Stop taking haldol (haloperidol) 5 mg a day after a month an half of taking it and continuing taking akineton 2mg at day can avoid the withdrawal effects of haldol (haloperidol)?

Withdrawal effects?: There aren't withdrawal effects of Haldol (haloperidol) in the usual sense. Sudden discontinuation after long use may cause temporary dyskinesia, unlikely after only 1.5 months. It's a good idea to take Akineton (biperiden) for a few days after stopping haldol, to be sure it's all out of your system. You should discuss all this with your prescribing doctor, of course.

Akathesia: Alathesia can be a b****, that's for sure. Have you tried Cogentin or artane? Sometimes, diffetent ones work better. I will go as high as 2mgs three times/day of Cogentin (benztropine), if needed. Of course, benztropine has side effects too. A little benedryl can help. I don't love inderal- too sedating, but low dose nadalol can be helpful. Check with your dr, no matter what.
