Question

a female patient presents a new prescription for isotretinoin (accutane). in the previous week, the patient had picked up a prescription for prenatal vitamins. which of the following warnings should a pharmacy technician expect to be displayed?

○ contraindication

○ drug allergy

○ drug-to-drug interaction

○ therapeutic duplication

Explanation:

Isotretinoin (Accutane) is highly teratogenic, meaning it can cause severe birth defects. Prenatal vitamins suggest the patient may be pregnant or trying to conceive. A contraindication exists when a drug should not be used in a particular situation (here, pregnancy with isotretinoin). Drug allergy would involve a reaction to the drug itself, drug - to - drug interaction is between two drugs' effects, and therapeutic duplication is repeating the same therapy. Since isotretinoin is contraindicated in pregnancy (suggested by prenatal vitamins), the warning is contraindication.

Answer:

A. Contraindication
