Dr. Jung, who had done additional tests on more patients, concluded in a Dec. 1955 report that “K 17 doesn’t show any undesirable side effects if dosed correctly”. By then he had tested the substance on over 100 patients. Most of those patients were suffering from tuberculosis. In his report, Jung talked about dizziness, constipation and shaking limbs in connection with Thalidomide, but concluded that those side effects only appeared if the dosage was too high.
