Hi Honey, I just found this post. It's definitely the changes in the medications that are making you feel awful. I'm so sorry! I go through the same thing all the time, even without changing medicines--and it's extremely miserable.
**I just had the Serotonin Syndrome talk with my Psych last week**
Lexapro is a full serotonin medicine (SSRI), and Savella and Cymbalta are SNRI's -- part serotonin, part norepinephrine. Cymbalta is 50/50 even between the two, Savella is 3:1 norepinephrine, so that brings the serotonin level even lower.
This isn't an uncommon combination of medications, and it's usually necessary when moving from one to another. You need to overlap them to avoid withdrawal symptoms, and as long as you are decreasing one medication while starting the other, it's still basically the same amount of serotonin. Lexapro and eventually Cymbalta is a common combination, their mechanisms are different, and the probability of serotonin toxicity is low.

You just have to follow the doctor's directions--- Like Jillian said, you can't just stop one. Decrease the Savella as he said, but don't just stop it. You will have even worse side effects and withdrawal symptoms. Or stay where you are until you can talk to him.
My doctor said that there are a lot of symptoms of Serotonin Syndrome, but the things he told me to watch for the most, what concerns him the most, are:
- Chattering Teeth
- Severe Muscle Twitches
- Uncontrolled Shivering
- Pounding Heart
Right now, I'm on Effexor, Savella, and Viibryd. I'm decreasing the Effexor to stop it due to horrible side effects for years, and increasing the Savella at the same time. The Viibryd stays the same. He told me I'd basically have to overdose to cause a dangerous level of serotonin toxicity during this change-over.
I haven't done Savella to Cymbalta, but many many other SSRI's and SNRI's--I've been on 3 Serotonin anti-depressants maintenance at once, with a few other goodies mixed in (anti-seizure meds for mood stabilization, benzodiazepines, etc).
I did have one Psych hand me 7 prescriptions at my first visit, and send me on my way with no instructions! (quack) -- Luckily, in all the years I've been on anti-depressant cocktails, I've never had Serotonin Syndrome.
CAN YOU TELL I DRIVE MY PSYCHIATRIST CRAZY WITH QUESTIONS ???
PS: (Cymbalta is known to cause Urinary Retention ....)
Don't worry yourself sick over the weekend---if you feel off, GO TO THE EMERGENCY ROOM, or try to call your doctor, and next week talk to him about your meds !
Hugs,
Renie
