Setup, so nobody has to ask: a 0.5 mL insulin syringe · 15 mg · 1 mg/mL. The units are where I keep going wrong, so please be explicit about them. I have…
For reference: 4 mg · 3 mL. I would like the arithmetic checked rather than the conclusion asserted. I have deliberately not used an online calculator because I want…
Setup, so nobody has to ask: 60 mg · 5 mg/mL. I have worked this out and I would like someone to find the error, because I suspect there is one. My working so far,…
What I have: SURMOUNT-5 · 40 mg. This is presented as though it settles something, and I am not convinced it does. I have two documents that appear to disagree, which…
The specifics, since they change the answer: 4 mg · 2.5 mL · phosphate-buffered diluent. I would like the arithmetic checked rather than the conclusion asserted. I…
The particulars: TRIUMPH-3 · 5 mg. I want to understand what this actually establishes, as opposed to what it is being used to imply. My concern is that I am being…
Numbers first: a U-100 insulin syringe · 2.5 mg · 5 mg/mL. I can do the algebra. I am not confident about the conversion factors. If there is a standard way to lay…
I keep a written log of every draw with date, volume and syringe type. Something has gone wrong and I would like to know how badly before I decide what to do. Nothing…
Details up front: a U-100 insulin syringe · 2.5 mg · 8 mg/mL. I can do the algebra. I am not confident about the conversion factors. If there is a standard way to lay…
The missed-dose instructions in this class are close to each other but not identical, and I cannot work out whether the differences are pharmacology or arbitrary.…
For reference: 4 mg · 1.5 mL · phosphate-buffered diluent · orforglipron. I would like to define my thresholds before I have a result, for obvious reasons. I want a…
For reference: 15 mg · semaglutide. I am at the decision point and I would rather think it through than improvise. I would rather spend money on measurement than on…
What I have: a 0.3 mL insulin syringe · 10 mg · 3.33 mg/mL. I can do the algebra. I am not confident about the conversion factors. If there is a standard way to lay…
I switched to fixed-needle U-100 insulin syringes after reading that dead space costs a fortune with luer fittings, and my yield improved a lot. But I still cannot…
Numbers first: a 0.3 mL insulin syringe · 40 mg · 8 mg/mL. This should be a straightforward calculation and I keep getting two different answers. The numbers are…
What I have: a GLP-1 receptor agonist · 4 mg/mL. This is a planning question. I know what my options are; I do not know how to weigh them. What I want is the minimum…
I understand the single-missed-dose instructions. What I cannot find a clear derivation for is the longer break. The weight-management labels in this class address…
For reference: a 1 mL luer-lock syringe · 60 mg · 3.33 mg/mL. I would rather understand the derivation than memorise the outcome. Two people I asked gave two answers…
The case in front of me: 4 mg/mL · tirzepatide. I would like the axes of comparison first and the recommendation second. I have tried the first option and it works;…
The particulars: liraglutide · ten days. I have read the obvious sources and they disagree with each other, so I would rather ask people who have actually done this.…
Conditions: 2.5 mg · 20 mg/mL. I want the working, not the result — I need to be able to redo it with different numbers. I care about the precision as well as the…
Details up front: STEP 4 · 2.5 mg. This is presented as though it settles something, and I am not convinced it does. I have two documents that appear to disagree,…
The case in front of me: 10 mg · 2.5 mL · 0.9% sodium chloride · cagrilintide. I want to decide this in advance so that I am not deciding it under pressure later.…
What I have: 25 units · 1 mg/mL. I can find plenty of assertions about this and almost no reasoning, which is usually a sign that nobody has checked. Assume no…
