Discussion Drug Interactions Question

[diyCTB]

I have found that a combination of Metoclopramide and Paroxetine can cause issues:

Serious

• metoclopramide oral + paroxetine oral
  Potential for serious interaction; regular monitoring by your doctor required or alternate medication may be needed
  metoclopramide oral and paroxetine oral both increase affecting serotonin levels in the blood. Too much serotonin is a potentially life-threatening situation. Severe signs and symptoms include high blood pressure and increased heart rate that lead to shock.
  Additional Information: Combination increases risk of serotonin syndrome, neuroleptic malignant syndrome, dystonia, or other extrapyramidal reactions.

My question is when should I stop taking Paroxetine. How many days before CTB? Do I need to find out how long Paroxetine stays in my body?

Thanks.
