Ranexa Side Effects

RANEXA (ranolazine) is an anti-anginal medication. It works by improving blood flow to help the heart work more efficiently.

RANEXA is used to treat chronic angina (chest pain). It may be used with beta-blockers, nitrates, calcium channel blockers, anti-platelet therapy, lipid-lowering therapy, ACE inhibitors, and angiotensin receptor blockers. RANEXA is not for use during an acute (emergency) attack of angina.
