Problems & help

What can go wrong, and where to turn

The possible harms depend on the product. Start with its name and ask what is known about it.

These product facts and problem reports reflect September 2026.

An injection needs a quality check too

FDA is the Food and Drug Administration. FDA has told sellers that a shot can carry germs and poisonous substances past some of the body’s defences. It says serious harm may follow.

Poor compounding can leave germs in a medicine or give it the wrong strength. Compounding means making a medicine to order.

FDA does not check a made-to-order medicine’s quality, harms or benefit before sale.

Ask for instructions about your particular product

Storage for peptide medicines varies: some require cold conditions, while others stay at room temperature. The rules depend on the product.

Errors involving custom semaglutide shots may have caused harm described in reports received by FDA. Some people needed hospital care.

A drug’s advice for pregnancy and breastfeeding is tied to that product. Made-to-order medicines lack the same FDA-reviewed information.

Severe allergic symptoms need urgent help

Breathing trouble, swelling of the tongue or face, or passing out may warn of a severe allergic reaction.

MedlinePlus calls the reaction an emergency that threatens life. The guide’s publisher is the National Library of Medicine in the U.S.

For severe symptoms, its advice is to call for emergency assistance or seek care at an emergency room.

You can report a medicine problem

You can report a medicine problem through MedWatch, FDA’s free reporting service. Both patients and health professionals can send reports to it.

A report alone does not prove that the medicine caused harm. Nor can the reports show how often a problem happens.
