Cefixime 500 mg?

Cefixime is an oral cephalosporin antibiotic. A 500 mg strength isn’t the most common presentation in many places (typical adult dosing is often 400 mg per dose), so it’s important to know the exact product and what your clinician prescribed.

If you’re asking about dosing, here are general guidelines (actual dose and duration should come from your prescription label or a clinician, especially if you have kidney problems or other conditions):

- Typical adult dosing (common regimens, varies by infection):
- 400 mg once daily or 200 mg twice daily
- Duration often 5–7 days for throat/tonsillitis or sinusitis; about 7 days for otitis media; 3–7 days for uncomplicated urinary tract infections; single 400 mg dose for uncomplicated gonorrhea (often with another treatment for chlamydia)

- Pediatric dosing (for children):
- Usually 8 mg/kg per day in two divided doses (maximum around 400 mg per day), for infections like throat infections, otitis media, or UTIs. Dosing and duration depend on the specific infection.

- 500 mg strength:
- If your product is 500 mg, that’s less common in many places. The exact dose you should take depends on what your doctor prescribed and the infection being treated. Do not change from what’s on the label without checking with a clinician.

What I can help with next:
- If you share the infection you’re being treated for, your age, and whether you have kidney problems, I can outline the typical dosing ranges you might expect and how long the course usually lasts.
- If you have a prescription with 500 mg tablets, I can help interpret the labeling and whether any adjustments (like splitting doses) are advised.
- I can also list common side effects and important safety notes.

Important safety notes:
- Take as prescribed; finish the full course unless your clinician tells you to stop.
- Tell your clinician about all medications you take (including antacids, iron supplements, and any other antibiotics) because some can affect absorption or interact.
- Seek medical attention if you develop severe diarrhea (possible C. difficile), a severe rash, swelling of the face or throat, or trouble breathing (allergic reaction).

If you can share what infection you’re treating and your age, I’ll tailor the info more precisely.
