Writing down the date, the dose and the site each week takes fifteen seconds and is the single most useful record anyone here keeps. Memory reconstructs a titration history that never happened.

There is no published evidence about slower escalation because nobody studied it. That means the trials support not going faster and are silent on going slower, which is a different claim from "slower is fine".

The conclusion is tentative; the arithmetic underneath it is not.

The four-week escalation interval is a convention from the pivotal trials, not a pharmacological constant. The pharmacological argument is that with a week-long half-life, four weeks approaches steady state and you can assess the dose fairly. That is an argument for not going faster. It is not an argument against going slower.

Post #61 put the caveat in the right place and I want to underline it.

The most common practical error is not the schedule at all — it is losing track of which step you are on after a break, and then resuming at the top rather than re-approaching it.

That is the version I use. It may not be the version that is correct.

Holding a dose indefinitely: the trials did not study indefinite holding at a non-maximum dose. The trials escalated to a target and then held that. What happens if you stay at an intermediate dose for years is not formally studied and extrapolation is the best available reasoning.

Small point, but it is the one that usually catches people.

m.perrin, post #51: When a dose reduction is the correct response to a side effect: if a side effect is dose-dependent (nausea, constipation, injection discomfort), reducing the dose is a reasonable response. If the side effect is not dose-dependent (e.g., hypoglycemia with insulin), dose reduction does not address the issue. Go to post

Dose equivalence between different incretin analogues is a weak concept. The molecules differ in structure, half-life, receptor selectivity, and in what has been studied clinically. One mg of semaglutide is not equivalent to one mg of something else in any meaningful sense.

t.steenkamp, post #76: Post #75 put the caveat in the right place and I want to underline it. Micro-titration: the concept of increments smaller than the labelled steps. It has no evidence base from trials but is described by some people. The downside is that very small increments are hard to measure accurately with a syringe. Old habit: I write down the… Go to post

The maximum studied dose is a fact about the trial and not a ceiling on the molecule. It is also the last point at which anything is known, which is the reason to treat it as one.

Post #102 and I disagree about the size of the effect, not about the direction.

The starting dose in most of these programmes is a tolerance step and produces little effect by design. Judging the compound at the starting dose is judging the wrong thing.

Second-hand, so weight it accordingly.

Reading it back, the second half matters more than the first.
