Child resistant

Unit packaging

On this page11
Eighty percent, not eighty five, because the package only has to be defeated once per dose.

The different rate

Child resistant effectiveness of "not less than 80 percent" for unit packaging, against "not less than 85 percent without a demonstration" for reclosable packaging.

Why the standard treats them differently

A reclosable bottle is a single barrier a child attacks once and then has everything. A blister is a barrier per dose, so getting into one cell is not getting into the package.

Which changes the risk arithmetic

A child who defeats a bottle can take a whole course. A child who defeats one blister cell has one tablet, and the time and effort scale with the quantity.

And resecuring stops being a question

The senior adult test asks about resecuring "if appropriate". For a unit package there is nothing to resecure, which removes the failure mode where a client leaves the cap off.

Which is a real advantage for a dispensed course

An older client who struggles with a push-and-turn cap may do perfectly well with a blister, and the dose is counted for them by the packaging.

It also makes compliance visible

An empty cell is a dose taken. For a client giving a medication to an animal twice a day for ten days, that is a better record than trying to remember.

This shelf does not have it

Blisters and unit-dose packaging are a different manufacturing route entirely, and nothing on this shelf is one. The honest answer is that we serve the bottle route.

Which is worth saying to a clinic

If unit packaging is what the client needs, that is a conversation with a different supplier. Saying so keeps the relationship and loses one line item.

The bottle route has its own strengths

A liquid cannot be blistered, a flexible dose cannot be pre-counted, and a compounded preparation is made per patient. For three of the six leaves here the bottle is the only option.

So match the format to the course

A fixed ten-day course of tablets and a variable liquid dose are different packaging problems, and only the first has two real answers.
