For many years, the tricyclics were the most popular antidepressants. Although superseded today by the less side-effect prone selective serotonin reuptake inhibitors (SSRIs), they are still used in certain cases.
Antidepressants in this family include:
- Amitriptyline hydrochloride (Elavil)
- Amoxapine (Asendin)
- Clomipramine hydrochloride (Anafranil)
- Desipramine hydrochloride (Norpramin)
- Doxepin hydrochloride (Sinequan)
- Imipramine (Tofranil)
- Nortriptyline hydrochloride (Aventyl, Pamelor)
- Protriptyline hydrochloride (Vivactil)
- Trimipramine maleate (Surmontil)
- and others
Supplementation Possibly Helpful
Preliminary evidence suggests that tricyclic antidepressants might deplete the body of coenzyme Q 10 (CoQ 10 ), a substance that appears to be important for normal heart function. ]]>1,2]]> Based on this observation, it has been suggested (but not proved) that CoQ 10 supplementation might help prevent the heart-related side effects that can occur with the use of tricyclic antidepressants.

Possible Dangerous Interactions
Based on one case report ]]>3]]> and our general knowledge about the actions of these supplements, taking any of these in combination with some tricyclic antidepressants could conceivably present a risk of elevating serotonin levels too high.
Possible Harmful Interaction
St. John’s wort might decrease the effectiveness of tricyclic antidepressants by reducing blood levels of the drug. ]]>4-5]]> Conversely, if you are taking St. John's wort already and your physician adjusts your dose of medication, suddenly stopping the herb could cause blood levels of the drug to rise dangerously high.
