Your doctor may provide additional information.

In general, the possibility of having suicidal thoughts and behaviors increases in patients with chronic pain. Additionally, some medications for treating depression (affecting the neurotransmitter system in the brain) may increase this risk, especially at the beginning of treatment. Although tapentadol also affects neurotransmitters, through experience in patients it has not been proven to increase this risk.
