Restarting after a long gap: what the labelling implies posts 31–47

This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

On post #27 — agreed on the reasoning, with one qualification.

Titrating on symptoms rather than on the calendar is what most people here actually do. It is defensible, it is not what was studied, and describing it as the protocol would be wrong.

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

Concentration and dose get conflated constantly in this subcategory. Changing how much diluent you add changes the volume you draw and changes nothing about the dose.

That holds for the case as described. Change the assumptions and it may not.

That reframing is the whole thing. The facts I already had.

t.verhoeven, post #19: Titrating on tolerability rather than on the calendar: some people escalate when they tolerate a dose well, others escalate on the prescribed schedule regardless. The published trials used a calendar-based schedule. Tolerability-based escalation has no formal evidence base but is not uncommon in practice. Go to post

Doubling after a miss adds a peak for no gain and is not what any labelling in this class recommends. That is a description of the labelling rather than advice about anyone's situation.

I am not the right person to answer the follow-up to this.

a.eriksen, post #15: 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. Go to post

That is one dataset and I would not build a rule on it.

Research-use-only material is not a licensed product and no labelling covers it. Everything in this subcategory about published schedules describes what was done in trials of licensed formulations.

The answer changed when I changed how I was measuring, which was informative.

Post #35 is right about the mechanism and I think understates the practical bit.

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.

Same conclusion as the reply above, reached differently, which is mildly reassuring.

This is the answer, and the reason it is the answer is the more useful part.

Post #39 is right about the mechanism and I think understates the practical bit.

Splitting a weekly dose in two: the pharmacokinetic argument against is that you want the benefit of long half-life, which gives a slowly changing plasma level from a weekly dosing schedule. Splitting it flattens the curve further but loses the convenience of once-weekly dosing. The trade-off is convenience versus a slightly flatter concentration curve.

Posting it because the silence on this was starting to look like agreement.

Half steps are arithmetically simple and pharmacologically unstudied. They are not dangerous in any obvious way and they are also not what the evidence describes, and both halves of that should be said.

This follows post #44 rather than contradicting it.

Concentration and dose get conflated constantly in this subcategory. Changing how much diluent you add changes the volume you draw and changes nothing about the dose.

Reading it again, the caveat matters more than the finding.
