Q: i take isosorbide mononitrate er (imdur) 60 mg daily. will i become tolerant to this?! i take it every morning at the same time. 10-11 am?

: To avoid tolerance to the medication you have to have about a 12 hour period each day of no medication. With taking every day early in the morning at the same time this allows a drug free time in the day. So you are doing the right thing.
