2& 1/2 Units of Botox Injected into Each Side of Mouth, Now One Side is Drooping, How Long Will It Last?

lauren073
I had Juvederm and 2& 1/2 units of Botox injected into each side of my mouth for smile lines one week ago and as of day number 4 I noticed my mouth and smile are crooked with one side drooping down. Today is looks to be worse than yesterday. I know botox can last 3-6 months but is there any chance it till wear off sooner based off of it only being 2& 1/2 units? Or does it negate that because I had the units placed directly into that muscle? Lastly could a small amount of filler help?
