Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

There is minimal semantic drift between the homepage signal and the sub-page content. The homepage H1 ‘FYCOMPA is still available’ serves as a defensive market signal against generics, which is successfully supported by the Patient Stories and Tools pages that emphasize brand-specific support ecosystems. Cross-page messaging remains consistent, focusing on the transition from breakthrough seizures to controlled outcomes.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

hostility, anger,
anxiety, or
irritability; being
suspicious or
distrustful
(believing things
that are not true);
seeing objects or
hearing things that

(perampanel)?

FYCOMPA is a
prescription
medicine used alone
or with other
medicines to treat
partial-onset
seizures with or
without secondarily
generalized seizures
in people with
epilepsy aged 4 and
older and with other
medicines to treat
primary generalized
tonic-clonic
seizures in people
with epilepsy aged
12 and older.

Like other antiepileptic
drugs, FYCOMPA may cause
suicidal thoughts or
actions in a very small
number of people, about
1 in 500. Call your
healthcare provider
right away if you have
any of these symptoms,
especially if they are
new, worse, or worry
you:

thoughts about suicide
or dying; new or worse
depression; feeling
agitated or restless;
trouble sleeping
(insomnia); acting
aggressive; being angry,
or violent; an extreme
increase in activity and
talking (mania); attempt
to commit suicide; new
or worse anxiety; panic
attacks; new or worse
irritability; acting on
dangerous impulses;
other unusual changes in
behavior or mood.
Suicidal thoughts or
actions can be caused by
things other than
medicines. If you have
suicidal thoughts or
actions, your healthcare
provider may check for
other causes.

Pay attention to any
changes especially
sudden changes in mood,
behaviors, thoughts, or
feelings and keep all
follow-up visits with
your healthcare provider
as scheduled. Call your
healthcare provider
between visits as
needed, especially if
you are worried about
symptoms.

Do not stop FYCOMPA
without first talking
with your healthcare
provider.

Stopping suddenly can
cause serious problems
and can cause you to
have seizures more
often.

Before taking FYCOMPA,
tell your healthcare
provider about all of
your medical conditions,
including if you:

have or have had
depression, mood
problems, aggressive or
hostile behavior (for

behavior), suicidal
thoughts or behavior, or
other psychiatric
problems; have liver or
kidney problems; drink
alcohol; have abused
prescription medicines,
street drugs, or alcohol
in the past; are

about registering with
the North American
Antiepileptic Drug
Pregnancy Registry
(1-888-233-2334)(1-888-233-2334); are breastfeeding or

to your healthcare
provider about the best
way to feed your baby if

You should not do both.

Tell your healthcare
provider about all the
medicines you take,

including prescription
and over-the-counter
medicines, vitamins, and
herbal supplements.
Taking FYCOMPA with
certain other medicines
can cause side effects
or reduce either drug’s
benefit. These medicines
include: birth control,
carbamazepine,
phenytoin,
oxcarbazepine, rifampin,
and St. John’s Wort.

What should I avoid
while taking FYCOMPA?

Do not drive, operate
heavy machinery, or do
other dangerous
activities until you
know how FYCOMPA affects
you. FYCOMPA may make
you dizzy, sleepy, or
tired. Do not drink
alcohol or take other
medicines that make you
sleepy or dizzy until
you talk to your
healthcare provider.
FYCOMPA taken with
alcohol or medicines
that cause sleepiness or
dizziness may make your
sleepiness or dizziness
worse. FYCOMPA when
taken with alcohol may
also make your mood
worse, increase anger,
confusion, and
depression.

FYCOMPA may cause other
serious side effects,
including: Dizziness,
vertigo (sense of
spinning), and problems
walking normally.

