About Ranexa

Ranexa is used to treat adults with chronic chest pain (angina). Ranexa can cause a serious heart beat problem called QT prolongation. Because of this problem, Ranexa should only be used after other angina medicines have not relieved chest pain symptoms. Ranexa should be used with amlodipine (Norvasc), beta blocker medicines, or nitrate medicines. Ranexa does not relieve sudden chest pain.

Chronic chest pain (angina) is caused by not enough blood flow to the heart. Ranexa has not been studied in children.

Surprpising experience with Ranexa

I very recently was prescribed Ranexa by my Cardiologist. I took the medication as directed, one pill - 500 mg in the A.M and one 500 mg pill in the P.M. I did this for four and one-half (4 1/2) days. I felt fine . Noticed no difference whatsoever. I had read the indications about side effects. No where did I see anything to do with driving a car. On the fourth day I had a long trip to my GP (he is located 42 miles one way, away). I started almost immediately weaving in my own lane and a few times ran over the right side fog line and several times over the middle yellow line including a double yellow line. I kept wondering what was wrong. I "felt" fine otherwise. At the doctors, I had a magazine "slip" out of my hand a couple times, I tried to write a note and it was completely illegible - than I thought that perhaps I was actually having a stroke. When I saw the Dr. and told him all this, and showed him my note pad, he said to STOP the Ranexa immediately. I was having side effects to the Ranexa. I had no choice but to drive myself home after our office visit was concluded. Again, but more exaggerated and more often I experienced what I had on the way over. Talk about scary!!! In my mind I was fine but my body took over and I was not fine. I did not drive for a couple days and I am alright now. Have to find out what is nextom so far as my next medication. Needless to say, I am slightly "gun shY". Read and then read some more.And for God Sakes, DO NOT stay on the highway as I foolishly did.:confused:http://www.iddb.org/forums/images/smilies/confused.gif
