I took Ranexa for a number of years before I had bypass surgery and it allowed me to exercise without experiencing angina. I never associated it with fatigue. Like Ed34 asks, what other drugs are you taking
Ranexa can cause a horrible headache when combined with wine or spirits, I found that out!
Keep us informed.
Hi, most common side effects are dizziness, headache, constipation, and nausea. More serious side effects are changes in heart rhythm. I don't think Ranexa should cause tiredness, it should improve your heart but can take a little time. Are you on any other medications?
