Our doctor said my husband's kidney function wasn't up to par -
creatinine was too high (1.4) and he has some protein in his urine.

She put him on Lisinopril 5mg.  I read the info on this drug and I
don't see anywhere that it's indicated to improve kidney function.  In
fact it warns against using it for people with renal impairment.

I'm really confused.

Another question:  he feels slightly light headed this morning (his
first dose was at bedtime last night).  I took his bp and it was down,
but not a lot (110/63).  Does the light headed feeling eventually go
away?

Yes, I know these are questions for our doctor and I plan to ask her.
The trouble is she's on vacation right now.

thanks.

That drug is mainly a blood pressure pill.  Actually when I took it I
coughed non stop for a year until I convinced my doc to take me off of it.
Talk to another doctor if yours is gone.

Lisinopril is known as an ACE inhibitor - which is an enzyme system
that controls your blood pressure among other things mainly through
the kidneys. It actually is renoprotective - meaning it helps preserve
kidney function. Your husbands Cr is a little high, but is also
depends on your age as to whether that is a problem, and to his body
build.

One of the major side effects to any ACE is orthostatic hypotension -
which is the feeling of being light headed upon standing. This should
normalize within a week though, and he shouldn't suffer from it
anymore. Continue to have him take his doses at night - so that it
doesn't interfere with any problems driving/at work/etc. The cough
that the other user posted about is another major side effect - but it
only happens in about 10-15% of those taking the medication - and your
husband is on a very low dose (mainly because the doc isn't using to
control BP) so I would guess he shouldn't experience any problems.
Over the counter cough medications won't help take away the cough, so
don't waste your money. If he does develop a cough though, you will
need to rule out that it isn't just the common cold. And the final
side effect to worry about is facial swelling, but this one happens in
less than 1% (probably even less than that), and he would have
experienced it by now if it was a problem.

Hope this helps. Your doctor actually has chosen a very good
medication if she is worried about your husbands kidney function

I agree with the other two responses.

Lisinopril is used to treat hypertension, either alone or in combination
with other antihypertensive drugs.

Some people do stop using it because of chronic coughing.

Lisinopril is used as assistive therapy to treat heart failure because it
reduces the pressure that the heart is pumping against. The pressure the
heart is pumping against is called afterload and this use is called
afterload reduction. Afterload reduction improves renal blood flow because
it causes cardiac blood flow to increase.

Lisinopril is used to preserve renal function. For example, it helps
diabetic patients, with or without slight proteinuria, to prevent
progression to readily observable proteinuria and renal disease. It works in
diabetic patients with and without hypertension. It reduces proteinuria and
preserves renal function in patients who already have renal disease.

Lisinopril is used to preserve renal function in hypertensive renal
transplant patients.

1) Sudden dizziness or dizziness on standing are dose related. Reducing the
dose can help to minimize their occurrence and their intensity. The tablets
you have are probably scored and treatment could be started with half a
tablet.

2) The dizziness is accommodated and countered, to some extent, by
biochemical mechanisms operating within the body. It may or may not go away
(depending on the dose, affinity of active agent for sites of action, and
unknown patient factors).

3) Some people reporting dizziness from medications have subsequently fallen
and broken hips, shoulders, and ribs. Others have suffered life-threatening
hematomas and concussions. Therefore, this kind of side effect should never
be minimized when it occurs, especially if it continues or causes falling or
unsteadiness.

Here is a recent internet posting about this issue. In this case, lisinopril
is being used with a thiazide diuretic which can make the situation worse:

I keep getting dizzy, quick blackout and fainting spells since taking this
medication. I also get sweats/chills. I also urinate more and am always
tired. I am thinking it may be from the medication but my doctor says no and
I am not sure I believe him unfortunately. Did anyone else have these spells
when taking lisinopril?
