What type of controlled substances must be physically evaluated before prescription?

The requirement for a physical evaluation before prescribing controlled substances stems from the potential for abuse and dependence associated with these drugs. Schedule II substances, which include medications such as opioids (like morphine and oxycodone) and stimulants (like amphetamines), are classified as having a high potential for abuse, leading to severe psychological or physical dependence. Due to this high risk, Texas law mandates that a physical examination is necessary prior to prescribing these substances, ensuring that the prescribing physician has a complete understanding of the patient's medical history and current condition.

This evaluation aims to prevent inappropriate prescribing and misuse, which is particularly crucial given the current opioid epidemic. By ensuring that a physician conducts a thorough physical assessment, the system aims to promote responsible prescribing and safeguard patient health.

In contrast, while other schedules like Schedule III and IV contain substances that may potentially lead to moderate or lower dependence, the legal and medical safeguards concerning their prescription are not as stringent as those for Schedule II drugs. Therefore, they do not require a physical evaluation to the same extent, reflecting the difference in risk associated with these medications.
