Week 13: Titrating Toward 1.7mg
The third dose step on the standard Wegovy schedule. Going from 1.0mg to 1.7mg is the biggest single jump in the titration ladder, and it tends to come with a brief return of side effects before the body adapts again.
Week 13 is when most people on the standard schedule take their first 1.7mg injection. After four weeks at 1.0mg, the body has gotten used to a steady level of medication, and the jump up tends to be felt — appetite suppression often deepens noticeably, and nausea or fatigue can briefly return for a few days before settling.
This is the third and second-to-last titration step. The jump from 1.0 to 1.7mg is proportionally larger than the previous increases, which is part of why side effects can flare. Most people find the new dose tolerable within a week, but going slow on food, fluids, and activity for the first few days is a reasonable approach.
Appetite Suppression
Suppression often deepens noticeably at 1.7mg. Many describe a clearer reduction in food noise compared to the 1.0mg phase.
Weekly loss often picks back up briefly after a titration as appetite drops further and intake follows.
The Week 13 Timeline
The Week 13 Timeline
Day 85 (Injection 13)
First 1.7mg Dose
The first higher dose. Inject as usual and expect the next 48-72 hours to feel a bit more intense than recent weeks.
Days 86-88
Adjustment Window
Mild nausea, lower appetite, and slight fatigue can return briefly. Smaller meals, more water, and lighter activity help most people through this stretch.
Days 89-91
Settling In
By the end of week one at 1.7mg, most users report symptoms calming down and the new appetite baseline becoming the norm.
Navigating Symptoms
Side effect flares after a titration are common and usually short-lived. If symptoms persist beyond a week or are severe, contact your prescriber before the next injection.
What to focus on this week is tolerability, not weight. The number on the scale tends to take care of itself when appetite suppression deepens — the more important task is staying ahead of dehydration, protein intake, and any GI symptoms that pop back up. If the first few days at 1.7mg feel rough, it is not a sign the medication is failing. It is the predictable adjustment phase that follows almost every titration step.
It is also worth being honest with yourself about whether the higher dose is necessary. Some prescribers will hold at 1.0mg longer if response has been strong, and 1.7mg is sometimes used as a maintenance dose rather than a stepping stone to 2.4mg. The standard schedule is a starting point, not a mandate.
What Users Report
“The first 1.7mg shot kicked harder than I expected — a couple of days of nausea, then it smoothed out. By the weekend I was back to feeling like myself, just less hungry.”
— Marcus L.
“I noticed a real shift on day two. The food thoughts that had crept back at 1.0mg quieted down again. Worth the brief adjustment period.”
— Priya N.
Looking ahead
Week 14 is the first full settled week at 1.7mg. The titration shock fades, side effects usually drop back to baseline, and the new dose becomes the new normal. If anything feels off going into next week, log it before your next injection.
