Missed a Carprofen Dose? Here's What to Do

Published 2026-05-29

Missing a dose of your dog's carprofen happens to almost every owner eventually — a forgotten evening pill, a hectic morning, a bottle that ran out before the refill arrived. Here's exactly what to do, and what not to do.

The Short Answer

If you miss a dose, give it as soon as you remember — unless it's almost time for the next scheduled dose, in which case skip the missed one and resume the normal schedule. Never give a double dose to "catch up." This is the standard general guidance for most once- or twice-daily medications, but always confirm with your vet's office if you're unsure, especially for a dog with any additional health complexity.

Why Doubling Up Is a Real Risk

NSAIDs like carprofen have a defined safety margin between an effective dose and one that raises the risk of GI or organ side effects. Doubling a dose to compensate for a missed one pushes a dog outside the dosing pattern their body — and their vet's calculations — are actually designed around, which is exactly the kind of scenario that can trigger the side effects covered in our side effects guide.

What If You're Not Sure Whether a Dose Was Given?

In multi-person households, this happens more than you'd think — two people each assume the other gave the morning dose. If you genuinely can't confirm whether a dose was given, don't guess by giving another one "just in case." Call your vet's office and describe the situation; they can advise based on your dog's specific medication and health status.

Preventing Missed and Double Doses

• Use a pill organizer, even for a twice-daily medication
• Set a recurring phone reminder for each dose time
• If multiple people in the household give doses, use a shared checklist or note so there's no ambiguity

When a Missed Dose Is More Concerning

An occasional missed dose is rarely a medical emergency for a dog on long-term carprofen for chronic arthritis. It's a different conversation for a dog on a short post-surgical course where consistent inflammation control matters more acutely — if that's your situation, check with your vet's office sooner rather than later.
