What's wrong with Luvox?

Monday, September 25th, 2006

Question:  Why are you so down on Luvox?  It has worked well for me in the past.  Also, I use 1200 of Lithium and my creatinine is 1.2.  I have used it 10 years.  At what creatinine level should Lithium be stopped?  I would try Abilify but am diabetic. - John

Answer:  I wouldn’t say I’m “down” on Luvox.  I do have a few patients who seem to do well on it.  The reason I try other serotonin reuptake inhibitors is that Luvox has the most drug-drug interactions in that group of meds (Prozac, Zoloft, Paxil, Celexa, Lexapro, low dose Effexor XR 37.5-75).  For example, Luvox blocks the metabolism of caffeine – which may be the reason it causes more insomnia.  It can cause more daytime sedation. It also blocks the metabolism of all the meds (and hormones) in the 3A4 category (the biggest group), so that can make things very complicated.

Prolonged use of Lithium can lead to some type of kidney impairment, probably inflammatory.  It’s more likely if serum levels are higher (1.0 and above) and may be more likely in individuals that have frequent urination and thirst.  It usually develops after years of use, and so far in my experience, it has not progressed to be a severe problem. But usually the Lithium itself was stopped.

I don’t routinely monitor creatinine levels.  They only start going up if kidney function is reduced by 75% or more.  If that occurs, the serum Lithium will go up without a change in dose or decrease in sodium intake or excess sodium loss (e.g. taking diuretics, vomiting, or diarrhea).

The normal creatinine range is 0.7 to 1.3.  One high value could be some minor issue, so it needs to be repeated.  Other tests are more specific (e.g. 24 urine creatinine or creatinine clearance).  One easy test is to restrict water and see if you can concentrate your urine (becomes dark).  Urine can also be tested with a dipstick available over-the-counter for specific gravity (level of concentration), glucose, protein, inflammatory cells, etc.

The fact that you have Diabetes is a bigger concern as regards your kidneys.  I’m sure your doctor has counseled you about the importance of maintaining good blood sugar levels.  There shouldn’t be any sugar in your urine.

I don’t think you should rule out Abilify because you have Diabetes.  The FDA has required all meds in the atypical group (Abilify, Geodon, Risperdal, Seroquel, Zyprexa, and Symbyax) to list Diabetes as a possible side effect. But actual reported cases with Abilify have been extremely rare.

As with all meds, the decision comes down to benefit vs. risks, and in your case, Abilify might be a good option.

How Does Deep Tissue Stimulation Help OCD?

Tuesday, September 19th, 2006

Question: I recently saw a special on deep tissue stimulation for OCD. It worked in this patient. How does deep tissue stimulation work? – Lea

Answer: I have not seen anything about that.  However, I recommend the Brain Lock technique to all my OCD patients – preferably to listen to the audio tape version of the book.
In the book Dr. Schwartz describes a cognitive behavioral technique used in a successful study done at UCLA.  The most important step in the technique is to shift your focus to something else.  At any given moment your focus is in your mind, in the environment, or in your body.  When stuck in obsessive thoughts or compulsive rituals, you need to shift focus.

  • In your mind: thinking about something else or visualizing.
  • To the environment: listening to music, watching a movie, playing a video game
  • Into your body: exercising, yoga, etc. 

Deep tissue stimulation at the least would help shift focus to the body.  If combined with breathing or other relaxation techniques, it could also facilitate a shift into a more relaxed state of brain activity (alpha rhythm – slower and bigger waves than the usual beta activity of the awake state).  In the alpha state, the mind is more creative and not distressed which facilitates more positive thinking and imaging.  The same state can be achieved through long aerobic activity like running or meditation.

So, I can see where deep tissue stimulation could be useful for anyone with stress overload symptoms.  The problem that I would expect to see is that it works that day and the benefit lasts for awhile, but next week or next month, significant symptoms may return and deep tissue stimulation may not be available or feasible.
