Reviews

We picked up some people's comments about the drug Dexamethasone:

  1. Catherine. I have arthritis of the shoulder joint. The doctor prescribed this medicine - she promised that it would cure. Has made 3 nyxes, in 2 months the pain has returned, even more strongly. The weight gain was 15 kg for 8 months. Diet, fitness, exercise machines only slow down weight gain. Because of this medicine, I turned from a slender woman into a quail. The endocrinologist said that I can only accept myself as I am. Former harmony will not return. Never take this medication.
  2. Ulyana. For a long time I can not get pregnant due to problems with the ovaries. Constantly I am flied, this time the doctor has appointed or nominated to me a hormonal agent Dexamethazonum. You should drink 1/2 tablet before bedtime for a month. After a week of treatment, appetite was gone, nausea appeared, but I quickly gained weight. For all the time of therapy I added 5 kilograms. But all this is not so essential, the main thing is that the drug helps me solve the main problem. I hope for a positive result.
  3. Victoria. The drug was taken from the middle of May to the end of September. But since it is a hormonal drug, and taking one tablet a day is considered a small dosage, it began to gain weight. And only parts of the body grew (belly and neck). As a result, the husband scored 10 kg. In addition, taking the drug increases the feeling of hunger. From tablets had to be abandoned. Thanks to sports and proper nutrition, weight returned to normal, and the problem with allergies was solved thanks to the Avamis spray, which is less harmful to the body.
  4. Alexey. My wife was stabbed with Dexamethasone for 35 weeks. The indication was an increase in the antibody titer. They made only 3 injections with an interval of 6 hours. My wife gave birth in time to a healthy son, so I do not see anything wrong with this drug, if it is applied correctly (in a hospital or under the supervision of a doctor).
