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 treatments. 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 possible side effect of this medication is a change in tooth color, which may appear as yellow, gray, or brown. This has been reported primarily in children, but in most cases, the discoloration has decreased or resolved 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, plan to become pregnant, or are breastfeeding, inform your doctor. You will need to discuss the potential benefits and risks of this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- Gastrointestinal symptoms (abdominal pain, vomiting, diarrhea)
- Fluid and electrolyte imbalance
- Renal dysfunction (crystalluria, renal failure in severe cases)
- Convulsions (rare)
What to Do:
Call 1-800-222-1222 (Poison Control Center) immediately. 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)
- Allopurinol (increased incidence of rash)
Moderate Interactions
- Oral contraceptives (potential decreased efficacy of oral contraceptives, though clinical significance debated)
- Probenecid (increases amoxicillin levels by decreasing renal tubular secretion)
- Mycophenolate mofetil (decreased mycophenolic acid exposure)
Minor Interactions
- Tetracyclines (may antagonize bactericidal effect of amoxicillin)
Monitoring
Baseline Monitoring
Rationale: To guide appropriate dosing, especially in patients with pre-existing renal impairment.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline, especially in patients with pre-existing hepatic disease or history of amoxicillin/clavulanate-associated jaundice/hepatic dysfunction.
Timing: Prior to initiation of therapy, if indicated.
Routine Monitoring
Frequency: Daily during therapy and for several weeks post-therapy.
Target: Absence of new infections.
Action Threshold: If symptoms appear, evaluate and treat appropriately; consider discontinuing amoxicillin/clavulanate.
Frequency: Periodically, especially with prolonged therapy or in patients with pre-existing hepatic impairment.
Target: Within normal limits or stable.
Action Threshold: Significant elevation (e.g., >3x ULN) or signs of hepatic injury warrant discontinuation and further evaluation.
Frequency: Periodically, especially in patients with pre-existing renal impairment or prolonged therapy.
Target: Stable CrCl.
Action Threshold: Significant decline in CrCl may require dose adjustment or discontinuation.
Frequency: More frequently (e.g., 2-3 times per week) during co-administration and for a few days after discontinuation.
Target: Therapeutic range for indication.
Action Threshold: INR outside target range requires warfarin dose adjustment.
Symptom Monitoring
- Diarrhea (especially severe or persistent, suggestive of C. difficile infection)
- Nausea/vomiting
- Skin rash, itching, hives (signs of allergic reaction)
- Yellowing of skin or eyes (jaundice), dark urine, abdominal pain (signs of hepatic dysfunction)
- Unusual bleeding or bruising (if on warfarin)
- Signs of new infection (e.g., fever, sore throat, vaginal discharge)
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 is no evidence of harm in human pregnancies. However, use only if clearly needed.
Trimester-Specific Risks:
Lactation
Amoxicillin and clavulanate are excreted into breast milk in small amounts. Generally considered compatible with breastfeeding (Lactation Risk L2).
Pediatric Use
The 875/125 mg tablet is generally not suitable for pediatric patients weighing less than 40 kg or those unable to swallow tablets. Pediatric dosing is typically based on the amoxicillin component (mg/kg/day) using oral suspension or chewable tablets. Careful attention to formulation and strength is crucial to avoid clavulanate overdose in younger children.
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 primarily based on renal function, which is often diminished in the elderly. Monitor renal function.
Clinical Information
Clinical Pearls
- Always take with food or milk to minimize gastrointestinal side effects, which are common.
- Ensure patients complete the full course of therapy to prevent resistance and relapse.
- Counsel patients on the importance of reporting severe or persistent diarrhea, as it could indicate C. difficile infection.
- Be vigilant for signs of hepatic dysfunction, especially in patients with pre-existing liver disease or a history of amoxicillin/clavulanate-induced liver injury. This can occur weeks after discontinuation.
- The 875/125 mg tablet has a fixed ratio of amoxicillin to clavulanate. In renal impairment, while amoxicillin dose may need reduction, the clavulanate component can accumulate. For severe renal impairment, alternative formulations (e.g., 250/125 mg or 500/125 mg) or different antibiotics may be more appropriate to allow for proper amoxicillin dosing without excessive clavulanate.
- Patients with a history of penicillin allergy should be carefully assessed; cross-reactivity with amoxicillin is possible.
Alternative Therapies
- Cephalosporins (e.g., cefdinir, cefpodoxime, 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)
