Amoxicillin medication

Depending on the causative organism, definitive therapy may range from 45 to 100 mg/kg/day PO in divided doses.[46963] In HIV-infected patients, amoxicillin is recommended as part of combination therapy for outpatients.[34362] 90 mg/kg/day PO in divided amoxicillin and doxycycline together for pneumonia doses every 8 to 12 hours (Max: 4 g/day).[46963] Dividing 90 mg/kg/day into 3 doses/day increases the probability for reaching a clinical and microbiological cure to 90% compared with the same daily dose divided into 2 doses/day (65%) in patients with pneumococcal pneumonia (MIC of 2 mcg/mL).

For less resistant pneumococcal strains (MIC of 0.5 mcg/mL), dividing 90 mg/kg/day into 2 doses will likely achieve a clinical and microbiological cure in more than 99% of children.[51856] Consider the addition of a macrolide for patients 5 years and older who do not have clinical, laboratory, or radiologic evidence amoxicillin 500mg capsule uses to distinguish bacterial CAP from atypical CAP. Depending on the causative organism, definitive therapy may range from 45 to 100 mg/kg/day PO in divided doses.[46963] 500 mg PO every 12 hours or 250 mg PO every 8 hours. The Infectious Diseases Society of America (IDSA) does not recommend amoxicillin for empiric use due to the antimicrobial resistance. 20 mg/kg/day PO given in divided doses every 8 hours (Max: 250 mg/dose) or 25 mg/kg/day PO given in divided doses every 12 hours (Max: 500 mg/dose).

30 mg/kg/day PO given in divided doses every 12 hours. 875 mg PO every 12 hours or 500 mg PO every 8 hours.

The Infectious Diseases Society of America (IDSA) does not recommend amoxicillin for empiric use due to the antimicrobial resistance. 40 mg/kg/day PO in divided doses every 8 hours (Max: 500 mg/dose) or 45 mg/kg/day PO in divided doses every 12 hours (Max: 875 mg/dose). 30 mg/kg/day PO given in divided doses every 12 hours. The IDSA recommends 500 mg PO 3 times per day for 14—21 days in the absence of neurological symptoms.

A double-blind, randomized trial compared amoxicillin (without probenecid) with azithromycin in patients with erythema migrans. Those treated with amoxicillin were significantly more likely than those treated with azithromycin to achieve complete resolution by day 20, the end of the study.

Significantly more azithromycin recipients relapsed than amoxicillin recipients.

The dose of amoxicillin in this study was 500 mg PO 3 times per day for 20 days.

The IDSA recommends 50 mg/kg/day PO in divided doses every 8 hours for 14—21 days.

Amoxicillin 250—375 mg PO three times daily with metronidazole (250 mg PO three times daily) for 7—10 days. 2 g PO as a single dose given 30 to amoxicillin for pimples 60 minutes before procedure. Prophylaxis is recommended for at-risk cardiac patients undergoing dental procedures that involve manipulation of gingival tissue, manipulation of the periapical region of teeth, or perforation of the oral mucosa.

Cardiac patients that are considered to be at highest risk include those with prosthetic cardiac valves or prosthetic material used for cardiac valve repair, previous infective endocarditis, select types of congenital heart disease (CHD), and cardiac transplantation with valvulopathy.

50 mg/kg PO as a single dose (Max: 2 g/dose) given 30 to 60 minutes before procedure.

Cardiac patients that are considered to be at highest risk include those with prosthetic cardiac valves or prosthetic material used for cardiac valve repair, previous infective endocarditis, select types of congenital heart disease (CHD), and cardiac transplantation with valvulopathy. For acute infections, 50—100 mg/kg/day PO in 3 to 4 divided doses for 14 days.

For chronic carriers, 100 mg/kg/day PO in 3 to 4 divided doses plus probenecid (1 g/day PO for adults or 23 mg/kg/day PO for children) for 6 weeks. 1,000 mg PO twice daily in combination with clarithromycin (500 mg PO twice daily) and lansoprazole (30 mg PO twice daily) for 10 to 14 days is recommended. Clarithromycin-containing regimens are associated with a high eradication rate and less side effects than regimens that include metronidazole. 1,000 mg amoxicillin capsule 500 PO twice daily with clarithromycin (500 mg PO twice daily) and omeprazole (20 mg twice daily) for 10 to 14 days.

For patients with an active ulcer, an additional 14 days of omeprazole (20 mg once daily) is recommended for ulcer healing.

According to ACG, any standard dose PPI may be substituted for omeprazole in this regimen.

More effective triple drug regimens are available and recommended.

The original FDA-approved dual regimen consists of amoxicillin 1,000 mg PO and lansoprazole (30 mg PO), each given three times daily for 14 days.

Clinical trials showed eradication rates of about 70%, which is substantially lower than that achieved with triple-drug therapy regimens; triple-drug therapy was shown to be more effective than all possible dual therapy combinations.

1,000 mg PO twice daily with metronidazole (500 mg PO twice daily) and omeprazole (20 mg twice daily) for 10 to 14 days. For patients with an active ulcer, an additional 14 days fish amoxicillin petco of omeprazole (20 mg once daily) is recommended for ulcer healing.

According to ACG, any standard dose PPI may be substituted for omeprazole in this regimen. A prospective, open label study evaluated the effectiveness of levofloxacin-based dual (levofloxacin/rabeprazole) and triple (levofloxacin/amoxicillin/rabeprazole) therapy in eradicating H.

Patients (n = 160) were randomized into 4 groups (3 dual and 1 triple therapy regimen). The dual regimens consisted of levofloxacin 500 mg PO once daily with rabeprazole (20 mg PO once daily) for 5, 7, or 10 days. The triple regimen included amoxicillin 1,000 mg PO twice daily, levofloxacin (500 mg once daily), and rabeprazole (20 mg once daily) for 7 days.

Triple therapy resulted in a significantly higher eradication rate (more than 90%) than dual therapy at any duration (70% or less).

25 mg/kg/dose PO twice daily (Max: 1 g/dose) with metronidazole (10 mg/kg/dose PO twice daily [Max: 500 mg/dose]) and a proton pump inhibitor (PPI; 1 to 2 mg/kg/day PO divided every 12 hours [Max: 20 mg/dose]) for 1 to 2 weeks. 25 mg/kg/dose PO twice daily (Max: 1 g/dose) with clarithromycin (10 mg/kg/dose PO twice daily [Max: 500 mg/dose]) and a proton pump inhibitor (PPI; 1 to 2 mg/kg/day PO divided every 12 hours [Max: 20 mg/dose]) for 1 to 2 weeks.

25 mg/kg/dose PO twice daily (Max: 1 g/dose)

For a bioterrorism-related event, treat for a total duration of 60 days. Following initial treatment for severe anthrax infection, amoxicillin as a single agent may also be used as follow-up treatment.

75 mg/kg/day PO divided every 8 hours (Max: 1 g/dose) as an alternative for penicillin-susceptible strains. Treat for 7 to 10 days for naturally acquired infection. For a bioterrorism-related event, continue treatment for 60 days.

As oral follow-up combination therapy after initial IV therapy for severe anthrax (non-CNS infection), use amoxicillin in combination with a protein synthesis inhibitor (i.e., clindamycin, doxycycline, linezolid).

Continue therapy to complete a treatment course of at least 14 days; additional prophylaxis to complete an antimicrobial course of up to 60 days may be required.
