Also known as: Amoxicillin
Amopen is one of the best forms of antibiotic available today. It is used to treat infections caused by certain bacteria, including: infections of the ear, nose, and throat (pneumonia, bronchitis); infections of the genitourinary tract; infections of the skin and skin structure; infections of the lower respiratory tract; gonorrhea, acute uncomplicated (ano-genital and urethral infections) in male and females.
Amopen is also used before some surgery or dental work to prevent infection. It is also used in combination with other medications to eliminate H. pylori, a bacteria that causes ulcers. Amopen may also be used for other purposes not listed here.
Amopen acts by inhibiting the synthesis of bacterial cell wall and stopping the growth of bacteria.
Amopen is available in capsules.
Amopen is usually taken every 8 hours (three times a day). It can be taken with or without food.
The chewable tablets should be crushed or chewed thoroughly before they are swallowed. The tablets and capsules should be swallowed whole and taken with a full glass of water.
Take Amopen exactly as directed. Do not take more or less Amopen or take it more often than prescribed by your doctor. Do not stop taking Amopen without talking to your doctor. To clear up your infection completely, continue taking Amopen for the full course of treatment even if you feel better in a few days. Stopping Amopen too soon may cause bacteria to become resistant to antibiotics.
Adults: 500 mg PO every 12 hours or 250 mg PO every 8 hours for mild/moderate infections and 875 mg PO every 12 hours or 500 mg PO every 8 hours for severe infections.
Infants 6 months and older, Children, and Adolescents: 80 to 90 mg/kg/day PO in divided doses every 12 hours is recommended by the American Academy of Pediatrics (AAP) as first-line therapy. Do not exceed 500 mg/dose if given every 8 hours or 875 mg/dose if given every 12 hours. AAP recommends a 10-day course for any child with severe disease and for all patients less than 2 years of age, regardless of severity. For children 2 to 5 years with mild to moderate disease, a 7-day course is acceptable. For children 6 years and older with mild to moderate disease, a 5- to 7-day course is acceptable. The FDA-approved dosage is 20 mg/kg/day PO in divided doses every 8 hours (Max: 250 mg/dose) or 25 mg/kg/day PO in divided doses every 12 hours (Max: 500 mg/dose) for mild to moderate infections and 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) for severe infections.
Infants 4 to 5 months: 80 to 90 mg/kg/day PO given in divided doses every 12 hours for 10 days was recommended by experts as first-line therapy in previous guidelines ; however, this age group is not addressed in the most current guidelines by the American Academy of Pediatrics (AAP). The FDA-approved dosage is 20 mg/kg/day PO in divided doses every 8 hours or 25 mg/kg/day PO in divided doses every 12 hours for mild to moderate infections and 40 mg/kg/day PO in divided doses every 8 hours or 45 mg/kg/day PO in divided doses every 12 hours for severe infections.
Infants 3 months and younger: 30 mg/kg/day PO given in divided doses every 12 hours is the general FDA-approved dosing. Young infants are less capable of responding to infection, and the clinical manifestations of infection can be subtle. Because of the increased risk for complications of an undiagnosed systemic infection, every young infant presenting with a fever should be carefully evaluated.
In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures as required. If the overdosage is very recent and there is no contraindication, an attempt at emesis or other means of removal of drug from the stomach may be performed. A prospective study of 51 pediatric patients at a poison-control center suggested that overdosages of less than 250 mg/kg of Amopen are not associated with significant clinical symptoms and do not require gastric emptying.
Interstitial nephritis resulting in oliguric renal failure has been reported in a small number of patients after overdosage with Amopen.
Crystalluria, in some cases leading to renal failure, has also been reported after Amopen overdosage in adult and pediatric patients. In case of overdosage, adequate fluid intake and diuresis should be maintained to reduce the risk of Amopen crystalluria.
Renal impairment appears to be reversible with cessation of drug administration. High blood levels may occur more readily in patients with impaired renal function because of decreased renal clearance of Amopen. Amopen may be removed from circulation by hemodialysis.
