For those of you with insurance benefits that cover a 90d supply, but you don't want to send 90 at a time away to school, just ask the pharmacy to send 90 in 3 containers. Explain to them that it is a scheduled drug, and your doctor has recommended that your student only have 30 on campus at a time. If it is a mailorder pharmacy like Express Scripts or Medco, etc, just call or fax or send a written note with the RX. Kids who need a portion of their meds at the clinic at high school ask all the time for their 30 or 90 day scripts to be split into 2-3 bottles so that each one has the appropriate label.
And in this day and age, there are NO doctors who receive payments for writing certain prescriptions, unless they are HMO doctors trying to change you to generics. Payments for prescriptions are not only unethical, they are for the most part now illegal. I sometime change patients from a cheaper generic to an expensive newer long acting med because there are potentially huge benefits, less side effects, and I do it because I know the patient will benefit. And many newer, expensive drugs do have 30d samples available, and websites with coupons to download for use with future purchases. For the kid who hates Adderal, and feels great-- or at least more normal-- on a newer expensive nongeneric med, his/her doc did them a favor. There is really no such thing as a kickback anymore. And 98% of practicing DOCS never were involved in that sort of thing anyway.
