Welcome to the Central Texas Support Group website for those affected by the neuromuscular disease Myasthenia Gravis (MG).  We invite you to read through the site and to attend our support meetings as both are available to assist in raising awareness about this condition.  Our group consists of those experiencing MG, family and friends of people with this disease, caregivers, and those simply interested in learning more about Myasthenia Gravis.

Join us! Our support meetings take place on the second Wednesday of each month in Northwest Austin.  We begin at 7 PM (CT) and chat for an hour, sometimes longer.  Thank you to the Austin Public Library - Spicewood Springs Branch (click link for map) for allowing us to use their facility for our meetings.  We'll look forward to having you with us at our next gathering!


Medication Awareness: "Did you know..."

... there are are several medications MG patients should avoid due to their adverse effects. Please check with you doctor before taking any of the medications listed.

D-penicillamine and alpha-interferon should not be used in myasthenic patients as they can cause MG. Botulinum toxin should also be avoided.

Increased weakness in a significant number of MG patients has been reported with the following drugs. Use only with caution and monitor for exacerbation of MG symptoms.

  • Neuromuscular blocking agents such as succinylcholine and vecuronium should only be used by an anesthesiologist familiar with MG
  • Quinine, quinidine or procainamide
  • Selected antibiotics, particularly aminogylcosides, telithromycin (Ketek) and ciprofloxacin (Note: Many other antibiotics have been reported to increase MG weakness in occasional patients.)
  • Beta-blockers (propranolol, timolol maleate eye drops), Ocular DrugsTimolol maleate, proparacaine hydrochloride, tropicamide
  • Calcium channel blockers
  • Iodinated contrast agents (a form of X-ray dye)

The above list is not all inclusive; please consult with your physician or pharmacist. Numerous additional medications are reported to increase weakness in occasional patients with MG. The MG patient and physician should be alert to this possibility whenever a new medication is prescribed.

More thorough, complete and up-to-date information on drug effects in MG may be found at the MGFA web site; reference document “Medications and Myasthenia Gravis: A Reference for Health Care Professionals.”
