The patient’s need matters
Pharmacies could not regularly make almost identical copies of a ready-made medicine that was already available. This rule was checked in September 2026.
When a pharmacy prepares medicine for an individual patient, the rule permits a change that makes an important difference for that patient. The person ordering the medicine must decide that the difference matters.
One possible reason to use a custom medicine is an allergy to a ready-made product’s dye.
A lower price does not count as the important difference required by this rule.
Semaglutide and tirzepatide are medicines used for weight or blood-sugar problems.
Neither semaglutide injections nor tirzepatide injections appeared on the FDA’s national shortage list when checked on 26 September 2026.
Ask: what is the reason for this custom product in my case?
