Basic Patient Information: Female, Age 34, with significant childhood traumas. Condition: Severe depression and PTSD.
1999: Patient presented with depression and was treated with 50 mg of Zoloft. Within a short time, patient began having paradoxical reaction, and stopped taking the medication.
2006: Patient began taking antidepressants again.
2007: Patient began seeing a psychiatrist to try to find the right combination of antidepressants for her treatment.
- October 11, 2007: Patient was on 112.5 mg of Effexor XR. Doctor wanted to rule out possible bi-polar diagnosis and prescribed lowest dosage of Lithium.
- November 1, 2007: Patient became significantly depressed (also in correspondence with ovulation). No mood improvement.
- November 8, 2007: Patient expressed suicidal ideation, but no plan.
- November 13, 2007: Patient was going to attempt suicide, but stopped the intended actions and contacted a counselor as well as the prescribing doctor for help and treatment.
2008: Patient remains on Effexor XR, no Lithium, and no additional suicidality noted or reported.
QUESTIONS: Is it possible that the patient was experiencing another paradoxical reaction, similar to the 1999 occurrence, with the new combination of the Lithium and Effexor XR? What additional medical documentation is available as proof to validate this concern, for keeping in the patient's medical record?

I am not particularly experienced with these medicines so I cannot be definitive but I'll tell you what I do know. Lithium and Effexor XR can combine to increase the risk of serotonin syndrome. This would not generally appear like a paradoxical reaction.
Effexor XR, by itself, is known to increase the risk of suicidality in some. It may be that this effect is what was being seen. The lithium may have been an innocent bystander in the whole event.

It appears that serotonin syndrome could not be a possible cause of the suicidality due to the fact that the patient has remained on the Effexor XR - lithium was the only medication that was discontinued. The Effexor XR has been augmented with the Levothyroxin for treatment resistant depression (which was the intent of the prescribed Lithium).
If additional suggestions on possible reactions related to the combination of the two medications are available, I would be interested in hearing the ideas.

I've never heard of the addition of lithium to any antidepressant causing suicidality. There is a lot of evidence about the efficacy of lithium, in small doses such as 300 mg daily, for augmentation of antidepressant therapy. I have had a few patients who were unable to tolerate lithium, but these were adverse effects, not suicidal ideation, and didn't seem to be due to a drug-drug interaction.
Results of the STAR-D study were published a few years ago about various treatments for depression, including augmentation strategies. Lithium was added on in that study and found to be effective.

I have been diagnosed with bipolar disorder and also suffer from social anxiety and depression....what is a good medication that has proven safe to accompany the lithium for the social anxiety and depression?
