Accepted answer
28 days past a due dose is 4 half-lives at the seven-day half-life this class runs on, which leaves about 6.3 per cent of that dose still circulating. One line of arithmetic: remaining fraction is one half raised to days over half-life, so 0.5^(28÷7) = 0.0625. At 6.3 per cent the exposure has largely washed out — and the tolerability that the escalation bought washes out with it, which is precisely what a ladder reset exists to protect against. What the product label says and what the pharmacokinetics say are two different answers here, and the first is the one that governs. Restarting, holding or stepping down after a gap is decided under supervision, and nothing here is medical advice.
Start with the interval since the missed dose, because that single number determines the answer.
One missed dose is not a reason to change the schedule or the dose. Two or more is a reason to consider where you are restarting from.
Never take two doses close together to compensate. The peak exposure is roughly doubled, and gastrointestinal tolerability tracks peak exposure closely.
Half-lives across the class span roughly thirteen hours to one week, which is why the answer is agent-specific.
Nothing here is medical advice, and research-use compounds are not approved for human use.
Two or more missed weekly doses means considering a lower restarting step.
