Title: Serotonin Syndrome Post by hootchdom on Nov 21st, 2003, 4:28am With more of us taking SSRI's, I just wanted to post the following. As always, consult with your doctor and make sure he/she is aware of all meds you are taking. Triptans (Imtrex) are an MAO which taken with other serotonin inhibitors, anti depresants (prozac) can cause a deadly condition known as Serotonin syndrome. "The serotonin syndrome is a hypersotonergic state which is a very dangerous and a potentially fatal side effect of serotonergic enhancing drugs which can have multiple psychiatric and non-psychiatric symptoms. It is a condition which has been on the rise since the 1960's when we began using more and more drugs which directly affect serotonin. This is a toxic condition which requires heightened clinical awareness in order to prevent, recognize, and treat the condition promptly. Promptness is vital because, as we just mentioned, the serotonin syndrome can be fatal and death from this side effect can come very rapidly. This syndrome is a toxic hyperserotonergic state whose rate of incidence is unknown, but is on the rise. The suspected cause of that increase is the introduction of the new selective serotonergic enhancing agents in clinical practice - the SSRIs. This disorder, brought on by excessive levels of serotonin, is difficult to distinguish from the neuroleptic malignant syndrome because the symptoms are so similar. The neuroleptic malignant syndrome is a serious condition brought on by the use of the neuroleptic drugs. "The symptoms of the serotonin syndrome are: euphoria, drowsiness, sustained rapid eye movement, overreaction of the reflexes, rapid muscle contraction and relaxation in the ankle causing abnormal movements of the foot, clumsiness, restlessness, feeling drunk and dizzy, muscle contraction and relaxation in the jaw, sweating, intoxication, muscle twitching, rigidity, high body temperature, mental status changes were frequent (including confusion and hypomania - a "happy drunk" state), shivering, diarrhea, loss of consciousness and death. (The Serotonin Syndrome, AM J PSYCHIATRY, June 1991) "The serotonin syndrome is generally caused by a combination of two or more drugs, one of which is often a selective sertonergic medication. The drugs which we know most frequently contribute to this condition are the combining of MAOIs with Prozac (this should also include the other SSRIs) or other drugs that have a powerful effect upon serotonin, ie, clomipramine (Anafranil), trazadone (Deseryl), etc. The combination of lithium with these selective serotonergic agents has been implicated in enhancing the serotonin syndrome. The tricyclic antidepressants, lithium, MAOIs, SSRIs, ECT (electric shock treatment), tryptophan, and the serotonin agonists (fenfluramine) all enhance serotonin neurotransmission and can contribute to this syndrome. Anything which will raise the level of serotonin can bring on this hyperserotonergic condition. The optimal treatment for the serotonin syndrome is discontinuation of the offending medication or medications, offer supportive measures, and wait for the symptoms to resolve. If the offending medication is discontinued, the condition will often resolve on its own within a 24 hour period. If the medication is not discontinued the condition can progress rapidly to a more serious state and become fatal. It should be apparent that the greater the enhancement of serotonin levels, the greater the chances of producing the serotonin syndrome. Therefore it is recommended that Zoloft, Prozac, Paxil, Luvox, Serzone, etc. not be used concurrently with each other or any other serotonergic drugs and that these serious adverse reactions should be expected with these combinations (Callahan, 1993). (PROZAC: PANACEA OR PANDORA?, p. 88)" |
