Imitrex

When and How to Take Imitrex

Some general considerations for when and how to take the medication include:
 
  • Imitrex comes in tablets, a nasal spray, and an injection.
     
  • It should be taken as soon as possible once a migraine starts.
     
  • Swallow the tablets whole with a drink of water or other fluids.
     
  • The nasal spray and injection both come with pamphlets that describe exactly how to use them.
     
  • If your headache comes back or does not go away, you may take a second dose after waiting at least two hours from the time you took the first dose of Imitrex tablets or Imitrex Nasal Spray (or one hour after the first dose of Imitrex Injection). Let your healthcare provider know if the medication does not work completely after one dose.
     
  • For the medicine to work properly, it must be taken as prescribed. It will not work if you stop taking it.
     

Dosing

The dosage your healthcare provider recommends will vary depending on a number of factors, including:
 
  • How you respond to Imitrex
  • Other medical conditions you may have
  • Other medications you may be currently taking.
     
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
