The classes of prescription drugs most commonly abused are: opioid pain relievers, such as Vicodin® or Oxycontin®; stimulants for treating Attention Deficit Hyperactivity Disorder (ADHD), such as Adderall®, Concerta®, or Ritalin®; and central nervous system (CNS) depressants for relieving anxiety, such as Valium® or Xanax®.1 The most commonly abused OTC drugs are cough and cold remedies containing dextromethorphan.
People often think that prescription and OTC drugs are safer than illicit drugs. But they can be as addictive and dangerous and put users at risk for other adverse health effects, including overdose—especially when taken along with other drugs or alcohol. Before prescribing drugs, a health care provider considers a patient’s health conditions, current and prior drug use, and other medicines to assess the risks and benefits for a patient.
Prescription and OTC drugs may be abused in one or more of the following ways:
Taken as intended, prescription and OTC drugs safely treat specific mental or physical symptoms. But when taken in different quantities or when such symptoms aren’t present, they may affect the brain in ways very similar to illicit drugs.
For example, stimulants such as Ritalin® achieve their effects by acting on the same neurotransmitter systems as cocaine. Opioid pain relievers such as OxyContin® attach to the same cell receptors targeted by illegal opioids like heroin. Prescription depressants produce sedating or calming effects in the same manner as the club drugs GHB and Rohypnol®. And when taken in very high doses, dextromethorphan acts on the same cell receptors as PCP or ketamine, producing similar out-of-body experiences.
When abused, all of these classes of drugs directly or indirectly cause a pleasurable increase in the amount of dopamine in the brain’s reward pathway. Repeatedly seeking to experience that feeling can lead to addiction.
Opioids can produce drowsiness, cause constipation, and—depending upon the amount taken—depress breathing. The latter effect makes opioids particularly dangerous, especially when they are snorted or injected or combined with other drugs or alcohol.
Stimulants can have strong effects on the cardiovascular system. Taking high doses of a stimulant can dangerously raise body temperature and cause irregular heartbeat or even heart failure or seizures. Also, taking some stimulants in high doses or repeatedly can lead to hostility or feelings of paranoia.
CNS depressants slow down brain activity and can cause sleepiness and loss of coordination. Continued use can lead to physical dependence and withdrawal symptoms if discontinuing use.
Dextromethorphan can cause impaired motor function, numbness, nausea or vomiting, and increased heart rate and blood pressure. On rare occasions, hypoxic brain damage—caused by severe respiratory depression and a lack of oxygen to the brain—has occurred due to the combination of dextromethorphan with decongestants often found in the medication.
All of these drugs have the potential for addiction, and this risk is amplified when they are abused. Also, as with other drugs, abuse of prescription and OTC drugs can alter a person’s judgment and decision making, leading to dangerous behaviors such as unsafe sex and drugged driving.