You may have problems
walking normally if you
are unsteady because you
feel dizzy. These
symptoms can increase
when your dose of
FYCOMPA is increased.
Your risk of feeling
dizzy and having
problems walking
normally may be higher
if you are
elderly;
Sleepiness and
tiredness; Increased
risk of
falls.
Taking FYCOMPA can
increase your chance of
falling. These falls can
cause serious injuries.
Your risk of falling may
be higher if you are
elderly;
A serious allergic
reaction that may
affect your skin or
other parts of your
body such as your
liver, kidneys,
heart, or blood
cells.
This allergic reaction
can be life-threatening
and can cause death.
Call your healthcare
provider right away if
you have: a skin rash,
hives; fever or swollen
glands that do not go
away; swelling of your
face; shortness of
breath; swelling of the
legs; yellowing of the
skin or whites of the
eyes; or dark urine

The most common side
effects of FYCOMPA
include:

dizziness; sleepiness;
tiredness; irritability;
falls; nausea and
vomiting; weight gain;
vertigo (sense of
spinning); problems
walking normally;
problems with muscle
coordination; headache;
bruising; abdominal
pain; anxiety

FYCOMPA is a controlled
substance (CIII) because
it can be abused or lead
to drug dependence. Keep
FYCOMPA in a safe place
to protect it from theft
and never give it to
anyone else because it
may harm them. Selling
or giving away FYCOMPA
is against the law.

report negative side
effects of prescription
drugs to the FDA. Visit

[H3] Learn what to expect with FYCOMPA.

The path to finding the right
antiseizure medication might seem like a
faraway destination, but it could be
closer than you think! Here’s how
FYCOMPA is thought to work:

FYCOMPA works differently from other
antiseizure drugs. It is the first
and only antiseizure medication that
targets a specific receptor in the
brain called “AMPA.” This receptor
plays a role in allowing seizures to
happen. As with many other seizure
medications, the way FYCOMPA works
is not fully understood.

[H2] Navigating new territory

Adjusting to your treatment can
take time, here are some things to
look out for to help you avoid
potential roadblocks.

Record your triggers and keep your
doctor up to date on side effects you
may be experiencing.

[H3]
Common seizure triggers: Do any of
these affect you?
Click on the ones you know
about—and keep an eye on the
others.
It isn’t always easy, but you
may be able to avoid some triggers.

CERTAIN TIMES
Specific times of day or
night

Times of fever or illness

In women, around the
menstrual cycle or other
hormonal changes

CERTAIN STIMULI OR SUBSTANCES
Stress

Drinking alcohol

Flashing bright lights or
patterns

Specific foods or products

Too much caffeine

PHYSICAL HEALTH AND CARE
Not taking medication

Not eating well—low blood
sugar

Not getting enough sleep

Make sure your doctor and care team
are always up to date about your
triggers as well!

[H2] Once you’ve hit the open road

Your journey is just beginning, but
you’re not alone!

Finding your stable dosage is another
step closer to seizure control!‡
Keep taking FYCOMPA as prescribed, stay
connected with your doctor’s
office
and let them know if:

You experience a seizure (it might
be time for a dose adjustment)
You have side effects
You miss a dose more than once
You have questions

‡In clinical trials,
some patients taking FYCOMPA experienced
fewer seizures. Individual results may
vary.

with or without
secondarily generalized
seizures in people with
epilepsy aged 4 and
older and with other
medicines to treat
primary generalized
tonic-clonic seizures in
people with epilepsy
aged 12 and older.

Like other antiepileptic
drugs, FYCOMPA may cause
suicidal thoughts or actions
in a very small number of
people, about 1 in 500. Call
your healthcare provider
right away if you have any
of these symptoms,
especially if they are new,
worse, or worry you:

thoughts about suicide or
dying; new or worse
depression; feeling agitated
or restless; trouble
sleeping (insomnia); acting
aggressive; being angry, or
violent; an extreme increase
in activity and talking
(mania); attempt to commit
suicide; new or worse
anxiety; panic attacks; new
or worse irritability;
acting on dangerous
impulses; other unusual
changes in behavior or mood.
Suicidal thoughts or actions
can be caused by things
other than medicines. If you
have suicidal thoughts or
actions, your healthcare
provider may check for other
causes.

