How long will the side effects from Botox take to disappear ?

Unfortunately, the only treatment at this point is time.  As you mentioned, it will likely take 3-4 months.  I was unsure from your question if you do still have eye-LID droop.  If you do, this can be treated with Apraclonidine eye drops that may raise your eyelid up to 2mm. Be sure your prescribing physician discusses all the potential side-effects of the drops, such as "adrenaline-like" symptoms like anxiety or heart pounding; you may also experience eye irritation, eye dryness, and eye pain, amongst other symptoms. If these symptoms occur, you will likely need to take some lubricating eye drops, lower the dose, switch the eye-drops, or stop the drops altogether...Again, the good news is that this is not likely to be permanent. It WILL get better.I would encourage you to seek the services of an experienced physician injector. I think the key lies in truly understanding the anatomy of the injected area, and more importantly the variability in the anatomy between patients -- for brows, the forehead, and anywhere else you plan on receiving a Botox injection. This includes having a firm understanding of the origin, insertion, and action of each muscle that will be injected, the thickness of each muscle targeted, and the patient variability therein. As an aesthetic-trained plastic surgeon, I am intrinsically biased since I operate in the area for browlifts and facelifts, and have a unique perspective to the muscle anatomy since I commonly dissect under the skin and see the actual muscles themselves. For me, this helps guide where to inject and where not to. However, with that said, I know many Dermatologists who know the anatomy well despite not operating in that area, and get great results.Good luck.

I’m sorry to hear that
happened to you. For your eyelid droop,
there is a prescription eye drop (Iopidine 0.5%) that you can get from a
physician to help alleviate the droop within a few weeks to a month. The
eyebrow droop will have to resolve on its own within the next few months, as
there is unfortunately no treatment for this. You are correct, that moving your
muscles more frequently may help to make the Botox wear off faster; however, it
may take 3-4 months for all the symptoms to go away.

Dear Sue80,Unfortunately the results you are describing can happen in rare cases.  Usually the fist two weeks is when you feel the most intense effects of Botox.  After that it does tend to get better by itself.  You can also talk to your doctor about an eye drop called iodipine that can help reduce the heaviness and droopiness of the  eyelids.  If this was your first time receiving Botox injections, it is possible that the dose was too strong for you and next time you should start with a lower dose.  There is no proof that exercising your eyebrows will make the Botox disappear quicker--but it can't hurt.  Best of luck.
