Main point, it is prescribed by a medical doctor, I would then assume it is reasonable.
I think the dose level you are taking, 25mg or less, is so low that there is not "shock" to you body by stopping, or starting suddenly.
If you were on 50mg or more per day for
a period of time (how long, I don't know but suggest more than a month) it may be necessary to cut back by half until you are at 25 mg for
a few days befor
e stopping completely.
