Thank you for your question. I would recommend reporting your symptoms to your injector so they can report it to the Botox medical department. You can take some antihistamine such as Claritin or Zyrtec in the morning and Benadryl at night to help with the swelling. It is moving downward due to gravity pull. It may take few days for the swelling to go away. I hope this helps.

People with milk allergy (lactose) should not receive Dysport brand of botulinum toxin. Outside of the botulinum toxin, you may also be allergic to the anesthetic that was used. The dependent ("migrating") swelling in the forehead should ultimately resolve, although it may take some time. Ice packs and sleeping in a recliner may help.

Allergic reaction to Botox?

It is possible that you are allergic to something that was injected which could have been part of the Botox or the preservative in the saline that might have been used to dissolve it. However, it is also possible that you are allergic to what could have been used to clean or numb you prior. I do not use numbing cream for Botox but some probably do. I would certainly discuss this with your doctor as you might want to know what you are allergic to. I have never seen this before. The reaction/swelling is progressing as expected and will soon resolve.

It sounds like you had a severe allergic reaction to the Botox injections.  It is not uncommon to have significant swelling with allergic reaction but you should stay in contact with your doctor and let them monitor your progress.

The last place I would be is on Real Self with an apparent medical emergency - I'm not sure what your physician recommended when you were initially treated but certainly if this was a true allergic emergency, you'd clearly be wise to return to your physician for a thorough assessment.
