Contact your doctor immediately if you experience chest pain, shortness of breath, or swelling in your ankles, feet, or legs. These could indicate serious heart or lung problems.
Unexpected Side Effects
Report any unusual side effects to your physician, such as dizziness, lightheadedness, nausea, vomiting, or constipation that worsen or persist. Unusual fatigue or changes in your heartbeat also require immediate attention.
Medication Interactions
Inform your doctor about all medications you take, including over-the-counter drugs and supplements. Certain combinations can negatively interact with Diltiazem CD, potentially leading to dangerous consequences. This includes grapefruit juice, which can significantly increase Diltiazem levels in your blood.
Dosage Adjustments
Never alter your dosage without first consulting your doctor. Adjustments must be made based on your individual needs and response to the medication. Ignoring this could negatively impact your health.
Changes in Health Condition
Notify your physician if you develop any new health conditions or if your existing health problems change. This includes changes in blood pressure, kidney or liver function, or the development of any new allergies. Accurate information ensures appropriate management of your treatment.
Lack of Improvement
If your symptoms don’t improve after a reasonable period of taking Diltiazem CD, schedule an appointment with your doctor to discuss alternative treatment options or to investigate underlying issues.
