Compounding map / the reason for the change
What makes compounding a different route?
When a pharmacist or doctor makes a drug to order, that work is called compounding.
FDA means Food and Drug Administration. It reviews approved drugs. Making a drug to order is a different route.
September 2026 rules for medicines prepared to order.
A reason for your care versus a cheaper headline
A change for your need
Federal law limits routine copying of available medicines. A changed medicine may qualify for an exception. For a named patient, the prescriber must determine that changing the medicine makes a meaningful difference.
Ask what changed and why it matters for you.
A routine copy
Under the September 2026 rules, pharmacies or doctors making a drug for a named patient cannot routinely copy an available medicine or make unusually large amounts of those copies.
A cheaper price alone does not qualify for the exception that requires a meaningful change for the named patient.
Ask for the medical reason as well as the cost.
Even a lawfully made-to-order drug has no FDA approval.
Read the records behind this ↓What changed for weight-loss copies?
FDA’s list of national shortages included neither semaglutide nor tirzepatide in September 2026.
A shortage list records a lack of supply across the country.
Nevada’s June 2025 notice told pharmacies to stop making copies of semaglutide and tirzepatide shots because the national shortages had ended. It still points to exceptions for drugs that do not count as copies.
That notice is not a ban on every made-to-order version of semaglutide in Nevada.
One local pharmacy running out does not put the drug back on FDA’s national shortage list. The special rules allowing copies during a national shortage do not return just because of that local problem.
Does adding a vitamin change the answer?
FDA said in its September 2026 record that semaglutide with added vitamin B12 may still count as essentially a copy.
“Essentially a copy” means the medicine is close enough to an available drug for the copying limits to apply. Adding a vitamin does not by itself show a meaningful change for the named patient.
Ask the person writing the prescription what health need the change addresses for you.
Who can check the pharmacy side?
As of September 2026, Nevada requires pharmacies to follow federal rules for the ingredients they use to make medicines.
The working ingredient must meet official drug-quality standards where those exist. Otherwise it must be part of an approved drug or be on the federal list of extra allowed ingredients. A certificate must give the ingredient’s test results, and the ingredient’s maker must have FDA registration.
FDA does not check the made-to-order drug’s safety, quality or effect before it is sold.
Ask for the pharmacy’s name and which of those ingredient checks it meets. Keep that answer with the reason for changing your medicine.
