CloseDose helps families make confident, safe dosing decisions.
We created CloseDose to demystify pediatric medication dosing with tools that feel trustworthy, accessible, and easy to use — no matter the hour or the device.
Why CloseDose exists
Parents and caregivers told us that dosing over-the-counter medicines often feels overwhelming. Between varying bottle concentrations, fast-changing guidance, and countless online charts, it can be hard to know what information to trust.
CloseDose combines clinical expertise with thoughtful design so caregivers can quickly calculate accurate, age-appropriate doses — and understand the reasoning behind each recommendation.
