I was taking 50mg of Seroquel and 50 mg of Zoloft BID and was striken with Seratonin Syndrome and had a stroke on 11/2/09. The first 48 hours the doctors did not think I would survive. Fortunately the MD on duty in the ER had seen this once before and knew what to do. After getting me stabilized, I has massive seizures for 4 days. It is now 6 weeks later anf I am alive and healthy. Unfortunately I am still dealing with the effects of the stroke with left side weakness. I expect to make a full recovery in 4-6 months (God willing). I say to anyone taking anti-depressants - "Watch yourself and make sure your doctor is aware of any changes in behavior or symptoms however small" My dosages were small and a small increase to the dose almost killed me.
Not to doubt your doctors diagnosis of Serotonin Syndrome, but I just can't see how a low 100Mgs of Zoloft and Seroquel would cause Serotonin Syndrome.
Is it possible that you just had somekind of allergic or bad reaction to the Seroquel?
Go immediately back to your doctor or the ER. You should not be having this, and don't leave until you have answers. It sounds to me like you had a reaction to the drugs. If you are bi-polar and depressed you need meds, but maybe not the ones they put you on. Never stop this type of medication abruptly, as it can cause seizures among other things. It sounds as if your fear of this happening again is adding fuel to the fire, but you still need to find out for sure what is going on. My son's hands locked in a clenched position the night before he was to have his colon removed (at age 12). The docs said it was fear. I took him to the playroom where we played a game with me, and they relaxed. Don't wait for an attck to take the Ativan, I'm sure they prescribed 1 or 2 or 3 times a day.
