Can an Emergency Room Do Anything About Severe Swelling from Juvederm Injections?

An ER may be able to help you, but it will take longer to sort it out and it will definitely be more costly. You will be better served by the provider that injected your Juvederm in the first place.  You may need require a steroid to reduce the swelling but you may also need some hyaluronidase if the Juvederm has caused a vascular compromise to the lips.  You need to seek medical attention immediately.

If you can go back to your orginal doc that's fine but if it is after hoursd I would go to your local emergenvy room.Thay can give you soem IV meds to control the reaction.

There are a few reasons why lips swell after juvederm injection. First is a swelling response to being "stuck" with a needle. Next is bleeding that can occur since there is a large vein and artery in the lip. For delayed swelling, sometimes hyaluronic acid products absorb fluid at a later date, but that is more common around the eyes.

If the lip turns dark and very painful right after injection, that is the only emergency.
As for treatment, the best person to address swelling is the doctor who did the injection. They know where and how much was injected. Emergency room doctors don't generally perform filler injections and might not be the best person to treat the side effects.
