Triptans Explained: A Complete Guide to These Anti-Migraine Drugs
If you're a migraine sufferer and your doctor just prescribed you a triptan, or you're thinking of asking about one, this guide is for you.
Triptans are the most effective class of medications against moderate to severe migraine attacks. But how they work, the differences between molecules, their side effects and contraindications are rarely explained well during a consultation due to time constraints.
This article gives you everything you need to know to use your triptans correctly and have an informed conversation with your doctor about which molecule is right for you.
What is a triptan?
A triptan is a migraine-specific acute treatment. It was designed specifically to stop a migraine attack, unlike standard pain relievers (acetaminophen, ibuprofen) that act on any kind of pain.
Triptans entered the market in 1991 with sumatriptan, the first in the family. They revolutionized migraine care: for the first time, a treatment acted directly on the mechanisms of the attack, not just the pain.
As of 2026, 7 triptans are approved by the FDA in the U.S.:
- Sumatriptan (Imitrex, generic)
- Zolmitriptan (Zomig, generic)
- Rizatriptan (Maxalt, generic)
- Naratriptan (Amerge, generic)
- Eletriptan (Relpax)
- Almotriptan (Axert)
- Frovatriptan (Frova)
How they work
To understand triptans, you first need to know what happens during a migraine attack:
- A trigger activates a cascade in your brain
- The blood vessels of the meninges (the brain's protective layers) dilate
- The trigeminovascular system activates and releases inflammatory neuropeptides (notably CGRP)
- This inflammation produces the characteristic throbbing pain
Triptans act on multiple levels:
- They bind to 5-HT1B receptors on blood vessels → vasoconstriction of the dilated vessels
- They bind to 5-HT1D receptors on nerve endings → inhibition of neuropeptide release (notably CGRP)
- They reduce pain signal transmission at the brainstem level
Result: pain decreases, but so does the nausea, light sensitivity, and sound sensitivity that accompany the attack.
What to expect: efficacy
Triptans are the most effective acute treatments available, but they don't work for 100% of patients:
- Roughly 60-70% of patients experience relief within 2 hours
- About 30-40% become completely pain-free within 2 hours
- 30-40% experience recurrence (the migraine returns within 24 hours)
Important to know: if one triptan doesn't work for you, it doesn't mean none will. Patient response varies between molecules. If sumatriptan is ineffective, your doctor can suggest another triptan before declaring failure.
The 7 triptans: which one for whom
All triptans act on the same receptors, but their profiles differ on 4 criteria: speed of onset, duration of action, tolerability, available forms.
Sumatriptan
The oldest and most prescribed. The only one available in subcutaneous injection, the fastest and most effective form (works in 10 minutes, 90% relief). Also available as tablet, dissolving tablet, nasal spray, and nasal powder.
For whom: severe attacks, attacks with early nausea/vomiting (injection or spray), morning migraines.
Zolmitriptan
Profile similar to sumatriptan, with good brain penetration. Available as tablet, dissolving tablet, and nasal spray.
For whom: alternative to sumatriptan, especially when patient prefers a dissolving form.
Rizatriptan
Fast-acting (30 min) with strong efficacy. Available as standard and dissolving tablet.
For whom: patient wanting fast relief but in oral form.
Naratriptan
Slower onset (1-3h) but longer duration and fewer side effects.
For whom: long-lasting attacks, patients sensitive to side effects of other triptans.
Eletriptan
Considered one of the most effective on "complete pain freedom at 2h." Fast onset.
For whom: patients for whom sumatriptan didn't work.
Almotriptan
Well-tolerated profile, fewer side effects than sumatriptan in several studies.
For whom: patients sensitive to side effects.
Frovatriptan
Triptan with a very long duration (26-hour half-life, vs. 2-6h for others).
For whom: very long attacks, or short-term prevention for menstrual migraine (taken on the days around your period).
How to take a triptan correctly
When to take it
As early as possible at the start of the headache phase. That's the golden rule. The longer you wait, the less effective the triptan will be.
⚠️ Not during the aura phase. If you have migraine with aura, wait until the aura ends and the headache starts before taking the triptan. Taken during the aura, it's less effective.
Our article on ophthalmic migraine details the aura → headache sequence.
If the first dose doesn't work
If pain isn't relieved 2 hours after the first dose: you can take a second dose (unless the label says otherwise — check your specific molecule).
