Final answer:
OTC drugs like loratadine (Claritin) do not require supervision of a health care professional, can interact with other drugs, and should be included in the drug history assessment.
Step-by-step explanation:
When obtaining a patient's health history, it is important to include information about over-the-counter (OTC) drugs like loratadine (Claritin). OTC drugs do not require supervision of a health care professional and can be purchased without a prescription. However, they can still interact with other drugs and should be included in the drug history assessment. OTC drugs are generally less effective than prescription drugs, but they do not necessarily cause toxicity.
