Patients with liver disease should exercise caution when using Calan (verapamil). Verapamil is primarily metabolized by the liver. Impaired liver function can lead to reduced metabolism and increased drug levels in the body, potentially causing adverse effects.
Dosage Adjustments
Your doctor needs to carefully assess your liver function before prescribing Calan and may adjust your dosage accordingly. Regular monitoring of your liver function and blood verapamil levels might be necessary. Don’t adjust your dosage without your doctor’s guidance.
Specific Liver Conditions
- Cirrhosis: Calan should be used with extreme caution in patients with cirrhosis. The significantly reduced liver function significantly increases the risk of adverse effects.
- Hepatitis: Similar caution is advised for patients with active hepatitis. The inflammation of the liver can further impair its ability to metabolize verapamil.
- Other Liver Diseases: Any form of significant liver impairment necessitates careful monitoring and potential dosage adjustments.
Monitoring for Side Effects
Closely monitor yourself for side effects such as dizziness, nausea, constipation, and heart rhythm abnormalities. Report any unusual symptoms to your physician immediately. Early detection can prevent serious complications.

Allergic Reactions and Hypersensitivity to Calan
Avoid Calan if you have a known allergy to verapamil or any of its components. This includes the inactive ingredients listed in the medication’s packaging.
Symptoms of an allergic reaction can range from mild to severe. Mild reactions might present as skin rash, itching, or hives. More serious reactions, requiring immediate medical attention, can involve swelling of the face, lips, tongue, or throat (angioedema), difficulty breathing, or a sudden drop in blood pressure.
Hypersensitivity reactions, a broader category encompassing allergic responses, might manifest differently. Look for symptoms like fever, joint pain, or unusual fatigue alongside skin changes.
If you experience any of these symptoms after taking Calan, discontinue use immediately and seek medical advice. Report all symptoms, no matter how minor they may seem, to your doctor or pharmacist. Early intervention is key to managing potential complications.
Before starting Calan, inform your healthcare provider of any past allergic reactions or sensitivities you have. This helps them assess the potential risk and determine if Calan is a suitable medication for you.
Specific Patient Groups and Calan Contraindications
Patients with sick sinus syndrome or sinoatrial (SA) node dysfunction should avoid Calan, as it can worsen bradycardia (slow heart rate). This includes individuals with a history of heart block, except for type II second-degree or type III atrioventricular (AV) block with a functioning pacemaker. Those with a pacemaker may still experience slowed heart rate, requiring careful monitoring.
Patients with Certain Cardiac Conditions
Calan is contraindicated in patients with severe left ventricular dysfunction, particularly those with low ejection fraction. This is because Calan can negatively impact cardiac contractility. Similarly, avoid Calan in patients experiencing cardiogenic shock, as it could further compromise cardiac output.
Other Contraindications
Hypotension presents a significant contraindication. Calan’s vasodilatory effects can cause a dangerous drop in blood pressure, particularly in patients already experiencing hypotension. Severe hepatic or renal impairment also restricts Calan use due to altered drug metabolism and excretion. Pregnant or breastfeeding women should discuss Calan use with their physicians carefully, weighing benefits and risks.
