The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the Uses and Precautions tabs or the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include: amiodarone, digoxin, fingolimod.
Other medications can affect the removal of diltiazem from your body, which may affect how this medication works. Examples include atazanavir, cimetidine, quinidine, St. John's wort, azole antifungals such as ketoconazole, macrolide antibiotics such as erythromycin, rifamycins including rifabutin and rifampin.
Diltiazem may also affect how your body gets rid of many drugs (such as buspirone, cyclosporine, sirolimus, certain anti-seizure drugs including carbamazepine, certain benzodiazepines including triazolam and midazolam).
Check the labels on all your medicines (such as cough-and-cold products, diet aids, nonsteroidal anti-inflammatory drugs-NSAIDs such as ibuprofen for pain/fever reduction) because they may contain ingredients that could increase your blood pressure or heart rate. Ask your pharmacist about using those products safely.
Cimetidine is a nonprescription drug that is commonly used to treat extra stomach acid. Because cimetidine may interact with diltiazem, ask your pharmacist about other products to treat extra stomach acid.
