When Will Botox Get out of my Body? Muscle Symptoms/Weakness of It Leaving?

I read your posts and hope you are doing better. I expect both BOTOX and Dysport to last from 3-5 months. The symptoms you describe do not sound like they are stemming from your injections. People who react to BOTOX generally manifest thisreaction by experiencing a much shorter period of effective muscle weakening. They are thought to have antibodies to the molecule, thus destroying it sooner. When massive doses of BOTOX or generic botulinum toxin are administered, overall weakness and other problems can be seen. If you haven't already done so, please see a neurologist to get evaluated for other cause of your problems.

Botox effects generally last from 3 to 4 months.  Although generalized muscle weakness and fatigue have been described with Botox injections, those occur more often with large doses of Botox injected for musculoskeletal problems, and extremely rarely with Botox used for cosmetic treatments.

By six months post-injection, Botox effects should be pretty much gone.

The symptoms you are describing are concerning.  I recommend consulting your primary care physician and a neurologist to look for other causes of overall weakness and fatigue.  There are multiple possible causes, starting with certain vitamin deficiencies to neurologic or musculoskeletal disorders.  You need a workup to see if any of these issues are present.
