Cephalexin for Sinus Infections — What We Published in May 2024
This month we focused on one clear question: can cephalexin help with sinus infections? Our main post, “Cephalexin for Treating Sinus Infections: Effectiveness and Insights,” explains how the drug works, who might benefit, common side effects, and practical tips so you know what to expect if this medicine comes up in a doctor’s plan.
Cephalexin is a first‑generation cephalosporin antibiotic. It kills certain bacteria by interfering with cell wall formation. That makes it useful against some strains that cause sinusitis, especially when the culprit is a susceptible bacterial species. It’s not a magic fix for every case, though — knowing when bacteria are likely responsible matters.
Clinical guidance often favors amoxicillin or amoxicillin‑clavulanate for typical acute bacterial sinusitis. Cephalexin can be an option when those aren’t suitable, for example if a patient has specific allergies to penicillins or when local bacterial patterns suggest cephalexin may work. Our article explains that choice clearly so you can bring a smart question to your clinician.
Typical adult dosing commonly used is 250–500 mg every 6–12 hours, with treatment length ranging from about 5 to 14 days depending on severity and clinical response. Kidney function matters: people with reduced kidney function often need dose adjustments. Don’t change doses on your own — talk to your prescriber about the right schedule.
Side effects are usually mild but worth watching. The most common are stomach upset, diarrhea, and skin rashes. Yeast infections can happen after antibiotics. Rarely, serious allergic reactions occur; seek immediate care for hives, swelling, or breathing trouble. Our post lists warning signs so you know when to stop the drug and call for help.
When to contact a doctor
Get medical attention if symptoms don’t improve after 48–72 hours on antibiotics, if high fever develops, or if you have severe facial pain, swelling around the eyes, or vision changes. Also check in when symptoms last longer than about 10 days without improvement — that could mean a different diagnosis or need for specialist input.
Practical tips we recommend
Finish the prescribed course even if you feel better, unless advised otherwise. Take cephalexin with food if it upsets your stomach. Tell your provider about allergies and all current medicines — for example, some antibiotics can interact with blood thinners. If sinus infections recur, ask about nasal cultures or an ENT referral to find an underlying cause.
