Switch medication from nortriptyline to hypericum.[1] [2]
Stop nortriptyline - Before day 0: gradually reduce dosage of nortriptyline to a maximum of 50 mg/day, when this dosage is > 50 mg/day.
- Day 1: reduce dosage of nortriptyline to 25 mg/day.
- Day 8: reduce dosage of nortriptyline to 10 mg/day.
- Day 15: stop administration of nortriptyline.
Start hypericum- Day 15-22: a wash-out period of one week is necessary.
- Day 23: start administration of hypericum in a dosage of 300 mg three times a day (900 mg/day).
More information- Occurrence of serotonin syndrome is theoretically possible, so caution is necessary.
- Hypericum induces enzymes of the CYP P-450 type and P-gp type.
- Hypericum might have MAO-inhibiting and/or COMT-inhibiting properties.
- Many studies reported that hypericin is the main source of pharmacological effects of hypericum. However the IC50 of hypericin to inhibit MAO A and MAO B is 100- to 1000-fold higher than accessible Cmax values of hypericin after oral administration of hypericum.[3]
