Steps

schema.org/HowTo

01
Weigh the child in kilograms (lb divided by 2.2).
02
Multiply weight in kg by 4.4 mg to get the dose; cap at 200 mg total.
03
Example: a 20 kg child gets 88 mg; a 50 kg child gets 200 mg.
04
Doxycycline can be given to children of any age for tick-borne illness; current AAP and CDC guidance no longer restricts short courses by age.
05
Confirm the exact dose with the prescribing clinician; pharmacies typically dispense the suspension or split tablets.
