Sirolimus monitoring planner (what the label says to check)
Renders the label's monitoring rules as a timeline: whole-blood trough checks and their timing, the LAM target range, the lab panel the warning sections imply (lipids, glucose, urine protein, blood counts), and the half-life arithmetic that sets the tempo. Education only: it schedules nothing and orders nothing.

Published records (7 of 7)
| What | When | Why |
|---|---|---|
| Sirolimus whole-blood trough | At least 3 to 4 days after loading dose(s); after any dose change; with hepatic impairment; when interacting drugs start or stop | Label recommends therapeutic drug monitoring for all patients; drug rides in red cells so plasma levels mislead |
| Trough target in LAM | Dose adjusted to 5 to 15 ng/mL | The label's own target range for the LAM indication |
| Lipid panel | Periodically during therapy | Label warning: cholesterol and triglyceride increases requiring treatment occurred more often on sirolimus |
| Glucose | Periodically during therapy | Hyperglycemia and new-onset diabetes appear in the label's adverse-reaction experience |
| Urinary protein | Periodic quantitative monitoring recommended | Label proteinuria warning, strongest around conversion from calcineurin inhibitors |
| Blood counts | Periodically during therapy | Anemia appears among common reactions; the 1 mg/day pilot in older adults saw small red-cell decrements |
| Steady-state awareness | About 11 to 13 days after any regimen change (derived: 4 to 5 half-lives at 62 hours) | Levels drawn before steady state under- or over-state the new regimen |
Every row restates a published record; sources resolve on the sourced monograph. Species is part of the data: this table never scales an animal dose into a human figure.
Worked example
Worked example: why day-3 troughs, not day-1
Half-life is about 62 hours (label). After a loading dose, the label says to check troughs at least 3 to 4 days later, once distribution has settled. After a maintenance change, approximate steady state needs 4 to 5 half-lives: 4 x 62 = 248 hours (10.3 days); 5 x 62 = 310 hours (12.9 days). So the planner displays 'about 11 to 13 days' before a level reflects the new regimen.
Step by step
- Pick the scenario.
- Read what the label monitors and when.
- Note the steady-state arithmetic before judging any level.
- Bring the table to the prescriber; this page orders nothing.
Frequently asked questions
Do longevity protocols need labs at all?
Every studied population had them: the label recommends TDM for all patients, and even PEARL monitored blood biomarkers throughout its 48 weeks. An off-label protocol with zero labs matches no studied protocol.
Why whole blood instead of plasma?
Sirolimus concentrates in red cells (blood-to-plasma ratio about 36), so whole-blood troughs are the label's measurement of record.
How fast do levels respond to a dose change?
With a 62-hour half-life, approximate steady state takes about 11 to 13 days, which is why the label times checks in days, not hours.
