The original prescriber I haven’t seen in many years. My family doc has been doing refills for the last few years. My previous doc retired. He said when I wanted to drop down dosage to 100 sr to let him know. That seemed like a big first drop. But that’s the next lowest dosage. When I when off lexapro I did about a 10% drop for a month at a time because of the withdrawal effects I was experiencing. I did that by cutting the pill. My last doc told me to drop a pill a week but that did not work so I continued taking it for another 5+ years. And here I am. Just didn’t know if I can cut an SR or do I need to ask for an IR .
