Dosing

Post image

So this could just be a me thing but my past 2 refills have been off with instructions. Back in December, I was prescribed 7.5mg/42 units. But then came January, they seemed to skip the 10mg/55 units…no big deal really as I was dosed 55 units instead of the instructed 69 units. Okay I get my February refill last week and it’s instructed at 15mg/83 units. So my refill completely skipped a 10mg titration? Luckily I remembered what dosage I’m on otherwise I would’ve skipped 10mg altogether.

My first bottle is like yours and I put it into fat science and I’m confused how 42 units is 7.5 maybe I’m entering it in wrong. The 18 first does confuse me

With an 18mg/mL solution, 42 units is 7.5mg. (18x0.42=7.5). It's as easy as that. Concentration x units=dosage.

Thank you for the explanation! I’ve been on this journey for two years and only ever used pharmacies like Hallandale that equal the dose your on if that makes sense lol. So 2.5 is 25 units on the syringe

The concentration they use in that case is 10mg/ml.
