Care must be taken to properly convert body weight from pounds to kilograms (1 kg= 2.2 lb) before calculating doses based on body weight. Doses are often expressed as mg/kg/day or mg/kg/dose, therefore orders written "mg/kg/d," which is confusing, require further clarification from the prescriber. Chemotherapeutic drugs are commonly dosed according to body surface area, which requires an extra verification step (BSA calculation) prior to dosing. Medications are available in multiple concentrations, therefore orders written in "m L" rather than "mg" are not acceptable and require further clarification. Dosing also varies by indication, therefore diagnostic information is helpful when calculating doses. The following examples are typically encountered when dosing medication in children. Calculate the dose of amoxicillin suspension in m Ls for otitis media for a 1-yr-old child weighing 22 lb. The dose required is 40 mg/kg/day divided BID and the suspension comes in a concentration of 400 mg/5 m L. Calculate the dose of ceftriaxone in m Ls for meningitis for a 5-yr-old weighing 18 kg. Some clinicians select amoxicillin over penicillin VK to treat odontogenic infection because of a more convenient dosing regimen e.g., 2-3 doses daily for amoxicillin versus 4 doses daily for penicillin VK. Except for coverage of Haemophilus influenzae in acute sinus and otitis media infections, amoxicillin is not any more effective than penicillin VK for the treatment of odontogenic infections. It is less effective than penicillin VK against aerobic gram-positive cocci and similar in efficacy against anaerobes. Thus penicillin VK is the drug of choice for treating odontogenic infections. Contraindications: Hypersensitivity to amoxicillin, penicillin or any component of the formulation. Warnings/Precautions: Use with caution in patients with severe renal impairment (modify dosage); low incidence of cross-allergy with other beta-lactams and cephalosporins exists. The usual daily oral dose for treating odontogenic infections in children is: Children under 12 years: 20-40 mg/kg divided in 2-3 doses daily for 10 days.
Keep using this medicine for the full treatment time, even if you feel better after the first few doses. Your infection may not clear up if you stop using the medicine too soon. The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so. The amount of medicine that you take depends on the strength of the medicine. Take without regard to meals Mixing oral suspension: Tap bottle until all powder flows freely; add approximately one third of the total amount of water for reconstitution and shake vigorously to wet powder; add remainder of water and shake vigorously again After reconstitution, place required amount of suspension directly on child’s tongue for swallowing; if taste is unacceptable, required amount of suspension can be added to formula, milk, fruit juice, water, ginger ale, or other cold drinks; preparation must be taken immediately Shake suspension well before using; any unused portion must be discarded after 14 days Mucocutaneous candidiasis Gastrointestinal (eg, black hairy tongue and hemorrhagic/pseudomembranous colitis, which may occur during or after treatment) Hypersensitivity reactions (eg, anaphylaxis, serum sickness–like reactions, erythematous maculopapular rashes, erythema multiforme, Stevens-Johnson syndrome, exfoliative dermatitis, toxic epidermal necrolysis, acute generalized exanthematous pustulosis, hypersensitivity vasculitis, urticaria) Moderate increase in AST and/or ALT; hepatic dysfunction (eg, cholestatic jaundice, hepatic cholestasis and acute cytolytic hepatitis have been reported) Renal (eg, crystalluria) Anemia (eg, hemolytic anemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia, agranulocytosis) CNS reactions (eg, reversible hyperactivity, agitation, anxiety, insomnia, confusion, convulsions, behavioral changes, dizziness) Tooth discoloration (brown, yellow, or gray staining); may be reduced or eliminated with brushing or dental cleaning Anaphylaxis has been reported rarely but is more likely to occur following parenteral therapy with penicillins Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents; severity may range from mild diarrhea to fatal colitis; CDAD may occur over 2 months after discontinuation of therapy; if CDAD is suspected or confirmed, discontinue immediately and begin appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C difficile, and surgical evaluation Do not administer in patients with infectious mononucleosis because of risk of development of erythematous skin rash Do not administer to patients in the absence of a proven or suspected bacterial infection because of risk of development of drug-resistant bacteria Superinfections with bacterial or fungal pathogens may occur during therapy; if suspected, discontinue immediately and begin appropriate treatment Chewable tablets contain aspartame, which contains phenylalanine Use caution in patients with allergy to cephalosporins, carbapenems Endocarditis prophylaxis: use for only high-risk patients, as per recent AHA guidelines High doses may cause false urine glucose test by some methods Derivative of ampicillin and has similar antibacterial spectrum (certain gram-positive and gram-negative organisms); similar bactericidal action as penicillin; acts on susceptible bacteria during multiplication stage by inhibiting cell wall mucopeptide biosynthesis; superior bioavailability and stability to gastric acid and has broader spectrum of activity than penicillin; less active than penicillin against Streptococcus pneumococcus; penicillin-resistant strains also resistant to amoxicillin, but higher doses may be effective; more effective against gram-negative organisms (eg, N meningitidis, H influenzae) than penicillin The above information is provided for general informational and educational purposes only.
