This is a very interesting question. I have heard that mixing these types of drugs are dangerous so many times, yet doctors do it all of the time. Cymbalta and Savella are similar drugs- they are both SNRIs. I think if your doctor is monitoring you well, you should be ok, but if you are uncomfortable with the treatment, it is your body and your responsibility to speak up and say something.
Is your doctor planning on switching you to Savella, or just planning to keep you on both meds ? Because if you are weaning down off of the Cymbalta and beginning the Savella, this might make more sense? To pull you off your Cymbalta abruptly might shock your system.
I have found if you are questioning meds it is better to talk to someone than uses them on a regular basis. Pharmacists only job is medication. This is where I usually begin.
On another note, when I was still working I had a client that was on mega doses of a few psych meds. The pharmacist said it was way too much. I went and spoke with the psychiatrist that did the prescribing. She was wonderful to talk to and she had so much experience with the meds in question. I came away comfortable with the care she was receiving. So if you are concerned, it would be helpful maybe to talk with a psychiatrist that prescribes combinations of all the different antidepressents etc. together everyday.
What is important is that you do question it before you start taking it. I have read about the problem with serotonin syndrome too. All docs are human. The doc may have forgotten or overlooked that you were on Cymbalta. It wouldn't hurt to double check.
On a personal note, Cymbalta did not help me at all. Savella has been working very well for me with pain.
Hope it helps,
I think kmil1999 brought up some really good points. Some pain clinics get so busy with people and prescribing medications that is it possible that they may have overlooked the fact that you were already on Cymbalta before giving you the trial of Savella. Also, psychiatrists really do have the most knowledge and experience when dealing with anti-depressants. That's their baby so to speak.
I would definitely make a phone call to the doctor just to make sure they meant for you to take the two together- just to ease your mind. I know there are safe combinations of these types of medications at low doses, although I am not sure about these two in particular- especially since Savella is so new to US doctors.
I took Cymbalta too and I was taking an NSAID as well. If you have ever seen the commercial on TV, it clearly states bleeding can occur if you take Cymbalta with an NSAID. Well I suffered horrible diarrhea and couldn't continue on with the treatment and I didn't even know about the increased bleeding risk. There is always a normal bleeding risk with NSAIDs- well with Cymbalta and NSAIDs together it increased even more! My doctor must not have realized this interaction. This is why you should always be your own advocate and point these things out when you can. I think you are doing the right thing to question your safety and health.
As far as Savella goes, I have not tried it myself, but I've heard lots of good things, but every body is different.
