Trouble breathing or a swollen tongue?

Emergency help is needed for severe symptoms like trouble breathing or a swollen tongue: call 911 or go to whichever emergency room is nearest.

A severe allergic reaction may develop very fast. A

A common assumption

Does the same name mean the same contents?

Compounded medicines are made to order.

Semaglutide and tirzepatide have approved products for type 2 diabetes or weight loss.

The Food and Drug Administration (FDA) found that some compounded semaglutide and tirzepatide products had false labels.

Some labels gave the names of pharmacies that were not real. B

When compounding is done poorly, medicine may contain germs or too little or too much of the part that treats the illness. C

Ask who made the product and how you can put questions to a pharmacist. Keep the label and delivery information.

A common assumption

Is measurement confusion a small problem?

FDA has received reports of harm after measurement errors with compounded semaglutide injections; some people needed hospital care. D

If the label or instructions are unclear, pause and ask the dispensing pharmacist and prescriber to explain them.

Ask them to check that both sets of instructions agree.

If you may have taken too much medicine, call Poison Control for help.

A common assumption

Must every peptide be kept cold?

Storage depends on the particular product; some peptide medicines are kept at room temperature and others need refrigeration.

Follow that product’s label and the dispensing pharmacy’s storage instructions. E

FDA advises against using a weight-loss injection that requires refrigeration when the package arrives warm or with too little cooling. B

A common assumption

How can I report a medicine problem?

FDA’s MedWatch service lets patients report problems with medicines without paying a fee. F

Reporting a problem does not show that the medicine was its cause. G
