What are morphine milligram equivalents (MME)?

MME is a standardized way to compare the potency of different opioids. It converts any opioid dose to the equivalent dose of oral morphine. CDC guidelines flag daily doses ≥50 MME as requiring careful reassessment and ≥90 MME as high risk for overdose.

Why is renal dose adjustment important?

Many medications are cleared by the kidneys. In patients with reduced kidney function (low GFR), standard doses can accumulate to toxic levels. Renal dose adjustment prevents adverse drug reactions by reducing the dose or extending the dosing interval based on the patient's kidney function.

How do I convert between corticosteroids?

Steroid equivalency is based on anti-inflammatory potency relative to hydrocortisone. For example, 5 mg of prednisone equals 20 mg of hydrocortisone, 4 mg of methylprednisolone, or 0.75 mg of dexamethasone. Our steroid converter handles these conversions automatically.
