00:00
Okay, so we're going to look
at these influenza
antiviral medications.
00:05
They're used to treat influenza
and some can prevented.
00:09
So let's look at it this way
treating it in one column
preventing it in
the other column.
00:16
So there's a big difference,
treat it means I already have it,
prevent it is a oh,
I've been exposed to it
and I'm worried
about not getting it.
00:25
So that's why I'm going
to use those medications.
00:29
Now look at the first column,
we've got the list
of the columns there
and got the trade name for you.
00:34
It's active against
both influenza A and B.
00:38
So go back underline
that generic name.
00:42
That's kind of a
weird sounding one.
00:43
That's why the trade name
will help you remember it?
However on an exam
what you'll see is
the generic name
particularly on the NCLEX exam.
00:53
So make sure you take
that kind of unusual name
and underline it.
00:57
Now something that will help
you as that ends in "VIR".
01:00
That's usually a clue that this
medication is going to treat a virus.
01:05
Now,
let's talk about prevention.
01:08
Now these have activity
against both influenza A and B.
01:12
That's good news.
01:14
Okay,
so you've probably heard these
Tamiflu, Relenza, Rapivab.
01:18
Those are the drugs trade names.
01:21
Go back and look at
their generic names.
01:24
So spend some time
here on this slide
with making sure you
familiarize yourself
with the a generic name
for these medications.
01:31
Look at what category
they belong to
Neuraminidase Inhibitors, okay?
So that's really important
that you remember
these drug names
belong to this category,
And our goal is to
prevent the influenza
from attacking that patient.
01:50
Okay, so when should Olsetamivir
or Tamiflu be started?
Yeah, this is what we
talked about earlier.
01:58
Like these drugs are great.
02:00
But what's the problem
with these drugs
or what's the special
instruction with these drugs?
It's all in the timing.
02:09
It's going to treat influenza.
02:11
The patient can only have
symptoms for 2 days meaning
within 48 Hours of
symptoms starting
the patient needs to go
and see the physician.
02:19
To reach out for
the healthcare team
in order to get this medication
and for it to be effective.
02:25
So for using it for treatment
if it's been longer than
48 hours for symptoms.
02:30
This drug is just really
isn't going to help.
02:33
Now if the patient
has been exposed.
02:35
Whoa, look at this.
02:38
We can use this medication for
both treatment and prophylaxis.
02:43
So somebody in your home
is influenza positive
you get in the right
timing of the window.
02:49
It's within their 48 hours
or them starting symptoms.
02:52
They can take the
medication to treatment.
02:54
You can take the
medication to prevent.
02:57
Hopefully prevent you
contracting influenza.
03:01
So it's got to be within
the same time periods.
03:04
This will be easier
for you to remember
whether you're coming for
treatment or you want prophylaxis.
03:09
You want to make sure that you
get this medication started
within 48 Hours of exposure
or within 48 Hours of symptoms.
03:17
Now if you're doing
it for prophylaxis,
you should start it and
continue for 10 days.
03:21
I know some patients who
keep this medication on hand.
03:25
They have a script in
their home at all times
because someone in the
home has cystic fibrosis,
so they have any hint
that this has happened.
03:33
They all take the
prophylactic medication
to make sure they don't bring
it home to their family member.
03:38
High-risk patients the
cystic fibrosis patient
I talk to you about
would be an example,
nursing home patients.
03:44
They can take this
continuously for up to 42 days
and oftentimes that's
what this family will do
during if it's a really
intense flu going on.
03:54
Okay so usually the
flu is bad news,
but we're looking
with influenza.
03:59
We've got some little
options here right?
As long as you get
treatment quickly.
04:05
So 48 hours is the magic number.
04:08
Two days is all you've got
for an intervention to help.
04:12
The patient is
particularly high risk,
they can take this medication
continuously for 42 days.
04:19
That's six weeks.
04:21
So that's going to
give you hopefully
enough prophylaxis
to get you through
the most dangerous are vulnerable
period for that patient.
04:28
Okay, so make sure you're clear
on which medication
are we talking about?
Right. We're talking about
Tamiflu or Oseltamivir
We know that it's a virus
because we've got that
clue at the end "VIR".
04:43
We know the key point is timing.
04:45
we know I can use it for
treatment or for prophylaxis
we've got somebody
particularly fragile
we can keep them on it
for up to six weeks.
04:54
So back to that timing thing
start a prophylaxis
treatment 12 hours
after symptom onset,
symptom duration should
be cut back by three days.
05:03
So if I was, if I get in there
really early within 12 hours,
you'll probably cut
about three days
off of me failing
really miserable off.
05:11
If it's within 24 hours,
then it's going to
be less than two days
if it's 36 hours
and you're giving me about a better
day in a little bit of change.
05:21
so you see yet has to
be within 48 hours,
but look at the difference if
I'd get it within 12 hours.
05:28
Makes a significant difference
It'll save you a whole day.
05:32
So these drugs can reduce the
symptoms duration and severity.
05:37
So you're still
going to be sick,
but it's not going
to last as long
and you're not going
to feel as bad.
05:42
You also are going
to minimize the risk
of developing complications
after influenza-like
sinusitis and bronchitis and
none of those are fun-itis.
05:52
You don't want, that are no fun.
05:55
Sinusitis really
makes you feel rundown
same thing with bronchitis.
06:00
So we want to make sure
that patients have the
shortest duration of influenza
and the lowest risk
of complications.
06:08
So it takes education.
06:09
Hey, don't just power through,
don't just suffer through this
seek health gets a simple test
to see if your
influenza positive
and the quicker we can
get medication into you,
you'll feel better.
06:21
You'll be back to
normal health quicker
and people are around you
are less likely to also
pick up the influenza.
