How to track Botox lot numbers by patient

By the CorvexMed team. Published 7 October 2026.

If a patient asks which vial you used, or a manufacturer issues a notice about a batch, you need to find the answer in minutes. That is only possible if the lot number was written down at the time of the injection.

What to record for every treatment

• Patient name and the date of the treatment
• Product name and the lot number from the vial or box
• Expiry date of that lot
• Units or volume used, and where on the face or body
• Who performed the treatment
• Consent status for that treatment

Why the expiry date matters as much as the lot

Lots on a shelf are not equal. A vial that expires next month should be used before one that expires in six. Without a list of lots and dates, staff pick whatever is at the front, and older stock is wasted.

Where paper and spreadsheets break down

• The lot is written on a sheet that is filed by date, not by lot, so finding every patient who received one lot means going through the pile.
• Nobody checks the expiry at the moment of choosing the vial.
• Stock counts drift because units used are not deducted anywhere.

A simple routine

1. Keep a stock list with one line per lot: product, lot, expiry, units on hand.
2. Pick the lot that expires first among those still valid.
3. Write the lot against the patient before the vial is opened.
4. Deduct the units used the same day.
5. Once a month, count the shelf against the list.

CorvexMed does steps two to four for you: it blocks expired lots, suggests the earliest valid one, and deducts units when the session is done. See lot and expiry tracking.
