How long before Wegovy pill starts working?

Two different things get called "working". Appetite changes are commonly reported within the first weeks, at doses the label describes as initiation rather than treatment. The weight-loss figure people quote is measured over a full trial at the maintenance dose, which this label does not reach before week 13. A page that answers with one number is answering only one of the two questions.

Can the schedule be moved faster?

That is a prescriber's decision and this page does not advise on it. What the label says is the escalation interval it was studied at; going faster is off-label territory and going slower is common where side effects are hard. The reactions the label lists — nausea, diarrhoea, vomiting, constipation — are typically worst just after a step up.

How long does it take for Wegovy pill to work?

Wegovy pill reaches its maintenance dose no earlier than week 13, because the FDA label steps the dose up on a schedule rather than starting at the dose that does the work. That is 3 months of titration before the dose anyone stays on, across 4 steps, and it is the reason an advertised first-month price says so little. The figure people are usually asking about is the 13.6% mean weight loss its label cites, and that came from Study 7 on the label (NCT05564117), 64 weeks: 13.6% mean weight loss on 25… Appetite changes are usually reported within the first weeks, but the trial figure is measured over its full length rather than at any earlier point — the two are different claims and are often quoted as one. A first year comes to $3,338 once each titration step is priced and the twelve 30-day bottles a year holds are counted.

The schedule, week by week — and what each week costs

Doses and intervals are quoted from FDA prescribing information for WEGOVY (semaglutide) injection and tablets. Prices are the published figure for that dose where the manufacturer prices per step; where it charges one price throughout, the column says so.

When	Dose	A month at this step	What the label notes
Days 1–30	1.5 mg	$149	Starting dosage.
Days 31–60	4 mg	$199	—
Days 61–90	9 mg	$299	—
Day 91 and on	25 mg	$299	The maintenance dosage, and the one this card is scored on.

What “working” is being measured

The number quoted everywhere for Wegovy pill is 13.6% mean weight loss, and it comes from Study 7 on the label (NCT05564117), 64 weeks: 13.6% mean weight loss on 25 mg once daily against 2.4% on placebo, intention-to-treat. That figure is the endpoint of a trial, not a milestone you pass on a particular week — and it is a mean, so half the participants were below it.

Appetite change is the thing most people notice first and it is commonly reported in the early weeks — at doses the label itself calls initiation rather than treatment. Conflating that with the trial figure is how “it works in a week” gets written.

The reactions the label lists in at least 5% of patients — nausea, diarrhoea, vomiting, constipation, abdominal pain — cluster just after a step up rather than at a steady dose. The full label list →
