Good morning Jake,
My neurologist orders and I go to my local Apheresis/Infusion unit of a hospital once a week to receive 900mg of intraveneous lidocaine. I am hooked up to heart monitors as its important for constant monitoring. Lidocaine infuses by a slow drip over 4 hours and vitals are taken every 15 minutes for first hour then every half hour for the duration. I have been receiving lidocaine infusions for 11 weeks and began at 600mg. Slowly increase over time until you feel you are receiving proper benefit. I'm meeting with neurologist in 2 weeks to discuss my over all plan. I believe he can increase the dose one more time to max it out and that doseage is based on weight and age by formula. Hope this helps!
I do believe it is well worth the try for anyone with chronic neuropathic pain or fibromyalgia. Good luck!
