I said I am depressed for about a week (or a little longer) then feel ok for about 3 days or so. The main symptoms I have are feeling extremely fatiqued, somewhat worthless, with much anhedonia. I said the sertraline helped initially, but seemed to stop working. I said they tried higher doses in the hospital which always left me agitated. I also said I have zero sexual function on it.

I am hesitant to tell him about my concerns because traditionally my relationship with psychiatrists has soured when I start to express knowledge / concernes with specific recomendations.

> That's understandable. To your doctor's credit, he would consider imipramine should your trial with nortriptyline be unsatisfactory. Back in the old days, doctors noticed a trend in that desipramine responders did not respond to nortriptyline and vice versa.

> In your mind, I know that genotoxicity is a concern as is cardiotoxicity. The cardiotoxicity thing only really comes into play if one has a predisposing condition or in overdose. To my knowledge, there is no cumulative damage produced at therapeutic dosages. I wish I could speak to the issue of genotoxicity with certainty. I know about the breast cancer thing in Canada, but that post hoc analysis makes assumptions regarding the drugs used to treat depression that they could not verify. Since depression itself might increase one's chances of getting cancer, presumably because it affects the immune system, I don't think that study is a reliable index of genotoxicity. It is probably a more reliable index of the incidence of depression in cancer patients. Obviously, the risk of genotoxicity, unlike cardiotoxicity, is cumulative. People who have been on TCA the longest would have the greatest risk for contracting cancer. A great many individuals have been taking tricyclics for decades, though. I might be wrong to make such an assumption, but I should think that if the cancer risk was so great, someone would have noticed by now. I know it doesn't always work that way. I imagine there a great many things that have escaped the attention of medicine.

> Obviously, you know what my decisions have been as I have weighed the risks versus benefits of taking a variety of different drugs. For me, the depression is so painful and so incapacitating, I really don't have any better alternatives but to take whatever works, especially when the risks can be quantified, as is the case with cardiotoxicity. As it relates to genotoxicity, I consider the risks involved with taking TCA to be more theoretical than actual.

> I think you have to ask yourself how urgent is the need to improve your condition and what alternatives you have remaining. At age 49, I would drink horse piss if I thought it might help. Don't wait too long. You are very bright and can contribute much to society, including the contributions that you will be able to make into your own bank accounts.

>Scott have you ever tried clomipramine? I have a book on psyschotropic drugs at home and clomipramine seems like it could be a very effective drug.
Its potency and selectivity for Norepinehprine is
3.6.
Its potency and selectivity for serotonin is
18.
So it's about 5 times more potent at blocking serotonin reuptake than norepinephrine.This drug is somewhat weaker than the other tcas on NE reuptake but the most potent at SE reuptake of the tcas. Almost as potent as setraline which is a 29 at SE reuptake.
So you get SE and NE reuptake which has advantages but more SE for those who need serotonin but not as much as the ssris.So this drug is unique in what it offers.