Pay attention to any changes
especially sudden changes in
mood, behaviors, thoughts,
or feelings and keep all
follow-up visits with your
healthcare provider as
scheduled. Call your
healthcare provider between
visits as needed, especially
if you are worried about
symptoms.

Do not stop FYCOMPA without
first talking with your
healthcare provider.

Stopping suddenly can cause
serious problems and can
cause you to have seizures
more often.

Before taking FYCOMPA, tell
your healthcare provider
about all of your medical
conditions, including if
you:

have or have had depression,
mood problems, aggressive or
hostile behavior (for
example, homicidal
behavior), suicidal thoughts
or behavior, or other
psychiatric problems; have
liver or kidney problems;
drink alcohol; have abused
prescription medicines,
street drugs, or alcohol in
the past; are pregnant or
plan to become pregnant. It
is not known if FYCOMPA will
harm your unborn baby. If
you become pregnant while
taking FYCOMPA, talk to your
healthcare provider about
registering with the North
American Antiepileptic Drug
Pregnancy Registry
(1-888-233-2334)(1-888-233-2334); are breastfeeding or plan
to breastfeed. Talk to your
healthcare provider about
the best way to feed your
baby if you take FYCOMPA and
to decide if you will take
FYCOMPA or breastfeed. You
should not do both.

Tell your healthcare
provider about all the
medicines you take,

including prescription and
over-the-counter medicines,
vitamins, and herbal
supplements. Taking FYCOMPA
with certain other medicines
can cause side effects or
reduce either drug’s
benefit. These medicines
include: birth control,
carbamazepine, phenytoin,
oxcarbazepine, rifampin, and
St. John’s Wort.

What should I avoid while
taking FYCOMPA?

Do not drive, operate heavy
machinery, or do other
dangerous activities until
you know how FYCOMPA affects
you. FYCOMPA may make you
dizzy, sleepy, or tired. Do
not drink alcohol or take
other medicines that make
you sleepy or dizzy until
you talk to your healthcare
provider. FYCOMPA taken with
alcohol or medicines that
cause sleepiness or
dizziness may make your
sleepiness or dizziness
worse. FYCOMPA when taken
with alcohol may also make
your mood worse, increase
anger, confusion, and
depression.

FYCOMPA may cause other
serious side effects,
including: Dizziness,
vertigo (sense of spinning),
and problems walking
normally.

You may have problems
walking normally if you are
unsteady because you feel
dizzy. These symptoms can
increase when your dose of
FYCOMPA is increased. Your
risk of feeling dizzy and
having problems walking
normally may be higher if
you are elderly;
Sleepiness and
tiredness; Increased
risk of falls.
Taking FYCOMPA can increase
your chance of falling.
These falls can cause
serious injuries. Your risk
of falling may be higher if
you are elderly;
A serious allergic
reaction that may affect
your skin or other parts
of your body such as
your liver, kidneys,
heart, or blood cells.
This allergic reaction can
be life-threatening and can
cause death. Call your
healthcare provider right
away if you have: a skin
rash, hives; fever or
swollen glands that do not
go away; swelling of your
face; shortness of breath;
swelling of the legs;
yellowing of the skin or
whites of the eyes; or dark
urine

The most common side effects
of FYCOMPA include:

dizziness; sleepiness;
tiredness; irritability;
falls; nausea and vomiting;
weight gain; vertigo (sense
of spinning); problems
walking normally; problems
with muscle coordination;
headache; bruising;
abdominal pain; anxiety

seizures with or
without secondarily
generalized seizures
in people with
epilepsy aged 4 and
older and with other
medicines to treat

Like other antiepileptic
drugs, FYCOMPA may cause
suicidal thoughts or
actions in a very small
number of people, about
1 in 500. Call your
healthcare provider
right away if you have
any of these symptoms,
especially if they are
new, worse, or worry
you:

thoughts about suicide
or dying; new or worse
depression; feeling
agitated or restless;
trouble sleeping
(insomnia); acting
aggressive; being angry,
or violent; an extreme
increase in activity and
talking (mania); attempt
to commit suicide; new
or worse anxiety; panic
attacks; new or worse
irritability; acting on
dangerous impulses;
other unusual changes in
behavior or mood.
Suicidal thoughts or
actions can be caused by
things other than
medicines. If you have
suicidal thoughts or
actions, your healthcare
provider may check for
other causes.

