ok so i'm too lazy to read everything this morning, so i stopped at having difficulty with pharmacology..rest assured you aren't the only one.
what i did as far as memorizing drugs/classifications/ contraindications/indications/doseage/peds dose, etc. was get index cards and write the it out like this
Drug Name
classification
indications
contraindications
doseage
ped. doseage
side effects
yea it's a lot to write, especially with the bajillion drugs they seem to throw in your face, but it's worth it.
