Is an institution required to provide the lot number of the vial of Botox used? They refuse to provide this, I had side effects.

Thank you for your question. I do not believe that a lot number is any secret... If it was requested by a patient I would happily provide the information. Best, 

We do track the lot number of the Botox we inject. In nearly 27 years of injecting Botox I have not had a patient requests this information but I would be glad to share it should such a request be made.

I would have no problem providing this to my patients, side effects from botox are rare.  Best, Dr. Emer.

We typically record the lot number of Botox used in each patient's chart. I would be very suspicious of a practice that would not provide you with the lot number. They're probably using counterfeit product. You can try filing a complaint with Allergan. Maybe they can assist you. Best of luck.

 Thank you for your question and for sharing your concern.  It is routine for a practice to record the lot number. You do have to be careful because there are some counterfeit Botox products out there.
