If I am allergic to Revolax lip fillers can I try other brands?

Hi Cheerful5525,
Fillers can contain a variety of compounds, some of which can rarely cause reactions or side effects in some patients. If you experienced a negative reaction to Revolax, you should ask your physician about other alternatives that contain different compounds. Hyaluronic acid-based fillers are usually well-received as the body produces this compound naturally. However, keep in mind that not all fillers produce the same results, so you should consult with an experienced facial plastic surgeon to find the best alternative.
Kind regards,
Dr Julian De Silva

Yes, I would recommend trying HA based fillers such as Juvederm or Restylane. See an expert to review your case for formal recommendations. Best, Dr. Emer. 

Revolax is an inexpensive over the counter filler that is cross linked. It is also not legal to inject this filler in the States as it is not FDA approved. Doing a test of the filler (even elsewhere) can be a good idea. This way you verify that you're not allergic to a specific filler. If you do not have a reaction then you may proceed to have the filler injected at a later day.
