Is it likely that a nurse who injected me with filler used syringes that had been used on others?

The number one concern of any medical practice is the health and safety of it's patients. Dermal fillers come prepackaged for single use and we do not store partial filler for later use to avoid any possibility of contamination. I would advise you to meet with your nurse injector to review the notes on your treatment. Product lot numbers are generally documented in the client's record for future treatment reference as well as for inventory control.

Hi Jean,
Thank you for your question - it brings up a very important consumer point.
It is a good idea to educate yourself about what products are being injected and how they are being injected into your body. Your injector should keep records of the product used, including the lot number with expiration date, location, amount of product injected, and whether needle or cannula is used. Any suspected issues during the treatment should also be recorded. Please know that you are fully within your rights to ask for a copy of your treatment record.
In your case it sounds like only two types of filler were used: Juvederm Volift and Teosyal Ultimate. Juvederm syringes are pre-filled to 1 cc. Ultimate can be purchased in both 1 and 3ml syringes. All producers of product recommend injecting only from the original syringe. Some physicians will carefully take product using aseptic technique and transfer the product into smaller syringes; they might then use these different syringes in different patients. Some physicians may take product from the original syringe and blend the product with saline, then filling the product into two sterile syringes. This creates a thinner blend and twice the volume. This process of blending and splitting syringes has been safely utilized for years by many of the worlds best and most respected injectors. You should have knowledge if this process is to be utilized for you and made aware of any potential risks, however small they may be.
No injector in their right mind would ever use the same syringe in two different patients!

Sorry to hear about your experience. I would return and ask this provider to show you the lot numbers that she used. This will let you know which exact products were used. These syringes come pre-filled and should not be "shared" between patients. Technically it would be possible to do this and maintain sterility, but it would be odd. Best of luck, Dr. M
