What to Do About Eyelid Swelling After Botox?

You must contact your physician who performed this treatment. They know how many units they used and the places they were inserted. Cold compresses should not affect the good Botox result adversely but again, have your physician see you in person to examine your condition.

In my experience, it seems that many paitents who have botox injected for the first time, experience eyelid swelling that generally resolves by two weeks.
In general, methods of achieving less swelling include ice compresses, elevation of the head at night while sleeping, etc.
In rare instances, anti-inflammatory agents may be prescribed orally or via eye drops. However, these are typically prescribed by a physician,
In any case, discuss your concerns and condition with your physician who is best equipped to diagnose and treat your problem

Botox injections should not cause eyelid swelling, and certainly not lasting for 8 days. You should go back to that doctor, or to your ophthalmologist for follow up. You may have an infection or an altogether unrelated problem. You may need steroids, antibiotics, or further workup.
