OK so backstory here: The patient was switched to Adderall XR 20mg from Vyvanse.. the doctor seven days in decided to raise the dose to 30mg. Instead of sending over Adderall XR 30mg, she sent over 10mg instead and told him to take both. I told the doctor I wouldn't fill the 10mg script after just filling the 20mg, and told her if she'd like to send over 30mg (since that is the actual dose she wanted him at) I would be able to fill that for the patient. She agreed and sent that over. The patient comes in and told me the doctor told him to use the 20mg capsules and to open the 30mg capsules and split the contents into 3, find empty capsules and use 1/3rd of the contents in the empty capsule to get the 30mg dosage. I was first a bit shocked that was even a suggestion but cautioned the patient not to do that because there's no guarantee he's getting the correct dosage, especially because it's a time released medication. I'm still a bit shocked that a doctor would suggest that to a patient. I'm planning on following up with the prescriber tomorrow but has anyone heard of a physician suggesting that before?
