Suprax is a prescription-only antibiotic that contains the active ingredient cefixime, a third-generation cephalosporin. It belongs to the antibiotics therapeutic class and is supplied as a pill (tablet) in strengths of 100 mg and 200 mg. In Hong Kong, Suprax is regulated by the Department of Health, Drug Office, and can be dispensed only with a qualified healthcare professional’s prescription.
Cefixime belongs to the β-lactam family of antibiotics. It works by binding to specific penicillin-binding proteins (PBPs) on bacterial cell walls, inhibiting the final stage of cell-wall synthesis. This disruption weakens the wall, leading to bacterial lysis and death. Because cefixime penetrates well into many tissues and fluids, it can treat a broad range of Gram-negative and some Gram-positive organisms. The drug is absorbed orally, reaches peak plasma concentrations within 2-3 hours, and maintains therapeutic levels for about 12 hours, allowing once-daily dosing for many infections.
Suprax (cefixime) is approved in Hong Kong for the treatment of the following infections:
These indications are based on clinical trial data and local regulatory review. The choice of Suprax depends on the infecting organism’s susceptibility and the patient’s clinical situation.
In some clinical settings, cefixime has been investigated for infections not listed on the official label, such as:
These uses are off-label and not approved by Hong Kong’s Drug Office. They should only be considered when a qualified healthcare professional judges that the potential benefits outweigh the risks, and must be accompanied by appropriate monitoring.

Yes. Suprax (cefixime) may be taken with or without food. A high-fat meal can modestly delay absorption but does not affect the overall effectiveness of the medication.
If you remember a missed dose and it is not close to the time of the next scheduled dose, take it as soon as possible. If it is almost time for the next dose, skip the missed one and continue with your regular schedule. Do not double the dose.
Cefixime is classified as Category B2 in Hong Kong, indicating no proven risk in animal studies but lacking adequate human data. It should be used during pregnancy only if clearly needed and after a risk-benefit assessment by a healthcare professional.
Cefixime is not known to interfere with standard workplace or sports drug-testing assays. However, always inform the testing authority of any prescription medications you are taking.
Clinical improvement is often observed within 48-72 hours after starting treatment, although the drug begins to inhibit bacterial growth within a few hours of the first dose.
There are no specific dietary restrictions. However, avoid taking antacids containing aluminum or magnesium within two hours of Suprax, as they can reduce absorption.
Symptoms may include difficulty breathing, swelling of the face or throat, hives, or a sudden rash with blistering. Seek emergency medical care immediately if any of these occur.
Some antibiotics can reduce the effectiveness of hormonal contraception. While cefixime has a low potential for this interaction, using a backup method (e.g., condoms) for at least one menstrual cycle is advisable.
Keep the tablets in their original container, protected from heat, moisture, and direct sunlight. A small insulated pouch can help maintain temperature stability, and always keep the medication out of reach of children.
