Question: What causes triptans to become ineffective over time?
Answer:
Full Question:
I have a question concerning the Triptan group
of drugs used for migraine treatment. Does anyone know what causes one or more
of these drugs to become ineffective over time? I used to take Imitrex and it
stopped working for me after a few years. I now take Zomig, but it's not working
as well as it used to; I'm afraid it's going to stop working for me as well. The
question is-why do these medications work so beautifully at first, then after a
while they just stop working?
Answer:
Dear Questioner;
I don't know why either; nor does anyone else in the headache trade. 30-25% of my Migraine patients have to go to another triptan after the first one "quits". I have a rotation schedule to use different triptan for different patterns of Migraine. It is interesting that the two triptans you mention are the shortest half-life triptans on the market.
Good luck,
Teri Robert and John Claude Krusz
