Common use

Cenmox is indicated for the treatment of bacterial infections caused by susceptible strains of microorganisms. Common clinical applications include respiratory tract infections such as bronchitis, pneumonia, and sinusitis; ear, nose, and throat infections including otitis media and pharyngitis; genitourinary infections such as cystitis and urethritis; skin and soft tissue infections; and dental abscesses. It is also used as part of combination therapy for Helicobacter pylori eradication.

Dosage and direction

The dosage of Cenmox must be individualized based on the infection severity, pathogen susceptibility, and patient factors including renal function.

Adults and children ≥40 kg:

• Mild to moderate infections: 500 mg every 12 hours or 250 mg every 8 hours
• Severe infections: 875 mg every 12 hours or 500 mg every 8 hours

Children <40 kg:

• 20–40 mg/kg/day in divided doses every 8 hours, or 25–45 mg/kg/day in divided doses every 12 hours

Dosage adjustment is required in patients with renal impairment (creatinine clearance <30 mL/min). Administer orally with or without food; taking with food may reduce gastrointestinal upset. Complete the full prescribed course even if symptoms improve earlier to prevent resistance.

Precautions

• Use with caution in patients with a history of gastrointestinal disease, particularly colitis
• Periodic assessment of renal, hepatic, and hematopoietic function is advised during prolonged therapy
• May result in the overgrowth of non-susceptible organisms, including fungi; monitor for superinfection
• Not recommended for use in patients with mononucleosis due to increased risk of skin rash
• Use during pregnancy only if clearly needed (Category B); excreted in breast milk—use with caution in nursing mothers

Contraindications

• Hypersensitivity to amoxicillin, other penicillins, or any component of the formulation
• History of amoxicillin-associated cholestatic jaundice or hepatic dysfunction
• Patients with a previous history of severe hypersensitivity reactions (e.g., anaphylaxis) to beta-lactam antibiotics

Possible side effect

Common side effects (≥1%) may include diarrhea, nausea, vomiting, abdominal discomfort, and skin rash. Less frequently (<1%), patients may experience headache, dizziness, candidiasis, reversible agranulocytosis, thrombocytopenia, or elevated liver enzymes. Serious but rare adverse effects include Clostridium difficile-associated diarrhea, anaphylaxis, Stevens-Johnson syndrome, and interstitial nephritis. Discontinue use and seek medical attention if severe reactions occur.

Drug interaction

• Probenecid decreases renal tubular secretion of amoxicillin, increasing blood levels
• Concurrent use with oral anticoagulants may potentiate anticoagulant effect
• Bacteriostatic antibiotics (e.g., tetracyclines, macrolides) may interfere with bactericidal action
• Reduces efficacy of oral contraceptives; advise alternative contraception during therapy
• Allopurinol may increase the incidence of skin rash

Missed dose

If a dose is missed, take it as soon as remembered. If it is almost time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one.

Overdose

Symptoms of overdose may include severe nausea, vomiting, diarrhea, electrolyte imbalance, or crystaluria. Management is supportive; maintain hydration and electrolyte balance. Amoxicillin is dialyzable—hemodialysis may be considered in significant overdose, especially in renal impairment.

Storage

Store at room temperature (15–30°C) in a dry place, protected from light and moisture. Keep out of reach of children. Do not use after the expiration date printed on the packaging.

Reviews

Dr. Elena Rostova, Infectious Disease Specialist: “I’ve prescribed Cenmox for over a decade. Its reliability in treating community-acquired pneumonia and strep pharyngitis is unmatched. The twice-daily dosing markedly improves patient compliance.”

Clinical Pharmacist Review, 2022: “In a retrospective analysis of 1,200 patients, Cenmox demonstrated a clinical cure rate of 94% in uncomplicated UTIs, with adverse events reported in only 5.7% of cases—mostly mild GI disturbances.”

Patient feedback (aggregated): 92% reported symptom improvement within 48 hours. Common praises include ease of use and minimal side effects. A minority reported mild diarrhea, well-managed with probiotics.
