I made drug cards and studied them when I could. I wrote the classification of the med, nursing implications, pt teaching, side effects and whatever I thought was important and was a must know like must take with food or avoid such and such with this med...sounds like a lot but every drug only took up one note card each. We were also taught that since as you know it is impossible to know every drug then if we knew classifications then it would make it a little bit easier like if I see something that ends with olol I think Beta adrenergic blocker and I know what they do..etc... Also theres this cute little book that will fit in your purse called second edition Mosby's pharmacology Memory Notecards and it has funny pictures and Mnemonics that make learning/memorizing drugs easy and less stressfull. I know it sounds like a lot but i carry the notecards and the little book in my bag all the time and just look at it when im not doing anything or in a long car ride when my husbands driving and its helped me a lot.
