Other Comments

Tapentadol dose should be based on an individual patient basis according to severity of pain, previous medication treatment, and ability to monitor patient.

Once the patient is stable on immediate release tablets and no further dose adjustments are required, consideration should be given to the possibility to switching the patient to the prolonged release tablets.

Sudden discontinuation of tapentadol treatment should be avoided to reduce withdrawal symptoms. Discontinuation of tapentadol treatment should be gradual.

Tapentadol should be taken with sufficient liquid with or without food. Tapentadol prolonged release tablets should be swallowed whole and not split or chewed.

Tapentadol treatment should be reviewed on a regular basis.
