Step by step
- Step 1Inject under the skin of the stomach, thigh or upper arm on the same day each week.
- Step 2Any time of day, with or without meals.
- Step 3Rotate injection sites. Each pen is single use and the needle is hidden.
Timing
You can change your weekly day as long as there are at least 2 days (48 hours) between doses.
If the next scheduled dose is more than 2 days (48 hours) away, take the missed dose as soon as possible. If it's less than 2 days away, skip it. If you miss more than 2 weeks, ask your prescriber how to restart.
Eating while you take it
Smaller meals, stopping when you're full and going easy on greasy foods can help with nausea. Make protein the first part of each meal: find your protein floor.
