Mild nausea possible. Most people tolerate this starter dose well with minimal disruption.
Eat smaller, more frequent meals. Stay well hydrated. Inject on the same day each week to build a routine.
Nausea may increase. Appetite suppression becomes noticeable. Some experience constipation or mild headaches.
Avoid high-fat or greasy foods. Keep bland snacks on hand (crackers, toast). Ginger tea can ease nausea.
GI side effects peak for many patients. Significant appetite changes. Nausea, diarrhea, or constipation possible.
This is often the hardest phase, it gets better. Prioritize protein at every meal. Talk to your provider if symptoms are severe.
Body is adapting. Side effects typically improving. Continued strong appetite suppression.
Focus on nutrient-dense foods since you are eating less. Light exercise (walking 20-30 min) helps digestion and mood.
Full therapeutic dose. Most side effects have resolved. Steady-state weight loss continues.
This is your maintenance dose. Continue healthy habits. Regular check-ins with your provider every 3-6 months.
Frequently Asked Questions
What happens if I miss a dose of my GLP-1 medication?
For weekly injectables (Wegovy, Ozempic, Zepbound/Mounjaro), take the missed dose as soon as you remember if there are at least 2 days (48 hours) until your next scheduled dose. If less than 48 hours remain, skip it and take your next dose on schedule. For daily Rybelsus, skip the missed dose and resume the next day. Never double up on doses.
Can I skip the titration schedule and start at a higher dose?
No. Skipping titration significantly increases the risk of severe nausea, vomiting, and other GI side effects. The gradual dose increase allows your body to adjust to the medication. Clinical trials used these specific schedules for safety reasons. Always follow your provider's prescribed titration plan.
How long does it take to see weight loss results?
Most people notice appetite changes within the first 2-4 weeks. Measurable weight loss typically begins by weeks 4-8. Clinical trials show the majority of weight loss occurs in the first 6-12 months, with Wegovy patients losing an average of 15% body weight and tirzepatide patients losing up to 22% by 72 weeks.
What should I do if side effects are too severe at a dose level?
Contact your prescribing provider. They may extend your time at the current dose level before increasing (e.g., staying at 0.5 mg for 8 weeks instead of 4), temporarily reduce your dose, or suggest supportive measures like anti-nausea medication. Do not adjust your dose on your own.
Do I stay on GLP-1 medication forever?
Current evidence suggests that most people regain weight if they stop GLP-1 medication entirely. The STEP 1 extension trial showed participants regained about two-thirds of lost weight within a year of stopping semaglutide. Most providers recommend long-term maintenance, though some patients may be able to reduce to a lower dose. Discuss your long-term plan with your provider.
The rest of the Wegovy schedule, and what it costs at each step
The June 2026 label added a 7.2 mg option and the daily tablet, neither of which is in the timeline above. Novo also prices the pen by strength, so the number moves as you climb.
