Migraines are a complex debilitating condition affecting over 80 million people in the UK. There is a wide variety of medication available to help treat the condition and it is important to understand the differences before making a decision as to which medication may be better for you.

The most common group of medications are called 5HT1-receptor agonist (“triptans”), most commonly prescribed as sumatriptan (brand name, Imigran) or zolmitriptan (brand name, Zomig). This group of medications work by acting on the 5HT (serotonin) 1B/1D receptors that reverse the temporary widening of the blood vessels in the brain. This alleviates the pain and other symptoms associated with migraine attacks including nausea and sensitivity to light. Choice of medication between the different triptans depends on the severity and regularity of your migraines.

Clinical studies have shown no significant difference in effectiveness between the different triptans. Patients may find some medicines are more effective than others and often it is trial and error before you can determine which will work better for you. Each medication should be tried a minimum of three times before assessing suitability. The good news is that if you found one particular triptan was unsuccessful at treating your migraines, another triptan may be much more useful for providing pain relief.
