Zepbound injection site log and call sheet

Record each weekly injection, where it went and what the skin did afterwards, measured in centimetres and dated, so a call about a lump, spreading redness or itching starts from facts. The label's allergy warning signs and site-rotation instructions sit on the same page.

From the Zepbound label

  • Use a different injection spot every week; staying in the same body area is fine as long as the exact spot changes.[1]
  • In the weight trials, injection site reactions were reported by 6% to 8% of people on Zepbound and 2% on placebo.[1]
  • People who developed antibodies to tirzepatide had site reactions and allergic-type reactions more often.[1]
  • Zepbound should not be used after a serious allergic reaction to tirzepatide or any of its ingredients.[1]

Stop Zepbound and get medical help right away

  • Swelling of your face, lips, tongue or throat, or problems breathing or swallowing.[1]
  • Severe rash or itching, fainting or feeling dizzy, or a very rapid heartbeat.[1]

Have ready if a site reaction is not settling

Questions for your prescriber

  1. Does this look like a local reaction, an infection or an allergy?
  2. Should I avoid this body area for a while?
  3. Is anything in my injection technique worth changing?
  4. Would a different device or formulation make sense for me?
  5. If it has not cleared, when should I call back or be seen?
