Warnings and precautions
Consult your doctor or pharmacist before starting to take Lacerol HTA Retard

- if you have any cardiac arrhythmia (sinus node disease, atrioventricular block) or if you are being treated with other medications used to treat heart conditions (beta blockers, digitalis), as the use of diltiazem in these situations may lead to an excessively slow heart rate (bradycardia),
- if you have low blood pressure (hypotension): treatment with diltiazem may cause a significant drop in blood pressure. Your doctor will inform you about how to avoid symptoms resulting from hypotension and what measures to take if these symptoms occur,
- if you have any liver or kidney disease or are an elderly person, Lacerol HTA Retard should be used with caution, as there is no available data in these patients,
- the use of diltiazem has been associated with skin reactions. Your doctor will assess these symptoms and indicate the measures to be taken.
- if you have a history of heart failure, new difficulty breathing, slow heart rate, or low blood pressure. There have been reports of kidney damage in patients with these conditions; your doctor may need to monitor your kidney function.
