Amoxicillin is used to treat many different types of infection caused by bacteria, such as tonsillitis, bronchitis, pneumonia, gonorrhea, and infections of the ear, nose, throat, skin, or urinary tract. Amoxicillin is also sometimes used together with another antibiotic called clarithromycin (Biaxin) to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer called lansoprazole (Prevacid). There are many brands and forms of amoxicillin available and not all brands are listed on this leaflet. Do not use this medication if you are allergic to amoxicillin or to any other penicillin antibiotic, such as ampicillin (Omnipen, Principen), dicloxacillin (Dycill, Dynapen), oxacillin (Bactocill), penicillin (Beepen-VK, Ledercillin VK, Pen-V, Pen-Vee K, Pfizerpen, V-Cillin K, Veetids), and others. Before using amoxicillin, tell your doctor if you are allergic to cephalosporins such as Omnicef, Cefzil, Ceftin, Keflex, and others.

Amoxicillin Johns Hopkins ABX Guide

Amoxicillin is indicated for the treatment of the following infections in adults and children (see section 4.2, 4.4 and 5.1). • Acute bacterial sinusitis • Acute streptococcal tonsillitis and pharyngitis • Acute exacerbations of chronic bronchitis • Community acquired pneumonia • Acute otitis media • Acute cystitis • Acute pyelonephritis • Asymptomatic Bacteriuria in pregnancy • Typhoid and paratyphoid fevers • Dental abscess with spreading cellulitis • Prosthetic joint infections • Helicobacter pylori eradication • Lyme disease Amoxicillin is also indicated for the prophylaxis of endocarditis. Consideration should be given to official guidance on the appropriate use of antibacterial agents. The dose of Amoxicillin that is selected to treat an individual infection should take into account: • The expected pathogens and their likely susceptibility to antibacterial agents (see section 4.4) • The severity and the site of infection • The age, weight and renal function of the patient; as shown below The duration of therapy should be determined by the type of infection and the response of the patient, and should generally be as short as possible. Some infections require longer periods of treatment (see section 4.4 regarding prolonged therapy). Children may be treated with Amoxicillin capsules, dispersible tablets, suspensions or sachets. Amoxicillin Paediatric Suspension is recommended for children under six months of age. Therapy can be started parenterally according to the dosing recommendations of the intravenous formulation and continued with an oral preparation. Hypersensitivity to the active substance, to any of the penicillins or to any of the excipients listed in section 6.1. Before initiating therapy with amoxicillin, careful enquiry should be made concerning previous hypersensitivity reactions to penicillin and cephalosporins or other beta-lactam agents (see sections 4.3 and 4.8). 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.
