Questions to work through
Ask about the quality of the preparation.
Food and Drug Administration is the agency’s name, shortened to FDA.
Germs or other unwanted material can get into a medicine through poor compounding, FDA warns. Poor preparation can also put the working ingredient into the medicine in an amount that is too high or too low.
That ingredient is called the active ingredient.
Get the storage instructions for that product.
Some peptide medicines require cold storage; room temperature is right for other products. Follow the instructions for your exact medicine.
Ask the pharmacy to explain the label rather than using a general peptide-storage rule.
Ask how to avoid getting the amount wrong.
Reports received by FDA describe mistakes with the amount of compounded semaglutide injected, with hospital care needed in some cases. These reports were checked September 26, 2026.
Bring an unclear instruction to the prescriber or pharmacist and ask for an explanation.
When help is urgent
For health reading, MedlinePlus comes from the National Library of Medicine.
A severe allergic reaction needs emergency help because it can be life-threatening, MedlinePlus explains.
Listed signs include collapse, swelling in the face or tongue, and difficulty swallowing or breathing.
MedlinePlus directs readers with severe allergic symptoms to emergency help, including the nearest emergency room.
Keep personal questions in the visit
Ask about pregnancy, breastfeeding, other medicines and anything in your health history that may matter to the proposed plan. Ask how a new problem would be assessed.
