The oral Imitrex you take one and then you can repeat the dosage in 30 min if it is not effective but you can't take anymore than 2 doses in a 24hr period. I suffer from cluster headache and find the oral imitrex ineffective. If it is not working for you consider talking to your Dr. about switching to a different triptan. I found Frova and Axert worked well. I currently take Zomig (its amazing) and topamax as a preventive.
