Hi,

5 days ago I started taking St John's wort tablets (one 300mg tablet per
day) and high potency vitamin B tablets. However, I only took them for 3
days (Tuesday, Wedesday and Thursday) because on the Friday morning, on
getting up, I felt slightly dizzy (as in light-headedness). This also
occurred yesterday morning (ie Saturday), and this morning (ie Sunday).

The funny thing is that as the day progresses the dizziness diminishes so
that by the evening I can basically feel nothing at all.

I'm just wondering if the St John's Wort might be responsible at all?? Or
maybe even the high potency B vitamins? But it's been about 60 hours since
the last tablets of St John's Wort and vitamin B complex, and I only was
taking them for 3 days anyway. On the other hand, I have never before felt
dizzy on waking up 3 days in the row.

Any input appreciated.

St John's Wort is known to cause or aggravate dizziness in some people.
Why not try quitting the St John's Wort but continue the B vitamins to
determine which of the two are causing your dizziness.

Dizziness has diminished a great deal today. I will recommence taking the
high potency B vitamins tomorrow. However, there is nothing on the net I
can find which indicated they cause dizziness. Also you just urinate out
any excess vitamins. I'm pretty sure the dizziness was caused by SJW.

Dizziness came back on yesterday and experiencing it today too. I'm
guessing that since it's 5 and a half days since taking my last St John Wort
tablet that it probably isn't that responsible after all? :-( Funny how
my dizziness almost dissappeared completely on Monday though.

Probably not. I don't think the half-life of any SJW ingredient is
that long. It may be time to see your physician and/or a neurologist.

Don't assume the symptoms of an adverse drug effect
will end on discontinuing a drug.
Sometime enough damage is done that recovery is incomplete or
even nonexistent.

The problem maybe some problem of the inner ear.
