25
generally, HA should be prophylaxed if
they're frequent- using analgesia >15m/mth or 2d/wk severe and disabling short lived- esp with cluster HA
26
what are the principles of HA prophylaxis
use long acting for adherence, in cluster HA- start chronic prophylaxis while on transitional prophylaxis, if pt is attack free for 6-12mths- consider tapering the dose
27
when can you consider tapering dose of HA prophylaxis
if pt is attack free for 6-12mths
28
1st line TTH tx
NSAIDs
29
2nd line TTH tx
caffeine + NSAIDs
30
what should be avoided in trying to treat TTHs
acetaminophen with or without codeine (increased risk of dependency + MOH)
31
do TTH generally require prophylaxis?
no- usually mild- mod + short duration
32
when might prophylaxis be considered fro TTH
if attacks are severe enough to limit ADL frequent (>2-3/wk) analgesics are CI, ineffective, or overused
33
what is commonly used for TTH prophylaxis
amitriptyline (TCAs), may also use venlafaxine and mirtazapine
34
HA response to amitriptyline is usually seen in
2-3wks
35
2 forms of care for migraines
stratified vs stepped acre
36
what is the stratified care model for migarines
Migraine attack Mild disability = simple analgesic Mod- severe disability = triptan
37
describe the stepped care across vs within migraines attacks model
across: Migraine attack → simple analgesics (≥ 3 consecutive attacks with no/ insuff response) → migraine attack → triptans within: Migraine attack → simple analgesic (within same attack with no/ insuff response) → triptan
38
if triptans are not effective/ CI/ not available for migraine tx, what should be used?
ditan or gepant
39
compare ASA and NSAIDs to triptans in efficacy
less effective
40
compare ergotamine and caffeine to triptans in efficacy
less effective
41
NSAIDs, acetaminophen, ASA use should be limited to ____ to avoid MOH
<15d/mth
42
butalbital combination analgesics use should be limited to ___ to avoid MOA and risk of dependency
<10d/mth
43
what is 1st and 2nd line migraine tx
1st line: NSAIDs, APAP, ASA 2nd line: triptans
44
when are triptans indicated in migraines
mod-severe migraines when analgesics + NSAIDs are ineffective and used too frequently
45
triptan AEs
fatigue, dizzinses, drowsiness, paresthesias, N, abdominal pain, chest discomfort
46
absolute CIs to triptns
IHD or any cardiac like sx, stroke or TIA, peripheral vascular disease like ischemic bowel disease, basilar or hemiplegic migraine, use with ergot derivatives and MAOi
47
5 relative CIs to triptns
uncontrolled HPTN, pregnancy or BF, smoking Caution when coadmin with SSRis and SNRIs d/t ↑ risk of serotonin sx
48
triptans should not be used within 24hrs of antoher
triptan or ergot
49
triptans should not be used within ____ of another triptan or ergot
24hrs
50
triptans should be used ____ to avoid MOH
<10d/mth
51
how soon can you repeat a sumatriptan dose
2hrs
52
PO sumatriptan dose is usualy
25-100mg
53
rank the onset speed of sumatriptan formulations
SC >INH >PO
54
sumatriptan ___ is v effective for severe migraines and acute cluster HAs
SC
55
which triptan has the lowest SEs
naratriptan
56
what is the slowest osnet triptan
naratriptan
57
which triptan is good for relief of nausea
rizatriptan
58
________ increases bioavailability of rizatriptan
propranolol
59
what is 3rd line migraine tx
triptans + NSAIDs
60
4th line migraine tx

61
what is a dihydroergotamine
an ergot derivative for migraines
62
ergot derivates AEs

<10d
65
what tx should be avoided for migraine tx
opioids butalbital
66
codeine or tramadol combo analgesics should be used when

calcitonin gene related peptide receptor antagonists
68
ubrogepant and rimegepant are

2hrs in mod-severe migraine
70
lasmiditan is a
ditan
71
how long for lasmiditan to kick in
2hrs in mod-sevre migraine
72
what is a major advantage of lasmiditan
it's not a vasoconstructor
73
AEs of lasmiditan
temporary driving impairment (no driving for 8hrs post dose)
74
when should migraines be prophylaxed
attacks severe enough to limit ADL, frequent, ≥3x attacks/ mth that are resistant to therapy, migraine meds are CI or failed
75
6 classes for migraine prophylaxis
ACEi/ARBs antiseizure meds BB CCB calcitonin gene related peptide antibody TCAs
76
when are calcitonin gene related peptide antibodies used for migraine prophylaxis
only when other agents are ineffective
77
TCAs are preferred for migraine prophylaxis when
pt has depression/ insomnia
78
migraines in the ER are treated with
Sumatriptan SC, metoclopramide IV, prochlorperazine IV, opioids, DHE, meperidine, ketorolac IM/IV (only NSAID parenteral), corticosteroids (IV dex 6-10mg, associated with reduced HA recurrence for up to 3d)
79
why is abortive tx difficult in cluster HAs
challenged by short nature. By the time PO kicks in, it’s already gone
80
3 first line abortive tx in cluster HAs
O2, sumatriptan SC, zolmitriptan IN
81
when is response expected in using O2 to treat cluster Hs
30min
