Migraine treatment online UK: triptans and when to use them
Prescription migraine tablets in the UK — how triptans work, safety limits and when headache needs urgent assessment.

Migraine is a neurological condition — not just a bad headache. Effective prescription treatment exists, but safety screening excludes cardiovascular contraindications and red-flag headaches.
Recognising migraine vs tension headache
Migraine often includes throbbing pain, nausea, light/sound sensitivity and may have visual aura. It typically lasts 4–72 hours and limits activity.
How acute migraine tablets work
Triptans act on blood vessels and pain pathways in the brain. They work best taken early in the attack — delay reduces effectiveness.
Limits and overuse
Using acute migraine medicines more than 10 days per month can cause medication-overuse headache. Frequent migraines need preventive review with a clinician.
Emergency headache — never treat online
Call 999 or attend A&E for:
- Sudden worst headache of your life
- Headache with weakness, confusion or seizures
- Fever with neck stiffness
- New headache after head injury
Start assessment at migraine treatment.
