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 medication's effectiveness or increase the risk of side effects.
Previous experiences with liver problems or jaundice (turning yellow) while taking this medication.
If you have been diagnosed with mononucleosis (mono), as this may require special consideration.
If you are currently taking 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 in combination with your other treatments and health conditions. 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.
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 is a change in tooth color to yellow-gray-brown, which is more frequently reported in children. In most cases, the discoloration lessens or disappears with regular brushing or dental cleaning. If you experience a change in tooth color, consult with your doctor.
When taking this medication, birth control pills and other hormone-based contraceptives 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, plan to become pregnant, or are 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
- Diarrhea
- Vomiting
- Rash
- Hyperactivity
- Drowsiness
- Renal dysfunction (crystalluria, acute renal failure)
- Seizures (rare, in patients with impaired renal function or high doses)
What to Do:
Seek immediate medical attention or call a poison control center (e.g., 1-800-222-1222). Treatment is largely supportive. Hemodialysis can remove amoxicillin and clavulanate from circulation.
Drug Interactions
Major Interactions
- Warfarin (increased INR, bleeding risk)
- Methotrexate (increased methotrexate levels, toxicity)
Moderate Interactions
- Allopurinol (increased incidence of rash)
- Oral Contraceptives (potential for reduced efficacy, though clinical significance debated)
- Probenecid (decreased renal tubular secretion of amoxicillin, leading to increased and prolonged amoxicillin blood levels)
- Mycophenolate mofetil (reduced mycophenolic acid exposure)
Monitoring
Baseline Monitoring
Rationale: To establish baseline, especially in patients with pre-existing hepatic impairment or risk factors for liver disease.
Timing: Prior to initiation in at-risk patients.
Rationale: To guide appropriate dosing adjustments.
Timing: Prior to initiation.
Routine Monitoring
Frequency: Periodically, especially with prolonged therapy (>14 days) or in patients with pre-existing hepatic impairment.
Target: Within normal limits
Action Threshold: Significant elevation (e.g., >3x ULN) or signs/symptoms of hepatic dysfunction warrant discontinuation and further evaluation.
Frequency: Periodically in patients with pre-existing renal impairment or during prolonged therapy.
Target: Stable or improving
Action Threshold: Deterioration may require dose adjustment.
Frequency: More frequently (e.g., daily to every few days) during co-administration and for several days after discontinuation.
Target: Therapeutic range for indication
Action Threshold: INR outside target range requires warfarin dose adjustment.
Symptom Monitoring
- Diarrhea (especially severe or bloody)
- Nausea/Vomiting
- Rash/Hives
- Itching
- Signs of allergic reaction (swelling of face/throat, difficulty breathing)
- Signs of liver injury (yellowing of skin/eyes, dark urine, unusual fatigue, abdominal pain)
- Signs of superinfection (new or worsening symptoms, oral/vaginal candidiasis)
Special Patient Groups
Pregnancy
Generally considered safe for use during pregnancy (Category B). Studies in animals have not shown harm to the fetus, and human data do not suggest an increased risk of birth defects. However, use only if clearly needed.
Trimester-Specific Risks:
Lactation
Considered compatible with breastfeeding (L2). Both amoxicillin and clavulanate are excreted in small amounts into breast milk. Monitor infant for diarrhea, candidiasis (thrush, diaper rash), or allergic reactions.
Pediatric Use
Dosing is weight-based and varies significantly by age and severity of infection. Careful calculation is essential. Neonates and infants <3 months require specific dosing due to immature renal function. Oral suspension is commonly used for pediatric patients.
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 may be necessary based on renal function, which commonly declines with age. Monitor for hepatic dysfunction.
Clinical Information
Clinical Pearls
- Always administer with food or at the start of a meal to enhance absorption and minimize GI side effects (e.g., diarrhea, nausea).
- The clavulanate component is responsible for most of the GI side effects, particularly diarrhea.
- Ensure patients complete the full prescribed course of therapy, even if symptoms improve, to prevent resistance.
- Amoxicillin/clavulanate is a common cause of drug-induced liver injury, which can be severe and cholestatic, often with a delayed onset (weeks after discontinuation). Monitor LFTs in prolonged therapy or at-risk patients.
- Not effective against MRSA or atypical pathogens.
- The 250mg/5ml suspension typically refers to the amoxicillin component, with clavulanate being a fixed ratio (e.g., 250mg amoxicillin / 62.5mg clavulanate per 5ml). Always verify the exact formulation.
- Different formulations (e.g., 250/125, 500/125, 875/125) have different amoxicillin to clavulanate ratios. The 250mg/5ml suspension is often 250mg amoxicillin with 62.5mg clavulanate per 5ml (4:1 ratio).
- The ES-600 formulation (600mg amoxicillin / 42.9mg clavulanate per 5ml) is specifically designed for pediatric otitis media and has a lower clavulanate ratio to reduce diarrhea.
Alternative Therapies
- Cephalosporins (e.g., Cefdinir, Cefuroxime, Cefpodoxime for respiratory/skin infections)
- Macrolides (e.g., Azithromycin, Clarithromycin for respiratory infections, if beta-lactam allergy)
- Fluoroquinolones (e.g., Levofloxacin, Moxifloxacin for severe respiratory/urinary infections, with caution)
- Doxycycline (for certain respiratory, skin, or atypical infections)
- Clindamycin (for skin and soft tissue infections, anaerobic infections)
