What are LEMS and myasthenia gravis?
LEMS and myasthenia gravis are both progressive neurological disorders that cause muscle weakness. Although the causes are different, many of their symptoms diseases are similar, and it’s not uncommon for people to be misdiagnosed with myasthenia gravis before being diagnosed with LEMS.
LEMS and myasthenia gravis patients should discuss with their primary physician before receiving Botox as treatment.
Here are some frequently asked questions about Botox:
What is Botox?
Botox contains a purified toxin from a bacteria called Clostridium botulinum. This is the bacteria that causes botulism if it infects you.
The purified toxin can be used to paralyze specific muscle groups in the area where it is injected.
In beauty treatments, Botox is used to temporarily smooth wrinkles on the face.
Botox may also be used to treat conditions like excessive sweating or overactive bladder.
How is Botox administered?
Botox is injected into the muscles or nerves to paralyze them. The procedure takes only a few minutes.
How long does a Botox treatment last?
Botox treatments last from three to 12 months, depending on the condition being treated.
Why should LEMS and myasthenia gravis patients avoid Botox?
While in most cases Botox’s toxin remains in the injection site, in some it can leach from the injection site and cause muscle weakness and paralysis elsewhere, the FDA warns. Swallowing and breathing difficulties, for example, are not uncommon in people treated with Botox.
In LEMS and myasthenia gravis patients, who already may have muscle weakness that may affect their breathing, symptoms may be exacerbated by the administration of Botox. In extreme cases, the paralysis caused by Botox can be fatal to these patients.
