Injection guide: week 4
This should be your last 2.5 mg dose. Next week you will increase your dose to 5.0 mg using a new KwikPen. If you’re not ready to increase your dose, contact your healthcare practitioner.
Remove the pen cap from your KwikPen and attach a new pen needle. Then, after priming the pen, inject 2.5 mg once this week. Remove the used pen needle and safely dispose of it in the sharps container.
For a refresher on how to inject using the KwikPen, watch this step-by-step video, or read these instructions.

Prepare to increase your dose next week
Next week you’ll increase your dose to 5.0 mg.
Note: you should not increase your dose if any of the following are true:
- You are still having side effects. This suggests your body needs more time to adjust to the current dose
- You are losing 1-2 pounds per week. This indicates the current dose is still effective.
- You are losing more than 2 pounds per week. This indicates the current dose might be too high.
- You are noticing a decrease in your appetite, less cravings, and feeling full sooner.
If you are experiencing any of the above, contact your healthcare practitioner. If you are experiencing severe side effects, seek in-person care with a healthcare practitioner, or visit a walk-in clinic or the emergency department.
