A parent was on the phone today and said that the internet says that pentoxifylline is a first generation antipsychotic that has the potential to induce TD, which in turn can cause cognitive impairment. I asked her how many years the patient had been taking pentoxifylline. She said she had been taking it for 6 years. Yan Wenwei, psychiatry department of Taicang Third People’s Hospital, I told her that if pentoxifyllidol would trigger TD, then it has been 6 years and it should have appeared long ago. So far for 6 years, no TD has appeared, and it can never appear again. I have at least a thousand patients on pentafluridol and I have never heard of any of them developing TD. In my telephone consultation cases, I did have five or six patients with TD, and those were all patients who got TD while taking risperidone treatment a long time ago, and one case was triggered by ziprasidone. I asked her again if the patient had any cognitive problems. She said no. I told her that practice makes perfect. After 6 years of taking pentoxifylline and no cognitive problems, there is no possibility of that. Those are all rumors, don’t believe them!
