> SLS, I saw you mention in a previous thread that you knew cases where low dose lithium worked once, but once it was stopped, was not likely to work again.

I am still on it and probably flogging a dead horse, but having difficulty coming off it and if I do come off it, will never get it prescribed again here in UK so desperatedly trying to augment it. Recently added 150 mg lithium which magically made it work again, but it only lasted 2 months. And raising the lithium made no difference.

Dammit.
Are you saying that you were fine up until the point when you reduced the dosage of Parnate and then failed to improve again once you returned the dosage back to the previous amount? From what I have observed, that's unusual for Parnate when compared to Nardil. The term used for achieving the same degree of improvement of depression is "recapture". So, you were unable to recapture the same degree of improvement after you returned to the dosage that made you well previously?
The first thing you might ask about with your doctor is the immediate, but temporary, use of an antipsychotic known to have antidepressant properties. Olanzapine (Zyprexa) is probably the most effective anti-suicide AP to address your current mental state. It should work within 24-48 hours at the right dosage. Maybe 10-15 mg/day? Although olanzapine is the AP with the greatest liability for weight-gain (aside from clozapine (Clozaril), you would be on it for a short while - maybe a week or two - while you experiment with lithium or some other adjunct to Parnate. There are a few other APs that have antidepressant properties, but olanzapine is known for its anti-suicide properties.

In the early 1980s, before the emergence of SSRIs, research psychiatric institutions like Columbia Presbyterian / New York Psychiatric would add lithium to tranylcypromine (Parnate) as their go-to augmentor for their treatment-resistant patients. They did the same thing for people who failed to respond to tricyclic monotherapy. Your best option given your circumstances is to add lithium. If you do not have bipolar disorder or schizoaffective disorder, bipolar type, I recommend starting at 150 mg/day or 300 mg/day. Low-dosage lithium has been studied since 2001 when Harvard compared different dosages of lithium when added to two dosages of fluoxetine (Prozac) - 20 mg/day and 60 mg/day. They found that 600 mg/day of lithium worked less frequently than lower dosages. They reported 450 mg/day as being the ideal dosage. Right now, if I go higher than 150-300 mg/day, I actually relapsse. It turns out that lithium has a bimodal dosage-response curve for unipolar depression. Low dosages affects glutamate neuronal function opposite to high dosages. Low dosages are better for unipolar depression while high dosages are necessary to treat and prevent mania.
I am currently taking:
Nardil - 90 mg/day
Nortriptyline - 100 mg/day
Lamotrigine - 300 mg/day
Lithium - 150 mg/dayI decreaseed my dosage of lithium from 300 mg/day to 150 mg/day just last week. I feel significantly better. Two weeks ago, I got hit with a torturous episode of spinal stenosis. I was prescribed meloxicam (perhaps the most potent NSAID) by my orthopedic surgeon. When I went to pick up the prescription, the pharmacist informed me that meloxicam raised the blood levels of lithium. That's what motivated to reduce my lithium dosage.
If the addition of lithium works for you, don't ever stop taking it. There is a good chance that you will never respond to it again if you do. This happened to a friend of mine while we were both research patients at the NIMH institute, a division of the National Institutes of Health (NIH). She remained in full remission the entire eight years she was taking lithium monotherapy. When she moved from NC to CA, her new doctor thought that she had been on lithium long enough, and had her discontinue it. She relapsed withing three months. After her doctor had her restarted lithium, it never worked again That was 25 year ago. Dr. Robert M. Post, the director of the department of biological psychiatry, had her as a patient in 1992. It was shortly after this that he wrote a paper called, "Lithium-discontinuation-induced refractoriness: preliminary observations" in 1992.
