In case of an overdose, call your doctor right away. Your doctor may also give naloxone to treat an overdose.

This medicine will add to the effects of alcohol and other CNS depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert.

This effect may last for a few days after you stop using this medicine. Check with your doctor before taking any of the medicines listed above while you are using this medicine.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.
