Children's medication labels give you age. But real pediatric dosing uses weight. Perfect Dose gives your child the accurate dose they need — every single time.
Two children at the same age can weigh 30 pounds different. The label doesn't know that. Your pharmacy's printout doesn't know that. But your child's body does. The FDA removed concentrated infant drops from the market after thousands of parents accidentally overdosed. That's the real stakes.
Enter your child's info, pick your medication, and get a precise weight-based dose in seconds.
Works for every age — From 2 months to adult doses!
Every feature designed for real parents in real situations — not clinical workflows.
Enter weight, get the right dose. Simple and fast — no profile setup required, no accounts, no clutter.
Covers every formulation found in every US pharmacy — so you always know exactly how much to give, whatever you have on hand.
Every recommendation reflects real clinical standards — not a marketing approximation. Developed by a board-certified emergency physician and parent.
Clean, focused interface when you need it most — at 2am with a feverish child. Nothing gets between you and the answer.
Use it straight from your browser. No downloads, no updates, no permissions. Just open the link and go.
Weight-based dosing adjusts with growth — so the dose stays accurate, whether your child weighs 15 lbs or 45 lbs.
"Perfect Dose was born between midnight fevers and middle-of-the-night pharmacy runs. As an emergency physician and father of three, I saw firsthand how hard it is for even the most attentive parents to get medication dosing right. Labels are confusing. Dosing spoons get lost. Every child is different."
