carbidopa/levodopa

[sage43]

I'm trying to eliminate carbidopa/levodopa for RLS. It has augmented to the point that I need it every 3 hrs. around the clock. Neurologist will never prescribe low dose opioid. I am substituting 50 mg pregablin for one of those doses every other time. What is the maximum dose recommended for pregablin?

Substituting pregabalin for one of those doses every other time is not a good idea. It will only make it worse.

Go back up to the last dose that wasn't too bad. Then reduce by a 10-100 tablet every 2 weeks or so. You will have increased symptoms. You may need to reduce more slowly or with a smaller amount. You can cut the tablets in half or fourths. Wait until the increased symptoms from each reduction has settled before going to the next one. You will suffer and may need a low dose opioid temporarily to help out with the symptoms especially as you near the end. But in the long run, you will be glad you came off it. Dopamine agonists like carbidopa/levodopa are no longer the first line treatment for RLS. Gabapentin or pregabalin is. (Pregabalin is more expensive than gabapentin in the US.) The beginning dose is usually 300 mg gabapentin (75 mg pregabalin). Start it 3 weeks before you are off carbidopa/levodopa although it won't be fully effective until you are off carbidopa/levodopa for several weeks. If you want you can start it now. After that increase it by 100 mg (25 mg pregabalin) every couple of days until you find the dose that works for you. Take it 1-2 hours before bedtime. If you need more than 600 mg take the extra 4 hours before bedtime as it is not as well absorbed above 600 mg. If you need more than 1200 mg, take the extra 6 hours before bedtime. (You don't need to split the doses with pregabalin) Most of the side effects of gabapentin or pregabalin will disappear after a few weeks and the few that don't will usually lessen. Those that remain are usually worth it for the elimination of the RLS symptoms. If you take magnesium take it at least 3 hours before or after taking gabapentin (it is OK with pregabalin) as it will interfere with the absorption of gabapentin and if you take calcium don't take it within 2 hours for the same reason (not sure about pregabalin). According to the Mayo Clinic Updated Algorithm on RLS: "Most RLS patients require 1200 to 1800 mg of gabapentin (200 to 300 mg pregabalin) daily."

Have you had your ferritin checked? Improving your ferritin to 100 or more helps 60% of people with RLS and in some cases completely eliminates their symptoms.If not ask your doctor for a full iron panel. Stop taking any iron supplements 48 hours before the test and fast after midnight. Have your test in the morning. When you get the results, ask for your ferritin and transferrin saturation (TSAT) numbers. If your ferritin is less than 100 or your transferrin saturation is less than 20 ask for an iron infusion to quickly bring it up as this will help your withdrawal. Check out the Mayo Clinic Updated Algorithm on RLS which will tell you everything you want to know including about its treatment and refer your doctor to it if needed as many doctors do not know much about RLS or are not uptodate on it as yours obviously isn't or s/he would never have prescribed a dopamine agonist at Https://mayoclinicproceedings.org/a...

If your neurologist won't prescribe an opioid print out that section from the Mayo Clinic Algorithm to show him/her. If he still won't prescribe an opioid you may need to change doctors. If you let me know where you live in the US I may be able to recommend a doctor who will.

Meanwhile some things that can make RLS symptoms worse for some people are alcohol, nicotine, caffeine, sugar, carbs, foods high in sodium, foods that cause inflammation, ice cream, estrogen, dehydration, MSG, collagen supplements, electrolyte imbalance, melatonin, stress and vigorous exercise. Some things that help some people include caffeine, moderate exercise, weighted blankets, compression socks, elastic bandages, masturbation, magnesium glycinate, low oxalate diet, selenium, 5 minute shower alternating 20 seconds cold water with 10 seconds hot water finishing with hot water for another couple of minutes, hot baths, distractions, applying a topical magnesium lotion or spray, doing a magnesium salts soak, vitamins B1, B3, B6, B12, D3, K2, if deficient, and potassium and copper if deficient, massage including using a massage gun, using a standing desk, listening to music, meditation and yoga.

Many medicines and OTC supplements can make RLS worse. If you are taking any and you list them here, I can tell you if any make RLS symptoms worse and if so may be able to give you a safe substitute.
