Amoxicillin-Clavulanate (Augmentin)

Overview

Amoxicillin-Clavulanate, commonly known by brand name Augmentin, is a combination antibiotic used to treat certain infections caused by susceptible bacteria.

Amoxicillin is a penicillin-class antibiotic. Clavulanate is a beta-lactamase inhibitor that helps prevent certain bacteria from breaking down amoxicillin.

Amoxicillin-Clavulanate may be ordered for certain bacterial lower respiratory tract infections, acute bacterial sinusitis, acute bacterial otitis media, skin and skin structure infections, and urinary tract infections (UTIs). Treatment must be appropriate for patient diagnosis and suspected or identified bacteria.

This article focuses on oral immediate-release tablets. Current tablet labeling covers adults and pediatric patients weighing at least 40 kg. Oral suspension, chewable tablets, and extended-release tablets have different formulation considerations and should not be assumed interchangeable.

For home health nurses, Amoxicillin-Clavulanate indication and home health teaching focuses on verifying why medication was ordered, following prescribed therapy, monitoring infection symptoms, reviewing medication allergies, recognizing significant side effects, and knowing when PCP/provider notification or emergency response is needed.

SN should verify patient-specific indication from current provider order, medication profile, pharmacy label, Hospital discharge instructions, or clarified provider instructions.

Amoxicillin-Clavulanate treats certain bacterial infections. It does not treat viral illnesses such as common cold or flu, and prescribed therapy does not guarantee infection resolution.

Common Indications for Amoxicillin-Clavulanate

Current oral immediate-release tablet labeling identifies the following infection categories when caused by designated susceptible bacteria.

Lower Respiratory Tract Infections

Amoxicillin-Clavulanate may be prescribed for certain bacterial lower respiratory tract infections.

Home health teaching may involve monitoring changes in cough, breathing, sputum when relevant, fatigue, fever, or activity tolerance.

Not every cough or respiratory illness requires this antibiotic.

Acute Bacterial Sinusitis

Amoxicillin-Clavulanate may be ordered for acute bacterial sinusitis caused by susceptible organisms.

Sinus congestion, drainage, or facial discomfort alone does not establish need for antibiotic therapy. Verify provider-documented diagnosis.

Acute Bacterial Otitis Media

Medication may be used for certain bacterial middle-ear infections.

Patient teaching should focus on prescribed therapy, symptom progression, medication tolerance, and ordered follow-up.

Skin and Skin Structure Infections

Amoxicillin-Clavulanate may be ordered for susceptible bacterial skin or skin structure infections.

When patient has provider-diagnosed cellulitis or another applicable skin infection, teaching may include observing redness, warmth, swelling, drainage, and increasing pain.

A wound’s presence alone does not mean antibiotic treatment is indicated.

Urinary Tract Infections

Amoxicillin-Clavulanate may be prescribed for certain UTIs caused by susceptible bacteria.

SN should verify diagnosis and relevant provider instructions. Persistent urinary symptoms alone do not establish that antibiotic should be changed or extended.

Important indication limitation: Current labeling specifies use against designated susceptible organisms. If testing shows bacteria are susceptible to amoxicillin alone, reviewed label advises against using combination product. Antibiotic selection and changes are provider decisions.

Do not infer patient-specific indication from medication name alone.

Short EMR Indication Options

Verify patient-specific reason before use. Examples below are possible Short EMR Indication Options. Select only indication that matches patient diagnosis, provider order, medication profile, Hospital discharge instructions, pharmacy label, or clarified PCP/provider instructions.

Documented diagnosis / reason	Short EMR indication option
Bacterial lower respiratory tract infection	Bacterial lower respiratory infection
Acute bacterial sinusitis	Acute bacterial sinusitis
Acute bacterial otitis media	Bacterial otitis media
Bacterial skin or skin structure infection	Bacterial skin infection
Provider-diagnosed cellulitis, when applicable	Cellulitis treatment
Bacterial urinary tract infection	Bacterial UTI treatment

These are examples of indication labels, not automatic diagnoses.