If the migraine comes back hours later (recurrence): a second dose is generally allowed at least 2 hours after the first.
Maximum per 24 hours: generally 2 doses (except sumatriptan injection: 2 injections).
And if it doesn't work at all
If after 2-3 attacks correctly treated with a triptan, no relief is obtained: talk to your doctor. Several strategies exist:
- Try another triptan (patients can respond to one and not another)
- Switch formulation (move from tablet to injection or spray)
- Add an NSAID (e.g., sumatriptan + naproxen, a documented combination that's more effective)
- Consider a preventive treatment if attacks are frequent
Side effects
Triptans are generally well-tolerated, but can cause what's sometimes called "triptan sensations":
Common effects (>1 patient in 10)
- Sensation of warmth or hot flush
- Tingling or pins-and-needles in extremities
- Pressure or tightness sensation (chest, throat, jaw)
- Heaviness, weakness, fatigue
- Dizziness, drowsiness
These effects are usually transient (15-30 minutes) and disappear on their own. They are not dangerous in the vast majority of cases, even if they can be impressive the first time.
Less common effects
- Nausea, dry mouth
- Muscle pain (especially neck)
- Transient blood pressure increase
- Injection site reactions (injectable sumatriptan)
Rare but important to know
- Coronary spasm: extremely rare, but this is what justifies cardiac contraindications
- Serotonin syndrome when combined with certain antidepressants
Important contraindications
Triptans aren't for everyone. Here are the situations where they're prohibited:
Absolute contraindications
- History of heart attack
- History of stroke or TIA (transient ischemic attack)
- Angina, known coronary artery disease
- Uncontrolled high blood pressure
- Peripheral artery disease
- Severe Raynaud's disease
- Severe liver impairment (depends on the molecule)
- Hemiplegic migraine or basilar migraine (rare forms)
- Pregnancy: avoid except in special cases (discuss with your doctor)
Special precautions
- After age 65: cautious use, cardiovascular workup recommended
- Cardiovascular risk factors (smoking, hypertension, diabetes, high cholesterol): a cardiac workup is often required before prescription
- Breastfeeding: possible with certain triptans, to be discussed
Interactions to avoid
- Ergot derivatives (ergotamine, dihydroergotamine): combination prohibited, risk of excessive vasoconstriction. Wait 24 hours between the two.
- Other triptans: don't take 2 triptans within 24 hours
- MAOI antidepressants: dangerous interaction
- SSRIs and SNRIs (common antidepressants): theoretical risk of serotonin syndrome. Real risk is low but worth flagging to your doctor.
The medication overuse trap
Here's the trap many migraineurs fall into without realizing.
The more triptans you take, the more your brain adapts, and the more you can develop a medication overuse headache: your headaches become daily and resist any treatment.
Limit to respect: no more than 8-10 days of triptan per month.
If you find yourself exceeding this threshold, that's the signal you need a preventive treatment, not more triptans.
Our article on why you have a headache every day explains the medication overuse mechanism and how to break out of it.
Triptans: prescription and access
Important access notes:
- In the U.S., all triptans require a prescription (primary care physician or neurologist)
- In the UK, sumatriptan is available over-the-counter at pharmacies under specific conditions, but other triptans require prescription
- Generic versions are available for most molecules, often significantly cheaper than brand names
- Insurance coverage varies widely — check with your provider before filling
You don't need to see a neurologist for a first prescription: your primary care doctor can prescribe a triptan. A neurologist becomes useful if first-line triptans fail, attacks are very frequent, or there's diagnostic uncertainty.
How to evaluate if your triptan works for you
To know if your current triptan is the right one, track the right indicators over your next 5-10 attacks:
- Time between dose and relief (should be under 2h for at least 60% of attacks)
- Complete or partial relief (distinguish "less pain" from "no pain at all")
- Recurrence within 24 hours
- Side effects experienced and their intensity
- Formulation tested (standard tablet, dissolving, spray, injection)
With this data, your doctor can fine-tune the prescription: switch molecule, switch form, adjust dose, or add an NSAID.
That's exactly what we built Mellow for: precisely tracking each treatment's effectiveness on each attack, and showing you YOUR personalized patterns. After a few weeks, you know exactly what works for you, and you arrive at consultations with data, not impressions.
