Prescription writing

  1. 1. Prescription Writing Date: Name of the patient: Age: Address: RX ............................. Sig
  2. 2. *The importance of the prescription and the need for complete understanding and accuracy made it imperative that a universal and standard language be employed. Thus, Latin was adopted. *Abbreviations Rx - recipe - take thou Sig - Signature o.d. - omni die - daily o.m. - omni mane - every morning o.n. - omni nocte - every night b.i.d. - bis in die - twice a day t.i.d. - ter in die - three times a day q.i.d. - quater in die - four times a day s.o.s. - si opus sit - if necessary a.c. - ante cibos - before meals p.c. - post cibos - after meals p.o. - per os - by mouth E.g. 1 cap t.i.d. pc - take one capsule three times daily after meals *The directions to the pharmacist, usually consisting of a short sentence such as: "make a solution," "mix and place into 10 capsules," or "dispense 10 tablets." *The instruction, "take as directed," is not satisfactory and should be avoided. The directions to the patient should include a reminder of the intended purpose of the medication by including such phrases as "for pain," "for relief of headache," or "to relieve itching" *The physician should designate the number of refills he wishes the patient to have. *In recent years, some hospitals and private physicians are indicating on the prescription their willingness or desire that the pharmacist dispense a non-proprietary or "generic-named" preparation instead of the trade name item written on the prescription. Some have a box on the prescription designated "N.P.P." In this way, the pharmacist can use a form of the drug which may be less expensive to the patient. Legend Drugs: These drugs may not be dispensed by a pharmacist without a prescription from a physician, osteopath, dentist, etc. Federal and State drugs are "legend." Labels on these medications carries the legend: "Caution! Federal law prohibits dispensing without a prescription." *Controlled Drugs: In addition to requiring a prescription, these drugs require additional safeguards for storage. Refills are also limited. Both State and Federal government agencies promulgate regulations regarding these drugs. The Federal agency is the Drug Enforcement

The physician is respon-sible for having all the pertinent in- formation on the prescription. *Controlled Substance Prescriptions ● C-I Examples -- Heroin, Marihuana, LSD ● C-II Examples -- Morphine, Methadone, Meperidine (Demerolâ), Codeine, Oxycodone, Mehthylphenidate (Ritalinâ) ● C-III Examples -- Chlorphentermine, Paregoric, Nalorphine ● C-IV Examples -- Choral hydrate, Phenteramine (Fastinâ), Diazepam (Valiumâ), Lorazepam (Ativanâ), Phenobarbital, Clonazepam (Klonopinâ) ● C-V Examples -- Cough syrus with codeine, buprenorphine *Prescription Drugs ● Regular - non-addictive ● Controlled substances - substances which may produce physical or psychological dependence; special rules and regulations apply; controlled by both State and Federal laws; established by law into "Schedules" in decreasing order of abuse potential ○ Schedule I ■Substances with no accepted medical use in the US ■Examples: heroin, LSD, peyote, mescaline, psilocybin, THC, etc. ○ Schedule II ■Substances that have a high abuse potential with severe psychic or physical dependence liability ■This list consists of certain narcotic, stimulant, and depressant drugs
