Drug Interaction Report

The following interaction applies only if you are using naloxone in an injectable formulation:

naloxone can reverse the effects of pentazocine. If you are a physically dependent patient you may experience withdrawal symptoms. This can cause nausea, vomiting, diarrhea, aches, fever, runny nose, sneezing, nervousness, irritability, shivering, and abdominal cramps. Talk to your doctor if you have any questions or concerns. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Smoking tobacco may reduce the blood levels and effects of pentazocine. Contact your doctor if pentazocine is not adequately controlling your symptoms.

Taking linaclotide with food may increase gastrointestinal side effects such as diarrhea, abdominal pain, and gas. The absorption of any other oral medication you may take can be affected if you develop frequent or severe diarrhea. To reduce the risk of gastrointestinal intolerance, linaclotide should be taken on an empty stomach at least 30 minutes prior to the first meal of the day. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Do not use alcohol or medications that contain alcohol while you are receiving treatment with pentazocine. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. With certain long-acting formulations of narcotic pain medication, consumption of alcohol may also cause rapid release of the drug, resulting in high blood levels that may be potentially lethal. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of pentazocine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
