The great thing about frova is that it is suppose to keep you pain free and ha free for up to 8 hours.  My dr and I went that route since nothing else was working for me.  Unfortuanatly it was as effective as imitrex for me in the sense that it took 45 min. to kick in and in two hours the ch were back.  I would definitly consider giving this med a try though because it does offer alot of promise.

From my point of view I would like to add that I have had good to excellent success with Frovatriptan as an added preventative medication. Added in addition to 2 x 120 mg Verapamil SR per day, which works good for me most time of the year.

In Dec. 2008 I tried Frovatriptan and got almost pain free with 3 x 2,5 mg per day, one tablet taken every 8 hours. (My body weight is 106 kg) Frova took appr. 2 days to work good.

A couple of weeks ago my cluster headaches went worse and I started with 3 x 2,5 mg/day Frovatriptan again. Same good result as in Dec. 2008: Pain free after two days, just one "little" CH attack per night, during the first two nights.

After five days I stopped taking Frova, a couple of CH attacks came over the weekend but since then not much.

I prefer to use Frova as an additional preventative, rather than to "wait" for CH attacks and abort them with Sumatriptan s.c. Oxygen works very good for me to abort CH attacks.

With Frova I did not notice ANY side effects. In Dec. 2008 blood pressure and ECG were checked after two weeks of taking Frova: Normal results.

My headache specialist agreed to the 3 x 2,5 mg Frova treatment, but recommended regular BP and ECG monitoring.

I have not tried Naratriptan or Eletriptan.
