Cautions chapter · Keep the next step clear

# Recognise when to pause or seek help

Ask the health professional treating you about the exact product’s possible harms and what to do if a problem arises. Bring up pregnancy plans and other medicines.

These cautions use facts checked in September 2026.

## Get urgent help for severe allergy symptoms

A serious allergic reaction may become life-threatening and can come on quickly.

Signs of this emergency can include difficulty breathing, difficulty swallowing, or a swollen face or tongue.

For emergency help, dial 911 or head straight to the nearest emergency room.

## A research product is not a care shortcut

FDA

The Food and Drug Administration is the US agency for reviewing medicines.

Research-labelled means marked for laboratory work, rather than approved patient treatment.

The FDA’s advice as of September 26, 2026 is to stay away from weight-loss drugs labelled for research but sold for use in people.

The agency says these drugs may cause harm and that their quality is unknown.

An official-looking seal can be copied or invented; the Federal Trade Commission cautions against treating it as proof.

## Do not guess at an unclear medicine label

Compounded

Made to order, rather than provided as a finished product with approval.

The FDA has received reports of dose mistakes with compounded semaglutide injections, including reports involving hospital care.

The amount of drug and the way the label expresses it can be confusing.

Take your exact product’s label to the pharmacist or prescriber and ask them to explain it. Do not use a web calculation to work it out.

## Storage depends on the product

Pharmacist

The licensed medicine professional you can ask about the product you received.

Cold storage suits some peptide medicines, while room temperature suits others; each product has its own storage rule.

For storage questions, use the label on your exact product and the directions from your pharmacy.

GLP-1 medicines copy the action of a hormone that helps control appetite and blood sugar.

For injectable GLP-1 medicines arriving warm or without enough refrigeration, the FDA advises against using the delivery.

## Report a medicine problem after getting care

Patients can send a medicine-problem report through MedWatch, the FDA’s reporting programme.

Submitting a report puts the concern on record; this is not proof that the event was caused by the medicine.
