75 units of Botox on forehead. Now experiencing muscle spasms. Is the botox wearing off? (Photo)

The dosing for Botox is variable and based on the desired effect, the amount of current animation, and the strength of the muscles. For new patients, however, the exact dosing is often discovered through a trial and error process. See link below. Some rough guidelines are:Forehead: 16 unitsCrowfeet: 8 units per sideGlabella: 18 units75 units is a healthy dose of Botox for the forehead. There should be no movement - let alone spasms. Consultation with a surgeon certified by the American Board of Plastic Surgery would be the next best step.

Botox treats muscles spasms doesn't cause them.  What I see in the pictures is dynamic wrinkles or movement lines meaning the toxin is wearing off.  Although, 75 units in the forehead is a WAY too large of a dose.  Are you sure you didnt have Dysport injected?  I suggest speaking to your physician or finding someone who is more of an expert at toxin injections for you next treatment/evaluation.  Best, Dr. Emer.

It looks like you can see wrinkles when you try to lift your eyebrows ... these are called Dynamic wrinkles.  When you are not trying to raise your eyebrows, you're forehead looks quite smooth.  You do not have any Static wrinkles, that is, wrinkles present at rest.  In general, when we treat forehead wrinkles, we are treating Static wrinkles.  Overall it appears that the Botox is still doing what it should.  Once you see wrinkles at rest, then you will know you need another treatment.

There are a couple of unusual aspects of your experience. First, 75 units of Botox is ALOT to treat the glabella and forehead. If you had Dysport treatment, instead of Botox, then 75 units is reasonable for those two areas. I suspect you were treated with Dysport but I am curious to know. Second, the muscle spasms are unusual. Personally, when I first started using Botox I had one treatment where I developed an annoying tic around my left eye as the Botox wore off. This has never occurred again. If you are not having any other neurological concerns then this should not be an issue. If you're having other symptoms let your injector know and followup with them and your internist. If you live in Denver, there's definitely no reason to need to leave town for Botox. There are many expert physician injectors in town.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

If you truly had 75 units in the upper third of your face, you should have no movement at all.  You should verify the number of units and where placed.Dr. Malouf

The amount of Botox injected into the forehead is almost (almost) unheard of. 75 units is quite excessive and for that reason, spasms should be unlikely unless it is > 3-4 months later. Botox treats spasms and does not cause spasms. 

Was this the first time you received this type of treatment?I have had one patient who experienced forehead spasms like yours shortly after her very first treatment.  It went away and has not returned, despite having subsequent treatments. I wonder if the spasms might be more common after the very first treatment, as some cases have suggested.Other comments on your case:75 units of Botox in this area seems excessive for forehead treatment.  Are you sure it wasn't Dysport (a Botox-like neurotoxin), which is measured in roughly three times the number of units. (75 units of Dysport is roughly equivalent to 25 units of Botox).Receiving Botox treatments in the same area, one week apart is unusual, unless for a small touch-up correction.  25 units is much more than a small touch-up dose.

and was it injected just into the forehead and not the glabella - just about the brows...if the 75 units was injected into just the forehead it seems like a huge amount...if it was dysport, still a lot but not out of line...and typically most people wait at least 2 weeks before adding an additional amount...too many things don't compute, maybe you could fill us in to get a more informed answer to your question

You can see there are some wrinkles starting to come back. It seems like a lot of units for your forehead. I think you got your glabella treated as well.  Even though Botox lasts for about 3 months, it starts to fade at 6 or 8 weeks.
