What to avoid
A prescription leaves room for questions about harm.
The misconception
“Having a prescription settles every concern about a product.”
The answer
A prescription for a pharmacy-made drug does not mean the Food and Drug Administration (FDA) has checked it. Before a compounded drug goes on sale, FDA does not check its quality, how well it works or whether it is safe. That remained FDA’s position when checked on September 26, 2026.
Compounded means made by a pharmacist, doctor or registered facility. Ask about the drug itself as well as the prescription.

“For research purposes” on a product offered as treatment
Words such as “not for human consumption” can appear on products still marketed for personal use. Another warning label is “for research purposes”. FDA warns against these unapproved weight-loss products: they may harm you, and their quality is unknown.
This warning was checked September 26, 2026.
No clear pharmacy identity
FDA found compounded tirzepatide and semaglutide with false pharmacy details on the label. Some pharmacies were made up; others were real but had not made that medicine.
These findings were checked September 26, 2026.
Check the pharmacy recordInstructions borrowed from a different product
Storage depends on the drug; some need to stay cold and others do not.
Have the pharmacist go through the label for your own product with you. A different drug’s storage notes cannot fill that gap.
A delivery that raises questions
For weight-loss shots that need to stay cold, FDA advises against using them if delivery is warm or cooling is inadequate.
Ask the dispensing pharmacy to address the delivery and the product’s storage instructions.
When the question is urgent
A severe allergic reaction can threaten life, says MedlinePlus; its listed signs include trouble breathing and sudden tongue swelling.
Its advice is urgent: seek emergency help for severe signs, by contacting emergency services or going to an emergency room.
Do not wait on a routine message when urgent help is needed.
