Before Using This Medicine
It is essential to inform your doctor about the following conditions to ensure safe treatment:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction and its symptoms.
If you are allergic to penicillin, as this may affect your ability to take this medication.
Existing kidney disease, as this may impact the dosage or administration of the medication.
Previous experiences with liver problems or jaundice (turning yellow) while taking this medication.
If you have been diagnosed with mononucleosis (mono).
Current use of probenecid, as this may interact with the medication.
This list is not exhaustive, and it is crucial to discuss all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, with your doctor and pharmacist. They will help you determine if it is safe to take this medication with your existing health conditions and medications. Never start, stop, or change the dose of any medication without consulting your doctor first.
Precautions & Cautions
This medication may interfere with certain laboratory tests, so it is crucial to notify all your healthcare providers and lab personnel that you are taking this drug. If you have diabetes and test your urine glucose levels, consult with your doctor to determine the most suitable tests to use.
Individuals with phenylketonuria (PKU) should discuss this condition with their doctor, as some products may contain phenylalanine.
Do not take this medication for longer than prescribed, as this may increase the risk of a second infection. A common side effect of this drug, particularly in children, is a change in tooth color to a yellow-gray-brown hue. In most cases, this discoloration can be reduced or eliminated with regular brushing or dental cleaning. If you notice any changes in tooth color, consult with your doctor.
Women taking birth control pills or other hormone-based contraceptives should be aware that this medication may reduce their effectiveness. To prevent pregnancy, consider using an additional form of birth control, such as a condom, while taking this drug.
If you are pregnant, plan to become pregnant, or are breastfeeding, inform your doctor. You will need to discuss the potential benefits and risks of taking this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- Gastrointestinal symptoms (nausea, vomiting, diarrhea)
- Electrolyte imbalance
- Crystalluria (in severe cases, leading to renal failure)
- Convulsions (rare, in patients with impaired renal function or high doses)
What to Do:
Call 1-800-222-1222 (Poison Control). Treatment is symptomatic and supportive. Hemodialysis can remove amoxicillin and clavulanate from circulation.
Drug Interactions
Major Interactions
- Allopurinol (increased risk of rash)
- Warfarin and other oral anticoagulants (increased INR/bleeding risk)
- Methotrexate (decreased renal clearance of methotrexate, leading to increased toxicity)
- Mycophenolate mofetil (reduced mycophenolic acid concentration)
Moderate Interactions
- Probenecid (decreased renal tubular secretion of amoxicillin, leading to increased and prolonged amoxicillin levels)
- Oral contraceptives (potential for reduced efficacy, though evidence is limited and controversial)
- Typhoid vaccine (live, oral) (antibiotics may inactivate the vaccine)
- Tetracyclines (may interfere with bactericidal effect of penicillins)
Minor Interactions
- Aminoglycosides (in vitro inactivation, but not clinically significant in vivo for systemic use)
Monitoring
Baseline Monitoring
Rationale: To prevent hypersensitivity reactions.
Timing: Prior to initiation of therapy.
Rationale: To guide dose adjustment in renal impairment.
Timing: Prior to initiation, especially in elderly or those with suspected renal issues.
Rationale: To assess baseline hepatic status, especially in patients with pre-existing liver disease or history of drug-induced liver injury.
Timing: Prior to initiation, if clinically indicated.
Routine Monitoring
Frequency: Daily
Target: Improvement in fever, pain, inflammation
Action Threshold: Lack of improvement or worsening symptoms after 2-3 days may indicate treatment failure or resistant organism.
Frequency: Daily
Target: Minimal to no GI upset
Action Threshold: Severe or persistent diarrhea (especially bloody) may indicate C. difficile infection; severe nausea/vomiting may require discontinuation.
Frequency: Periodically, especially with prolonged therapy or in patients with hepatic impairment
Target: Within normal limits or stable
Action Threshold: Significant elevation (e.g., >3x ULN) may indicate drug-induced liver injury and require discontinuation.
Frequency: Periodically, especially with prolonged therapy or in patients with renal impairment
Target: Stable
Action Threshold: Significant decline may require further dose adjustment.
Symptom Monitoring
- Rash (maculopapular, urticarial)
- Pruritus
- Dyspnea, wheezing, angioedema (signs of anaphylaxis)
- Severe or persistent diarrhea (especially bloody or watery)
- Yellowing of skin or eyes (jaundice)
- Dark urine, pale stools
- Unusual fatigue or weakness
- Abdominal pain
Special Patient Groups
Pregnancy
Category B. Studies in animals have not shown harm to the fetus, and there are no adequate and well-controlled studies in pregnant women. Generally considered safe for use during pregnancy when clearly needed.
Trimester-Specific Risks:
Lactation
L1 (Compatible). Both amoxicillin and clavulanate are excreted in breast milk in small amounts. Generally considered safe for nursing infants. Monitor infant for diarrhea, candidiasis (thrush, diaper rash), or allergic reactions.
Pediatric Use
Dosing is weight-based and depends on the severity and type of infection. The 400mg/5ml formulation (7:1 ratio) is commonly used for pediatric patients. Ensure accurate measurement using an oral syringe or measuring spoon. Not recommended for neonates without specific guidelines.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Dose adjustment is necessary based on renal function, which is often decreased in the elderly. Monitor for adverse effects, especially GI upset and liver function.
Clinical Information
Clinical Pearls
- Always confirm the specific Augmentin formulation (e.g., 400mg/5ml, 600mg/5ml, 875mg/125mg) as the amoxicillin to clavulanate ratio can vary, impacting dosing, especially in pediatrics.
- Taking Augmentin with food, particularly at the start of a meal, significantly reduces the incidence of gastrointestinal side effects (e.g., diarrhea, nausea).
- Diarrhea is a common side effect; advise patients to report severe or persistent diarrhea, as it could indicate Clostridioides difficile-associated diarrhea (CDAD).
- Liver dysfunction, including cholestatic jaundice, can occur, even after discontinuation of therapy. Monitor LFTs in patients with pre-existing hepatic impairment or during prolonged therapy.
- Ensure patients understand the importance of completing the full course of antibiotics to prevent antibiotic resistance and relapse.
- The suspension must be refrigerated after reconstitution and discarded after 10 days.
Alternative Therapies
- Cephalosporins (e.g., Cefdinir, Cefuroxime, Ceftriaxone)
- Macrolides (e.g., Azithromycin, Clarithromycin) - for atypical pathogens or penicillin allergy
- Fluoroquinolones (e.g., Levofloxacin, Moxifloxacin) - for specific indications and resistance patterns
- Doxycycline (for certain respiratory or skin infections)
