Comments from related studies:

  • From this study (1 year ago):

  • My 8yo son started Mesalamine three weeks ago. Two weeks ago he started having regular episodes that look sort of like seizures, and are accompanied by hallucinations. This is potentially ruining our lives. Does anyone know of a connection so I can get the docs to get off their butts and deal with this??


  • From this study (2 years ago):

  • I have been an gabapentin for ten days. 300 mg the first week and 600 mg the last three days. I absolutely hate it! I have had increasing nightmares or sometimes they are total fantasy type dreams. I watched about two minutes of the queen's jubilee floatilla and the next thing I know, Im haaving vivid dreams about me being on the boat with her, waving at the subjects. I am taking this medication for nerve damage and havent felt any pain relief but have been a shell of my self, impossible to be around. I have had slurred speach and confusion and found it difficult to formulate sensible sentences, which I have never had a problem with. Just like a restaraunt that serves anything from pizza, to steak, to everything under the sun. This drug is the exact same. anti-convulsant, epilepsy, social anxiety, neuropathic pain. It is nothing more than snake oil and I am offended that my doctor is prescribing a drug that basically changed the chemical make-up of my brain, with absolutely no positive effects, most likely because Pfizer is giving her a kickback. If it sounds too good to be true, it normally is. There would be no need for any other drug on the market if this so called wonder drug actually did the things that the manufacturer claims. They have hundred's of thousand's of lawsuits pending and I totally understand why. I not a lab rat and I will never take this farse of a medication again. It is my opinion that it is very dangerous and should be much more controlled instead of finding more and more reasons to prescribe it to patients because Pfizer is pushing it to the doctors and pharmacies.


    MrGCat on Jun, 25, 2012:

    Your points are all well taken and well received. My doctor prescribed this poison for me also. When I told him about the side effects he became irate in an accusatory manner, suggesting that I was imagining the side effects. Because of this drug, I have lost respect in my primary care provider and debating whether or not I should continue on with him. You are absolutely correct, the drug alters the brain and creates a mask of the real problem.
