Antibiotic Treatment for Large, Swollen Maxillary Gland

First-Line Treatment Options

The American College of Physicians recommends amoxicillin-clavulanate as the first-choice antibiotic for maxillary sinusitis, which commonly presents with swelling and pain in the maxillary area, with a standard dosing for adults of 7-10 days 1, 2
The typical symptoms of maxillary sinusitis include unilateral or bilateral infraorbital pain that increases when the head is bent forward, sometimes pulsatile and peaking in the early evening and at night, in patients with suspected bacterial infection 3
For children, the recommended dosage is amoxicillin-clavulanate 80 mg/kg/day in three doses, not exceeding 3 g/day, for a duration of 7-10 days 4, 2

For patients with penicillin allergy, the Infectious Diseases Society of America recommends second-generation oral cephalosporins such as cefuroxime-axetil, third-generation oral cephalosporins such as cefpodoxime-proxetil or cefotiam-hexetil, and pristinamycin as alternative treatment options 1, 2

The standard duration of treatment is 7-10 days for adults, with cefuroxime-axetil and cefpodoxime-proxetil demonstrating efficacy with a shorter 5-day course, according to the Clinical Microbiology and Infection guidelines 1, 2
For children, the standard duration is also 7-10 days, as recommended by the American Academy of Pediatrics 2

The American College of Physicians recommends reserving fluoroquinolones active against pneumococci, such as levofloxacin and moxifloxacin, for situations with high risk of complications or failure of first-line therapy 1, 2
Immediate antibiotic therapy is indicated in severe acute forms of purulent maxillary sinusitis, and for maxillary sinusitis of dental origin, according to the Infectious Diseases Society of America 2, 3

Clinical signs suggestive of complicated sinusitis requiring hospitalization include meningeal syndrome, exophthalmos, palpebral edema, ocular mobility disorders, and severe pain preventing sleep, as indicated by the Clinical Microbiology and Infection guidelines 1, 2, 3
These complications require parenteral antibiotic therapy and immediate referral to hospital, according to the American College of Emergency Physicians 3

For acute sinusitis, the American Academy of Allergy, Asthma, and Immunology recommends 500 mg of cefuroxime axetil twice daily for 10-14 days in adults 5, 6
The American Academy of Otolaryngology suggests that for some cases of upper respiratory tract infections, a shorter course of 5 days may be effective, although this is not universally recommended 5, 6

Cefuroxime axetil 500 mg twice daily has been shown to have similar efficacy to amoxicillin-clavulanate 875/125 mg twice daily in the treatment of acute and chronic sinusitis, with a strength of evidence rated as high 6, 7
The Infectious Diseases Society of America notes that cefuroxime axetil is an appropriate option for the treatment of post-viral sinusitis when antibiotics are necessary, with a moderate strength of evidence 5, 8

For patients who do not respond to initial treatment with amoxicillin after 3-5 days, the American Academy of Allergy, Asthma, and Immunology recommends cefuroxime axetil as an alternative, with a moderate strength of evidence 9
The American Academy of Otolaryngology suggests that in cases of recurrent or chronic sinusitis, a longer course of treatment may be necessary, with a low strength of evidence 6, 7

The Infectious Diseases Society of America recommends evaluating the response to treatment after 3-5 days and considering a change in antibiotic or further investigation if there is no improvement, with a high strength of evidence 9
The American Academy of Allergy, Asthma, and Immunology suggests completing the full course of antibiotics even after resolution of symptoms to prevent relapse and development of resistance, with a high strength of evidence 9
