Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies, before starting Inderal. This includes prescription drugs like those for heart conditions, asthma, depression, or diabetes.
Potential Drug Interactions
- Clonidine: Combining Inderal with clonidine may cause a significant drop in blood pressure. Digoxin: Inderal can slow the heart rate, potentially increasing the effects of digoxin and leading to toxicity. Your doctor will closely monitor your heart rate and digoxin levels. Insulin and Oral Hypoglycemics: Inderal may mask the symptoms of low blood sugar (hypoglycemia). Monitor blood sugar levels carefully. Beta-blockers (other than Inderal): Avoid using multiple beta-blockers simultaneously. It can result in unwanted side effects. MAO inhibitors: Combining Inderal with MAO inhibitors can cause dangerously low blood pressure. Calcium channel blockers: Concomitant use may increase the risk of hypotension.
Specific Considerations
Inform your doctor if you are taking any medication affecting your liver or kidneys, as Inderal metabolism may be affected. Discuss any alcohol consumption with your physician; alcohol can interact with Inderal and increase its side effects. Before undergoing surgery, clearly inform your anesthesiologist about your Inderal use.
