Can't help you there but your doctor should be able to find quick acting
ones. SSRIs are not the only avenue to explore, depression can be approached
by a number of means other than drugs. Exercise(works very well for some
people), good diet high in omega 3's will help a little, good sunshine
exposure, even mindfulness meditation has shown to be useful. If you were
prescribed the dilantin because of brain trauma then keep in mind that one
of the complications of brain trauma is depression so this may be a separate
issue for you to address. In your case the problem with taking an SSRI at
this time is that these can sometimes cause excitability which may increase
the risk of seizures. There are probably some SSRI's that are safe to take
in this context but I would be first exploring alternative approaches to
depression treatment. In that regard the following sites may be useful:
You need to approach this situation carefully, polypharmacy is best avoided
but sometimes necessary. If the depressive episodes are intermittent and not
affecting your life too much it may better to cope with the same rather than
adding another drug to the regime; there is the possibility that the
depressive episodes will fade away over time. However depression itself is
bad for the brain so don't think that depression is just an emotional state,
sustained (months) major depression is something that must be treated
because time it damages the brain - literally.
Put up a post on sci.med.psychobiology. There are some good psychiatrists
there who may offer some good advice(hopefully much better than I can).
Also, you should state why you started taking dilantin and for how long.
Additionally, if you have suffered depression prior to this current
situation, or there is a family history of depression, make mention of that
