Flu-like symptoms following Botulinum Toxin (Dysport or Botox)

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Flu like symptoms following Botulinum Toxin (Dysport or Botox) are reported as they are with almost any medication listed in the PDR. However, it should not last 4 months as the vast majority should have dissipated at this point in time. See your physician to search for another possible cause.

Prolonged fatigue and nausea after Botox

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Systemic symptoms (nausea, malaise, muscles aches and headache) occur uncommonly after botox or dysport and generally are gone after several hours to several days. Any symptoms that persist longer than this should be reported to your injection physician and to the manufacturer (Allergan for Botox and Medicis for Dysport). Persistent symptoms may be from other, more serious underlying diseases and patients with post botox injection symptoms lasting more than a few hours should be investigated by an internist, rhuematologist or neurologist (some one knowledegable on the botox side effects).

Dysport effects

Dysport like Botox usually wears off within 3-4 months. If you have fatigue and nausea it is most likely from another source. You probably should go see your internist.

Dysport or botox is not the cause of your nausea and fatigue. See your GP for a workup.

Your GP doc can do a physical and labs to see why you are nauseated and fatigued but it is unlikely to have anything to do with the dysport or botox you got 4 months ago.

Side effects of Botox

If your side effects have lingered this long, it is unlikely to be due to Botox. Regardless, you should have your symptoms of fatigue and nausea evaluated by your primary care doctor for all causes.
