Summary
Pentazocine is used to relieve moderate to severe pain, which is discomfort that can interfere with daily activities. It's often prescribed after surgery or injury to help manage pain effectively.
Pentazocine works by binding to opioid receptors in the brain, which are parts of the brain that control pain signals. This action blocks pain signals, reducing the perception of pain and providing relief.
The usual starting dose for adults is 50 mg every 3 to 4 hours as needed for pain, with a maximum of 600 mg per day. It's taken orally, which means by mouth, and should be used exactly as prescribed by a doctor.
Common side effects of Pentazocine include dizziness, which is feeling lightheaded, drowsiness, which is feeling sleepy, and nausea, which is feeling sick to the stomach. These effects can vary in severity.
Pentazocine can cause respiratory depression, which is slow or shallow breathing, especially with alcohol. It's not recommended for those with severe breathing problems or allergies to the drug. It can be addictive, so use it exactly as prescribed.
