John, this is a very interesting question.  (Haven�t seen Dr. Brian�s paper
yet).

Hypertensive crisis is the most common and deadly effect of combining
monoamine oxidase inhibitors MAOIs with certain foods and meds (including
OTC drugs).  Seizures commonly accompany hypertensive crisis and, under
water, will cause drowning.

Off the top of my head (from clinical experience):  The MAOIs rank among the
oldest classes of antidepressant drugs and work by inhibiting the enzyme
monoamine oxidase (as the drug class name indicates).   They are still used
clinically because they often work for patients whose depression is
refractory to newer and �cleaner� antidepressants (Prozac et al).  However,
MAOIs can interact in dangerous ways when combined with certain foods,
medications, or are used in people with some clinical conditions---and they
are highly lethal when used for overdose attempts.

This is a sketchy list of MAOI/food/drug/disease interactions.  Divers who
may be taking these (or any drugs, particularly any medications that act
upon the central nervous system [CNS] *must* consult a
psychiatrist---preferably one who is knowledgeable in dive medicine--before
diving).  These MDs are rare; call DAN.  Be aware, though, that very little
data are available regarding the effects of most medications at depth.  If
you�re taking an MAOI, seek expert opinion before diving, particularly in
cold, deep, overhead, and other stressful environments.

MAOIs are notorious for their interactions with other medications, foods,
and diseases (this is a *short* list):

DRUGS:

*	(�newer� antidepressants such as Prozac, Paxil and other SSRIs; also
Buspar;
*	older tricyclic antidepressants ( Elavil, Nortriptiline, Pamelor and
others),
*	some antihypertensives,
*	some narcotics (Demerol, codeine, morphine, most likely others)
*	Other CNS depressants
*	Stimulants (Sudafed, cocaine, presumably Dexedrine and similar drugs)
*	OTC drugs (cough medicine containing Robitussin (guanethidine),
dextromethorphan [DM], Sudafed) and other catecholamine-inducing meds
*	L-Tryptophan (no longer marketed in the US)
*	Beware �vitamin supplements� or �organic medications�

FOODS:
*	Alcohol, particularly Chianti and other aged red wines
*	foods that contain high levels of tyramine (fava beans, certain aged
cheeses, organ meats), among others

PHYSICAL CONDITIONS:
*	Pheochromocytoma
*	Liver disorders
*	Congestive heart failure
*	Hypertension
*	Epilepsy
*	Hypomania
*	Hypotension
*	In light of recommendations regarding Sudafed�s likelihood of inducing O2
toxicity, take particular care before using EAN when taking MAOIs.  (My
opinion only, based on his is the author�s opinion only).

IMHO, you have an obligation to inform your dive buddy/instructor that you
are taking these (or any) medications.  With certain exceptions, therapeutic
medication use does not preclude diving.  But your partner should be aware
of what you�re taking and why and should know the side effects of your
medications.  Always log your medication use, allergy history, and history
of diseases prominently in your log book---next to your physician�s name and
phone number and your dive insurance card.

More info if I find it---any diving psychiatrists on the list?  Chime in�.

Hope this helps!

Best,

Barbara Dwyer, RN, MA
San Francisco

Subject: question regarding Hyperoxic Seizures

I read with great interest Dr. Brian's paper regarding hyperoxic seizures.
Just for my own clarification Dr. Brian mentions MAO inhibitors  delay the
onset of seizures because it limits the breakdown of catechlomines that
produce hydrogen peroxide.  However it also states that this process
produces or perhaps leaves a surplus of catechlomines that, in turn, cause
an elevation of the catechlomines that could lead to hydrogen peroxide and
subsequently seizure.  I was always of the opinion that MAO inhibitors were
an absolute contraindicator of diving activities.  Given this response, does
this information indicate a change of medical opinion regarding these
medications?  I understand that this issue is a double edge sword, could
anyone clarify?  John Cain

read with
great interest Dr. Brian's paper regarding hyperoxic seizures.  =
Just for
my own clarification Dr. Brian mentions MAO inhibitors  delay the =
onset of
seizures because it limits the breakdown of catechlomines that produce =
hydrogen
peroxide.  However it also states that this process produces or =
perhaps
leaves a surplus of catechlomines that, in turn, cause an elevation of =
the
catechlomines that could lead to hydrogen peroxide and subsequently
seizure.  I was always of the opinion that MAO inhibitors were an =
absolute
contraindicator of diving activities.  Given this response, does =
this
information indicate a change of medical opinion regarding these
medications?  I understand that this issue is a double edge sword, =
could
anyone clarify?  John Cain</span></font><font
