I'm about to start tapering done off Valcyte, but am very worried about withdrawal symptoms. I had to take a few weeks off about 6 months ago and it was terrible. I only did 3 days of 450 and then went cold turkey. My question is, has anyone cut the pulls in half and gone slower, say down to 675? The patient insert says not to cut the pills in half. I'm assuming this is because they don't want to expose others to the drug I've only seen one other thread mention this here with one person's response. Hoping for more from people who have done this. Thanks!
