Specific Precautions and Warnings With RanexaSome warnings and precautions to be aware of prior to taking this drug include the following:
- Ranexa can cause liver problems. In order to monitor for this, your healthcare provider should check your liver enzymes using a basic, standard blood test before you start Ranexa, once every three months for the first year, and then annually thereafter.
- Ranexa can cause a change in the heart rhythm known as QT prolongation. QT prolongation increases the risk for life-threatening arrhythmias; however, studies have not shown that Ranexa increases the risk for arrhythmias. Combining Ranexa with other QT-prolonging medications might increase these risks.
- Ranexa may react with a number of medications (see Ranexa Drug Interactions for more information).
- Ranexa is a pregnancy Category C medication. This means that this drug might not be safe for use during pregnancy, although the full risks are currently unknown. Talk to your healthcare provider about the risks and benefits of using Ranexa during pregnancy (see Ranexa and Pregnancy for more information).
- It is unknown if Ranexa passes through breast milk in humans. Therefore, if you are breastfeeding or plan to start, make sure to talk with your healthcare provider about using Ranexa (see Ranexa and Breastfeeding for more information).
