Can you use keflex for a sinus infection?

Keflex (cephalexin) is an antibiotic that is effective in treating various bacterial infections, including those involving the respiratory tract. While it is commonly used to treat sinus infections, its suitability depends on specific circumstances and the causative bacteria. For sinus infections, healthcare professionals are advised to rely on evidence-based prescribing guidelines to determine the appropriate antibiotic treatment.

It's crucial to consult a healthcare provider to assess your specific condition and prescribe the most suitable medication for your sinus infection based on several factors such as the underlying cause, your medical history, and any potential allergies or drug interactions. Self-treating or adjusting your medication can be hazardous and may not lead to effective symptom relief, or worse, cause additional health concerns.
