Ranexa is an angina medication used to treat chronic angina (chest pain) and ischemia symptoms.

Ranolazine is a selective late sodium inhibitor that reduces intracellular calcium in the sodium channel which decreases ventricular wall tension and oxygen consumption. These effects allow Ranexa to relieve symptoms of ischemia, specifically chronic angina.

This angina medication has been found to be effective at decreasing the occurrence and severity of chest pain. Ranexa has a low incidence of adverse effects and can further reduce angina when used in combination with other therapies.

The dose of Ranexa prescribed will vary depending on the individual being treated. Follow all your doctor’s directives and read packaging labels carefully to ensure the best results throughout your treatment.

Can you stop taking Ranexa abruptly?

No, you should not suddenly stop taking Ranexa, especially not without consulting your doctor. This angina medication is designed to prevent the recurrence of chest pain and will not take effect quickly enough to treat an angina attack. This means that it is important to take regular doses so ranolazine can build up and take proper effect and stopping suddenly can cause an increase in chest pain.

Does Ranexa make you tired?

Ranexa has been reported to cause dizziness, light-headedness, and drowsiness. These symptoms are often mild, but you should be careful if you drive or perform any task that requires alertness. Speak with your doctor for more information if you have any concerns.
