What happens if I miss a dose (Talacen)?

Since acetaminophen and pentazocine is taken as needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Talacen)?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of acetaminophen and pentazocine can be fatal.

Overdose symptoms may include extreme drowsiness, anxiety, nightmares, pinpoint pupils, nausea, vomiting, dark urine, jaundice (yellowing of the skin or eyes), confusion, fainting, weak pulse, coma, blue lips, shallow breathing, or no breathing.

What should I avoid while taking acetaminophen and pentazocine (Talacen)?

This medication may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.

Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.

Avoid drinking alcohol while taking acetaminophen and pentazocine. Alcohol may increase your risk of liver damage while taking acetaminophen.

Smoking tobacco can make acetaminophen and pentazocine less effective.

What other drugs will affect acetaminophen and pentazocine (Talacen)?

Cold or allergy medicine, sedatives, sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by pentazocine. Tell your doctor if you regularly use any of these medicines, or any other narcotic medicine.
