Warnings for people with certain health conditions

For people with heart problems or chest pain: Rarely, this drug can cause you to have severe chest pain that happens more often or for a longer period of time. Your risk may be higher if you have severe heart disease. This drug may also increase your risk of having a heart attack.

Warnings for other groups

For pregnant women: This drug is a category D pregnancy drug. That means two things:

Tell your doctor if you’re pregnant or plan to become pregnant. If you get pregnant while taking this drug, stop taking it right away and call your doctor. If it’s taken during pregnancy, this drug can harm or end your pregnancy. This drug should be used during pregnancy only if the potential benefit justifies the potential risk.

For women who are breastfeeding: This drug passes into breast milk and may cause side effects in a child who is breastfed. Talk to your doctor if you breastfeed your child. You may need to decide whether to stop breastfeeding or stop taking this medication.
