Description
Carvedilol 12.5mg Tablet primarily acts as a non-selective beta-blocker and alpha-1 adrenergic receptor antagonist. Its mechanism of action involves blocking beta-adrenergic receptors in the heart and peripheral vasculature, leading to decreased cardiac output and reduced peripheral vascular resistance. By blocking beta-1 receptors, carvedilol decreases heart rate and myocardial contractility, resulting in reduced cardiac workload and oxygen demand. Simultaneously, its blockade of alpha-1 receptors causes vasodilation, which lowers blood pressure by decreasing peripheral vascular resistance. This dual action contributes to the medication’s effectiveness in managing hypertension and congestive heart failure, as it improves blood flow, reduces cardiac stress, and helps maintain a stable cardiovascular system.

Drug Interactions
Following are the drug interactions for Carvedilol 12.5mg Tablet:
- Carvedilol can interact with calcium channel blockers (e.g., verapamil, diltiazem), leading to increased risk of bradycardia and heart block.
- Concomitant use with clonidine may result in increased risk of hypotension and bradycardia; abrupt discontinuation of either drug may lead to severe hypertension.
- It may enhance the effects of hypoglycemic agents, including insulin, and increase the risk of hypoglycemia.
- The effects of carvedilol and digoxin may be additive, leading to prolonged heart rate reduction.
- Rifampicin can decrease the effectiveness of carvedilol by inducing its metabolism.
- The use of carvedilol with general anesthetics may result in prolonged hypotension and bradycardia.
- Caution is advised when combining with other medications that block alpha-adrenergic receptors, as this may cause hypotension.
Food Interactions
Following are the food interactions for Carvedilol 12.5mg Tablet:
- Grapefruit and grapefruit juice consumption should be avoided as they can increase Carvedilol levels in the blood, potentially leading to increased side effects, especially those related to the heart.
- Alcohol intake is not recommended as it can increase the risk of low blood pressure and may also enhance the sedative effects of Carvedilol, causing dizziness and drowsiness.
- Caffeinated beverages like coffee or energy drinks should be limited as they can counteract the blood pressure-lowering effect of Carvedilol.
- High-sodium foods should be minimized as Carvedilol is often prescribed to manage blood pressure, and excessive sodium can counteract its effectiveness.
- A balanced diet rich in fruits, vegetables, whole grains, and lean proteins is generally recommended to support overall cardiovascular health while taking Carvedilol.
- Avoid excessive consumption of foods rich in tyramine, such as aged cheeses, cured meats, and certain types of beer, as they can interact with Carvedilol and lead to a sudden increase in blood pressure.
- Always consult your healthcare provider for specific dietary recommendations based on your health condition and medication regimen.
Storage/Disposal
Carvedilol 12.5mg Tablets should be stored in a cool and dry place, preferably at room temperature, away from direct exposure to sunlight, moisture, and heat. The original container should be used to keep the tablets protected from external factors and to maintain their integrity. It is crucial to pay attention to the expiration date on the packaging and discard any unused or expired tablets appropriately. When disposing of the medication, avoid flushing it down the toilet or pouring it into drainage systems. Instead, consult a pharmacist or healthcare professional for guidance on proper disposal methods to ensure environmental safety. Additionally, keep the medication out of children’s reach to prevent accidental consumption.
Quick Tips, if any
Following are the quick tips for Carvedilol 12.5mg Tablet:
- Consult your doctor before starting this medication and provide your complete medical history.
- Take the tablet as directed by your doctor, usually twice a day with food.

Laboratory Screening
Carvedilol is a prescription drug mainly used to treat high blood pressure and heart disease. To ensure safe usage and monitor any potential side effects, your doctor may recommend some lab tests while you take this medication. These tests can also help adjust the dosage as needed. Firstly, regular blood pressure checks are important to assess Carvedilol’s effectiveness and adjust the dosage accordingly. Additionally, since Carvedilol can impair kidney function, particularly in patients with existing kidney issues, regular kidney function tests are advised to monitor kidney health and adjust the treatment plan if necessary. Because Carvedilol can influence electrical activity in the heart, electrocardiogram (ECG) recordings may be recommended to monitor the heart’s rhythm and conduction. This is particularly crucial if you have a history of heart problems or arrhythmias. Given that Carvedilol is metabolized by the liver, regular liver function tests may be advised to ensure the drug does not cause liver damage. Moreover, since Carvedilol can affect cholesterol levels, regular checks for cholesterol and triglyceride levels in the blood are recommended to ensure it doesn’t cause a rise in lipid levels, which could increase the risk of stroke or heart attack. For diabetics, frequent checks of blood sugar levels are advised, as Carvedilol can cause low blood pressure, which can adversely affect blood sugar control. Finally, depending on your medical conditions, age, other medications, and severity, the frequency and type of lab tests required while taking Carvedilol may vary.
