Safety primer · identity, source, follow-up
Safety begins before a product arrives
The package looks neat. The harder questions are what is inside, where it was made, and who will respond if something goes wrong.
Picture this
A prescription, a pharmacy whose name and licence you can look up, and a named person to contact afterward give you facts that a mystery package cannot.
Know which product it is
The FDA does not review a compounded medicine before it is sold. The agency does not first confirm that it is safe, that it works, or that its quality holds up. The pharmacy, prescription, and reason for the custom product all belong in the record.
Injection adds another concern
FDA has told peptide sellers that an injected product can pass some of the body’s guards against germs and toxins. That is why injectable medicine must be made sterile, meaning free of germs, under a national standard called USP chapter 797. You can ask the pharmacy whether it follows that standard and check its California sterile-compounding licence.
Plan for a problem
Keep the label, the name of the pharmacy that filled it, your visit record, and the way to reach your clinician together. A patient can report a medicine problem through FDA MedWatch.
