Common dosing patterns (verify protocol)
Dexamethasone dosing varies by indication. This sheet is a reference for calculation and safe dispensing—not a prescription.
| Scenario | Typical pattern | Notes |
|---|---|---|
| Croup | 0.6 mg/kg once (max per protocol) | Many pathways use a max single dose (commonly 10–16 mg). Confirm local max. |
| Asthma / wheeze (protocol-dependent) | Varies by pathway | Use your local regimen (some use 1–2 doses). Don’t substitute without protocol guidance. |
mL conversion (liquid)
Always confirm the bottle concentration. Convert with: mL = mg ÷ (mg/mL).
| Label / concentration | mg/mL | Example: 10 mg dose |
|---|---|---|
| 1 mg/mL | 1 mg/mL | 10.0 mL |
| 0.5 mg/mL | 0.5 mg/mL | 20.0 mL |
Use your local rounding policy and dosing device.
