Panic Attacks?

[lucky7wedding]

Hi, I have been a phentermine 30 dose user for approx. 11 years, on and off. I have always gotten great results, and had few side effects (other than the dry mouth, sleeplessness, etc).

About 3 months ago, I tried the phen pro combination b/c I seemed to have developed a 'tolerance' for the regular phentermine 30. The phen in the phen pro combination is 37.5.

I took this combo with no side effects for 2 months. Then one day I had a panic attack. I had no idea what was happening to me, and I was terrified. I truly thought I was going to die. That happened on a Monday. Tuesday, I took nothing, and I was fine. Wednesday I took one of my regular phen 30's, without the pro. Almost instantly when I swallowed the pill, I felt the onset of another panic attack.

I went to the doctor, sure I was dying. They diagnosed a panic attack & gave me a xanax prescription & told me to get some sleep. (I have never even filled that prescription; I don't think I have anxiety problems, and am fortunate to say that my life currently has less stress than ever before).

I have been terrified to take any medication since this happened to me. However, I have gained six pounds in the past 4 weeks, in spite of increased exercise & attention to my diet. I am very discouraged and really need to start taking the medication again if I can, but do not want to jeopardize my health/life/OR have another one of these horrible panic attacks.

Any suggestions, comments, or other experiences would be really helpful.

Are you taking any kind of anti depressant? My pharmacist told me that while rare, if you're taking an anti depressant, something called "seratonin syndrome' can occur while take phen. He said if it happens it will feel like a panic attack. It can be fatal. If you are takiing an anti depressant you should google the term and educate yourself on it so you know what to watch for. Good luck!

The phen pro combination uses 'fluoxetine' as the 'pro' (short for prozac, the fluoxetine is the generic name). Funny, I read all about serotonin syndrome when I was having the panic attack feeling, and I had all of the symptoms. I never, never had a problem with my phentermine 30's in the past, but it seems like this mixture may have caused the panic attack. I think the serotonin syndrome may have been what happened to me. It is scarier than anything I could ever imagine. I had a cool burning sensation that went through my body in 'waves', in addition to profuse sweating, dilated pupils, extreme thirst, body shakes, rapid heart beat, dizziness.

I think the fluoxetine stays in your body system for awhile, but not sure how long. I am going to try the phen 30's again when I think its been flushed from my system.
