The British National Formulary for Children (BNFC) guidance recommends oral antibiotic dosing according to age bands as a proxy for weight. Recommended doses of amoxicillin for children were increased in 2014 ‘after widespread concerns of under dosing’. However, the impact of dose changes on British children of different weights is unknown, particularly given the rising prevalence of childhood obesity in the UK. We aimed to estimate the accuracy of oral amoxicillin dosing in British children before and after the revised BNFC guidance in 2014. Interventions We calculated the doses each child would receive using the BNFC age band guidance, before and after the 2014 changes, against the ‘gold standard’ weight-based dose of amoxicillin, as per its summary of product characteristics. Primary outcome measure Assuming children of different weights were equally likely to receive antibiotics, we calculated the percentage of the children who would be at risk of misdosing by the BNFC age bands.
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.

There is only one medication that I know of where the FDA approves of doubling the dose of an antibiotic and that is a Z-Pack or azithromycin. However in your case although as another contributor eluded to with regards to initial dosing, follow how it is prescribe and do not be cavalier and experiment. Amoxicillin dosing is to be taken three times daily or every eight hours. It can also be taken twice daily however that is dependent upon if you have regular amoxicillin, or amoxicillin with clavulanic acid which is normally dosed twice daily. Certainly, and most importantly if you are asking a question like this in this forum seeking information about taking prescribe medication that would be ill advised. Rather, you should be asking this question to the person who prescribe this medication to you namely your primary care doctor who can provide you the most accurate in safest answer. Amoxicillin is a very common drug used to treat a wide variety of bacterial infections. These can include, but are not limited to, sinus-based issues, skin, and genital infections. Amoxicillin is frequently paired with other drugs to treat different types of bacteria that may be more severe or react to a specific type of antibiotic. Amoxicillin is used as an antibiotic treatment for a wide range of illnesses. The most common include ear, nose, and throat infections. In larger doses Amoxicillin can be used to treat infections on the skin, in the urinary tract, and the genitals. The antibiotic can also be combined with other drugs to treat bacterial infections stemming from H. Those who are allergic to cephalosporin or penicillin should avoid taking Amoxicillin. Allergic reactions to the antibiotics can be severe so it is vital that you seek medical attention immediately if you begin to feel the effects of one coming on.
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. Children 12 years 10-15 mg/kg/dose every 4-6 hours as needed maximum 90 mg/kg/24 hours,3. Usual oral dosage1,2 based on amoxicillin component.
