How should I take/use this medication?

  • Follow your doctor’s instructions as to how many tablets to take when the attack starts.
  • If your migraine improves but comes back, wait at least 2 hours before taking the next dose. Do not take more than 80mg per day.
  • Do not use eletriptan too frequently (limit to 10 days of use per month), as it can cause medication overuse headache (migraine/headache may worsen). Inform your doctor if you need to take eletriptan to treat more than 3 headaches in a 1 month period.
