Ceftin is a brand-name medication that contains the active ingredient cefuroxime axetil. It belongs to the antibiotics class, specifically the second-generation cephalosporins. Ceftin is manufactured as an oral pill and is available in two strengths: 250 mg and 500 mg tablets. In Hong Kong the product is classified as a prescription-only medication and is regulated by the Department of Health.
Cefuroxime axetil is a prodrug of cefuroxime. After the tablet is swallowed, intestinal enzymes convert the axetil moiety into the active cefuroxime molecule, which is then absorbed into the bloodstream.
Cefuroxime exerts its antibacterial effect by binding to penicillin-binding proteins (PBPs) on the bacterial cell wall. This binding blocks the final stages of peptidoglycan synthesis, weakening the cell wall and causing bacterial lysis. As a second-generation cephalosporin, cefuroxime has a broader spectrum against gram-negative organisms than first-generation agents, while retaining activity against many gram-positive bacteria.
Key pharmacologic points:
Ceftin is approved in Hong Kong for the treatment of several bacterial infections, including:
These indications reflect the drug’s activity against common pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and many strains of Escherichia coli.
These effects usually resolve without intervention. Maintaining adequate hydration and taking the tablet with food can reduce gastrointestinal discomfort.
If you are taking prescription medicines, over-the-counter drugs, supplements, or herbal products, inform your healthcare professional before starting Ceftin.
Standard adult dosing:
250 mg tablet taken twice daily (every 12 hours), or
500 mg tablet taken twice daily. The exact dose and duration depend on the infection being treated and should be prescribed by a qualified healthcare provider.
Administration tips:
Swallow the tablet whole with a full glass of water.
It may be taken with food to enhance absorption and reduce stomach upset.
Do not crush or chew the tablet unless specifically advised.
Missed dose: Take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. Do not double the dose.
Overdose management: Symptoms may include nausea, vomiting, and diarrhea. Seek emergency medical care; supportive treatment and hydration are the mainstays.
Discontinuation: For short courses, stopping abruptly is acceptable. For prolonged therapy, a healthcare provider may recommend tapering to prevent rebound infection.

Ceftin can be taken with or without food, but a high-fat meal improves its absorption. Taking the tablet with food may also lessen mild gastrointestinal upset.
Treatment duration varies by infection, ranging from 5 days for uncomplicated respiratory infections to 10-14 days for more serious or deep-tissue infections. Your prescriber will set the appropriate length.
Cefuroxime is not a substance screened for in standard employment or athletic drug-testing panels, as it is an antibiotic, not a performance-enhancing or illicit drug.
If you realize a missed dose while away from home, take it as soon as possible unless the next dose is due within a few hours. In that case, skip the missed dose and continue with the regular schedule; do not double-dose.
Both strengths contain the same active ingredient; the 500 mg tablet simply delivers twice the amount of drug per tablet. Choice of strength depends on the infection severity and the dosing schedule prescribed.
While cross-reactivity between penicillins and cephalosporins exists, it is relatively low with second-generation agents like cefuroxime. However, anyone with a known severe penicillin allergy should discuss risks with their healthcare provider before using Ceftin.
Current evidence does not indicate that cefuroxime reduces the effectiveness of hormonal contraceptives. Nonetheless, it is prudent to use a backup method if you experience vomiting or severe diarrhea while on the antibiotic.
Limit excessive alcohol consumption, which can irritate the stomach, and avoid taking antacids containing magnesium or aluminum within two hours of the dose, as they may slightly reduce absorption.
Yes. Completing the full course ensures that all pathogenic bacteria are eradicated and helps prevent the development of antibiotic resistance.
Bathrooms are often humid and experience temperature fluctuations. It is better to keep Ceftin in a cool, dry place such as a kitchen cabinet or a drawer away from moisture.
