I noticed some of the pills (though of the same dosage) have sometime an NRP imprint or S489 imprint on the other side of the pill. To me, the ones with S489 are like placebo! Anyone else noticed or sensed this?? I am over-senstive and very alert to how medicine works. Thanks.
Oh my God, yes! My son takes vyvanse 20 mg and has always done well on it. I refilled his prescription 2 days ago and noticed his behavior was different, unfocused and starting to have eye ticks. I checked his medicine to see if the pharmacy made a mistake and saw the S489 on the pill but the label said NRP 104. I believe their is definitely something different about the formulas. Now what am I going to do? The pharmacy says its the right medicine.
