The injected form of sumatriptan is used to treat
cluster headaches. Self-injection kits are available
so that you can give yourself the shot. Nasal and oral sumatriptan are
available but are less effective than the injectable form. Research is being
done that shows a stronger dose of sumatriptan nasal spray may be more
effective.1
You can take zolmitriptan as a pill (by mouth) or use it as a nasal
spray.
How It Works
Triptans (sometimes referred to as 5-HT-1 receptor agonists) shrink
the blood vessels in the brain, which may relieve pain by reducing pressure
from
inflammation that can occur with cluster headaches.
Triptans may also affect certain brain chemicals that regulate pain.
Why It Is Used
Sumatriptan may be injected to stop cluster headaches.
Zolmitriptan may be sprayed in the nose (nasal spray) to stop
cluster headaches.
How Well It Works
When injected early in a cluster headache, sumatriptan can relieve
headache pain within 5 minutes.2 Up to 90% of people
have reduced headache pain when given a sumatriptan injection as soon as a
cluster headache first begins. The injection also may stop subsequent headaches
in the cycle from developing.3
Nasal and oral sumatriptan are less effective than the injectable
form. But research is being done that shows a stronger dose of sumatriptan
nasal spray may be more effective.1
Zolmitriptan, when used as a nasal spray early in a cluster
headache, can relieve headache pain within 20 minutes. A higher dose may
relieve headache pain even faster.4
The pill form of zolmitriptan (taken by mouth) does not relieve
cluster headache pain as well as injected sumatriptan.5
Side Effects
Triptans may cause side effects such as:
- Nausea.
- Flushing.
- Tingling.
- Dizziness.
- A
feeling of warmth or coldness.
- Sleepiness.
- Burning at
the injection site (with the injected form of
sumatriptan).
- Excessive thirst.
- Frequent
urination.
- Temporary rise in blood pressure.
Side effects usually develop shortly after receiving the medication
and go away within 1 hour. Some people may experience chest pressure or
tightness. This is usually not dangerous.
The U.S. Food and Drug Administration (FDA) has issued a warning
about taking triptans, used for migraines, with SSRIs (selective serotonin
reuptake inhibitors) or SNRIs (selective serotonin/norepinephrine reuptake
inhibitors). Taking these medicines together can cause a serious condition
called serotonin syndrome.
See Drug Reference for a full list of side effects. (Drug Reference
is not available in all systems.)
What To Think About
Triptans should not be used if you have
heart disease, uncontrolled high blood pressure, or are pregnant or
nursing.
Triptans should not be combined with certain other medications,
such as ergotamines.
Triptans can be very expensive, so the cost of treating frequent
cluster headaches can add up. If you are thinking about using triptans to treat
your cluster headaches, you may want to weigh the cost of a triptan against the
cost of other medications, office visits, and time lost from work.
It is important that you do not use triptans on a daily basis to
treat or prevent cluster headaches. Overuse of triptans can cause you to have
more headaches when the medicine wears off. These are called
rebound headaches. If you feel like you need to use
triptans often, talk to your doctor. He or she may have you try a different
medicine.
