Imitrex, Maxalt and Zomig are three of the most-prescribed triptans — abortive migraine medicines you take at the first sign of an attack to stop it, not to prevent future ones. All three are selective serotonin (5-HT) receptor agonists that work the same way and come as low-cost generics (sumatriptan, rizatriptan, zolmitriptan), so the practical differences come down to which form you take and how fast that form works. Because triptans narrow blood vessels, per MedlinePlus they all share the same important limit: they aren't safe for people with certain heart or circulation conditions.
There's no single "best" triptan — for a typical migraine the three are broadly comparable, and the honest choice comes down to formulation and onset. Imitrex (sumatriptan) has the widest range of forms, including a nasal spray and a fast-acting under-the-skin injection; Maxalt (rizatriptan) is oral-only but adds a melt-on-the-tongue wafer; Zomig (zolmitriptan) sits in between with tablets, a dissolving tablet and a nasal spray. Because all triptans narrow blood vessels, per MedlinePlus none of the three is safe if you have heart disease, angina, a prior heart attack, irregular heartbeats, a stroke or "mini-stroke," circulation problems, or uncontrolled high blood pressure — and they shouldn't be used more than about 10 days a month (to avoid medication-overuse headache). These are prescription-only — which one and what dose is decided by your prescriber; do not start, stop, or switch on your own. This is general information, not medical advice — ask a pharmacist or doctor.

| Onset | Tablets usually work within about 30–60 minutes (per NHS); the nasal spray and the under-the-skin injection work quicker, with the subcutaneous injection generally the fastest-acting form. | Taken by mouth; works in the usual oral-triptan window (roughly 30 minutes to a couple of hours). No faster nasal or injectable option. | Oral tablet works in the usual oral-triptan window (roughly 30 minutes to a couple of hours); a nasal spray is available when you want faster or nausea-friendly dosing. |
| Formulations | The widest range of the three — tablets, a nasal spray, and a subcutaneous (under-the-skin) injection. | Oral only — a swallowed tablet and an orally disintegrating wafer (Maxalt-MLT) that dissolves in the mouth. No nasal spray or injection. | Tablet, orally disintegrating tablet (Zomig-ZMT), and a nasal spray. No injectable form. |
| Redosing / half-life | Short-acting; if it helped but the headache returns, per MedlinePlus a repeat is allowed after 2+ hours for the tablet/spray (1+ hour for the injection) — but don't redose if the first dose didn't help. Don't exceed the daily max or ~10 treatment days a month. | Short-acting; per MedlinePlus repeat only after 2+ hours if the headache returns and the first dose worked — do NOT redose if the first tablet didn't help. About 10 treatment days a month is the ceiling. | Short-acting; per MedlinePlus a second dose is allowed only after 2+ hours if the headache returns and the first dose helped. Keep to about 10 treatment days a month at most. |
| Prescription? | Yes — prescription-only. | Yes — prescription-only. | Yes — prescription-only. |
| Good to know | The longest-established triptan and the only one here that also comes as a fast-acting under-the-skin injection — useful when a migraine peaks quickly or brings vomiting. | Oral-only, but its Maxalt-MLT wafer melts on the tongue without water — handy when you're nauseated or away from a drink. | The middle option: tablets, a dissolving tablet (Zomig-ZMT), and a nasal spray for faster-than-a-pill relief without needing an injection. |

Imitrex (sumatriptan)
The longest-established triptan and the only one here that also comes as a fast-acting under-the-skin injection — useful when a migraine peaks quickly or brings vomiting.
Maxalt (rizatriptan)
Oral-only, but its Maxalt-MLT wafer melts on the tongue without water — handy when you're nauseated or away from a drink.
Zomig (zolmitriptan)
The middle option: tablets, a dissolving tablet (Zomig-ZMT), and a nasal spray for faster-than-a-pill relief without needing an injection.
All three are effective acute (abortive) migraine treatments that work the same way, so pick by practical fit rather than a "winner": choose the form that suits you — an injection (Imitrex) or a nasal spray (Imitrex or Zomig) for the fastest relief or when nausea makes swallowing hard, Maxalt's dissolve-in-mouth wafer for convenience, or a plain tablet for any of them. Critically, triptans narrow blood vessels, so per MedlinePlus you should not take them if you have heart disease, angina, a prior heart attack, irregular heartbeats, a stroke or "mini-stroke," circulation problems, or uncontrolled high blood pressure — get emergency care for chest tightness or an irregular heartbeat after a dose, and don't use them more than about 10 days a month (to avoid medication-overuse headache). They're abortive, not preventive, and they're prescription-only: which triptan and what dose is your prescriber's call — do not start, stop, or switch on your own, and tell them about SSRI/SNRI antidepressants (serotonin-syndrome risk) or other triptans/ergot medicines.
