Phenytoin (dilantin): uses
anticonvulsant, antiarrythmic, trigeminal neuralgia management.
Phenytoin (dilantin): nutr implications
long-term therapy may cause anticonvulsant osteomalacia.
Calcium supps may decrease dilantin absorption.
Carnitine status may decline
Hypoalbuminemia may increase effects.
Phenytoin (dilantin): Vit implications
consider prophylactic ssupplimentation of vit D. Vit D2 more effective treatment than D3.
folate (B9) status decline, use minimum amt of folate supp to control def. as folate may decrease anticonvulsant effect of dilantin. 800 μg/day may increase seizure frequency in some cases.
Biotin (B7/H) status may decline.
High doses of vitamin B-6 may decrease the anticonvulsant effect.
Phenytoin (dilantin): TF
•TF w/ most formulas may result in subtherapeutic level of dilantin at a standard dose.

Antidepressant which inhibits MAO and results in accumulation of neurotransmitters such as dopamine, epinephrine, norepinephrine, and serotonin in the body
Lithium (carbolith): type & names
Lithium (carbolith, duralith, lithane)
Lithium: actions
- Management of bipolar disorder (manic depression)
- Antimanic
- Antidepressant
- Alters cation transport in nerves and neurotransmitter reuptake
Lithium: implications
•Keep a steady fluid and sodium intake.
•Hyponatremia increases retention risk of lithium toxicity- vomiting, diarrhea, slurred speech, muscular incoordination and weakness, and drowsiness.
•High sodium intake may cause a decrease in lithium levels and decrease its effect.
Lithium: herbs
- Weight gain may occur
- Psyllium may cause decrease in serum lithium concentration
- Gingseng may promote mania
