A rash from poison ivy, poison oak or poison sumac is caused by an oil found in these plants called urushiol (you-ROO-shee-all). When this oil touches your skin, it often causes an itchy, blistering rash. Most people can safely treat the rash at home.
Most Pharmacy Technician training courses run from about six months to a year, depending on the course. In that time, you will learn the skills required to operate a pharmacy, follow correct pharmaceutical procedures, provide the correct drug dosages, and assist the pharmacist in administrative tasks.
That is the point of going to school even though you're not certified after you graduate. After that, you are then required to become nationally certified within a time period. Back in the days, like in 2000, however, you didn't need to complete a pharmacy program to become a pharmacy tech. You can just walk into a pharmacy and apply.
