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 impact your ability to take this medication.
Existing kidney disease, as this may affect how your body processes 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 other medications. Never start, stop, or adjust the dosage 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.
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 medication, 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.
When taking this medication, birth control pills and other hormone-based birth control methods may be less effective in preventing pregnancy. To minimize the risk of unplanned pregnancy, use an additional form of birth control, such as a condom, while taking this drug.
If you are pregnant, planning to become pregnant, or breastfeeding, inform your doctor. You and your doctor will need to discuss the potential benefits and risks of this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- Stomach pain
- Nausea
- Vomiting
- Diarrhea
- Rash
- Hyperactivity
- Drowsiness
- Renal dysfunction (crystalluria, renal failure)
- Electrolyte imbalance
What to Do:
Call 1-800-222-1222 (Poison Control Center) immediately or seek emergency medical attention. Treatment is supportive and symptomatic. Hemodialysis can remove amoxicillin and clavulanate from circulation.
Drug Interactions
Major Interactions
- Allopurinol (increased risk of rash)
- Methotrexate (decreased renal clearance of methotrexate, leading to increased toxicity)
- Oral anticoagulants (e.g., Warfarin - increased INR/bleeding risk, mechanism unclear, possibly affecting gut flora or vitamin K synthesis)
- Mycophenolate mofetil (reduced mycophenolic acid concentration, potentially reducing immunosuppressive effect)
Moderate Interactions
- Probenecid (decreased renal tubular secretion of amoxicillin, leading to increased and prolonged amoxicillin levels)
- Oral contraceptives (potential for reduced efficacy due to altered gut flora, though evidence is weak)
- Typhoid vaccine (live, oral) (antibiotics may inactivate the vaccine)
Minor Interactions
- Tetracyclines (may antagonize the bactericidal effect of amoxicillin)
Monitoring
Baseline Monitoring
Rationale: To establish baseline for potential hepatotoxicity, especially in patients with pre-existing hepatic impairment or risk factors.
Timing: Prior to initiation, if clinically indicated.
Rationale: To guide dosage adjustment in patients with renal impairment, as both components are primarily renally excreted.
Timing: Prior to initiation.
Routine Monitoring
Frequency: Daily during therapy
Target: Absence of symptoms
Action Threshold: Any sign of allergic reaction requires immediate discontinuation.
Frequency: Periodically, especially with prolonged use or in patients with risk factors
Target: Absence of symptoms; normal LFTs
Action Threshold: Elevated LFTs or clinical signs require discontinuation and evaluation.
Frequency: Daily during therapy
Target: Normal bowel movements
Action Threshold: Severe or persistent diarrhea may indicate C. difficile infection and requires investigation.
Frequency: More frequently during co-administration and after discontinuation
Target: Therapeutic range for indication
Action Threshold: INR outside target range requires dose adjustment of anticoagulant.
Symptom Monitoring
- Rash
- Itching
- Hives
- Difficulty breathing or swallowing
- Swelling of face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs
- Hoarseness
- Severe diarrhea (watery or bloody)
- Stomach pain or cramps
- Nausea
- Vomiting
- Yellowing of skin or eyes (jaundice)
- Dark urine
- Pale stools
- Unusual tiredness or weakness
- Fever
- Sore throat
- Easy bruising or bleeding
Special Patient Groups
Pregnancy
Generally considered safe for use during 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, but extensive clinical experience suggests no increased risk of birth defects.
Trimester-Specific Risks:
Lactation
Both amoxicillin and clavulanate are excreted in breast milk in small amounts. Generally considered compatible with breastfeeding (Lactation Risk L2 - Safer).
Pediatric Use
Dosing is weight-based (mg/kg/day) and depends on the severity of infection. The 250-125mg tablet formulation may be suitable for older children who can swallow tablets, but suspensions are often preferred for younger children. Ensure appropriate clavulanate limits are not exceeded, especially with higher amoxicillin doses.
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. Dosage adjustment is necessary in elderly patients with renal impairment. Monitor for adverse effects, especially gastrointestinal and hepatic.
Clinical Information
Clinical Pearls
- Always ensure the correct Augmentin formulation is prescribed and dispensed, as the amoxicillin to clavulanate ratio varies (e.g., 250/125, 500/125, 875/125). The 250-125mg tablet has a 2:1 ratio, while 500-125mg and 875-125mg have 4:1 and 7:1 ratios, respectively. This is crucial for avoiding excessive clavulanate exposure, which is associated with increased risk of diarrhea and hepatotoxicity.
- Taking Augmentin with food helps to reduce gastrointestinal side effects like nausea and diarrhea.
- Counsel patients on the importance of completing the full course of therapy to prevent resistance, even if symptoms improve.
- Be vigilant for signs of C. difficile-associated diarrhea (CDAD), which can occur during or after antibiotic therapy.
- Monitor liver function tests in patients with pre-existing hepatic impairment or those on prolonged therapy, as hepatotoxicity, though rare, can be severe.
Alternative Therapies
- Cephalosporins (e.g., Cefuroxime, Cefdinir)
- Macrolides (e.g., Azithromycin, Clarithromycin) - if beta-lactam allergy or atypical pathogens
- Fluoroquinolones (e.g., Levofloxacin, Moxifloxacin) - for specific indications and resistance patterns
- Doxycycline (for certain respiratory or skin infections)
