Not applicable - the protocol is for a child (see the paediatric dose) - Not applicable
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)
WHO recommendation 3.1 states that children with uncomplicated severe acute malnutrition, not requiring admission and managed as outpatients, should be given a course of oral antibiotic such as amoxicillin. The recommendation names the drug and not an amount. The amount printed here is the Egyptian formulary's general paediatric dose for a child over 3 months with a mild to moderate infection, and the two sources are named separately because they answer different questions - WHO says give it, the formulary says how much.
- 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.
- THIS IS FOR UNCOMPLICATED DISEASE MANAGED AT HOME. A child with complicated severe acute malnutrition - shock, hypoglycaemia, hypothermia, an inability to feed, or a serious infection - is admitted, and the antibiotic is then chosen for what is found and given by the ward.
- 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.
- THE AMOUNT IS NOT WHO'S. WHO's recommendation names amoxicillin without a dose. The trial it summarises gave 80 to 90 mg/kg/day for one week, and that figure is the trial's, not a WHO instruction. The dose printed above is the Egyptian formulary's, which is what an Egyptian pharmacy dispenses against.
- WHO RECORDS THE ARGUMENT AGAINST IT TOO. The card's article calls routine antibiotic use controversial, because of antibiotic resistance and the effect on the gut microbiome. It is a WHO recommendation and it is contested.
- SCREEN FOR WHAT IS UNDERNEATH. The article asks for tuberculosis, HIV, sepsis and malaria to be considered in every child with severe acute malnutrition, especially where there is ascites.
- Do not give in serious hypersensitivity to amoxicillin or another beta-lactam.
