When the rise starts late

Delayed ON

The point at which the response begins to rise after a dose is pushed later than it usually is.

In the graph

An example curve from a day that took a long time to come up The horizontal axis runs from 06:00 to 14:00. The vertical axis is how well the body is moving, relative to that person's own range — higher is better movement. Doses are marked at 07:00. Starts to rise around 08:35, Highest point around 09:35. higher lower 07:00 06 08 10 12 14 Starts to rise 08:35 Highest point 09:35 An example curve from a day that took a long time to come up The horizontal axis runs from 06:00 to 14:00.

  • Response through the day
  • Reference curve, for comparison
  • Time a dose was taken
An illustration generated for teaching. It does not represent the response to any particular medication or dose, and real curves differ from person to person.

What to look at on the curve is not the height of the peak but the distance between the dose marker and the point where the curve begins to rise.

The dotted line above is a reference curve, drawn for comparison. Both curves have a dose at the same time, but the solid one stays low for a while before coming up late. After a late rise the peak may end up similar to the reference curve, or lower.

That gap does not survive on memory alone. The impression that it was slow today stays with you, but how many minutes it took fades, and within a few days it blurs into other days. Noting the dose time and the moment things started to change, as they happen, is what lets you look back later at how the gap varies through a day and whether it repeats from day to day.

People often put it like this

  • It takes ages after the dose before my body loosens up
  • The morning dose is especially slow
  • It used to take thirty minutes, now it is over an hour
  • Just as I give up on it, it suddenly kicks in

Things often discussed alongside it

These are factors that come up in conversation about this pattern. This is not a list of confirmed causes, and more than one of them is often in play at once.

  • Emptying from the stomach into the small intestine may have been slower that day.
  • A meal, particularly one high in protein, may have fallen close to the dose.
  • The actual time of the dose may have differed from the time you remember.
  • Conditions on the day such as sleep, hydration or activity may have been at work alongside it.

Worth writing down alongside this pattern

  • The time the dose was actually taken Noting it at the moment, rather than from memory, is what makes the gap exact.
  • The time you felt it start to come up For this pattern the moment things began to change matters more than the peak.
  • The best moment and how high it got This separates a late but full rise from one that stayed low.
  • Meals before and after, and what they were A meal time alongside the dose time shows the relationship between them.
  • Which dose of the day it was This shows whether it only happens at certain times of day.
  • Whether the same thing repeats across days A single day rarely tells you. It takes several before it shows.

What you could show your care team

A record is material for describing your situation. Decisions about which medication you take, at what dose, and at what time belong with the clinicians who look after you.
