How long does it take for orforglipron to work?

Orforglipron reaches its first maintenance dose no earlier than week 9, and the 11.1% average weight loss on Foundayo's label was measured after 72 weeks. Appetite changes are commonly reported within the first weeks, at doses the label describes as initiation rather than treatment; the weight figure is the endpoint of a full trial, not a milestone passed on a particular week.

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, constipation, diarrhea, vomiting — are typically worst just after a step up.

Do I pay for the titration months?

Yes, every one of them. Foundayo is $299 a month at maintenance on this site, and a first year comes to $3,188 once each step is priced and the twelve 30-day bottles a year holds are counted. The months before maintenance are not free trial months; they are billed at the price for that dose.

How long does it take for Foundayo to work?

Foundayo reaches its maintenance dose no earlier than week 9, because the FDA label steps the dose up on a schedule rather than starting at the maintenance dose. That is about 2 months of titration across 2 steps before the maintenance dose, and it is the reason an advertised first-month price says so little. The figure people usually ask about comes from ATTAIN-1, Trial 1 on the label, 72 weeks: 11.1% mean weight loss at 17.2 mg against 2.1% on placebo, intention-to-treat. 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. Every week of that schedule is billed: $299 a month at maintenance on this site, with its source and the date it was read on its price page.

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

Doses and intervals are quoted from FDA prescribing information for Foundayo (orforglipron). 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	0.8 mg daily	$149	Initiation.
Days 31–60	2.5 mg daily	$149	—
Days 61–90	5.5 mg daily	$199	The first dose the label does not require you to leave: escalation is mandatory up to here, and every step above is optional, on response and tolerability.
Day 91 and on	9 mg → 14.5 mg → 17.2 mg	$299	One step at a time, at least 30 days apart, on response and tolerability.

What “working” is being measured

The number quoted everywhere for Foundayo is 11.1% mean weight loss, and it comes from ATTAIN-1, Trial 1 on the label, 72 weeks: 11.1% mean weight loss at 17.2 mg against 2.1% 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 an average across everyone in the trial, so individual results sit on both sides of 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, constipation, diarrhea, vomiting, indigestion — cluster just after a step up rather than at a steady dose. The full label list →

How much weight by month 3 or 6?

No figure for Foundayo earlier than week 72 is printed in its label or in the trial's ClinicalTrials.gov record, and this site does not read numbers off a graph — so it has none to give before the endpoint above.
