Blepharitis, also known as blepharitis, is treated with penicillins or cephalosporins as prescribed by the patient’s doctor. Blepharitis is an acute inflammation caused by purulent bacteria invading the glands of the eyelids, most commonly Staphylococcus aureus infections, with localized treatment as the mainstay, and if the patient develops systemic inflammation, the patient may be prescribed penicillin or cephalosporin medication. Cephalosporin cefazolin kills bacteria by inhibiting bacterial cell wall synthesis, and penicillin amoxicillin capsules kill bacteria by interfering with bacterial cell wall mucopeptide biosynthesis. Patients with blepharitis can also use antibiotic eye drops, such as levofloxacin hydrochloride eye drops, tobramycin eye drops, etc., as prescribed by the doctor, to control the local inflammation of the eye and promote the recovery of the condition. It is recommended that patients with blepharitis consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
