I am 10 years post menopausal and I am still taking Imitrex injections regularly! I would seek a second opinion on this. The problem is, studies have only been done on the triptans to age 60 and not beyond so there are no definite guidelines for older people.
However, providing your Doc is happy with your state of health other than your headaches, i.e. you have no heart disease or vascular, disease etc, there may be a possibility of you continuing with the triptans! But please please talk to another Neuro preferably a Headache Specialist about this don't just take them again on my say so!!!
Let me know how you get on with this?
