Key Takeaways
- Standard initiation is 2.5 mg once weekly, then 5 mg after 4 weeks.
- Escalation typically occurs in 2.5 mg steps with at least 4 weeks at each level.
- Maintenance ranges are commonly 5 mg, 10 mg, or 15 mg based on response and tolerability.
- Do not self-adjust dose or interval without provider guidance.
Decision Checklist
Use this quick table to pressure-test fit before taking action.
| Criterion | What to Verify | Why It Matters |
|---|---|---|
| Routine Fit | Can this plan work on busy, imperfect weeks? | Routine durability predicts adherence quality |
| Safety Signals | Expected vs urgent symptoms are clearly explained | Improves response speed and reduces avoidable risk |
| Support Access | Clear path for questions between formal check-ins | Faster feedback usually prevents dropout spirals |
| Continuity Plan | Month-2 and month-3 expectations are explicit | Turns short-term trial behavior into stable execution |
Practical dosing chart (educational)
This chart summarizes common labeled escalation logic, but your personal schedule should be individualized by your treating provider.
- Weeks 1-4: 2.5 mg once weekly
- Weeks 5-8: 5 mg once weekly
- Then: consider 7.5 mg, 10 mg, 12.5 mg, and up to 15 mg, each after at least 4 weeks
- Maximum commonly referenced weekly dose: 15 mg

How providers decide whether to escalate
Escalation decisions are usually based on a balance of tolerability and clinical response, not a rigid race to the highest dose.
If side effects remain disruptive, providers may hold at a lower dose longer before moving up.
If tolerability is stable and response is insufficient, escalation may be appropriate within the standard framework.

Missed-dose handling should follow prescribing guidance and your provider instructions. Rules depend on how many days have passed since the missed injection.
Keep a stable weekly schedule and rotate injection sites as instructed to improve consistency and reduce avoidable confusion.

Common dosing mistakes to avoid
A slower, provider-guided plan is usually safer and more sustainable than unstructured dose experimentation.
- Escalating too quickly after early mild side effects
- Changing dose based on social media anecdotes
- Treating temporary appetite changes as proof a dose is wrong
- Ignoring persistent tolerability issues without clinical follow-up
