Pain Home > Talacen

Talacen is a prescription drug approved to treat mild-to-moderate pain. This combination medicine comes in the form of a tablet and is taken every four hours on an as-needed basis for pain relief. Although most people tolerate it well, side effects are possible and include constipation, nausea, and drowsiness.

What Is Talacen?

Talacen® (acetaminophen and pentazocine) is a prescription medication approved for the relief of mild-to-moderate pain. It contains a combination of pentazocine, an opioid narcotic pain medication, with acetaminophen (Tylenol®), a non-narcotic pain medication.
Because it contains pentazocine, Talacen has the potential for abuse and is considered a controlled substance. This means there are strict laws and regulations controlling its possession and use. Talacen is classified as a Schedule IV controlled substance, which has less abuse potential than Schedule II (i.e., morphine) and III (i.e., hydrocodone/APAP) controlled substances.  
Pentazocine is also available in combination with naloxone (Narcan®) as the brand-name product Talwin® Nx. Talwin Nx comes as a tablet, and is taken by mouth. Pentazocine is also available alone as an injectable medication, Talwin® (pentazocine lactate).
