Botox: Eyes swell for 10 days. Is that an allergy?

eyelid swelling can be a result of different causes- sinus problems unrelated to Botox- allergic contact dermatitits to numbing cream applied prior to Botox- forehead droop brining the upper eyelids down with the eyebrows after Botox relaxed the forehead lifting muscles too much-allergic reaction to a product in Botox is very rare and if occurs would be possibly more generalized than limited to the area of treatment.please see your provider for an evaluation as they know where they inserted your BotoxThe information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.  The information provided should not be relied upon as a substitute for consultations with a qualified health professional who may be familiar with your individual medical needs

It is difficult to say without looking at a photo, but typically, what people think is swelling is increased laxity of the lower eye lids or drooping of the upper eyelids due to Botox weakening the muscles. If you have itching and changes to the skin, it could be an allergy. Make sure your doctor is aware that this happened so that they can look at it at determine if you are sensitive to the Botox.

Yes,  unfortunately,  that can happen,  flu- like, cold-like or  seasonal allergy-like   symptoms can occur. some people  get  swollen eyes, runny nose,  slight fever chills and sweats  too. It  will go  away. 

Without photos, it is difficult to answer your question. However swelling can occur after any injection and this does not sound like an allergic reaction. I would follow up with your injector to determine if the swelling you believe is occurring is actually heaviness in the brow which can occur when Botox is not placed appropriately. Best wishes,

Hi.  I would follow up with the injecting doctor.  It would be very unusual for Botox to cause drooping of the eyelids for 6 months as it wears off by 3-4 months.  The swelling is also quite unusual.  There is a possibility of being allergic to Botox if you are allergic to egg whites.  Botox degrades completely by 3-4 months so any effects like this should subside by then if you are having a reaction to the product.  You could try Xeomin in the future.  Do follow up with your doctor on this. 

10 days of swelling and/or an allergic reaction is not expected after botox injections. It is best to be evaluated by the injector and physician to determine the cause of your swelling. It is also not standard for your eyelids to droop after Botox when injected correctly. It is important to see an experienced injector for safe and effective treatments.

it does not sound like a typical allergy to Botox. I would continue doing what it is you're doing and make sure that your eyelids Do not drop like they did the first time you had you treatment because it is possible the treatment was performed to close do the eyelid. It is very difficult to answer your question in any other way without an in-person consultation or at least a set of photographs. You should definitely follow up with your treating physician. Good luck from New York City

That doesn't seem right. 
Talk with your injector as soon as possible.