Do not document “infection prevention,” “antibiotic compliance,” “wound care support,” or another nursing activity as medication indication unless actual provider documentation supports that reason.

What SN Should Verify Before Teaching

Before teaching Amoxicillin-Clavulanate, SN should review current medication information and relevant patient condition.

• Medication and formulation: Confirm Amoxicillin-Clavulanate oral immediate-release tablets and compare current pharmacy label with medication profile.
• Patient-specific indication: Verify which bacterial infection is being treated.
• Prescribed instructions: Verify current provider order, prescribed duration, administration instructions, and any changes after Hospital discharge.
• Allergy history: Review previous reactions to amoxicillin, clavulanate, penicillins, cephalosporins, or other beta-lactam antibiotics.
• Previous liver reaction: Identify any history of jaundice or liver dysfunction associated with Amoxicillin-Clavulanate.
• Relevant medical history: Review kidney impairment, liver disease, mononucleosis, prior antibiotic-associated colitis, or other relevant conditions.
• Current medication list: Identify probenecid, allopurinol, oral anticoagulants, and other medication concerns requiring provider/pharmacist review.
• Current infection findings: Assess relevant symptoms and changes from patient baseline.
• Medication tolerance: Ask about nausea, vomiting, diarrhea, rash, itching, poor intake, or other concerns.
• Patient/PCG ability: Identify difficulty reading labels, organizing medication, recalling instructions, or recognizing reportable symptoms.
• Follow-up plan: Review ordered testing, provider reassessment, and care coordination when applicable.

Important contraindications: Reviewed labeling identifies serious hypersensitivity to Amoxicillin-Clavulanate or other beta-lactam antibacterial drugs, and a previous history of cholestatic jaundice or hepatic dysfunction caused by Amoxicillin-Clavulanate, as contraindications.

SN should communicate relevant history to PCP/provider or pharmacist and not independently determine antibiotic suitability.

Home Health Teaching Focus

Teaching should connect prescribed antibiotic to actual infection being treated and patient/PCG ability to follow instructions safely.

Relevant teaching priorities include:

• knowing why medication was prescribed
• following provider order and pharmacy label
• completing prescribed therapy when appropriate
• recognizing infection improvement or worsening
• understanding common GI effects
• recognizing suspected medication allergy
• knowing which diarrhea or vomiting symptoms require urgent evaluation
• recognizing possible liver-related symptoms
• following provider reassessment instructions
• involving PCG when assistance is needed

Teaching should reflect current clinical findings and actual patient/PCG response. Repeated generic antibiotic education does not, by itself, establish skilled need.

Basic Patient / PCG Teaching

• Take Amoxicillin-Clavulanate according to current provider order and pharmacy label.
• Complete prescribed treatment even if symptoms improve, unless treating provider changes instructions or a suspected serious reaction requires urgent clinical evaluation.
• Do not independently increase, decrease, extend, or otherwise change antibiotic therapy.
• Do not share antibiotics or save leftover medication for another illness.
• Contact PCP/provider or pharmacist for missed-dose concerns rather than independently changing medication schedule.
• Review pharmacy instructions about taking medication with food. Reviewed immediate-release tablet labeling recommends administration at start of a meal to improve tolerance.
• Monitor whether infection symptoms are improving, unchanged, or worsening.
• Report persistent nausea, vomiting, poor intake, or difficulty following prescribed treatment.
• Obtain prompt clinical evaluation for new rash, itching, hives, or other suspected allergic symptoms before further medication use.
• Seek urgent evaluation for severe watery or bloody diarrhea, repeated or prolonged vomiting after medication, or concerning liver symptoms.
• Follow ordered provider appointments, laboratory testing, and medication follow-up.

Medication Safety and Follow-Through

Medication Adherence and Prescribed Completion

Completing antibiotic therapy according to provider instructions helps support appropriate treatment of susceptible bacterial infection.

Reinforce following current pharmacy label and completing prescribed duration unless treating provider changes plan or a serious medication reaction requires urgent evaluation.

Do not independently recommend extra doses, treatment extension, medication substitution, or a different dosing schedule.

