Pentazocine can lead to physical dependence when taken for a long time, and some people may develop an addiction. However, there is a significant difference between true pentazocine addiction and a simple physical dependence on the drug. You should seek help if you believe you or someone else may be showing signs of addiction to pentazocine.

Is Pentazocine Addictive?

Pentazocine lactate (Talwin®) is a prescription opioid medicine approved to treat moderate-to-severe pain. It is also sometimes used before surgery or anesthesia. Like other opioids, the chronic use of pentazocine may cause addiction. Because of this abuse potential, it is a considered a Schedule IV controlled substance.

What Is a Schedule IV Controlled Substance?

Controlled substances are medications that have laws and regulations controlling their use. There are five categories of controlled substances, and medications with abuse potential are placed into one of these five categories (Schedule I through V) based on how likely they are to cause abuse and dependence, as well as whether they have acceptable medical uses.
For example, Schedule I controlled substances are considered to have no well-accepted medical use in the United States, but have a high potential for abuse. Examples of Schedule I substances include heroin and lysergic acid diethylamide (LSD). Schedule II substances still have a high abuse potential, but also have well-accepted medical uses. Examples of Schedule II medications include morphine and pentobarbital (Nembutal®).
Schedule IV controlled substances, such as pentazocine, are medications that have a low potential for abuse compared to Schedule III medications. In turn, Schedule III medications have less abuse potential than those in Schedules I and II.
