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.

Get emergency medical help if you have any of these signs of an allergic reaction to RANEXA: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Call your doctor at once if you have any of these serious side effects:

  • slow, fast, or pounding heartbeats;
  • tremors or shaking;
  • blood in your urine;
  • urinating less than usual or not at all;
  • shortness of breath; or

Less serious RANEXA side effects may include:

  • mild dizziness, spinning sensation, headache;
