Indications  

Corgard is a prescribed medication indicated for the long-term management of angina pectoris. It aids in decreasing chest pain episodes and enhancing exercise capacity. 

Corgard may also be prescribed alone or in combination with other medications to treat high blood pressure, effectively reducing the risk of fatal and nonfatal cardiovascular events, particularly strokes and myocardial infarctions. 

Classified as a beta blocker, Corgard inhibits the action of specific endogenous substances, such as adrenaline (epinephrine), on the heart and blood vessels. This mechanism leads to a reduction in heart rate, blood pressure, and cardiac strain. 

Uses and Dosage 

Before taking Corgard and with every prescription refill, thoroughly review its medication guide and patient information leaflet. For any questions or clarifications, consult your physician or pharmacist. 

Corgard dosage is individualized according to the patient’s medical condition and treatment response. Initial dose is typically low and may be gradually escalated under medical supervision. 

Typically, Corgard is taken once a day as prescribed by the doctor, without regard to food intake.  

For optimal efficacy, take Corgard at consistent times each day. Avoid taking more or less of it or taking it more frequently the prescribed by your doctor. 

Refrain from skipping and discontinuing this medication without seeking medical advice, as abrupt cessation may exacerbate your condition. Dosage may require gradual tapering.

Cautions 

Before starting treatment with Corgard, inform your doctor and pharmacist if you have any known hypersensitivities, especially to: 

• Nadolol 
• Other beta-blockers (e.g., atenolol, propranolol) 
• Any other medications 
• Any of the ingredients present in Corgard tablets 

To ensure Corgard is safe for you, disclose to your physician your medical background, specifically if you have a history of: 

• Certain types of heart rhythm problems (e.g., slow heartbeat, second- or third-degree atrioventricular block) 
• Blood circulation problems (e.g., Raynaud’s disease, peripheral vascular disease) 
• Breathing problems (e.g., asthma, chronic bronchitis, emphysema) 
• Heart failure 
• Kidney disease 
• Mental/mood disorders (e.g., depression) 
• Certain muscle diseases (myasthenia gravis) 
• Skin conditions (e.g., atopy, psoriasis) 
• Overactive thyroid disease (hyperthyroidism) 
• Certain types of tumors (pheochromocytoma) 

Corgard may interact with certain products, including: 

• Alpha blockers (e.g., prazosin) 
• Arbutamine 
• Other beta-blockers (e.g., atenolol) 
• Clonidine 
• Epinephrine 
• Fenoldopam 
• Fingolimod 
• Methyldopa 
• Neuromuscular blocking agents (e.g., tubocurarine) 
• Diuretics (e.g., furosemide) 

To lower the risk of such drug interactions, inform your doctor and pharmacist about all your medicines, including prescription and over-the-counter drugs, other dietary supplements, and herbal products. 

Inspect all your medications’ labels, including allergy or cough-and-cold products, as they may contain sedative components. Consult with your pharmacist if you are using other drowsiness-inducing products, including: 

• Opioid pain or cough relievers (e.g., codeine, hydrocodone) 
• Alcohol 
• Marijuana (cannabis) 
• Sleep or anxiety medications (e.g., alprazolam, lorazepam, zolpidem) 
• Muscle relaxants (e.g., carisoprodol, cyclobenzaprine) 
• Antihistamines (e.g., cetirizine, diphenhydramine) 

Inform your doctor or pharmacist if you are also taking any cough-and-cold products, diet aids, or NSAIDs, such as ibuprofen/naproxen, as they may contain ingredients that can potentially elevate your heart rate or blood pressure. Seek guidance on their safe usage. 

Corgard may hinder blood sugar control in those with diabetes. Follow your doctor’s instructions for monitoring blood sugar levels and promptly report any signs of high blood sugar. Your doctor may need to modify your diabetes treatment, physical activity, or dietary regimen. 

Corgard may increase the risk of hypoglycemia in children, particularly if they experience vomiting or irregular eating habits. To avoid low blood sugar, ensure that children eat regularly. If a child cannot eat regularly, experiences vomiting, or displays symptoms of hypoglycemia (such as sweating or shaking), promptly inform their physician. 

The use of Corgard in older adults may increase their susceptibility to side effects, including dizziness. 

The potential impact of Corgard on unborn babies is uncertain. If taken during pregnancy, this medication may lead to heart or lung issues in newborns. Inform your doctor about your pregnancy status or intentions while using this medicine. 

Nadolol can be transferred into breast milk, posing a risk to a nursing infant. Consult your doctor before taking this medication when nursing an infant.
