Brenda,
When wanting to know about drug interactions your pharmasist (msp) is the best person to ask. They are more familiar whith the meds and hear more about their interactions. Doctors don't have the time or want to to keep up with all of this. When taking a new med, I always ask my pharamist if it or and over the counter med will have bad interactions with what I am taking. We do mail order, but the pharmacist we used to trade with always helps me. Beside, I just call and do not give a name, just the meds. LOL

Someone said paxil was hard to get off. I have heard that, but they say I will have to stay on it for yrs. It couldn't be any harder than effexor to get off of and I am taking 20mg of paxil and was taking 75mg of effexor. I have had much worse being overdosed on seizure meds and halucinating so bad; I will deal if it happens.

Panic attacks also can be caused by allergies. I cannot go through the laundry isle in a grocery store, because of all the smells and I guess stuff in the air. I get panic attacks, and panic and anxiety attacks are real. They are triggered in a certain part of your brain, I can't remember now, by many different things. Like I said, until I got off effexor, I had never had a panic or anxiety attack. I had no idea what was happening to me at first. TG my neurologist did.

I think they can happen for a multiple of reason and unknown reasons, we are all different, by what my neurologist and family practitioner say.
Like migraines, fibromyalgia, chronic fatigue, etc. They really do not know the cause for of these yet! Mostly speculations and theories.