Routine antibiotic-completion teaching must not override serious medication-reaction precautions. Current labeling directs discontinuation and appropriate treatment when an allergic reaction or drug-induced enterocolitis syndrome occurs.

Allergy and Severe Skin-Reaction Awareness

Amoxicillin-Clavulanate contains a penicillin-class antibiotic and may cause serious allergic reactions, including anaphylaxis.

Review previous antibiotic allergy history and what reaction actually occurred. A history of serious beta-lactam hypersensitivity requires prescriber/pharmacist review.

New rash, itching, hives, or other suspected allergic symptoms require prompt medical assessment. Do not continue taking medication through a suspected allergic reaction while waiting for routine follow-up.

Severe skin reactions have also been reported. Blistering or peeling skin, painful sores involving mouth or other mucous membranes, or a rapidly worsening rash require urgent medical evaluation.

Call 911 for severe breathing difficulty, significant facial/lip/tongue/throat swelling, collapse, unresponsiveness, or other life-threatening allergic symptoms.

Severe Vomiting and Drug-Induced Enterocolitis Syndrome

Amoxicillin, one component of Amoxicillin-Clavulanate, has been associated with drug-induced enterocolitis syndrome (DIES).

DIES is an uncommon serious reaction involving prolonged or repeated vomiting, often beginning within several hours after medication is taken. It may occur without typical rash or breathing symptoms.

Associated concerns can include paleness, unusual weakness, lethargy, diarrhea, low Blood Pressure, or shock. Most reported cases have occurred in pediatric patients, but warning is relevant when evaluating suspected reactions.

Repeated or prolonged vomiting after medication, particularly with marked weakness, pallor, or lethargy, requires urgent medical evaluation.

Do not dismiss these symptoms as ordinary stomach upset. Current labeling directs discontinuation and appropriate treatment if DIES occurs. SN should not independently diagnose DIES or select replacement therapy.

Call 911 for collapse, unresponsiveness, signs of shock, or other life-threatening symptoms.

Severe Diarrhea and Antibiotic-Associated Colitis

Diarrhea is a common adverse effect of Amoxicillin-Clavulanate.

Some patients may also develop Clostridioides difficile-associated diarrhea, which can range from mild illness to severe colitis.

This complication may occur during antibiotic therapy or more than two months after antibiotic exposure.

Severe, persistent watery or bloody diarrhea, especially with significant abdominal cramping, fever, weakness, or poor intake, requires urgent medical evaluation.

Do not wait for a routine PCP appointment when symptoms are significant.

SN should not independently diagnose C. difficile, recommend OTC diarrhea treatment, or change antibiotic therapy without appropriate clinical instructions.

Liver-Related Precautions

Amoxicillin-Clavulanate can be associated with liver dysfunction, including hepatitis and cholestatic jaundice.

Liver-related symptoms may occur during antibiotic treatment or after treatment has ended.

Report concerning symptoms promptly, including:

• yellowing of skin or eyes
• dark urine
• pale stools
• significant upper abdominal discomfort
• unusual fatigue or weakness
• poor appetite
• unexplained increased bleeding or bruising

These findings require prompt clinical assessment, with urgent evaluation when symptoms suggest significant liver injury or rapid deterioration.

A previous history of cholestatic jaundice or hepatic dysfunction caused by Amoxicillin-Clavulanate must be reviewed before medication is used.

Medication Interactions and Other Precautions

Medication reconciliation remains important during therapy.

Current labeling identifies several concerns:

• Probenecid: Can increase and prolong amoxicillin exposure. Concurrent use is not recommended in reviewed labeling.
• Allopurinol: Concurrent use with amoxicillin is associated with increased risk of skin rash.
• Oral anticoagulants: Increased prothrombin time/INR has been reported. Patients may need provider-directed monitoring.
• Kidney impairment: Severe impairment may require prescriber review of current antibiotic order and formulation.
• Mononucleosis: Amoxicillin-containing medication may cause increased rash concerns in patients with infectious mononucleosis.
• Certain urine glucose tests: Some nonenzymatic urine glucose tests may give false-positive results during amoxicillin therapy. Review testing method with provider or laboratory when relevant.

