• If you are to undergo any surgical intervention that requires general anesthesia, you must inform your doctor and the anesthesiologist about the treatment with Cronodine.
• If you have liver or kidney disease or are elderly: since there are no available data in these patients, Cronodine should be used with caution.

• The use of diltiazem has been associated with skin reactions. Your doctor will evaluate these symptoms and indicate the measures to take.

• Since the therapeutic effect has not been compared between the different specialties with diltiazem in the form of delayed-release capsules, it is not recommended to substitute one for another, except for explicit recommendation from the prescribing doctor.