Pay attention to any
changes especially
sudden changes in mood,
behaviors, thoughts, or
feelings and keep all
follow-up visits with
your healthcare provider
as scheduled. Call your
healthcare provider
between visits as
needed, especially if
you are worried about
symptoms.

Do not stop FYCOMPA
without first talking
with your healthcare
provider.

Stopping suddenly can
cause serious problems
and can cause you to
have seizures more
often.

Before taking FYCOMPA,
tell your healthcare
provider about all of
your medical conditions,
including if you:

have or have had
depression, mood
problems, aggressive or
hostile behavior (for

behavior), suicidal
thoughts or behavior, or
other psychiatric
problems; have liver or
kidney problems; drink
alcohol; have abused
prescription medicines,
street drugs, or alcohol
in the past; are

provider about all the
medicines you take,

including prescription
and over-the-counter
medicines, vitamins, and
herbal supplements.
Taking FYCOMPA with
certain other medicines
can cause side effects
or reduce either drug’s
benefit. These medicines
include: birth control,
carbamazepine,
phenytoin,
oxcarbazepine, rifampin,
and St. John’s Wort.

What should I avoid
while taking FYCOMPA?

Do not drive, operate
heavy machinery, or do
other dangerous
activities until you
know how FYCOMPA affects
you. FYCOMPA may make
you dizzy, sleepy, or
tired. Do not drink
alcohol or take other
medicines that make you
sleepy or dizzy until
you talk to your
healthcare provider.
FYCOMPA taken with
alcohol or medicines
that cause sleepiness or
dizziness may make your
sleepiness or dizziness
worse. FYCOMPA when
taken with alcohol may
also make your mood
worse, increase anger,
confusion, and
depression.

FYCOMPA may cause other
serious side effects,
including: Dizziness,
vertigo (sense of
spinning), and problems
walking normally.

You may have problems
walking normally if you
are unsteady because you
feel dizzy. These
symptoms can increase
when your dose of
FYCOMPA is increased.
Your risk of feeling
dizzy and having
problems walking
normally may be higher
if you are
elderly;
Sleepiness and
tiredness; Increased
risk of
falls.
Taking FYCOMPA can
increase your chance of
falling. These falls can
cause serious injuries.
Your risk of falling may
be higher if you are
elderly;
A serious allergic
reaction that may
affect your skin or
other parts of your
body such as your
liver, kidneys,
heart, or blood
cells.
This allergic reaction
can be life-threatening
and can cause death.
Call your healthcare
provider right away if
you have: a skin rash,
hives; fever or swollen
glands that do not go
away; swelling of your
face; shortness of
breath; swelling of the
legs; yellowing of the
skin or whites of the
eyes; or dark urine

The most common side
effects of FYCOMPA
include:

dizziness; sleepiness;
tiredness; irritability;
falls; nausea and
vomiting; weight gain;
vertigo (sense of
spinning); problems
walking normally;
problems with muscle
coordination; headache;
bruising; abdominal
pain; anxiety

FYCOMPA is a controlled
substance (CIII) because
it can be abused or lead
to drug dependence. Keep
FYCOMPA in a safe place
to protect it from theft
and never give it to
anyone else because it
may harm them. Selling
or giving away FYCOMPA
is against the law.

You are encouraged to
report negative side
effects of prescription
drugs to the FDA. Visit
