20-40 mg/kg/day [child max 1500 mg]
(Formulary dose, by mouth, for a child over 3 months: 20 to 40 mg/kg/day in divided doses every 8 hours, to a maximum of 500 mg per dose, or 25 to 45 mg/kg/day every 12 hours, to a maximum of 875 mg per dose. The same monograph carries a higher line for severe infection given as step-down therapy - 80 to 90 mg/kg/day in divided doses every 12 hours, still capped at 500 mg per dose - and that is the figure the trial the WHO guideline reviewed actually used in severe acute malnutrition. The guideline itself states no amount, so the calculator above shows the ordinary range and both lines are written out here rather than one being chosen silently.)

Egyptian National Drug Formulary - Antimicrobial 2023 (amoxicillin monograph, p338)
Kwashiorkor is severe acute malnutrition with oedema and is treated on the same WHO protocol. WHO recommendation 3.1 states that children with uncomplicated severe acute malnutrition managed as outpatients should be given a course of oral antibiotic such as amoxicillin, and names no amount. The amount here is the Egyptian formulary's general paediatric dose for a child over 3 months.
- THIS IS THE 6 TO 59 MONTH PATHWAY. The guideline behind the card sets its mid-upper-arm-circumference threshold for children of 6 to 59 months and says plainly that the evidence needed to guide treatment in infants under 6 months, and in children of 5 years and over, is not yet there. A severely malnourished infant under 6 months is a different pathway and is not dosed from here.
- THE FORMULARY HAS TWO LINES AND THEY ARE FAR APART. Its mild-to-moderate figure is 20 to 40 mg/kg/day and its severe-infection step-down figure is 80 to 90 mg/kg/day. The calculator shows the first. A child who is septic rather than being covered routinely is a candidate for the second, and that decision is made at the bedside and not from a dose table.
- USE THE SUSPENSION, NOT A CAPSULE. A 7 kg child's daily dose is roughly 140 to 280 mg, which is a fraction of a 500 mg capsule and cannot be divided accurately. The Egyptian register carries the 250 mg/5 mL and 125 mg/5 mL suspensions widely; the brands listed below are the 250 mg/5 mL.
- OEDEMA MAKES THE WEIGHT LIE. The child's measured weight includes the oedema fluid, so a milligram-per-kilogram dose worked from it is an overestimate, and the weight-for-height ratio can look falsely normal. Dose against the programme's assessment, not the scale alone.
- WHO CALLS THE ANTIBIOTIC A CONDITIONAL RECOMMENDATION ON LOW-QUALITY EVIDENCE, and its own wording is "a course of oral antibiotic such as amoxicillin" - the drug is an example, not a mandate.
- THIS IS FOR UNCOMPLICATED DISEASE MANAGED AT HOME. Shock, hypoglycaemia, hypothermia, inability to feed or a serious infection means admission, and the antibiotic is then the ward's choice.
- THE AMOUNT IS NOT WHO'S. WHO names amoxicillin without a dose; the trial it summarises used 80 to 90 mg/kg/day for one week, which is the trial's figure. The dose above is the Egyptian formulary's.
- WHO RECORDS THE ARGUMENT AGAINST IT TOO - the article calls routine antibiotic use in this setting controversial, because of resistance and the effect on the gut microbiome.
- Do not give in serious hypersensitivity to amoxicillin or another beta-lactam.
