It’s been more than three-quarters of a year since I wrote about medicating one of our resident felines. Yes, Wiley’s done well and continues act like his old self – thanks for asking! His weight’s dropped about a quarter pound from a year ago. Our vet raised an eyebrow at that change, “cats his age usually gain and gain,” but I think it’s because he’s much more relaxed. That, and the two-year-old almost-kitten gives him a run for his money. Wiley recently turned ten.
Anyway, I ran into a situation the other day that calls for some comment.
It was time to renew Wiley’s prescription. I buy a 30-tablet bottle – the quarter-tablet doses last 120 days. But when I cracked the seal something was different: these tablets were somewhat smaller and lacked the usual blue coating.
I first checked the veterinarian’s label. It was correct but now I needed to see the manufacturer’s label beneath. Over-labels are notoriously difficult to remove, I suppose in the name of abuse prevention, but removal CAN be accomplished with patience and perseverance.
I learned that the origin of this latest bottle was India and not the United States. (The cost was $2.10 less expensive, too.)
The label told me that per-tablet dose hadn’t changed. But the tablet mass was clearly different. Now I needed to re-weigh and re-calculate my capsule fills. Here’s where it got weird.
I won’t bore you with the 30-tablet list, but the variance between tablets quickly became clear. The smallest and largest measurements were 0.099 g and 0.107 g! Tablets from the US were way more consistent, tablet-to-tablet.
The average worked out to 0.1023 g, yielding a quarter-tablet dose of 0.0256 g. This would be near the lower end of the capabilities of my scale: 20 grams with milligram resolution.
I’m pleased to report that my first 12-day compounding run worked out perfectly. Finished capsules are less full than usual, naturally.
But I’ll still be bringing my feedback to the vet.
Wiley’s only been using the new batch for a few days now so it’s too early to tell if this change will have any effect on him. It should not, but you never know.
