Warnings and precautions to be aware of prior to taking Cartia XT include the following:
- The medication can slow down the heart rate. This can be a problem in people with certain types of arrhythmias or people taking other medications that can also slow down the heart rate.
- Cartia XT should be used with caution in people with congestive heart failure (CHF). It can cause fluid retention (edema), which can be especially dangerous in people with CHF.

- Cartia XT can increase liver enzymes (found using a blood test), which may be a sign of liver damage.
- The drug is metabolized and removed from the body using the liver and kidneys. If you have liver or kidney disease, Cartia XT may build up in your body. Your healthcare provider should monitor you more closely and may need to decrease your Cartia XT dosage if this is the case.
- Cartia XT can interact with a number of medicines (see Cartia XT Drug Interactions).
- Cartia XT is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy. Talk to your healthcare provider about the risks and benefits of using the drug when pregnant (see Diltiazem and Pregnancy).
- The medication passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking Cartia XT (see Diltiazem and Breastfeeding).
