The Tuesday after Labor Day is typically one of Reich’s Pharmacy’s busiest and most stressful days of the year.

The day was busy, but it wasn’t stressful, owner Harold Reich said. That’s because the pharmacy boasts Tracy’s only Script Pro 200, aka Big Bertha, a robot that fills prescriptions faster than the pharmacist can type in the customer’s insurance information.

“It’s so quick, they can barely get the prescriptions in quick enough,” Reich said. “It keeps us caught up all day.”

Normally, two pharmacy technicians can fill 200 prescriptions in a day, Reich said. Since the Script Pro 200 was installed three weeks ago, the pharmacy has been able to fill 450 a day.

The robot, known as Big Bertha to Reich’s team of pharmacists and technicians, is loaded with 183 different prescriptions. A technician enters the prescription, and Big Bertha chooses a bottle size, fills it with pills and sticks the label on the bottle.

The $180,000 robot is also used at two pharmacies in Stockton and about 300 throughout Northern California.
