We picked up some of the people's comments about Diakarb:

  1. Christina. Periodically, the eye pain, feeling as if pushing the eye from the inside outwards was disturbing. I tried many medicines, and did not even know what this pain is connected with. Has passed medical examination, MRT and other, have written out the given preparation with a number of others within a month. The course is designed for five years, every six months to drink the drug. The pain immediately went away after a month, besides it relieves the pain of recurrent pain within 20-30 minutes. Pain after the course was not disturbed for a year. A year later, they made a little impression of themselves, again drank a month's course and anxiety went away. In general, an excellent tool, the only one that helped me.
  2. Julia. For more than 10 years I suffer from epilepsy. Once, when visiting a neurologist, he prescribed Diakarb to me. After reading the instructions for use, to say that it was in shock, it's nothing to say. After the first pill, the action begins in about 30 minutes, so you can not get out of the house. Also, it dehydrates the body and displays potassium and it is recommended to take it with an asparagus, the doctor did not warn me about it. At me on the second day there were headaches, delicacy and drowsiness, that too was not pleased. Therefore, after 5 days decided to stop using, because instead of improving some side effects.
  3. Nelya. After the operation to remove the tumor of the brain, diacarb was discharged. Saw on a tablet 3 times a week in pair with asparkamom. I drank before going to bed and in the morning, tingling began in the fingers, a feeling of numbness in my lips, and drowsiness. I was very frightened, but having read the instructions and the side diacarb calmed down, I will take the drug further. Apparently all these symptoms are natural when taking diacarb. Thank you.