Pregnancy, breastfeeding, or hormonal contraception questions should be referred to PCP/provider or pharmacist when applicable.

Do not independently change medications, prescribe laboratory tests, or recommend renal-dose adjustments.

Common Side Effects

Possible side effects include:

• diarrhea or loose stools
• nausea
• vomiting
• abdominal discomfort or indigestion
• skin rash or hives
• vaginal itching or symptoms of yeast overgrowth

Not every patient will experience these symptoms.

A new rash may represent medication hypersensitivity and should not automatically be treated as a harmless routine side effect.

---

Reportable Medication Concerns

Report medication concerns according to clinical severity.

Non-emergency concerns requiring PCP/provider or pharmacist review:

• Persistent GI discomfort or poor intake.
• Difficulty following prescribed treatment.
• Medication confusion or missed-dose concern.
• Medication interaction or allergy-history concern.
• Infection symptoms that are not improving as expected.
• Medication supply or pharmacy-label discrepancy.

Concerns requiring prompt or urgent medical evaluation:

• New suspected allergic symptoms.
• Blistering or peeling skin, or painful mucosal sores.
• Severe, persistent watery or bloody diarrhea.
• Repeated or prolonged vomiting after medication, especially with weakness or lethargy.
• Yellowing of skin or eyes, dark urine, or significant upper abdominal discomfort.
• Unusual bleeding or bruising, particularly with relevant medication or liver concerns.

Severe or life-threatening symptoms require 911 rather than routine notification.

---

When to Notify PCP / Provider

Notify PCP/provider or follow agency reporting procedures for:

• Infection symptoms that are not improving or are becoming worse.
• Increasing redness, warmth, swelling, drainage, or pain when treating an applicable skin infection.
• Persistent or worsening respiratory, sinus, ear, or urinary symptoms when relevant to documented diagnosis.
• Persistent nausea, vomiting, poor intake, or difficulty completing prescribed antibiotic therapy.
• Medication discrepancies, missed-dose concerns, or difficulty obtaining medication.
• Unclarified antibiotic allergy or previous liver-related reaction.
• Potential interactions with probenecid, allopurinol, oral anticoagulants, or other relevant medications.
• Patient/PCG uncertainty regarding medication instructions or reportable symptoms.

Urgent clinical evaluation is needed, not routine PCP follow-up alone, for suspected significant allergic reaction, severe skin reaction, severe watery or bloody diarrhea, repeated/prolonged vomiting after medication, or concerning signs of liver injury.

Follow current agency reporting procedures without delaying appropriate urgent or emergency care.

---

When to Call 911

Call 911 for severe or life-threatening symptoms. Follow agency emergency protocol as applicable without delaying emergency response.

Emergency symptoms may include:

• Severe trouble breathing.
• Significant swelling of face, lips, tongue, or throat.
• Severe allergic reaction with respiratory distress.
• Collapse or unresponsiveness.
• Signs of shock, including collapse or inability to respond normally.
• Severe confusion with inability to respond normally.
• Seizure.
• Severe chest pain or severe shortness of breath.
• Rapid clinical deterioration associated with infection or medication reaction.
• Any other severe or life-threatening symptoms.

Do not delay 911 to obtain routine PCP/provider notification.

Home Health Documentation Considerations

For Amoxicillin-Clavulanate, SN documentation should reflect actual patient-specific assessment, teaching, response, and follow-up.

A useful SN note should show:

Verified reason: Why Amoxicillin-Clavulanate is prescribed based on current provider documentation.

Relevant assessment: Infection-related findings, medication tolerance, barriers, or concerns actually assessed.

Teaching provided: Medication purpose, prescribed treatment follow-through, infection monitoring, allergy precautions, severe diarrhea, liver warning signs, or other teaching actually completed.

Patient / PCG response: Actual understanding, teach-back, participation, difficulty, or need for reinforcement.

Provider communication: Abnormal findings or medication concerns communicated to PCP/provider only when contact actually occurred.

Follow-up: Reassessment, continued teaching, or care coordination supported by current findings and plan of care.

Do not assume ongoing skilled need simply because an antibiotic was prescribed.
