What are Foundayo steps? The six dose levels explained

Six strengths, two very different phases. The first three are a fixed starting sequence. The last three are options your prescriber chooses between, and nobody is required to reach the top one.

0.8 mg
2.5 mg
5.5 mg
9 mg
14.5 mg
17.2 mg

Steps 1 to 3 (plain) are a fixed sequence with a minimum of 30 days at each. Steps 4 to 6 (highlighted) are prescriber-selected maintenance options, not a queue. Last reviewed 31 August 2026.

The short answer

Foundayo steps are the six tablet strengths used in treatment: 0.8mg, 2.5mg, 5.5mg, 9mg, 14.5mg and 17.2mg. Steps 1 to 3 are taken as a fixed starting sequence, with a minimum of 30 days at each strength before moving up. Steps 4, 5 and 6 work differently: they are maintenance options a prescriber selects between based on how you respond, rather than a ladder everyone must climb to the end.

The two phases, and why the difference matters

Most explanations present all six strengths as one continuous staircase, implying treatment means climbing steadily until you reach 17.2mg. That is not how the dosing is structured, and the misunderstanding causes real anxiety: people assume they are behind schedule, or that stopping at a middle strength means the treatment has failed them.

Steps 1 to 3: the fixed starting sequence

These three are taken in order, with a minimum of 30 days at each strength before moving to the next. The purpose is tolerability rather than effect. Gut side effects cluster around starting and around each increase, and holding at each strength for a month gives your body time to adapt before the next change.

  • Step 1, 0.8mg — introduction. Minimal weight change here is normal and not a warning sign.
  • Step 2, 2.5mg — still building. Appetite suppression often becomes noticeable.
  • Step 3, 5.5mg — the first strength at which trials recorded meaningful results.

Steps 4 to 6: prescriber-selected maintenance options

After the starting sequence, these three are alternatives rather than a queue. A prescriber selects between them according to how you have responded, what side effects you are experiencing and what you are trying to achieve. Some people stay at Step 4 indefinitely. Some move to Step 5 and stop. Some never leave Step 3. All are legitimate outcomes.

  • Step 4, 9mg — a very common maintenance strength.
  • Step 5, 14.5mg — a further option where more effect is needed.
  • Step 6, 17.2mg — the maximum authorised strength, and the source of the headline trial figures.

17.2mg is not a finish line

There is no clinical requirement to reach the highest strength, and treating it as a target misreads how the dosing works. The aim is the lowest strength that gives you the result you need with side effects you can live with. If that is 5.5mg, treatment is working exactly as intended. Higher strengths generally bring more side effects alongside more effect, which is precisely the trade-off a prescriber weighs when selecting a maintenance step.

What decides your step

  • How you are responding. Steady progress at a given strength is a reason to stay, not to climb.
  • Side effects. A prescriber can hold you longer or move you back down. That is a normal adjustment, not a failure.
  • Your wider health. Other conditions and medicines feed into the decision.
  • Time at the current step. The 30 day minimum applies to the starting sequence; later changes follow assessment rather than a timetable.

Rules that apply at every step

  • One tablet a day, maximum. Never two, for any reason.
  • Never change your own step. Escalation and reduction are prescriber decisions.
  • Never combine with another GLP-1 medicine.
  • Missed a dose? See our missed dose guide. Missed several days, speak to your prescriber before restarting, because tolerance fades during a break.
  • Swallow tablets whole, at any time of day, with or without food.

Why steps matter when comparing prices

Pharmacy pricing is usually set per step, and higher strengths commonly cost more. Two practical consequences follow. First, a cheap Step 1 price tells you little about your ongoing cost, so budget for the step you expect to settle at. Second, discount offers are frequently weighted towards Step 1 to attract new patients: the Farmeci code is a clear example, giving 27% off a first order at Step 1 but 10% at any later step.

Our retail price list is built step by step for this reason, and the cheapest Foundayo guide explains what else to compare.

Frequently asked questions

What are Foundayo steps?

The six tablet strengths used in treatment: 0.8mg, 2.5mg, 5.5mg, 9mg, 14.5mg and 17.2mg. Steps 1 to 3 form a fixed starting sequence with a minimum of 30 days at each. Steps 4 to 6 are maintenance options a prescriber selects between.

How many Foundayo dose steps are there?

Six.

Do I have to reach 17.2mg?

No. It is one of several maintenance options, not a target. Many people remain on a lower step permanently, and the goal is the lowest effective strength for you.

How long is each step?

A minimum of 30 days at each of the first three steps. Later steps are held or changed according to prescriber assessment rather than a fixed schedule.

What if I miss a step or take a break?

Talk to your prescriber before restarting. Tolerance can fade during a gap, so they may ask you to restart lower rather than resume where you left off.

Can I ask to move up faster?

You can raise it, but the minimum intervals exist for tolerability and a prescriber will not shorten them on request alone. Moving faster generally means more nausea, not faster results.
