amoxicillin. This can extend activity against some beta-lactamase-producing
bacteria.
However, this does not mean Augmentin should always be chosen instead of
amoxicillin.
The appropriate antibiotic depends on factors such as the infection,
suspected bacteria, susceptibility, allergy history, previous antibiotic use,
and other individual clinical considerations.
Is Augmentin Stronger Than Amoxicillin?
Describing Augmentin simply as “stronger” than amoxicillin can be
misleading.
The addition of clavulanate allows the combination to remain active
against some bacteria that produce beta-lactamase enzymes capable of
inactivating amoxicillin.
That difference may make Augmentin appropriate for certain infections,
but it does not make it the preferred treatment for every bacterial infection.
A healthcare professional should determine which antibiotic is
appropriate for the individual patient.
Augmentin vs. Other Antibiotics
Different antibiotics have different uses, activity, safety
considerations, and potential interactions.
Healthcare professionals may consider:
- The type and
location of the infection
- Suspected or
identified bacteria
- Antibiotic
susceptibility
- Allergy history
- Previous
antibiotic exposure
- Current
medications
- Relevant health
conditions
There is no single antibiotic that is appropriate for every bacterial
infection.
Why Responsible Antibiotic Use Matters
Unnecessary or inappropriate antibiotic use can contribute to
antimicrobial resistance.
Responsible antibiotic use includes:
- Using
antibiotics only when clinically appropriate
- Taking
medication according to the prescription
- Not sharing
prescription antibiotics
- Not taking
medication prescribed for another person
- Not using
leftover antibiotics to self-treat a new illness
- Discussing
questions or concerns with a healthcare professional
Symptoms resembling a previous infection may have a different cause.
Clinical evaluation helps determine whether antibiotic treatment is
appropriate.
Do You Need a Prescription for
Augmentin?
Yes. Augmentin is a prescription medication in the United States.
An appropriately licensed healthcare professional should evaluate the
patient's circumstances and determine whether Augmentin is clinically
appropriate.
Patients should be cautious of sources offering prescription antibiotics
without appropriate medical review.
Prescription approval should not be guaranteed before clinical
evaluation.
Can Augmentin Be Evaluated Through Telehealth?
Depending on the patient's circumstances and applicable requirements, an
appropriately licensed healthcare professional may be able to evaluate certain
conditions through telehealth.
During an online evaluation, a provider may review:
- Current
symptoms
- Duration of
symptoms
- Relevant
medical history
- Medication
allergies
- Current
medications
- Previous
antibiotic use
- Other health
information relevant to prescribing
The healthcare professional then determines whether antibiotic treatment
is appropriate and whether Augmentin, another treatment, additional testing, or
an in-person evaluation should be considered.
Some infections may require physical examination, diagnostic testing, or
other in-person evaluation.
Telehealth access does not mean that a prescription will automatically be
issued.
