hi - my father is 78 years old. he was diagnosed with TB, and is taking akt4. he has a tendency to have allergy reactions adversely to a lot of medicines. some of his reactions have been lack of sleep, extreme tiredness, inability to walk by himself, needs help for basic functions. he was not so weak earlier. in the last one week, his condition has worsened - no sleep at all and is having some hallucinations. his daily food intake is much below average and largely on liquids. are all these side effects to be expected ? we are concerned.
