Flumox 500 and 1000: Uses, Dosage, and Side Effects

Amoxicillin is a widely used beta-lactam antibiotic, while flucloxacillin is a penicillinase-resistant penicillin designed to remain active against certain bacteria that produce beta-lactamase. Both interfere with bacterial cell-wall synthesis.

Active ingredients and strengths

IngredientClassMain point
AmoxicillinPenicillin / beta-lactamActive against a range of susceptible bacteria.
FlucloxacillinPenicillinase-resistant penicillinParticularly useful against selected susceptible staphylococci.

Flumox is sold in different total strengths, including products labeled 500 mg or 1000 mg in some markets. The total number alone is not enough to compare products; the amount of each antibiotic matters.

What is Flumox used for?

  1. Selected bacterial respiratory infections.
  2. Bacterial otitis media, sinusitis, tonsillitis, or pharyngitis when the organisms are susceptible.
  3. Some skin and soft-tissue infections.
  4. Selected genitourinary infections based on clinical assessment and local resistance patterns.

Flumox dosage

Dose and treatment duration depend on the infection, severity, age, kidney function, and formulation. A 1000 mg product is not automatically “better” than a lower strength; the appropriate strength is determined by the clinical situation.

Should Flumox be taken with food?

Amoxicillin can generally be taken with or without food, but food may reduce flucloxacillin absorption. Follow the directions for the exact combination product and prescription rather than applying the rule for one ingredient alone.

Side effects and allergy warnings

Possible side effects include diarrhea, nausea, vomiting, abdominal discomfort, and skin rash. Because both ingredients are penicillins, serious allergy is an important risk. Breathing difficulty, facial swelling, or a severe rash requires urgent medical care. Severe or persistent antibiotic-associated diarrhea should also be assessed.
